Greg Kroah-Hartman 87a6aca504 Revert "tty: Add a new VT mode which is like VT_PROCESS but doesn't require a VT_RELDISP ioctl call"
This reverts commit eec9fe7d1a.

Ari writes as the reason this should be reverted:
	The problems with this patch include:
	1. There's at least one subtlety I overlooked - switching
	between X servers (i.e. from one X VT to another) still requires
	the cooperation of both X servers. I was assuming that KMS
	eliminated this.
	2. It hasn't been tested at all (no X server patch exists which
	uses the new mode).

As he was the original author of the patch, I'll revert it.

David Rientjes 12ee3c0a0a driver core: numa: fix BUILD_BUG_ON for node_read_distance
node_read_distance() has a BUILD_BUG_ON() to prevent buffer overruns when
the number of nodes printed will exceed the buffer length.

Each node only needs four chars: three for distance (maximum distance is
255) and one for a seperating space or a trailing newline.

Fix 82599 link issues during driver load and unload test using multi-speed
10G & 1G fiber modules. When connected back to back sometime 82599 multispeed
fiber modules would link at 1G speed instead of 10G highest speed, due to a
race condition in autotry process involving Tx laser flapping. Move autotry
autoneg-37 tx laser flapping process from multispeed module init setup
to driver unload. This will alert the link partner to restart its
autotry process when it tries to establish the link with the link partner

Vasanthy Kolluri a55a603dae enic: Bug Fix: Fix hardware descriptor reads
The last bit written to a completion descriptor by hardware is the color
bit. Driver must read all other descriptor fields only after reading the
color bit to avoid reading stale descriptor fields.  There is a rmb() after
reading the color bit to avoid any compiler/cpu reordering of the reads.
The color bit is the generation bit that toggles each pass through the
completion descriptor ring.

Implement arch specific arch_get_memory_phys_device function and
initialize phys_device for each memory section.  That way we finally can
tell which piece of memory belongs to which physical device.

This makes s390's /sys/devices/system/memory/memoryX/phys_device display
the correct thing?

Heiko Carstens bc32df0089 memory hotplug: allow setting of phys_device
/sys/devices/system/memory/memoryX/phys_device is supposed to contain the
number of the physical device that the corresponding piece of memory
belongs to.

In case a physical device should be replaced or taken offline for whatever
reason it is necessary to set all corresponding memory pieces offline.
The current implementation always sets phys_device to '0' and there is no
way or hook to change that.  Seems like there was a plan to implement that
but it wasn't finished for whatever reason.

So add a weak function which architectures can override to actually set
the phys_device from within add_memory_block().

Jason Gunthorpe abf35df215 NET: Support clause 45 MDIO commands at the MDIO bus level
IEEE 802.3ae clause 45 specifies a somewhat modified MDIO protocol
for use by 10GIGE phys. The main change is a 21 bit address split into
a 5 bit device ID and a 16 bit register offset. The definition is designed
so that normal and extended devices can run on the same MDIO bus.

Extend mdio-bitbang to do the new protocol. At the MDIO bus level the
protocol is requested by or'ing MII_ADDR_C45 into the register offset.

Make phy_read/phy_write/etc pass a full 32 bit register offset.

This does not attempt to make the phy layer support C45 style PHYs, just
to provide the MDIO bus support.

Tested against a Broadcom 10GE phy with ID 0x206034, and several
Broadcom 10/100/1000 Phys in normal mode.

James Chapman c3259c8a70 l2tp: Fix UDP socket reference count bugs in the pppol2tp driver
This patch fixes UDP socket refcnt bugs in the pppol2tp driver.

A bug can cause a kernel stack trace when a tunnel socket is closed.

A way to reproduce the issue is to prepare the UDP socket for L2TP (by
opening a tunnel pppol2tp socket) and then close it before any L2TP
sessions are added to it. The sequence is

Create UDP socket
Create tunnel pppol2tp socket to prepare UDP socket for L2TP
  pppol2tp_connect: session_id=0, peer_session_id=0
L2TP SCCRP control frame received (tunnel_id==0)
  pppol2tp_recv_core: sock_hold()
  pppol2tp_recv_core: sock_put
L2TP ZLB control frame received (tunnel_id=nnn)
  pppol2tp_recv_core: sock_hold()
  pppol2tp_recv_core: sock_put
Close tunnel management socket
  pppol2tp_release: session_id=0, peer_session_id=0
Close UDP socket
  udp_lib_close: BUG

The addition of sock_hold() in pppol2tp_connect() solves the problem.

