-Tejun Heo has a simple workqueue/powernow-k8 fix for -rc6:
This is the fix for the bug where cpufreq/powernow-k8 was tripping
BUG_ON() in try_to_wake_up_local() by migrating workqueue worker to a
different CPU.https://bugzilla.kernel.org/show_bug.cgi?id=47301
As discussed, the fix is now two parts – one to reimplement
work_on_cpu() so that it doesn’t create a new kthread each time and
the actual fix which makes powernow-k8 use work_on_cpu() instead of
performing manual migration.While pretty late in the merge cycle, both changes are on the safer
side. Jiri and I verified two existing users of work_on_cpu() and
Duncan confirmed that the powernow-k8 fix survived about 18 hours of
testing.
-Ben Myers requests a pull for a XFS update for -rc7, Henrik Rydberg
has input and HID updates for 3.7, and Ben Hutchings announces the
release of 3.2.30.
