[PATCH 0/3] powerpc: fix preempt_count imbalances in perf and kexec paths

[Aboorva Devarajan]

Hi all,

This patch series fixes some minor preempt_count bookkeeping issues in
arch/powerpc/ found during a preemption leak audit prompted by the
lazy/full preemption model changes. These are get_cpu/put_cpu and
get_cpu_var/put_cpu_var pairing errors that leave preempt_count
incorrectly elevated or underflowed.

Please let me know your comments.

Thanks,
Aboorva
