[patch 0/2] softlockup watchdog improvements
Here's couple of patches to improve the softlockup watchdog.

time, so time stolen by the hypervisor won't cause the watchdog to bite.
The second adds per-cpu enable flags for the watchdog timer. This allows
the timer to be disabled when the

[patch 0/4] Revised softlockup watchdog improvement patches

When running under a hypervisor, the kernel may lose an arbitrary amount
of time as "stolen time". This may cause the softlockup watchdog to
trigger spruiously. Xen and VMI implement sched_clock() as measuring
unstolen time,
