LVDS is the first output where dpms on/off and prepare/commit don't
perfectly match. Now the idea behind this special case seems to be
that for simple resolution changes on the LVDS we don't need to stop
the pipe, because (at least on newer chips) we can adjust the panel
fitter on the fly.
There are a few problems with the current code though:
- We still stop and restart the pipe unconditionally, because the crtc
helper code isn't flexible enough.
- We show some ugly flickering, especially when changing crtcs (this
the crtc helper would actually take into account, but we don't
implement the encoder->get_crtc callback required to make this work
properly).
So it doesn't even work as advertised. I agree that it would be nice
to do resolution changes on LVDS (and also eDP) whithout blacking the
screen where the panel fitter allows to do that. But imo we should
implement this as a special case a few layers up in the mode set code,
akin to how we already detect simple framebuffer changes (and only
update the required registers with ->mode_set_base).
Until this is all in place, make our lives easier and just rip it out.
Also note that this seems to fix actual bugs with enabling the lvds
output, see:

The issue is that we stale data in the CPU caches, when we come to
swap-out the object, the CPU may short-circuit the reads from those
cacheline and so corrupt the context object.
Secondary, leaving the context object as being marked in the CPU write
domain whilst on the GPU active list is a bad idea and will throw
warnings later.
Note: Thanks to calling set_to_gtt_domain with write = false and not
setting any gpu write domain when putting a context object onto the
active list (when we switch away from it) the set_to_gtt_domain call
won't block.

Setting dev_mapping (pointer to the address_space structure
used for memory mappings) to the address_space of the first
opener's inode and then failing if other openers come in
through a different inode has a few restrictions that are
eliminated by this patch.
If we already have valid dev_mapping and we spot an opener
with different i_node, we force its i_mapping pointer to the
already established address_space structure (first opener's
inode). This will make all mappings from drm device hang off
the same address_space object.
Some benefits (things that now work and didn't work
before) of this patch are:
* user space can mknod and use any number of device
nodes and they will all work fine as long as the major
device number is that of the drm module.
* user space can even remove the first opener's device
nodes and mknod the new one and the applications and
windowing system will still work.
* GPU drivers can safely assume that dev->dev_mapping is
correct address_space and just blindly copy it
into their (private) bdev.dev_mapping

The most important part of these updates is the IOMMU groups code
enhancement written by Alex Williamson. It abstracts the problem that a
given hardware IOMMU can't isolate any given device from any other
device (e.g. 32 bit PCI devices can't usually be isolated). Devices that
can't be isolated are grouped together. This code is required for the
upcoming VFIO framework.
Another IOMMU-API change written by be is the introduction of domain
attributes. This makes it easier to handle GART-like IOMMUs with the
IOMMU-API because now the start-address and the size of the domain
address space can be queried.
Besides that there are a few cleanups and fixes for the NVidia Tegra
IOMMU drivers and the reworked init-code for the AMD IOMMU. The later is
from my patch-set to support interrupt remapping. The rest of this
patch-set requires x86 changes which are not mergabe yet. So full
support for interrupt remapping with AMD IOMMUs will come in a future
merge window.

enhancement written by Alex Williamson. It abstracts the problem that
a given hardware IOMMU can't isolate any given device from any other
device (e.g. 32 bit PCI devices can't usually be isolated). Devices
that can't be isolated are grouped together. This code is required
for the upcoming VFIO framework.
Another IOMMU-API change written by me is the introduction of domain
attributes. This makes it easier to handle GART-like IOMMUs with the
IOMMU-API because now the start-address and the size of the domain
address space can be queried.
Besides that there are a few cleanups and fixes for the NVidia Tegra
IOMMU drivers and the reworked init-code for the AMD IOMMU. The
latter is from my patch-set to support interrupt remapping. The rest
of this patch-set requires x86 changes which are not mergabe yet. So
full support for interrupt remapping with AMD IOMMUs will come in a
future merge window."

uhid is for the other (transport) part of the pipeline).
It's needed for (and currently being used by) Bluetooth-LowEnergy,
as its specification mandates things we don't want in the kernel.