For data frames, two sock_put() calls were added to plug a refcnt leak
per received data frame. The ref that is grabbed at the top of
pppol2tp_recv_core() must always be released, but this wasn't done for
accepted data frames or data frames discarded because of bad UDP
checksums. This leak meant that any UDP socket that had passed L2TP
data traffic (i.e. L2TP data frames, not just L2TP control frames)
using pppol2tp would not be released by the kernel.

If we were to dynamically register/unregister leds and have udev or other
daemons handle the leds class uevents, we would be notified of the adding of a
new LED and if the daemon immediately tries to open one of the attributes of
the led device, it would fail with a "no such file or directory" error since
this the attributes are not yet created. Fix this by switching attributes to be
class-wide, such that the driver core will register these attributes with

Anton Vorontsov 0493a4ff10 leds-gpio: fix default state handling on OF platforms
The driver wrongly sets default state for LEDs that don't specify
default-state property.

Currently the driver handles default state this way:

memset(&led, 0, sizeof(led));
for_each_child_of_node(np, child) {
	state = of_get_property(child, "default-state", NULL);
	if (state) {
		if (!strcmp(state, "keep"))
			led.default_state = LEDS_GPIO_DEFSTATE_KEEP;
		...
	}
	ret = create_gpio_led(&led, ...);
}

Which means that all LEDs that do not specify default-state will inherit
the last value of the default-state property, which is wrong.

This patch fixes the issue by moving LED's template initialization into
the loop body.

Felix Fietkau 4fdec031b9 ath9k: fix BUG_ON triggered by PAE frames
When I initially stumbled upon sequence number problems with PAE frames
in ath9k, I submitted a patch to remove all special cases for PAE
frames and let them go through the normal transmit path.
Out of concern about crypto incompatibility issues, this change was
merged instead:

commit 6c8afef551
Author: Sujith <Sujith.Manoharan@atheros.com>
Date:   Tue Feb 9 10:07:00 2010 +0530

    ath9k: Fix sequence numbers for PAE frames

After a lot of testing, I'm able to reliably trigger a driver crash on
rekeying with current versions with this change in place.
It seems that the driver does not support sending out regular MPDUs with
the same TID while an A-MPDU session is active.
This leads to duplicate entries in the TID Tx buffer, which hits the
following BUG_ON in ath_tx_addto_baw():

    index  = ATH_BA_INDEX(tid->seq_start, bf->bf_seqno);
    cindex = (tid->baw_head + index) & (ATH_TID_MAX_BUFS - 1);

    BUG_ON(tid->tx_buf[cindex] != NULL);

I believe until we actually have a reproducible case of an
incompatibility with another AP using no PAE special cases, we should
simply get rid of this mess.

This patch completely fixes my crash issues in STA mode and makes it
stay connected without throughput drops or connectivity issues even
when the AP is configured to a very short group rekey interval.

NeilBrown 627a2d3c29 md: deal with merge_bvec_fn in component devices better.
If a component device has a merge_bvec_fn then as we never call it
we must ensure we never need to.  Currently this is done by setting
max_sector to 1 PAGE, however this does not stop a bio being created
with several sub-page iovecs that would violate the merge_bvec_fn.

So instead set max_segments to 1 and set the segment boundary to the
same as a page boundary to ensure there is only ever one single-page
segment of IO requested at a time.

This can particularly be an issue when 'xen' is used as it is
known to submit multiple small buffers in a single bio.

Ian Munsie 255f5c327e i4l: change magic numbers in Eicon DIVA ISDN driver to symbolic names
Replace references to the '20' magic number found throughout the Eicon
ISDN driver for the length of the station_id field in the T30_INFO struct
with the T30_MAX_STATION_ID_LENGTH symbolic constant.

