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
