PATCH 1/1 arm64: Define _TIF_POLLING_NRFLAG

From: Mark Brown <[email protected]>

arm64 defines TIF_POLLING_NRFLAG but not the corresponding shifted version, breaking the build with next-20140509 due to fd99f91aa007b (sched/idle:
Avoid spurious wakeup IPIs) which added a reference to the shifted version which is present on most arches.

Sorry about that,

Should I get it in -tip so borkage and fix come in through the same tree, or what's the preferred routing?

I replied already in another thread. I don't think we need this bit at all.

Whatever it's easier for you.