Ian Munsie 8b4017d8c1 i4l: silence compiler warnings for array access in Eicon DIVA ISDN driver
When compiling this driver, the compiler throws the following warnings:

drivers/isdn/hardware/eicon/message.c:8426: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8427: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8434: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8435: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8436: warning: array subscript is above array bounds
drivers/isdn/hardware/eicon/message.c:8447: warning: array subscript is above array bounds

This arises from the particular semantics the driver is using to write to
the nlc array (static byte[256]).  The array has a length in byte 0
followed by a T30_INFO struct starting at byte 1.

The T30_INFO struct has a number of variable length strings after the
station_id entry, which cannot be explicitly defined in the struct and the
driver accesses them with an array index to station_id beyond the length
of station_id.

This patch merely changes the semantics that the driver uses to access the
entries after the station_id entry to use the original 256 byte nlc array
taking the offset and length of the station_id entry to calculate where to
write in the array, thereby silencing the warning.

Update of fp->tx_bd_cons in bnx2x_tx_int() is not protected by lock, but
barrier() nor smb_mb() in bnx2x_tx_avail() not guarantee we will see

netif_tx_stop_queue(), netif_tx_queue_stopped(), fp->tx_bd_cons = bd_cons

Alex Chiang 78ed8bd294 ACPI: processor: move acpi_get_cpuid into processor_core.c
Enumerating processors (via MADT/_MAT) belongs in the processor core,
which is always built-in, rather than living in the processor driver
which may not be built.

Alex Chiang 2e9d5e4efa ACPI: processor: export acpi_get_cpuid()
Rename static get_cpu_id() to acpi_get_cpuid() and export it.

This change also gives us an opportunity to remove the
#ifndef CONFIG_SMP from processor_driver.c and into a header file
where it properly belongs.

Alex Chiang 4d5d4cd88c ACPI: processor: mv processor_pdc.c processor_core.c
We've renamed the old processor_core.c to processor_driver.c, to
convey the idea that it can be built modular and has driver-like
bits.

Now let's re-create a processor_core.c for the bits needed
statically by the rest of the kernel. The contents of processor_pdc.c
are a good starting spot, so let's just rename that file and
complete our three card monte.

Alex Chiang 0131aa3dd7 ACPI: processor: mv processor_core.c processor_driver.c
The ACPI processor driver can be built as a module. But it has
pieces of code that should always be built statically into the
kernel.

The plan is for processor_core.c to contain the static bits while
processor_driver.c contains the module-like bits.

Since the bulk of the code in the current processor_core.c is
module-like, first step is to rename the file to processor_driver.c

Next step will re-create processor_core.c and cherry-pick out
the static bits.

Russell King 3f17522ce4 Video: ARM CLCD: Better fix for swapped IENB and CNTL registers
On PL111, as found on Realview and other platforms, these registers are
always arranged as CNTL then IENB.  On PL110, these registers are IENB
then CNTL, except on Versatile platforms.

Re-arrange the handling of these register swaps so that PL111 always
gets it right without resorting to ifdefs, leaving the only case needing
special handling being PL110 on Versatile.

Fill out amba/clcd.h with the PL110/PL111 register definition
differences in case someone tries to use the PL110 specific definitions
on PL111.

Thanks Mikael.

Anonymity has some good attributes.
Blame avoidance is one of them.

I've broad shoulders.  It's me, then Dwight Howard...

There might be another few of these where ->name or ->dev
was used before struct device or net_device was registered.
I'll go back and check.

tulip_core has:

	if (tp->flags & HAS_MEDIA_TABLE) {
		sprintf(dev->name, DRV_NAME "%d", board_idx);	/* hack */
		tulip_parse_eeprom(dev);
		strcpy(dev->name, "eth%d");			/* un-hack */
	}

So I don't feel _too_ bad.

tulip_parse_eeprom is done before register_netdev so the logging
there can not use netdev_<level> or dev_<level>(&dev->dev

Borislav Petkov 0e152cd7c1 x86, k8 nb: Fix boot crash: enable k8_northbridges unconditionally on AMD systems
de957628ce changed setting of the
x86_init.iommu.iommu_init function ptr only when GART IOMMU is
found.

