[patch 0/2] softlockup watchdog improvements
Here's couple of patches to improve the softlockup watchdog.
The first changes the softlockup timer from using jiffies to sched_clock()
as a timebase. Xen and VMI implement sched_clock() as counting unstolen
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
Hi Ingo,
This series of patches implements a number of improvements to the
softlockup watchdog and its users.
They are:
1. Make the watchdog ignore stolen time
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,