- there have been quite a few bugs in runtime suspend/resume paths
(probably never reported to actually happen in the wild, but still).

Pull networking changes from David S Miller:
1) Remove the ipv4 routing cache. Now lookups go directly into the FIB
trie and use prebuilt routes cached there.
No more garbage collection, no more rDOS attacks on the routing
cache. Instead we now get predictable and consistent performance,
no matter what the pattern of traffic we service.
This has been almost 2 years in the making. Special thanks to
Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who
have helped along the way.
I'm sure that with a change of this magnitude there will be some
kind of fallout, but such things ought the be simple to fix at this
point. Luckily I'm not European so I'll be around all of August to
fix things :-)
The major stages of this work here are each fronted by a forced
merge commit whose commit message contains a top-level description
of the motivations and implementation issues.
2) Pre-demux of established ipv4 TCP sockets, saves a route demux on
input.
3) TCP SYN/ACK performance tweaks from Eric Dumazet.
4) Add namespace support for netfilter L4 conntrack helpers, from Gao
Feng.
5) Add config mechanism for Energy Efficient Ethernet to ethtool, from
Yuval Mintz.
6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet.
7) Support for connection tracker helpers in userspace, from Pablo
Neira Ayuso.
8) Allow userspace driven TX load balancing functions in TEAM driver,
from Jiri Pirko.
9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with
embedded gotos.
10) TCP Small Queues, essentially minimize the amount of TCP data queued
up in the packet scheduler layer. Whereas the existing BQL (Byte
Queue Limits) limits the pkt_sched --> netdevice queuing levels,
this controls the TCP --> pkt_sched queueing levels.
From Eric Dumazet.
11) Reduce the number of get_page/put_page ops done on SKB fragments,
from Alexander Duyck.
12) Implement protection against blind resets in TCP (RFC 5961), from
Eric Dumazet.
13) Support the client side of TCP Fast Open, basically the ability to
send data in the SYN exchange, from Yuchung Cheng.
Basically, the sender queues up data with a sendmsg() call using
MSG_FASTOPEN, then they do the connect() which emits the queued up
fastopen data.
14) Avoid all the problems we get into in TCP when timers or PMTU events
hit a locked socket. The TCP Small Queues changes added a
tcp_release_cb() that allows us to queue work up to the
release_sock() caller, and that's what we use here too. From Eric
Dumazet.
15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin.

Byte-by-byte transactions are used primarily for accessing I2C devices
with an SMBus controller. For these transactions, for each byte that is
read or written, the SMBus controller generates a BYTE_DONE IRQ. The isr
reads/writes the next byte, and clears the IRQ flag to start the next byte.
On the penultimate IRQ, the isr also sets the LAST_BYTE flag.
There is no locking around the cmd/len/count/data variables, since the
I2C adapter lock ensures there is never multiple simultaneous transactions
for the same device, and the driver thread never accesses these variables
while interrupts might be occurring.
The end result is faster I2C block read and write transactions.
Note: This patch has only been tested and verified by doing I2C read and
write block transfers on Cougar Point 6 Series PCH, as well as I2C read
block transfers on ICH5.

Enable interrupts on more devices. ICH5, ICH7(-M) and ICH10 have been
tested to work OK. ICH8 and ICH9 are expected to work just fine as
they are very close to ICH7 and ICH10.
Ultimately we want to enable this feature on at least every device
since the ICH5, but for now we limit the exposure. We'll enable it for
other devices if we don't get negative feedback.
As a bonus, let the user know when interrupts are used.

