Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (151 commits) powerpc: Fix usage of 64-bit instruction in 32-bit altivec code MAINTAINERS: Add PowerPC patterns powerpc/pseries: Track previous CPPR values to correctly EOI interrupts powerpc/pseries: Correct pseries/dlpar.c build break without CONFIG_SMP powerpc: Make "intspec" pointers in irq_host->xlate() const powerpc/8xx: DTLB Miss cleanup powerpc/8xx: Remove DIRTY pte handling in DTLB Error. powerpc/8xx: Start using dcbX instructions in various copy routines powerpc/8xx: Restore _PAGE_WRITETHRU powerpc/8xx: Add missing Guarded setting in DTLB Error. powerpc/8xx: Fixup DAR from buggy dcbX instructions. powerpc/8xx: Tag DAR with 0x00f0 to catch buggy instructions. powerpc/8xx: Update TLB asm so it behaves as linux mm expects. powerpc/8xx: Invalidate non present TLBs powerpc/pseries: Serialize cpu hotplug operations during deactivate Vs deallocate pseries/pseries: Add code to online/offline CPUs of a DLPAR node powerpc: stop_this_cpu: remove the cpu from the online map. powerpc/pseries: Add kernel based CPU DLPAR handling sysfs/cpu: Add probe/release files powerpc/pseries: Kernel DLPAR Infrastructure ...
