Merge tag 'powerpc-4.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull more powerpc updates from Michael Ellerman:
"Highlights include:
- an update of the disassembly code used by xmon to the latest
versions in binutils. We've received permission from all the
authors of the relevant binutils changes to relicense their changes
to the relevant files from GPLv3 to GPLv2, for inclusion in Linux.
Thanks to Peter Bergner for doing the leg work to get permission
from everyone.
- addition of the "architected" Power9 CPU table entry, allowing us
to boot in Power9 architected mode under a hypervisor.
- updates to the Power9 PMU code.
- implementation of clear_bit_unlock_is_negative_byte() to optimise
unlock_page().
- Freescale updates from Scott: "Highlights include 8xx breakpoints
and perf, t1042rdb display support, and board updates."
Thanks to:
