Recent versions of udev cause synchronous firmware loading from the
probe routine to fail because the request to user space times out.
The original fix for b43legacy (commit a3ea2c7) moved the firmware
load from the probe routine to a work queue, but it still used synchronous
firmware loading. This method is OK when b43legacy is built as a module;
however, it fails when the driver is compiled into the kernel.
This version changes the code to load the initial firmware file
using request_firmware_nowait(). A completion event is used to
hold the work queue until that file is available. The remaining
firmware files are read synchronously.

This adds support for bcma wifi core revision 17 which is found on
BCM4716/4717/4718 SoCs. The firmware version 610.812 for brcmsmac found
in linux-firmware does not support these cores, but a firmware
generated with b43-fwcutter from the proprietary broadcom wireless
driver works with these chips. This wifi core contains a revision 5
N-PHY and a revision 7 radio of type 0x2056.

This reverts commit f74b9d365ddd33a375802b064f96a5d0e99af7c0.
Turns out reverting commit a240dc7b3c7463bd60cf0a9b2a90f52f78aae0fd
"ath9k_hw: Updated AR9003 tx gain table for 5GHz" was not enough to
bring the tx power back to normal levels on devices like the
Buffalo WZR-HP-G450H, this one needs to be reverted as well.
This revert improves tx power by ~10 db on that device

mmc: sdhci-acpi: enable runtime-pm for device HID INT33C6
|
|
sdhci-acpi supports ACPI devices which have compatibility ID
PNP0D40, however it is not possible to know if those devices
will all work correctly with runtime-pm, so that must be configured
per hardware ID.
For INT33C6, several related quirks, capabilities and flags are set:
MMC_CAP_NONREMOVABLE
The SDIO card will never be removable
SDHCI_ACPI_RUNTIME_PM
Enable runtime-pm of the host controller
MMC_CAP_POWER_OFF_CARD
Enable runtime-pm of the SDIO card
MMC_PM_KEEP_POWER
SDIO card has the capability to remain powered up
during system suspend
SDHCI_QUIRK2_HOST_OFF_CARD_ON
Always do a full reset during system resume
because the card may be already initialized having
not been powered off.
Wake-ups from the INT33C6 host controller are not supported, so the
following capability must *not* be set:
MMC_PM_WAKE_SDIO_IRQ
Enable wake on card interrupt

This reverts commits a50915394f1fc02c2861d3b7ce7014788aa5066e and
d7c3b937bdf45f0b844400b7bf6fd3ed50bac604.
This is a revert of a revert of a revert. In addition, it reverts the
even older i915 change to stop using the __GFP_NO_KSWAPD flag due to the
original commits in linux-next.
It turns out that the original patch really was bogus, and that the
original revert was the correct thing to do after all. We thought we
had fixed the problem, and then reverted the revert, but the problem
really is fundamental: waking up kswapd simply isn't the right thing to
do, and direct reclaim sometimes simply _is_ the right thing to do.
When certain allocations fail, we simply should try some direct reclaim,
and if that fails, fail the allocation. That's the right thing to do
for THP allocations, which can easily fail, and the GPU allocations want
to do that too.
So starting kswapd is sometimes simply wrong, and removing the flag that
said "don't start kswapd" was a mistake. Let's hope we never revisit
this mistake again - and certainly not this many times ;)

ip_check_defrag() might be called from af_packet within the
RX path where shared SKBs are used, so it must not modify
the input SKB before it has unshared it for defragmentation.
Use skb_copy_bits() to get the IP header and only pull in
everything later.
The same is true for the other caller in macvlan as it is
called from dev->rx_handler which can also get a shared SKB.

deferred or contended"
This reverts commit 782fd30406ecb9d9b082816abe0c6008fc72a7b0.
We are going to reinstate the __GFP_NO_KSWAPD flag that has been
removed, the removal reverted, and then removed again. Making this
commit a pointless fixup for a problem that was caused by the removal of
__GFP_NO_KSWAPD flag.
The thing is, we really don't want to wake up kswapd for THP allocations
(because they fail quite commonly under any kind of memory pressure,
including when there is tons of memory free), and these patches were
just trying to fix up the underlying bug: the original removal of
__GFP_NO_KSWAPD in commit c654345924f7 ("mm: remove __GFP_NO_KSWAPD")
was simply bogus.

Avoid doing a linear scan of the entire register map for each read() of
the debugfs register dump by recording the offsets where valid registers
exist when we first read the registers file. This assumes the set of
valid registers never changes, if this is not the case invalidation of
the cache will be required.
This could be further improved for large blocks of contiguous registers
by calculating the register we will read from within the block - currently
we do a linear scan of the block. An rbtree may also be worthwhile.

We have two separate, exclusive, users of omapdss: 1) omapfb + omap_vout and 2)
omapdrm. Because omapfb and omap_vout are independent drivers, we've built
layers in omapdss to manage the two simultaneous callers. These layers are not
needed for omapdrm, as omapdrm is the sole user of omapdss, and these layers in
fact only create trouble for omapdrm.
The simple option to improve omapdrm situation would be to copy the omapdss
code for omapdrm. We are trying to avoid this, as omapdss and the panel drivers
are quite a lot of code together, and most of the code would be used without
change.
Thus this series helps the situation by moving the omapdss code required by
omapfb + omap_vout to separate files, creating a distinct layer used only by
omapfb + omap_vout. We call this layer "compat layer". This compat layer then
uses the core omapdss driver to operate the hardware. omapdrm will use the core
omapdss directly, without any layers in between.
After this series, omapfb, omap_vout and omapdrm can all be compiled at the
same time. Obviously omapdrm and omapfb+omap_vout cannot be run at the same
time (the first one to start will "win"), so compiling them at the same time is
only sensible as modules for testing purposes. Normal users should only compile
one of those.
This series does not make omapdrm use the core omapdss API, that will happen in
a separate series for omapdrm.