Add a new 'feature' to i2c-i801 to enable using PCI interrupts.
When the feature is enabled, then an isr is installed for the device's
PCI IRQ.
An I2C/SMBus transaction is always terminated by one of the following
interrupt sources: FAILED, BUS_ERR, DEV_ERR, or on success: INTR.
When the isr fires for one of these cases, it sets the ->status variable
and wakes up the waitq. The waitq then saves off the status code, and
clears ->status (in preparation for some future transaction).
The SMBus controller generates an INTR irq at the end of each
transaction where INTREN was set in the HST_CNT register.
No locking is needed around accesses to priv->status since all writes to
it are serialized: it is only ever set once in the isr at the end of a
transaction, and cleared while no interrupts can occur. In addition, the
I2C adapter lock guarantees that entire I2C transactions for a single
adapter are always serialized.
For this patch, the INTREN bit is set only for SMBus block, byte and word
transactions, but not for I2C reads or writes. The use of the DS
(BYTE_DONE) interrupt with byte-by-byte I2C transactions is implemented in
a subsequent patch.
The interrupt feature has only been enabled for COUGARPOINT hardware.
In addition, it is disabled if SMBus is using the SMI# interrupt.

(Based on earlier work by Daniel Kurtz.)
Come up with a consistent, driver-wide strategy for event polling. For
intermediate steps of byte-by-byte block transactions, check for
BYTE_DONE or any error flag being set. At the end of every transaction
(regardless of PEC being used), check for both BUSY being cleared and
INTR or any error flag being set. This ensures proper action for all
transaction types.

If an error is detected in the polling loop, abort the transaction and

* BUS_ERR is set if a bus arbitration collision is detected. In other

detects that the SMBDATA is being held low, usually by another SMBus/I2C
master.

the SMBHSTCNT KILL bit).

In the ac.c, power_supply_register()'s return value is not checked.
As a result, the driver's add() ops may return success
even though the device failed to initialize.
For example, some BIOS may describe two ACADs in the same DSDT.
The second ACAD device will fail to register,
but ACPI driver's add() ops returns sucessfully.
The ACPI device will receive ACPI notification and cause OOPS.

Pull powerpc updates from Benjamin Herrenschmidt:
"Notable highlights:
- iommu improvements from Anton removing the per-iommu global lock in
favor of dividing the DMA space into pools, each with its own lock,
and hashed on the CPU number. Along with making the locking more
fine grained, this gives significant improvements in multiqueue
networking scalability.
- Still from Anton, we know provide a vdso based variant of getcpu
which makes sched_getcpu with the appropriate glibc patch something
like 18 times faster.
- More anton goodness (he's been busy !) in other areas such as a
faster __clear_user and copy_page on P7, various perf fixes to
improve sampling quality, etc...
- One more step toward removing legacy i2c interfaces by using new
device-tree based probing of platform devices for the AOA audio
drivers
- A nice series of patches from Michael Neuling that helps avoiding
confusion between register numbers and litterals in assembly code,
trying to enforce the use of "%rN" register names in gas rather
than plain numbers.
- A pile of FSL updates
- The usual bunch of small fixes, cleanups etc...
You may spot a change to drivers/char/mem. The patch got no comment
or ack from outside, it's a trivial patch to allow the architecture to
skip creating /dev/port, which we use to disable it on ppc64 that
don't have a legacy brige. On those, IO ports 0...64K are not mapped
in kernel space at all, so accesses to /dev/port cause oopses (and
yes, distros -still- ship userspace that bangs hard coded ports such
as kbdrate)."

Inside the error handling in lp5523_init_led(), there is a place that
calls to led_classdev_unregister(). When we unregister the LED drivers,
it tries to set the brightness to OFF. In this driver setting the
brightness is done through a work queue and the work queue hasn't been
initialized yet.
The result is that we trigger a WARN_ON() in the __queue_work().
The fix is to move the INIT_WORK() in front of the call to
lp5523_init_led().