One side effect of it is that num_k8_northbridges
is not initialized anymore if not explicitly
called. This resulted in uninitialized pointers in
<arch/x86/kernel/cpu/intel_cacheinfo.c:amd_calc_l3_indices()>,
for example, which uses the num_k8_northbridges thing through
node_to_k8_nb_misc().

Fix that through an initcall that runs right after the PCI
subsystem and does all the scanning. Then, remove initialization
in gart_iommu_init() which is a rootfs_initcall and we're
running before that.

What is more, since num_k8_northbridges is being used in other
places beside GART IOMMU, include it whenever we add AMD CPU
support. The previous dependency chain in kconfig contained

K8_NB depends on AGP_AMD64|GART_IOMMU

which was clearly incorrect. The more natural way in terms of
hardware dependency should be

AGP_AMD64|GART_IOMMU depends on K8_NB depends on CPU_SUP_AMD &&
PCI. Make it so Number One!

Vladimir Zapolskiy d759c3745e mxcmmc: fixed max_seg_size value on initialization
This unpleasant typo appeared while porting the driver from Freescale
original sources, where anyone can easily find the correct version.

Current incorrect version potentially can influence segment and merge
handling in block subsystem via MMC request queue settings.

Julia Lawall 0fbcae222b drivers/char/mmtimer.c: eliminate useless code
The variable x is initialized twice to the same (side effect-free)
expression.  Drop one initialization.

A simplified version of the semantic match that finds this problem is:
(http://coccinelle.lip6.fr/)

// <smpl>
@forall@
idexpression *x;
identifier f!=ERR_PTR;
@@

x = f(...)
... when != x
(
x = f(...,<+...x...+>,...)
|
* x = f(...)
)
// </smpl>

Stefan observed:

  The next x = rb_entry(mn->next, struct mmtimer, list); is preceded by a
  test whether mn->next is NULL.

  Unless that test is redundant too, your patch fixes a potential NULL
  pointer dereference, introduced by commit cbacdd95 "SGI Altix mmtimer:
  allow larger number of timers per node" in 2.6.26.

pci_set_dma_mask (in drivers/pci/pci.c) does the same things that

calls dma_supprted and sets dev->dma_mask.  So we safely change

Peter Tyser 8004fd2ad6 edac: e752x: add dram scrubbing support
Add support to scrub DRAM using the e752x integrated memory scrubbing
engine.  The e7320/7520/e7525 chipsets support scrubbing at one rate while
the i3100 chipset supports a normal and fast rate.

A similar patch was originally sent back in 2008:
http://sourceforge.net/mailarchive/forum.php?thread_name=1204835866.25206.70.camel@localhost.localdomain&forum_name=bluesmoke-devel

This version has the following updates:
- Use 16-bit PCI config cycles to access MCHSCRB register
    e7320/7520/e7525 docs say register is 16bits wide, i3100 says 8.  I
    tested 16bits on the i3100 to be safe.
- Recalcuate and round actual scrub rates

The changes have been tested on an i3100-based board.

Peter Tyser dcca7c3d00 edac: mpc85xx improve SDRAM error reporting
Add the ability to detect the specific data line or ECC line which failed
when printing out SDRAM single-bit errors.  An example of a single-bit
SDRAM ECC error is below:

  EDAC MPC85xx MC1: Err Detect Register: 0x80000004
  EDAC MPC85xx MC1: Faulty data bit: 59
  EDAC MPC85xx MC1: Expected Data / ECC:  0x7f80d000_409effa0 / 0x6d
  EDAC MPC85xx MC1: Captured Data / ECC:  0x7780d000_409effa0 / 0x6d
  EDAC MPC85xx MC1: Err addr: 0x00031ca0
  EDAC MPC85xx MC1: PFN: 0x00000031

Knowning which specific data or ECC line caused an error can be useful in
tracking down hardware issues such as improperly terminated signals, loose
pins, etc.

Note that this feature is only currently enabled for 64-bit wide data
buses, 32-bit wide bus support should be added.

