Hi Linus,

Please pull the second batch of powerpc updates for 3.19:

The following changes since commit 56548fc0e86cb9156af7a7e1f15ba78f251dafaf:

  powerpc/powernv: Return to cpu offline loop when finished in KVM guest (2014-12-08 13:16:31 +1100)

  powerpc/powernv: Ignore smt-enabled on Power8 and later (2014-12-18 19:59:21 +1100)

----------------------------------------------------------------
powerpc updates for 3.19 batch 2

The highlight is the series that reworks the idle management on powernv, which
allows us to use deeper idle states on those machines.

There's the fix from Anton for the "BUG at kernel/smpboot.c:134!" problem.

An i2c driver for powernv. This is acked by Wolfram Sang, and he asked that we
take it through the powerpc tree.

A fix for audit from rgb at Red Hat, acked by Paul Moore who is one of the audit
maintainers.

A patch from Ben to export the symbol map of our OPAL firmware as a sysfs file,
so that tools can use it.

Also some CXL fixes, a couple of powerpc perf fixes, a fix for smt-enabled, and
the patch to add __force to get_user() so we can use bitwise types.
