Currently, when FIFO_ERR happens, we stop the dma, wait for it to become
idle and then reset the whole MAC_RX logic (and after that we must re-set
multicast addresses and also re-enable MAC_RX when we're finally ready to
accept new packets). This leads to CRC errors on high number of incoming
packets and is not needed according to the datasheet.
This patch fixes it by the following steps:
1) remove this reset in pch_gbe_stop_receive(), which causes some functions
to not be used anywhere
2) remove already unused functions pch_gbe_wait_clr_bit_irq() and
pch_gbe_mac_reset_rx() to correctly build
3) move pch_gbe_enable_mac_rx() out of pch_gbe_start_receive() to
pch_gbe_up() where it's only needed after we've removed the MAC_RX reset
4) rename pch_gbe_start/stop_receive() to pch_gbe_enable/disable_dma_rx()
to more precisely reflect what the functions are now doing.
After these changes we already don't see the CRC errors and gain some
increase in RX processing speed.

If we were in RX_FIFO_ERR state and entered pch_gbe_napi_poll(), we'll
anyway clean some rx space and thus can continue to receive more packets.
Currently, we re-set the RX_FIFO_ERR in situations when we've exhausted our
budget for RX cleaning or cleaned some TX packets. Removing it gives us
+20%-40% speed increase and a lot less of RX_FIFO_ERRors reported.

In theory, that function could release the lru lock between
checking for bo on ddestroy list and a successful reserve if the bo
was already reserved, and the function was called with waiting reserves
allowed.
However, all current reservers of a bo on the ddestroy list would
atomically take the bo off the list after a successful reserve so this
race should not have been hit, so no need to backport for stable.
This patch also fixes a case found by Maarten Lankhorst where
ttm_mem_evict_first called with no_wait_gpu would incorrectly

also sits on the ddestroy list.

Memory is allocated with kzalloc() and assigned to

call to 'find_first_zero_bit()', if that results in a value greater
than ACPI_MAX_PHYSICAL_NODE we'll end up jumping to the 'err:' label
and there leave the function and let 'physical_node' go out of scope
and leak the memory we allocated.
This patch fixes the leak by simply freeing the unused/unneeded memory
pointed to by 'physical_node' just before we jump to 'err:'.

Change 130f315a (staging: zram: remove special handle of uncompressed page)
introduced a bug in the handling of incompressible pages which resulted in
memory allocation failure for such pages.
When a page expands on compression, say from 4K to 4K+30, we were trying to
do zsmalloc(pool, 4K+30). However, the maximum size which zsmalloc can
allocate is PAGE_SIZE (for obvious reasons), so such allocation requests
always return failure (0).
For a page that has compressed size larger than the original size (this may
happen with already compressed or random data), there is no point storing
the compressed version as that would take more space and would also require
time for decompression when needed again. So, the fix is to store any page,
whose compressed size exceeds a threshold (max_zpage_size), as-it-is i.e.
without compression. Memory required for storing this uncompressed page can
then be requested from zsmalloc which supports PAGE_SIZE sized allocations.
Lastly, the fix checks that we do not attempt to "decompress" the page which
we stored in the uncompressed form -- we just memcpy() out such pages.

`pc236_detach()` is called by the comedi core if it attempted to attach

the comedi device private data pointer (`devpriv`) is non-null. This

Fix it by checking `dev->iobase` is non-zero before calling

saved and the hardware registers can be accessed. It also implies the
comedi device private data pointer is valid, so there is no need to

their respective structures representing input devices.
Unfortunately character device structure may outlive the parent
structure unless we do not set it up as parent of character device so
that it will stay pinned until character device is freed.
Also, now that parent structure is pinned while character device exists
we do not need to pin and unpin it every time user opens or closes it.

It's questionable use case, but weston/wayland already relies on this

====================
This is a batch of fixes intended for the 3.7 stream.
Dan Carpenter brings a fix for a simple signedness bug that could
prevent the proper termination of a loop.
Felix Fietkau found a few more places that need to use
ieee80211_free_txskb for properly releasing SKBs used by mac80211.
Franky Lin offers a pair of brcmfmac fixes, both fixing simple state
reporting errors.
Hante Meuleman corrects an error reporting case that wasn't handling
all types of errors properly.
Johan Hedberg offers a fix for an issue discovered at the Bluetooth
UnPlug Fest. Gustavo says "the patch fixes a failure to pair with
devices that support the LE Secure Connections feature."
Johannes Berg sends an iwlwifi fix to handle a message type that
is too large for the normal command mechanism. He also provides a
mac80211 fix to use HT20 channels when HT40 channels are not permitted.
Jouni Malinen offers a mac80211 fix for a masking error that was
incorrectly marking some frames.
Piotr Haber provides a fix to make sure bcma devices are unregistered
properly.
Stanislav Yakovlev gives us a fix for a panic in the ipw2200 driver.
Stanislaw Gruszka sends a pair of fixes: one prevents a mismatch on
connection states between cfg80211 and mac80211; the other prevents
some frame corruption related to handling encryption.

