Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux
Pull more powerpc updates from Michael Ellerman:
"Here's some more updates for powerpc for 3.18.
They are a bit late I know, though must are actually bug fixes. In my
defence I nearly cut the top of my finger off last weekend in a
gruesome bike maintenance accident, so I spent a good part of the week
waiting around for doctors. True story, I can send photos if you like :)
Probably the most interesting fix is the sys_call_table one, which
enables syscall tracing for powerpc. There's a fix for HMI handling
for old firmware, more endian fixes for firmware interfaces, more EEH
fixes, Anton fixed our routine that gets the current stack pointer,
and a few other misc bits"