Move led_stop_software_blink() code into led_brightness_set() to ensure
software blink timer is stopped and cleared when changing trigger.
Also use led_set_brightness() instead of calling
led_cdev->brightness_set() directly to keep led_cdev->brightness
consistent with current LED status.
This ensure proper cleaning when changing triggers, as without this fix
a LED may be turned off while leaving it's led_cdev->brightness = 1,
leading to an erratic software-blink behaviour.
The problem was easy to reproduce by changing the trigger from "timer"
to "oneshot".

Convert ledtrig-ide-disk code to use the generic API for one-shot LED
blinking.
This patch changes slightly the behaviour of the trigger, as while the
original version kept the LED on under heavy activity, the new one keeps
a constant on-off blink at 1 / (2 * BLINK_DELAY) Hz.

Add two new functions, led_blink_set_oneshot and
led_trigger_blink_oneshot, to be used by triggers for one-shot blink of
led devices.
This is implemented extending the existing software-blink code, and uses
the same timer and handler function.
The behavior of the code is to do a blink-on, blink-off sequence when
the function is called, ignoring other calls until the sequence is
completed so that the leds keep blinking at constant rate if the
functions are called repeatedly.
This is meant to be used by drivers which needs to trigger on sporadic
event, but doesn't have clear busy/idle trigger points.
After the blink sequence the led remains off. This behavior can be
inverted setting the "invert" argument, which blink the led off, than on
and leave the led on after the sequence.

when writing the same value to delay_on or delay_off')

This adds support for three new SoC types:
* The mvebu platform includes Marvell's Armada XP and Armada 370 chips,
made by the mvebu business unit inside of Marvell. Since the same
group also made the older but similar platforms we call "orion5x",
"kirkwood", "mv78xx0" and "dove", we plan to move all of them into
the mach-mvebu directory in the future.
* socfpga is Altera's platform based on Cortex-A9 cores and a lot of
FPGA space. This is similar to the Xilinx zynq platform we already
support. The code is particularly clean, which is helped by the fact
that the hardware doesn't do much besides the parts that are
expected to get added in the FPGA.
* The OMAP subarchitecture gains support for the latest generation,
the OMAP5 based on the new Cortex-A15 core. Support is rather
rudimentary for now, but will be extended in the future.

This branch contains two kinds of updates: Some platforms in the process
of getting converted to device tree based booting, and the platform
specific patches necessary for that are included here. Other platforms
are already converted, so we just need to update the actual device
tree source files and the binding documents to add support for new board
and new drivers.
In the future we will probably separate those into two branches, and
in the long run, the plan is to move the device tree source files out
of the kernel repository, but that has to wait until we have completed
a much larger portion of the binding documents.

Pull the big VFS changes from Al Viro:
"This one is *big* and changes quite a few things around VFS. What's in there:
- the first of two really major architecture changes - death to open
intents.
The former is finally there; it was very long in making, but with
Miklos getting through really hard and messy final push in
fs/namei.c, we finally have it. Unlike his variant, this one
doesn't introduce struct opendata; what we have instead is
->atomic_open() taking preallocated struct file * and passing
everything via its fields.
Instead of returning struct file *, it returns -E... on error, 0
on success and 1 in "deal with it yourself" case (e.g. symlink
found on server, etc.).
See comments before fs/namei.c:atomic_open(). That made a lot of
goodies finally possible and quite a few are in that pile:
->lookup(), ->d_revalidate() and ->create() do not get struct
nameidata * anymore; ->lookup() and ->d_revalidate() get lookup
flags instead, ->create() gets "do we want it exclusive" flag.
With the introduction of new helper (kern_path_locked()) we are rid
of all struct nameidata instances outside of fs/namei.c; it's still
visible in namei.h, but not for long. Come the next cycle,
declaration will move either to fs/internal.h or to fs/namei.c
itself. [me, miklos, hch]
- The second major change: behaviour of final fput(). Now we have
__fput() done without any locks held by caller *and* not from deep
in call stack.
That obviously lifts a lot of constraints on the locking in there.
Moreover, it's legal now to call fput() from atomic contexts (which
has immediately simplified life for aio.c). We also don't need
anti-recursion logics in __scm_destroy() anymore.
There is a price, though - the damn thing has become partially
asynchronous. For fput() from normal process we are guaranteed
that pending __fput() will be done before the caller returns to
userland, exits or gets stopped for ptrace.
For kernel threads and atomic contexts it's done via
schedule_work(), so theoretically we might need a way to make sure
it's finished; so far only one such place had been found, but there
might be more.
There's flush_delayed_fput() (do all pending __fput()) and there's
__fput_sync() (fput() analog doing __fput() immediately). I hope
we won't need them often; see warnings in fs/file_table.c for
details. [me, based on task_work series from Oleg merged last
cycle]
- sync series from Jan
- large part of "death to sync_supers()" work from Artem; the only
bits missing here are exofs and ext4 ones. As far as I understand,
those are going via the exofs and ext4 trees resp.; once they are
in, we can put ->write_super() to the rest, along with the thread
calling it.
- preparatory bits from unionmount series (from dhowells).
- assorted cleanups and fixes all over the place, as usual.
This is not the last pile for this cycle; there's at least jlayton's
ESTALE work and fsfreeze series (the latter - in dire need of fixes,
so I'm not sure it'll make the cut this cycle). I'll probably throw
symlink/hardlink restrictions stuff from Kees into the next pile, too.
Plus there's a lot of misc patches I hadn't thrown into that one -
it's large enough as it is..."

