[PATCH] x86: avoid check hlt for newer cpus
Check hlt instruction was targeted for some older CPUs. It is an expensive operation in that it takes 4 ticks to break out the check. We can avoid such check completely for newer x86 cpus ( family > 5). http://lkml.org/lkml/2010/5/7/395 Signed-off-by: Jacob Pan <jacob.jun.pan(a)linux.intel.com> --- arch/x86/ker... 7 May 2010 18:57

[GIT] HID
Linus, please consider pulling from git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid.git for-linus to receive fixes which are destined for 2.6.34 still. Most of them are tiny behavior adjustments/fixes to individual hardware-specific drivers, but the one from Alan Stern is a crucial fix for bug wh... 7 May 2010 17:51

[PATCH 2/8] [nmi watchdog] touch_softlockup cleanups and softlockup_tick removal
Just some code cleanup to make touch_softlockup clearer and remove the softlockup_tick function as it is no longer needed. Also remove the /proc softlockup_thres call as it has been changed to watchdog_thres.

[PATCH 0/8] lockup detector changes
This patch series covers mostly the changes necessary for combining the nmi_watchdog and softlockup code. Also added are the cleanups associated with the change, like removing the old files. The changelogs in each patch are more specific to what the changes are. V2: reworked patch 2 to not change the touch_so... 7 May 2010 17:51

[PATCH 8/8] [watchdog] separate touch_nmi_watchdog code path from touch_watchdog
When I combined the nmi_watchdog (hardlockup) and softlockup code, I also combined the paths the touch_watchdog and touch_nmi_watchdog took. This may not be the best idea as pointed out by Frederic W., that the touch_watchdog case probably should not reset the hardlockup count. Therefore the patch belows falls ba... 7 May 2010 17:51