I don't have any 32-bit wide systems to test on.  If someone has one and
is willing to give this patch a shot with the check for a 64-bit data bus
removed it would be much appreciated and I can re-submit with both 32 and
64 bit buses supported.

Peter Tyser 21768639be edac: mpc85xx mask ecc syndrome correctly
With a 64-bit wide data bus only the lowest 8-bits of the ECC syndrome are
relevant.  With a 32-bit wide data bus only the lowest 16-bits are
relevant on most architectures.

Without this change, the ECC syndrome displayed can be mildly confusing,
eg:

  EDAC MPC85xx MC1: syndrome: 0x25252525

When in reality the ECC syndrome is 0x25.

A variety of Freescale manuals say a variety of different things about how
to decode the CAPTURE_ECC (syndrome) register.  I don't have a system with
a 32-bit bus to test on, but I believe the change is correct.  It'd be
good to get an ACK from someone at Freescale about this change though.

Jaya Kumar b32bfc3843 broadsheetfb: support storing waveform
This patch adds waveform storing capability to broadsheetfb. It uses the
firmware class to retrieve the waveform, and the request to initiate the
waveform storing is done via a driver sysfs entry, loadstore_waveform.

Broadsheet is a framebuffer device.  It is slightly different from a
typical framebuffer controller that drives a normal TFT-LCD display.  Most
E-Ink display panels require a waveform in order to function.  That is, in
order to drive the state of a pixel to black, gray, or white, a specific
waveform is utilized.  Basically, that waveform represents the specific
E-field wiggling needed to get the pixel to its optimal state given
current temperature, and its previous state.  TN/IPS-LCDs use a similar
concept but the driving waveform is sufficiently simple that it is
internalized in the TFT source/gate driver.

These E-Ink waveforms are specific to a production batch.  That is, a
batch of display films are produced, then they get characterized and a
waveform is generated for that batch.  Broadsheet, typically, is attached
to its private SPI flash which is then flashed with this waveform.

Users won't be able to see the waveform and typically won't ever need to
know about it.  If however, the display panel attached to broadsheet is
changed out, then they will need to update their waveform.  That would
typically be done at a factory or repair facility rather than by a user.

Florian Tobias Schandinat e17cea3cec viafb: support color depth 15 and 30
Add support for the color depth 15 on IGA1 and 30 on IGA1 and IGA2.  To
allow the usage of those the driver now refuses color depth that are
totally off and otherwise the selection in viafb_check_var is used.
Therefore the first call to this for the first framebuffer was delayed a
bit.  It only enables the new formats if they are requested exactly
(viafb_bpp=15|30).

As this is a new feature, no regressions are expected.  The color depth 15
was successfully tested.  Didn't get anything usable for 30 but that might
be the programs fault.  I would like to get some feedback whether it works
as expected or not if somebody knows a program/configuration where it
should.

Florian Tobias Schandinat 415559fbf2 viafb: rework color setting
This is a rewritten version of viafb_setcolreg.  The hardware register
writes were split up and moved to hw.c where they belong as this is really
low level stuff.  It was made dual fb aware.

Furthermore viafb_setcmap was removed as the problem with 8bpp originated
from a bug in writing multiple color registers at once.  The removal of
viafb_setcmap might introduce a small performance regression but its
certainly better to receive the correct result a bit slower than a garbled
picture fast.  It should give us a working 8bpp mode and is more
extensible than the old hardcoded code.  No other regressions are expected
but as the hardware might be a bit picky it might cause some regressions
in 8bpp mode on some hardware although I doubt that.

Florian Tobias Schandinat bd140691bd viafb: rework color checking
Make color checking a bit more tolerant in what values it allows and more
fine grained to later support 15 and 30 bits formats.  It splits the
filling of the color information in var to a seperate function and sets
some color related values in var that where previously untouched.

This could be a bug fix but at least I don't know any applications that
was fooled by not correctly setting the fields in var.  At least no
regressions are expected.

