Merge include/asm-ppc/kexec.h and include/asm-ppc64/kexec.h. The only thing that's really changed is that we now allocate crash_notes properly on PPC32. It's address is exported via sysfs, so it's not correct for it to be a pointer. I've also removed some of the "we don't use this" comments, because they're wrong (or perhaps were referring only to arch code). Signed-off-by: Michael Ellerman <michael@ellerman.id.au>