We are currently using an inferior or equal operator for comparing
the transfer frequency with the clock frequency table. Because of
this, we always end up selecting 20Mhz as a frequency, due to the
inequality transfer hz <= 20 Mhz being always true. Fix this by
reversing the inequality, which is how the comparison should be done.

OMAP watchdog driver is adapted to runtime PM like a general device
driver but it is not appropriate. It is causing couple of functional
issues.
1. On OMAP4 SYSCLK can't be gated, because of issue with WDTIMER2 module,
which constantly stays in "in transition" state. Value of register
CM_WKUP_WDTIMER2_CLKCTRL is always 0x00010000 in this case.
Issue occurs immediately after first idle, when hwmod framework tries
to disable WDTIMER2 functional clock - "wd_timer2_fck". After this
module falls to "in transition" state, and SYSCLK gating is blocked.
2. Due to runtime PM, watchdog timer may be completely disabled.
In current code base watchdog timer is not disabled only because of
issue 1. Otherwise state of WDTIMER2 module will be "Disabled", and there
will be no interrupts from omap_wdt. In other words watchdog will not
work at all.
Watchdong is a special IP and it should not be disabled otherwise
purpose of it itself is defeated. Watchdog functional clock should
never be disabled. This patch updates the runtime PM handling in
driver so that runtime PM is limited only during probe/shutdown
and suspend/resume.
The patch fixes issue 1 and 2

The 57840 boards come in two flavours: 2 x 20G and 4 x 10G.
To better differentiate between the two flavours, a separate device ID
was assigned to each.
The silicon default value is still the currently supported 57840 device ID
(0x168d), and since a user can damage the nvram (e.g., 'ethtool -E')
the driver will still support this device ID to allow the user to amend the
nvram back into a supported configuration.

If platform_get_resource_by_name() fails, driver probe is aborted an
should return an error so the driver is not bound to the device.
However, in the current error path of platform_get_resource_by_name(),
probe returns zero since the return value (ret) is not properly set.
With a zero return value, the driver core assumes probe was successful
and will bind the driver to the device.
Fix this by ensuring that probe returns an error code in this failure
path.

Lots and lots of fixes from Axel and some others here, plus some framework
enhancements which continue the theme of factoring code out of the drivers
and into the core.
- Initial framework support for GPIO controlled enable signals, saving a
bunch of code in drivers.
- Move fixed regulator enable time and voltage mapping table
specifications to data.
- Used some of the recent framework enhancements to make voltage change
notifications more useful, passing the voltage in as an argument to the
notification.
- Fixed the pattern used for finding individual regulators on a device
to not rely on the node name, supporting the use of multiple PMICs of
the same type in the system.
- New drivers for Maxim MAX77686, TI LP872x and LP8788, Samsung S2MPS11,
and Wolfson Arizona microphone supplies and LDOs.