Florian Tobias Schandinat 4bbac05f8c viafb: remove dead code due to IGA1_IGA2
Some code depended on IGA1_IGA2 which was never set (at least with the
symbolic name).  Remove this dead code although it might one day be useful
to get a hint on how some things might work.  However as this is dead it
is likely full of bugs and would prevent a clean structure (as it has some
very strange things).

Dead code -> no regressions, at least if VIA doesn't do anything very ugly.

Florian Tobias Schandinat daacccd165 viafb: split color mode setting up
This patch splits color mode setting up in seperate functions.  Some
hardware initialization that was previously mixed with it is moved to
viafb_setmode.  As are the calls to the newly created function.  This is
yet another little step towards controlling each IGA on its own.

As this patch really aims too mimic the old behaviour no regressions are
expected.  However I noticed that 8bpp (or 6bpp?) seems actually a bit
broken before and after the patch.

Florian Tobias Schandinat 5c9443ed28 viafb: make viafb_set_par more dual framebuffer compatible
This patch is an attempt to make viafb_set_par work correctly with more
than one framebuffer.  As modesetting is not (yet/easily) possible for
each individual IGA it uses the (normally to be avoided) global variables
viafbinfo{,1} to ensure that each function is called with the correct
values.

This patch (finally) allows usable dual framebuffer setups and should not
affect non dual fb ones.  It works in some (most?) configurations as
sometimes the driver still gets device connections wrong.  It can be worth
to try the devices in reverse order (in viafb_active_dev).

The user experience is still not very nice as:

- on the second fb you'll normally have a garbled picture as long as
  no application draws to it
  goal: auto on/off devices depending on reference counting
- as the whole machinery is always done you can see mode changes also
  in an unaffected framebuffer
  goal: split modesetting up for each individual IGA

Florian Tobias Schandinat ee79d54db4 viafb: video address setting revisited
Set always the correct video address.  Especially do panning right on
multiple IGAs.

This should have no effect on single monitor mode (no SAMM, no dual fb).
For SAMM without dual fb this might break something as I really cannot
image what we are supposed to do for different resolutions with a single
framebuffer as we can't get data out of nowhere (no, they are not set up
in something one would call "expanded").  Previously I got for that funny
colored pictures as the second IGA pointed to video memory that was never
written to.  After the patch it'll work as cloning if the first and second
mode are identical (this was working already without SAMM).  Finally for
dual fb this should push us a step in the right direction.

Florian Tobias Schandinat dd73d6868b viafb: split global index up
This is the first step to remove an artificial global index that was used
in two ways:

1. As a pseudo index in the mode table.  Pseudo as you had to search
   through the table to find the referenced entry.  This was replaced by
   using a pointer to the entry.

2. As a shortcut to compare a combination of horizontal and vertical
   resolution at the same time.

   This was replaced by a "(hres<<16) | vres" which is good enough for
   now and the near future.  If vres or hres become greater than 2^16 this
   might indeed cause problems but this solution allows to split this
   indexing mess up without the requirement to do even more code changes.

This is a big change that will allow more clean ups.  It should be a bit
faster but that is probably not relevant for normal operation.  No
regressions expected but as this is a relatively big step heavy testing is
appreciated.

Albert Herranz 516a824222 sdio: recognize io card without powercycle
SDIO Simplified Specification V2.00 states that it is strongly recommended
that the host executes either a power reset or issues a CMD52 (I/O Reset)
to re-initialize an I/O only card or the I/O portion of a combo card.
Additionally, the CMD52 must be issued first because it cannot be issued
after a CMD0.

With this patch the Nintendo Wii SDIO-based WLAN card is detected after a
system reset, without requiring a complete system powercycle.

Eli Cohen f0dc117abd IPoIB: Fix TX queue lockup with mixed UD/CM traffic
The IPoIB UD QP reports send completions to priv->send_cq, which is
usually left unarmed; it only gets armed when the number of
outstanding send requests reaches the size of the TX queue. This
arming is done only in the send path for the UD QP.  However, when
sending CM packets, the net queue may be stopped for the same reasons
but no measures are taken to recover the UD path from a lockup.

