Merge branch 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull more powerpc updates from Ben Herrenschmidt: "Here are a few more powerpc things for you. So you'll find here the conversion of the two new firmware sysfs interfaces to the new API for self-removing files that Greg and Tejun introduced, so they can finally remove the old one. I'm also reverting the hwmon driver for powernv. I shouldn't have merged it, I got a bit carried away here. I hadn't realized it was never CCed to the relevant maintainer(s) and list(s), and happens to have some issues so I'm taking it out and it will come back via the proper channels. The rest is a bunch of LE fixes (argh, some of the new stuff was broken on LE, I really need to start testing LE myself !) and various random fixes here and there. Finally one bit that's not strictly a fix, which is the HVC OPAL change to "kick" the HVC thread when the firmware tells us there is new incoming data. I don't feel like waiting for this one, it's simple enough, and it makes a big difference in console responsiveness which is good for my nerves" * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (26 commits) powerpc/powernv Adapt opal-elog and opal-dump to new sysfs_remove_file_self Revert "powerpc/powernv: hwmon driver for power values, fan rpm and temperature" power, sched: stop updating inside arch_update_cpu_topology() when nothing to be update powerpc/le: Avoid creatng R_PPC64_TOCSAVE relocations for modules. arch/powerpc: Use RCU_INIT_POINTER(x, NULL) in platforms/cell/spu_syscalls.c powerpc/opal: Add missing include powerpc: Convert last uses of __FUNCTION__ to __func__ powerpc: Add lq/stq emulation powerpc/powernv: Add invalid OPAL call powerpc/powernv: Add OPAL message log interface powerpc/book3s: Fix mc_recoverable_range buffer overrun issue. powerpc: Remove dead code in sycall entry powerpc: Use of_node_init() for the fakenode in msi_bitmap.c powerpc/mm: NUMA pte should be handled via slow path in get_user_pages_fast() powerpc/powernv: Fix endian issues with sensor code powerpc/powernv: Fix endian issues with OPAL async code tty/hvc_opal: Kick the HVC thread on OPAL console events powerpc/powernv: Add opal_notifier_unregister() and export to modules powerpc/ppc64: Do not turn AIL (reloc-on interrupts) too early powerpc/ppc64: Gracefully handle early interrupts ...
