Merge tag 'powerpc-3.19-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux
Pull powerpc fixes from Michael Ellerman: - Wire up sys_execveat(). Tested on 32 & 64 bit. - Fix for kdump on LE systems with cpus hot unplugged. - Revert Anton's fix for "kernel BUG at kernel/smpboot.c:134!", this broke other platforms, we'll do a proper fix for 3.20. * tag 'powerpc-3.19-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux: Revert "powerpc: Secondary CPUs must set cpu_callin_map after setting active and online" powerpc/kdump: Ignore failure in enabling big endian exception during crash powerpc: Wire up sys_execveat() syscall
