[PATCH RT 0/2] Linux 3.2.60-rt88-rc1

[PATCH RT 0/2] Linux 3.2.60-rt88-rc1

[Steven Rostedt]

Dear RT Folks,

This is the RT stable review cycle of patch 3.2.60-rt88-rc1.

Please scream at me if I messed something up. Please test the patches too.

The -rc release will be uploaded to kernel.org and will be deleted when
the final release is out. This is just a review release (or release candidate).

The pre-releases will not be pushed to the git repository, only the
final release is.

If all goes well, this patch will be converted to the next main release
on 7/7/2014.

Enjoy,

-- Steve

From: Ben Hutchings <ben@decadent.org.uk>

In an rt-kernel with CONFIG_MISSED_TIMER_OFFSETS_HIST enabled,
__hrtimer_start_range_ns() now crashes, as new_base is not assigned
before it is used.
