Pull two powerpc fixes from Ben Herrenschmidt:
"Here's a pair of powerpc fixes for 3.15 which are also going to
stable.
One's a fix for building with newer binutils (the problem currently
only affects the BookE kernels but the affected macro might come back
into use on BookS platforms at any time). Unfortunately, the binutils
maintainer did a backward incompatible change to a construct that we
use so we have to add Makefile check.
The other one is a fix for CPUs getting stuck in kexec when running
single threaded. Since we routinely use kexec on power (including in
our newer bootloaders), I deemed that important enough"
* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
powerpc, kexec: Fix "Processor X is stuck" issue during kexec from ST mode
powerpc: Fix 64 bit builds with binutils 2.24
