[PATCH v4 0/5] ppc: Enable full Xen build

[Shawn Anastasio <sanastasio@xxxxxxxxxxxxxxxxxxxxx>]

Hello all,

This patch series performs all of the additions necessary to drop the
build overrides for PPC and enable the full Xen build. Except in cases
where compatibile implementations already exist (e.g. atomic.h and
bitops.h), the newly added definitions are simple, unimplemented stubs
that just call BUG_ON("unimplemented").

Thanks,
Shawn
