mm: Fix fixup_user_fault() for MMU=n

2011-08-16T01:31:43+00:00

commit 5c723ba5b7886909b2e430f2eae454c33f7fe5c6 upstream.

In commit 2efaca927f5c ("mm/futex: fix futex writes on archs with SW
tracking of dirty & young") we forgot about MMU=n.  This patch fixes
that.

ath9k_hw: Fix incorrect Tx control power in AR9003 template

2011-08-16T01:31:43+00:00

commit 15052f81d255eac44e745bc630b36aa86779ad9d upstream.

CTL power data incorrect in ctlPowerData_2G field of ar9300_eeprom.
Setting incorrect CTL power in calibration is causing lower tx power.
Tx power was reported as 3dBm while operating in channel 6 HT40+/
in channel 11 HT40- due to CTL powers in the calibration is set to
zero.

dp83640: increase receive time stamp buffer size

2011-08-16T01:31:42+00:00

commit 8028837d71ba9904b17281b40f94b93e947fbe38 upstream.

The dp83640 buffers receive time stamps from special PHY status frames,
matching them to received PTP packets in a work queue. Because the timeout
for orphaned time stamps is so long and the buffer is so small, the driver
can drop time stamps under moderate PTP traffic.

This commit fixes the issue by decreasing the timeout to (at least) one
timer tick and increasing the buffer size.

gianfar: fix fiper alignment after resetting the time

2011-08-16T01:31:42+00:00

commit cbc056602c7c63620c86904c431ff6b61e029dcc upstream.

After resetting the time, the PPS signals on the FIPER output channels
are incorrectly offset from the clock time, as can be readily verified
by a looping back the FIPER to the external time stamp input.

Despite its name, setting the "Fiper Realignment Disable" bit seems to
fix the problem, at least on the P2020.

Also, following the example code from the Freescale BSP, it is not really
necessary to disable and re-enable the timer in order to reprogram the
FIPER. (The documentation is rather unclear on this point. It seems that
writing to the alarm register also disables the FIPER.)

ext4: Properly count journal credits for long symlinks

2011-08-16T01:31:42+00:00

commit 8c20871998c082f6fbc963f1449a5ba5140ee39a upstream.

Commit df5e6223407e ("ext4: fix deadlock in ext4_symlink() in ENOSPC
conditions") recalculated the number of credits needed for a long
symlink, in the process of splitting it into two transactions.  However,
the first credit calculation under-counted because if selinux is
enabled, credits are needed to create the selinux xattr as well.

Overrunning the reservation will result in an OOPS in
jbd2_journal_dirty_metadata() due to this assert:

  J_ASSERT_JH(jh, handle->h_buffer_credits > 0);

Fix this by increasing the reservation size.
