We need to wait for 1000 ms after Data Link Layer Link Active (DLLLA)
bit reads 1b before sending configuration request. Currently pciehp
does this wait after checking Link Training (LT) bit. But we need it
before checking LT bit because LT is still set even after DLLLA bit is
set on some platforms.

Firmware expects 'max_ssid_length' field in
'struct mwifiex_ie_types_wildcard_ssid_params' to be '0' for
performing SSID specific scan. Currently driver updates it with
an actual SSID length. Hence UUT is not able to find the AP
configured in hidden SSID mode in scan results and association
fails.
max_ssid_length is filled with '0' to fix the issue.

When HW RF kill switch is set to kill the radio, our NIC issues an
interrupt after we stop the APM module. When we unload the module,
the driver disables and cleans the interrupts before stopping the
APM. So we have a real interrupt (inta not zero) pending.
When this interrupts pops up the tasklet has already been killed
and we crash.
Here is a logical description of the flow:
disable and clean interrupts
synchronize interrupts
kill the tasklet
stop the APM <<== creates an RF kill interrupt
free_irq <<== somehow our ISR is called here and we crash
Here is the panic message:

>
> when we have a perfectly good pm_idle hook already in place - so there's
> no excuse for these especially when other platforms are already using
> pm_idle to hook their platform specific idle function into. This is

Aacraid controller can hang on some nodes if kernel uses non-default
(powersave) ASPM policy. Controller hangs shortly after successful load and
hardware detection. Scsi error handler detects this hang and tries to restart
hardware but it does not help.
Initially it was noticed on RHEL6-based openVZ kernel after backporting
aacraid driver from mainline (RHEL6 kernel with original driver works well)
http://bugzilla.openvz.org/show_bug.cgi?id=2043
This issue happens because default ASPM policy was changed in Red Hat
kernels. Therefore guys from Red Hat have noticed this problem long time ago:
on Fedora 12
https://bugzilla.redhat.com/show_bug.cgi?id=540478
on Fedora 14
https://bugzilla.redhat.com/show_bug.cgi?id=679385
In RHEL6 kernel this issue was fixed, ASPM was disabled in aacraid driver. In
kernel changelog I've found that seems it was done by Matthew Garrett: -
[scsi] aacraid: Disable ASPM by default (Matthew Garrett) [599735]
However seems this patch was not submitted to mainline. I've reproduced this
issue on vanilla 3.1.0 kernel booted with "pcie_aspm.policy=powersave" option,
So I believe it makes sense to do it now.

bdi_prune_sb() in bdi_unregister() attempts to removes the bdi links
from all super_blocks and then del_timer_sync() the writeback timer.
However, this can race with __mark_inode_dirty(), leading to
bdi_wakeup_thread_delayed() rearming the writeback timer on the bdi
we're unregistering, after we've called del_timer_sync().
This can end up with the bdi being freed with an active timer inside it,
as in the case of the following dump after the removal of an SD card.
Fix this by redoing the del_timer_sync() in bdi_destory().

during the review of the fix for locks problems in drm_wait_vblank,
a couple of false concerns were raised about how the drm_vblank_get
and drm_vblank_put are used in this function; it turned out that the
code is correct and that it cannot be simplified
add a few comments to explain non-obvious flows in the code,
to prevent "false alarms" in the future

drm_wait_vblank must be DRM_UNLOCKED because otherwise it
will grab the drm_global_mutex and then go to sleep until the vblank
event it is waiting for. That can wreck havoc in the windowing system
because if one process issues this ioctl, it will block all other
processes for the duration of all vblanks between the current and the
one it is waiting for. In some cases it can block the entire windowing
system.
v2: incorporate comments received from Daniel Vetter and
Michel Daenzer.
v3/v4: after a lengty discussion with Daniel Vetter, it was concluded
that the only thing not yet protected with locks and atomic
ops is the write to dev->last_vblank_wait. It's only used in a
debug file in proc, and the current code already employs no
correct locking: the proc file only takes dev->struct_mutex,
whereas drm_wait_vblank implicitly took the drm_global_mutex.
Given all this, it's not worth bothering to try to fix
the locks at this time.

We restore the CRTC, encoder, and connector configurations, but if the
mode set failed, the attached display may have been turned off, so we
need to try set_config again to restore things to the way they were.

slow-work got killed in commit 181a51f6e0. This means that since v2.6.36
there is no Kconfig symbol SLOW_WORK. Apparently selecting that symbol
is a nop. Drop that select.

Nouveau, when configured with debugfs, creates debugfs files for every
channel, so structure holding list of files needs to be protected from
simultaneous changes by multiple threads.
Without this patch it's possible to hit kernel oops in
drm_debugfs_remove_files just by running a couple of xterms with
looped glxinfo.

This was only the case if the GPU reset was triggered from the CS ioctl,
otherwise other processes could happily enter the CS ioctl and wreak havoc
during the GPU reset.
This is a little complicated because the GPU reset can be triggered from the
CS ioctl, in which case we're already holding the mutex, or from other call
paths, in which case we need to lock the mutex. AFAICT the mutex API doesn't
allow recursive locking or finding out the mutex owner, so we need to handle
this with helper functions which allow recursive locking from the same
process.

The following commits break cpuidle on SH-Mobile ARM:
46bcfad cpuidle: Single/Global registration of idle states
e978aa7 cpuidle: Move dev->last_residency update to driver enter routine; remove dev->last_state
This patch remedies these issues by up-porting the SH-Mobile
code to fit with the above introduced framework changes.
It is worth noting that the new code becomes significantly cleaner,
so these framework changes are very welcome. At the same time this
breakage could probably have been avoided by grepping for "last_state"
and "cpuidle_register_driver".

Clean up and fix pwr_nids for 92HD71 / 73 / 83 family codecs; remove
pwr_mapping which was incorrect.
The original pwr_nids support of 92HD83xxx was incorrect and never
actually worked before. Now we should have things working correctly
without having to hack by DID anymore.
It is also not necessary to explicitly turn on all the pins near the
beginning of patch_stac92hd83xxx() now, the pins will go though
initialization properly.
Tested on 92HD66 / 71 / 73 / 75 / 83 / 89 / 91 demo boards.
