Source: linux-2.6
Version: 2.6.32-40
Severity: important

cfq-iosched: fix cfq_cic_link() race confition

Fixes race condition leading to block I/O stall; presumably
exploitable as denial-of-service.

Fixes potential deadlock when using this SCSI driver.

MXC PWM: should active during DOZE/WAIT/DBG mode
ARM:imx:fix pwm period value
ARM: 7220/1: mmc: mmci: Fixup error handling for dma

These have no effect on Debian configurations.

vfs: __read_cache_page should use gfp argument rather than GFP_KERNEL

Fixes potential deadlock when using JFS.

watchdog: hpwdt: Changes to handle NX secure bit in 32bit path

Fixes crash on some systems when using this driver.

hung_task: fix false positive during vfork

Fixes incorrect warnings that a task suspended during vfork() has

ath9k: Fix kernel panic in AR2427 in AP mode

That seems clear enough.
