[PATCH] powerpc TLF_RESTORE_SIGMASK

Mine did lots of stuff fine.

I had only tested with Linus's tree plus the small handful of post-2.6.25
cleanup patches I've posted in the last few weeks.  To be precise it was
9597362d354f8655ece324b01d0c640a0e99c077 plus several of my cleanup patches
(that are probably all in -mm, but I'm not sure off hand).

I'd rebased my tree today to 783e391b7b5b273cd20856d8f6f4878da8ec31b3
anyway.  I just tried the new kernel with the sigmask cleanups and only 
a few other patches, and have no problems.

The details of your crash make it look pretty unrelated to this code.
Off hand I would guess that it's some other bug from other -mm patches
that just happens only to bite you on powerpc.  If the crash is not
intermittent and you bisected it to this one change, then I am at a
loss to see what might be happening.  I'd have to leave it to Paul et
al to figure out if there is some strange powerpc juju going on.


Thanks,
Roland
