[PATCH] clean up PPC for private futex changes.

[Steven Munroe]

PPC is broken in mainline due to missing private futex support. The
attached patch attempts to enable PPC for private futexes. I am not sure
if I reverse engineered the i386/x86_64 changes correctly so a close
inspection would be appreciated (especially for lll_futex_wake_unlock!).

With the attached patch powerpc32/powerpc64 makes/make checks cleanly on
a none-private futex eanbled kernel.

Paul what is the status of private futex support powerpc64 kernels?

thanks