The big thing is the disabling of the hsw support by default, cc: stable.
We've aimed for basic hsw support in 3.6, but due to a few bad
happenstances we've screwed up and only 3.8 will have better modeset
support than vesa. To avoid yet another round of fallout from such a
gaffle on for the next platform we've added a module option to disable
early hw support by default. That should also give us more flexibility in
bring-up.
Otherwise just small fixes:
- 3 fixes from Egbert for sdvo corner cases
- invert-brightness quirk entry from Egbert
- revert a dp link training change, it regresses some setups
- and shut up a spurious WARN in our gem fault handler.

because we really don't live in caves using stone-age tools any more,

declarations.
So if a function doesn't take arguments, we tell the compiler so

* Some of the acceleration scales are either completely wrong or have the

* Some of the angular velocity scale are either completely wrong or have

This patch fixes these issues. For consistency it also converts scales which are
correct to use the IIO_G_TO_M_S_2 and IIO_DEGREE_TO_RAD macro. This makes it
much easier to compare it to the value given in the datasheet.

Pull media fixes from Mauro Carvalho Chehab:
"Media fixes for:
- one Kconfig fix patch;
- one patch fixing DocBook breakage due to the drivers/media UAPI
changes;
- the remaining UAPI media changes (DVB API).
I'm aware that is is a little late for the UAPI renames for the DVB
API, but IMHO, it is better to merge it for 3.7, due to two reasons:
1) There is a major rename at 3.7 (not only uapi changes, but also
the entire media drivers were reorganized on 3.7, in order to
simplify the Kconfig logic, and easy drivers selection, especially
for hybrid devices). By confining all those renames there at 3.7
it will cause all the harm at for media developers on just one
shot. Stable backports upstream and at distros will likely
welcome it as well, as they won't need to check what changed on
3.7 and what was postponed for on 3.8.
2) The V4L2 DocBook Makefile creates a cross-reference between the
media API headers and the specs. This helps us _a_lot_ to be sure
that all API improvements are properly documented. Every time a
header changes from one place to another, DocBook/media/Makefile
needs to be patched. Currently, the DocBook breakage patch
depends on the DVB UAPI."

A client re-register event invokes cleanup of all MCGs. This is
required to protect against misbehaved guests leading to corruption of
join/leave database. However, since cleaning up the MCGs is a heavy
operation, it is pushed to a work queue for further processing.
Client re-register is also propagated to ULPs (e.g IPoIB).
However, since the cleanup is performed in a workqueue, the ULP could
leave and re-join groups before the cleanup occurs. In this case,
when the cleanup takes place, it prunes the (newly-joined) MCGs and
the ULP is left without actual MCGs while believing it joined them.
Fix this by setting the flushing flag before invoking the cleanup task
and clearing it after flushing is complete.

In the MAD paravirtualization code, one of the checks performed when
forwarding QP1 (GSI) packets from wire to slave was a P_Key check: the
P_Key received in the MAD must be present in the guest's paravirtualized
P_Key table, and at least one of the (packet P_Key, guest P_Key) must
be a full-membership P_Key.
However, if everyone involved has only limited membership in the
default P_Key, then packets sent by full-member remote hosts arrive at
the PPF but are not passed on to the VFs with the current P_Key1 check.
Fix this as follows:
1. Don't care if P_Key received over wire is full or not. If it
successfully passed HW checks on the real QP1, then simply pass it
to guest regardless of whether the guest has full or limited
membership in its P_Key table.
2. If the guest (including paravirtualized master) has both full and
limited P_Key forms in its table, preferentially pass the
paravirtualized P_Key index of the full P_Key form in the tunnel
header.
3. In the multicast join flow (mlx4/mcg.c), use the index for the
default P_Key (wherever it is located) in replies generated from
within the mcg module (previously, P_Key index 0 was used in all
cases).

Here's the first set of fixes for v3.7-rc cycle.
DesignWare Core USB3 Driver (dwc3) got two fixes. The first one fixes a long
standing bug which would keep endpoint with BUSY flag set forever if we cancel
a transfer which has already been started by the controller. The second fix
will just switch PHYs back off when DWC3 driver is removed.
MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when
removing a device. For some reason that particular device can fall into a
situation where you have both Disconnect and Endpoint IRQs happen
simultaneously (have both bits set in IRQ_STATUS register) and, because
Disconnect Interrupt is handled before Endpoint Interrupts, we would try to
transfer data over a disconnected device, thus generating a kernel oops.
Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on
the pipe iterator implementation and b) fixing Interrupt Status Clear procedure
in order to properly clear a single Interrupt event without clearing (and
masking) other events we didn't handle yet.