Add a call to mmc_set_signal_voltage() to set signal voltage to 3.3v in
mmc_power_up so that we do not need to touch signal voltage setting in
mmc/sd/sdio init functions and rescan function.
For mmc/sd cards, when doing a suspend/resume cycle, consider the unsafe
resume case, the card will lose its power and when powered on again, we
will set signal voltage to 3.3v in mmc_power_up before its resume function
gets called, which will re-init the card.
And for sdio cards, when doing a suspend/resume cycle, consider the unsafe
resume case, the card will either lose its power or not depending on if it
wants to wakeup the host. If power is not maintained, it is the same case as
mmc/sd cards. If power is maintained, mmc_power_up will not be called and
the card's signal voltage will remain at the last setting.

The Marvell CaFe is now marked as having bad card detection to fix
a problem during system resume.
Now on the OLPC XO-1 we are facing the issue that the card is marked
as logically unremovable (via MMC_UNSAFE_RESUME), which means that
mmc_card_is_removable considers the card non-removable. The existing
code logic decides not to poll for card presence in this case, and
card detection is also disabled because of the quirk being set.
This means that no SD cards are detected when inserted after boot.
Refine the logic to enable card presence polling in the case when
a card is logically unremovable, only avoiding the poll in the case
when the card is physically non-removable (denoted with
MMC_CAP_NONREMOVABLE).

Add a new flag of SDHCI_USING_RETUNING_TIMER to represent if the host
is using a retuning timer for the card inserted.
This flag is set when the host does tuning the first time for the card
and the host's retuning mode is 1. This flag is used afterwards whenever
needs to decide if the host is currently using a retuning timer.
This flag is cleared when the card is removed in sdhci_reinit.
The set/clear of the flag and the start/stop of the retuning timer is
associated with the card's init/remove time, so there is no need to
touch it when the host is to be removed as at that time the card should
have already been removed.

In mmc_read_switch, just do a one time mode 0 switch command to get the
support bits information, no need to do multiple times as the support
bits do not change with different arguments.
And no need to check current limit support bits, as these bits are
fixed according to the signal voltage. If the signal voltage is 1.8V,
the support bits would be 0xf and if the signal voltage is 3.3V, the
support bits would be 0x01. We will check host's ability to set the
current limit.

Some of the host settings are affected by different cards inserted, e.g.
when an UHS-I card is inserted, the SDHCI_NEEDS_RETUING flag might be
set when the tuning timer expired and host's max_blk_count will be
reduced to make sure the data transfer for a command does not exceed 4MiB
to meet the retuning mode 1's requirement.
When the card is removed, we should restore the original setting of the
host since we can't be sure the next card being inserted will still be
an UHS-I card that needs tuning. The original setting include its
max_blk_count and no set of the flag of SDHCI_NEEDS_RETUNING.

For SD hosts using retuning mode 1, when retuning timer expired, it will
need to do retuning in sdhci_request before processing the actual
request. But the retuning command is fixed: cmd19 for SD card and cmd21
for eMMC card, so we can't use the original request's command to do the
tuning.
And since the tuning command depends on the card type attached to the
host, we will need to know the card type to use the correct tuning
command.

At http://dev.laptop.org/ticket/11980 we have determined that the
Marvell CaFe SDHCI controller reports bad card presence during
resume. It reports that no card is present even when it is.
This is a regression -- resume worked back around 2.6.37.
Around 400ms after resuming, a "card inserted" interrupt is
generated, at which point it starts reporting presence.
Work around this hardware oddity by setting the
SDHCI_QUIRK_BROKEN_CARD_DETECTION flag.