Consider this scenario: a host sends high rate of both CM and UD
packets, with a TX queue length of N.  If at some time the number of
outstanding UD packets is more than N/2 and the overall outstanding
packets is N-1, and CM sends a packet (making the number of
outstanding sends equal N), the TX queue will be stopped.  When all
the CM packets complete, the number of outstanding packets will still
be higher than N/2 so the TX queue will not be restarted.

Fix this by calling ib_req_notify_cq() when the queue is stopped in
the CM path.

Now that the WM831x core has been converted to use genirq for the
interrupt controller there is no need for the client drivers to
use a WM831x-specific API rather than just calling genirq directly.

Also fixes a leak of the IRQ during init failure - the error path
free_irq() was using NULL rather than the driver data as the data
pointer so free_irq() wouldn't have matched.

When reading data from Geyser 2 touchpads used on post Oct 2005 Apple
PowerBooks the driver was casting X and Y coordinates values to
'signed char'. Testing on one of such PowerBooks I have noticed that
touchpad always generates positive values, but some of them are greater
that 127, and thus, when cast to 'signed char' being interpreted as
a negative.

Such bigger values have been observed infrequently, closer to the
edges of a touchpad, so the problem was not very visible.
Nevertheless, the patch would potentially improve touchpad
driver accuracy.

Andrew Blaich e9f08381cb ath5k: fixing retries in ath5k_hw_setup_4word_tx_desc
The rate control algorithm, default is Minstrel for ath5k, determines
the number of retries to use for each rate.  However, there exists in
ath5k_hw_setup_4word_tx_desc (which is called for AR5212 like devices)
a set number of retries defined by AR5K_TUNE_HWTXTRIES.  The set
number of tries is added to the tx_tries0 variable setup by the rate
control algorithm.  This changes the number of retries the rate
control algorithm considers necessary.  By removing the
AR5K_TUNE_HWTXTRIES from the retry calculation the rate control
algorithm is given control over the number of retries.

Felix Fietkau d969847c22 ath9k: fix rate control tx status handling for A-MPDU
Currently the rate control tx status update gets called for every
subframe of an A-MPDU, and ath9k marks the frame with the relevant
status update with an internal flag. This not suitable for rate control
algorithms using the standard mac80211 rate control API, so fix this by
using IEEE80211_TX_STAT_AMPDU for marking the correct frames that
should be processed.

Benoit Papillault 8127fbdc41 ath5k: Fix TX/RX padding for all frames
Currently, the padding position is based on
ieee80211_get_hdrlen_from_skb(). This is not correct since the HW does
padding on RX (and expect the same padding to be present on TX) at the
following position :

- management : 24 + 6 if 4-addr format
- control    : 24 + 6 if 4-addr format
- data       : 24 + 6 if 4-addr format + 2 if QoS
- invalid    : 24 + 6 if 4-addr format

whereas ieee80211_get_hdrlen_from_skb() is :

- management : 24
- control    : 16 except for ACK/CTS where it is 10
- data       : 24 + 6 if 4-addr format + 2 if QoS + 2 if QoS & order
- invalid    : 24

So, correct frames are not affected : management frames do not use
4-addr format, control frames have no body and invalid frames are ...
not valid by definition. However, in order to use monitor interface for
debugging purpose, one must be able to send/receive any frames, be it
correct or not. Such frames are affected by incorrect padding.

Moreover, since padding is added on TX, we need to remove it before
calling ieee80211_tx_status. This affect TX packets received by monitor
interfaces.

It has been tested between an ath5k based card (AR5212) and an ar9170usb
based card (netgear WNDA3100) using a frame generator and a monitor
interface for each card.

v2: Added ath5k_add_padding / ath5k_remove_padding

Bruno Randolf 86415d43ef ath5k: fix I/Q calibration (for real)
I/Q calibration was completely broken, resulting in a high number of CRC errors
on received packets. before i could see around 10% to 20% CRC errors, with this
patch they are between 0% and 3%.

1.) the removal of the mask in commit "ath5k: Fix I/Q calibration
(f1cf2dbd0f)" resulted in no mask beeing used
when writing the I/Q values into the register. additional errors in the
calculation of the values (see 2.) resulted too high numbers, exceeding the
masks, so wrong values like 0xfffffffe were written. to be safe we should
always use the bitmask when writing parts of a register.

