Subject[GIT PULL] Please pull powerpc/linux.git powerpc-4.21-1 tag

Hi Linus,

Please pull powerpc updates for 4.21:

The following changes since commit ccda4af0f4b92f7b4c308d3acc262f4a7e3affad:

Linux 4.20-rc2 (2018-11-11 17:12:31 -0600)

are available in the git repository at:

https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git tags/powerpc-4.21-1

for you to fetch changes up to 12526b0d6c580df860b31e59d68e5696e16c6e5b:

Merge branch 'next' of https://git.kernel.org/pub/scm/linux/kernel/git/scottwood/linux into next (2018-12-24 14:14:45 +1100)


There are two conflicts I'm aware of.

The first is in arch/powerpc/mm/fault.c, the resolution is to add the 0xe00 case
to the switch and use the pr_alert() version of the printk.

The other is in arch/powerpc/kernel/iommu.c, where we deleted some code that was
modified in the iommu tree to use a new accessor.

cheers

powerpc updates for 4.21

Notable changes:

- Mitigations for Spectre v2 on some Freescale (NXP) CPUs.

- A large series adding support for pass-through of Nvidia V100 GPUs to guests
on Power9.

- Another large series to enable hardware assistance for TLB table walk on
MPC8xx CPUs.

- Some preparatory changes to our DMA code, to make way for further cleanups
from Christoph.

- Several fixes for our Transactional Memory handling discovered by fuzzing the
signal return path.

- Support for generating our system call table(s) from a text file like other
architectures.

- A fix to our page fault handler so that instead of generating a WARN_ON_ONCE,
user accesses of kernel addresses instead print a ratelimited and
appropriately scary warning.

- A cosmetic change to make our unhandled page fault messages more similar to
other arches and also more compact and informative.

- Freescale updates from Scott:
"Highlights include elimination of legacy clock bindings use from dts
files, an 83xx watchdog handler, fixes to old dts interrupt errors, and
some minor cleanup."

And many clean-ups, reworks and minor fixes etc.
