Hi Linus, Please pull the first set of powerpc updates for 4.11.
I've split it in two because I had a last minute query on one of the
commits in my next branch. This pull includes everything up to but not
including that commit. I'll send you a second pull once that's resolved.
The changes to arch/m68k, kernel/kprobes.c and include/linux/cpuidle.h
were all acked.
The KVM changes are also being merged via the KVM tree.
There's a minor conflict in arch/powerpc/Kconfig, where the resolution
is just to drop the HAVE_CC_STACKPROTECTOR line.
cheers

powerpc/mm/radix: Skip ptesync in pte update helpers (2017-02-15 20:02:41
+1100)
----------------------------------------------------------------
powerpc updates for 4.11 part 1.
Highlights include:
- Support for direct mapped LPC on POWER9, giving Linux direct access to
devices that may be on there such as a UART.
- Memory hotplug support for the Power9 Radix MMU.
- Add new AUX vectors describing the processor's cache geometry, to be used by
glibc.
- The ability for a guest to ask the hypervisor to resize the guest's hash
table, and in addition support for doing so automatically when memory is
hotplugged into/out-of the guest. This allows the hash table to be sized
based on the current memory usage of the guest, rather than the maximum
possible memory usage.
- Implementation of optprobes (kprobe optimisation) for powerpc.
In addition there's the topic branch shared with the KVM tree, which includes
support for guests to use the Radix MMU on Power9.
