Re: [PATCH v2] powerpc/powernv: Fix race in updating core_idle_state

core_idle_state is maintained for each core. It uses 0-7 bits to track
whether a thread in the core has entered fastsleep or winkle. 8th bit is
used as a lock bit.

This patch fixes the above race by looping on the lock bit even while
entering the idle states.

The sha is wrong, it should be 77b54e9f213f.

Also please don't wrap the description.

I recommend creating an alias or script that does:

$ git log --pretty=fixes -n 1 $commit | xclip


I've fixed it up, no need to resend.

cheers
