Hi Segher,
Looks like the problematic function is dcbz, as there is no segfault
when only that function is reverted to a
pre-6c5875843b87c3adea2beade9d1b8b3d4523900a state.
I was able to expose a singular problematic callsite using the attached
patch (let me know if that is insufficient).
I have attached the disassembly of arch/powerpc/kernel/mem.o with
clear_page (working) and broken_clear_page (broken), along with the side
by side diff. My assembly knowledge is fairly limited as it stands and
it is certainly not up to snuff on PowerPC so I have no idea what I am
looking for. Please let me know if anything immediately looks off or if
there is anything else I can do to help out.
Cheers,
Nathan