2.) using a (s32) cast for q_coff is a wrong conversion to signed, since we
convert to a signed value later by substracting 128. this resulted in too low
numbers for Q many times, which were limited to -16 by the boundary check later
on.

3.) checked everything against the HAL sources and took over comments and minor
optimizations from there.

4.) we can't use ENABLE_BITS when we want to write a number (the number can
contain zeros). also always write the correction values first and set ENABLE
bit last, like the HAL does.

descriptors, otherwise the hardware will sometimes send the frame out on the

antenna and diversity settings (esp.  AR5K_STA_ID1_DEFAULT_ANTENNA).

also i would like to note that antenna diversity does not always work correctly
on 5414 (at least) when only one antenna is connected: for example all frames
might be received on antenna A but still the HW tries to send on antenna B some
times, causing packet loss.

this is both verified with the antenna statistics output of the previous patch

Michael Hennerich 4eb6f91b95 Input: ad7877 - increase pen up imeout
The time interval between consecutive interrupts depends on a number of
tunables: first_conversion_delay, acquisition_time, averaging and foremost
the pen_down_acc_interval.

Since the mod_timer() action for the PEN UP event happens in the
spi_async() callback function, latencies incurred by the spi bus drivers
also need to be taken into account.

So all in all, give the PEN UP event a bit more wiggle room and increase
timeout to 100ms.

The AD7873 is almost identical to the ADS7846; the only difference is
related to the Power Management bits PD0 and PD1.  This results in a
slightly different PENIRQ enable behavior.  For the AD7873, VREF should
be turned off during differential measurements.

So, add the AD7873/43 to the list of driver supported devices, and prevent
VREF usage during differential/ratiometric conversion modes.

Holding the BKL in input_open_file seems pointless because it does not

underlying drivers have proper mutex locking.

This makes input_open_file take the input_mutex when accessing
the table and no lock when calling into the lower function.

Reinette Chatre 1382c71c76 Revert "iwlwifi: Send broadcast probe request only when asked to"
This reverts commit 21b2d8bd2f.

As explained by Johannes:
When we
build a probe request frame in the buffer with the SSID, we could
arrive over the limit of 200 bytes. When we build it in the buffer
without the SSID (wildcard) we don't arrive over 200 bytes, but the
ucode still allows direct probe in addition because it has an internal
buffer that is larger when it inserts the SSID...

Reinette Chatre 1d79e53c56 iwl3945: fix memory corruption
Recent patch "iwlwifi: move 3945 clip groups to 3945 data" exposed a memory
corruption problem. When initializing the clip groups the code was
mistakenly using the iwlagn rate count, not the 3945 rate count. This
resulted in more memory being written than was allocated.

"iwlwifi: move 3945 clip groups to 3945 data" moved the location where the
clip groups are stored and the impact is now severe in that the number of
configured TX queues is modified. Previously the
"temperature" field was overwritten, which did not seem to affect the
operation.

Fix this one instance where wrong rate count was used. I also noticed one
more location where the iwlagn rate count was used to index an iwl3945
array, fix this. I also modified one location that modified the iwlagn rate
count to obtain the iwl3945 rate count ... just use the iwl3945 rate count
directly.

This fixes http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2165 and

Johannes Berg edc1a3a090 iwlwifi: clean up queue/fifo handling
4965 hardware has 7 queues reserved and the
remaining ones used for aggregation, 5000
and higher need to have 10 reserved. This
is not very clear in the code right now,
unfortunately.

Introduce a new IWL_TX_FIFO_UNUSED constant
and make the queue/FIFO mapping arrays able
to hold that value, and change the setup
code to reserve all queues in the arrays
(the queue number is the index) and use the
new unused constant to not map those queues
to any FIFO.

Additionally, clear up the AC/queue mapping
code to be more understandable. The mapping
is the identity mapping right now, but with
the mapping function I think it's easier to
understand what happens there.

Finally, HCCA isn't implemented at all and
I think newer microcode removed it, so let's
remove all mention of it in the code, some
comments remain for 4965.
