The warnings in the assembler file have been fixed with commit 8a583c0a8d31
("powerpc: Fix invalid use of register expressions"). It is not marked
for stable, and does not cause actual failures, so I would not bother
applying it.

Most of the "may be used uninitialized" warnings are still reported in
ToT.

You missed this one in v4.9.y:

arch/powerpc/kernel/fadump.c: In function 'free_crash_memory_ranges':
/opt/buildbot/slave/stable-queue-4.9/build/arch/powerpc/kernel/fadump.c:738:2: error: implicit declaration of function 'kfree'

Other kernels build fine so far. Builds are still ongoing, but the ppc problems
are fixed in those.
