Re: [PATCH v5 05/15] livepatch/powerpc: add TIF_PATCH_PENDING thread flag

Josh Poimboeuf [off-list ref] writes:

Add the TIF_PATCH_PENDING thread flag to enable the new livepatch
per-task consistency model for powerpc.  The bit getting set indicates
the thread has a pending patch which needs to be applied when the thread
exits the kernel.

The bit is included in the _TIF_USER_WORK_MASK macro so that
do_notify_resume() and klp_update_patch_state() get called when the bit
is set.

The arch changes here seem fine. I haven't tested the whole series
though.
