Linus,
Please pull the latest sched-core-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-for-linus
# HEAD: 096aa33863a5e48de52d2ff30e0801b7487944f4 sched/numa: Decay ->wakee_flips instead of zeroing
The main scheduling related changes in this cycle were:
- various sched/numa updates, for better performance
- tree wide cleanup of open coded nice levels
- nohz fix related to rq->nr_running use
- cpuidle changes and continued consolidation to improve the
kernel/sched/idle.c high level idle scheduling logic. As part of
this effort I pulled cpuidle driver changes from Rafael as well.
- standardized idle polling amongst architectures
- continued work on preparing better power/energy aware scheduling
- sched/rt updates
- misc fixlets and cleanups
Thanks,
Ingo

This introduces this obviously correct warning (on 32 bit x86):
arch/x86/kernel/apm_32.c: In function 'apm_do_idle':
arch/x86/kernel/apm_32.c:844:6: warning: unused variable 'polling' [-Wunused-variable]
int polling;
^
Is the trivial patch to remove 'polling' queued somewhere?

Compile tested. "polling" is unused since commit f80c5b39b80a
("sched/idle, x86: Switch from TS_POLLING to TIF_POLLING_NRFLAG").
Apparently this trivial cleanup isn't yet queued anywhere.