This option is a merge of both analog TV and DVB CUSTOMISE.
At the merge, the dependencies were not done right: the menu
currently appears only for analog TV. It should also be opened

to make it generic enough to open for all media devices with

There is a subtle difference between dma_transfer_direction and
dma_data_direction: the former is used by the dmaengine framework,
while the latter is used by the dma-mapping API. Although the
purpose is comparable, the actual values are different and must
not be mixed. In this case, the driver just wants to use
dma_transfer_direction.

The recovery thread, when failing, tears down the respective interface. To do
so, it needs to obtain the rtnl lock first, as the interface configuration is
changed.
If another process tries to modify an interface setting at the same time, that
process can obtain the rtnl lock first, but the respective callback in the qeth
driver will block until recovery has completed - which cannot happen since the
calling process already obtained it.
In one particular case, the bonding driver acquired the rtnl lock to modify the
card's MAC address, while the recovery failed at the same time due to the card
being removed. Hence qeth_l2_set_mac_address (implicitly holding the rtnl lock)
was waiting on qeth_l2_recover, which deadlocked when waiting on the rtnl lock.
This patch uses rtnl_trylock instead of rtnl_lock in the recovery thread. If the
lock cannot be obtained, the interface will be left up, but the card state
remains in CARD_STATE_RECOVER, which will prevent any further activities on the
card.

This reverts commit 2477367083.
If (for whatever reason) the DP sink device never asks for the maximal
voltage level, we never don't hit the check that should bail us out
after 5 retries of the same voltage. Which leads to an endless loop in
the DP link training code, which hangs the driver.
Now some more DP link training experiments on eDP panels seem to
indicate that our training algorithm isn't robust enough anyway and
needs more work. Hence for 3.7-fixes, let's just revert the regressing
commit instead of trying to apply more duct-tape.

For TV and LVDS encoders intel_sdvo_set_input_timings_for_mode()
is called to pass a mode to the sdvo chip and retrieve a dtd
containing information needed to calculate the adjusted_mode which
is done by intel_sdvo_get_dtd_from_mode().
To set this adjusted_mode as input mode for the sdvo chip, a dtd is
recalculated using intel_sdvo_get_mode_from_dtd(). During this round
trip the sdvo_flags contained in the dtd obtained from the hardware
are lost.
Since these flags cannot be ignored in all cases this patch preserves
and restores them.

There the DPLL multiplier is adjusted so that the SDVO gets a sufficient

When cloning a CRTC between an SDVO driven encoder and the standard
DAC the DAC setup code reseted the multiplier value to 1 thus undoing
the correct setup. There is no need to touch the multiplier in the DAC
setup code: the correct value (i.e. 1 in case no SDVO encoder is used)

point calling it otherwise.

With the introduction of fan management modes, fan may not be drivable.
We should allow reclocking nonetheless.
This return was stupid to begin with since it may have left the card
in an intermediate state (clocks corresponding to a perflvl and voltage
corresponding to another one). The reclocking code will need to be
rewritten in a near-future in order to provide a better error handling.

Commit 0236141837 ("thermal: add generic cpufreq cooling
implementation") requires cpufreq_frequency_get_table(), but that
function is only defined for CONFIG_CPU_FREQ_TABLE resulting in the
following build error:
drivers/built-in.o: In function `cpufreq_get_max_state':
drivers/thermal/cpu_cooling.c:259: undefined reference to `cpufreq_frequency_get_table'
drivers/built-in.o: In function `get_cpu_frequency':
drivers/thermal/cpu_cooling.c:129: undefined reference to `cpufreq_frequency_get_table'
Fix it by selecting CONFIG_CPU_FREQ_TABLE for such a configuration.
It turns out CONFIG_EXYNOS_THERMAL also needs CONFIG_CPU_FREQ_TABLE, so
select it there as well.

The problem here is that we loop until "remained_buf_len" is less than
zero, but since it is unsigned, it never is.
"remained_buf_len" has to be large enough to hold the value from
"mgmt_ie_buf_len". That variable is type u32, but it only holds small
values so I have changed to both variables to int.
Also I removed the bogus initialization from "mgmt_ie_buf_len" so that
GCC can detect if it is used unitialized. I moved the declaration of
"remained_buf_len" closer to where it is used so it's easier to read.

radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[]
to destroy each of them.
radeon_ext_tmds_enc_destroy() however also has code to destroy it's
associated I2C bus rec which has been obtained by radeon_i2c_lookup()
and is therefore also in the i2c_bus[] list.
This causes a double free resulting in a kernel panic when unloading
the radeon driver.
Removing destroy code from radeon_ext_tmds_enc_destroy() fixes this
problem.
