drm: do not sleep on vblank while holding a mutex
drm_wait_vblank must be DRM_UNLOCKED because otherwise it

that the only thing not yet protected with locks and atomic

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.

This was only the case if the GPU reset was triggered from the CS ioctl,

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

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

We disabled the check of NO_PRESENCE bit of the default pin-config

However, this would still give many regressions on machines with broken
BIOS. They set this bit wrongly even on active pins.
A workaround is to check whether all pins contain this bit. As far as
I've checked, broken BIOSen set this bit on all pins, no matter whether
active or not. In such a case, the driver should ignore this bit check.

ALSA: usb-audio - Fix the missing volume quirks at delayed init
In the recent usb-audio driver, the initialization of volume ranges
may be delayed when the device doesn't respond well at the probing time.
But the volume quirks for certain devices are applied only in
mixer_ctl_feature_info() thus only at the very first probe and will be
missing when the volume range is initialized later.
This patch moves the volume quirk code to be always called from the
volume-range extraction (get_min_max()), so that the quirks are properly
applied in the later init time.
The log item ops aren't nessecarily the biggest exploit vector, but marking

Fixes a possible memory corruption when the link is larger than

Updated to address concerns raised by Ben Hutchings about the loose
attention paid to 32- vs 64-bit values, and the lack of handling a
potentially negative pathlen value:
- Changed type of "pathlen" to be xfs_fsize_t, to match that of
ip->i_d.di_size
- Added checking for a negative pathlen to the too-long pathlen
test, and generalized the message that gets reported in that case
to reflect the change
As a result, if a negative pathlen were encountered, this function
would return EFSCORRUPTED (and would fail an assertion for a debug
build)--just as would a too-long pathlen.

Mountpoint crossing is similar to following procfs symlinks - we do

PM / devfreq: fix private_data
The "private_date" field in struct devfreq_dev_status almost certainly
wants to be "private_data"; since there are no in-tree users of this
functionality, now seems like an easy time to make the fix.

Since commit 4a31a334, the name of this misc device is not initialized,
which leads to a funny device named /dev/(null) being created and
/proc/misc containing an entry with just a number but no name. The latter
leads to complaints by cryptsetup, which caused me to investigate this
matter.

forcedeth: Improve stats counters
Rx byte count was off; instead use the hardware's count. Tx packet
count was counting pre-TSO packets; instead count on-the-wire packets.
Report hardware dropped frame count as rx_fifo_errors.
- The count of transmitted packets reported by the forcedeth driver
reports pre-TSO (TCP Segmentation Offload) packet counts and not the
count of the number of packets sent on the wire. This change fixes
the forcedeth driver to report the correct count. Fixed the code by
copying the count stored in the NIC H/W to the value reported by the
driver.
- Count rx_drop_frame errors as rx_fifo_errors:
We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
for too long. Normally, rx_fifo_errors would be counted in this case.
The rx_drop_frame error count is private to forcedeth and is not
reported by ifconfig or sysfs. The rx_fifo_errors count is currently
unused in the forcedeth driver. It is reported by ifconfig as overruns.
This change reports rx_drop_frame errors as rx_fifo_errors.
