Hi Linus,

As I mentioned in the previous pull request, we had some nasty conflicts
with the KVM tree that resulted in us dropping some spectre-related work
shortly before the merge window opened. Now that the KVM tree has been
merged, we've put together an updated version of the patches based on
your merge commit (details in the tag). I appreciate this isn't ideal,
so if you'd rather just see this stuff at -rc1 please let me know and we
can do that instead.

There are also a couple of patches here adding some unused assembler
macros which will be needed by some 4.18 crypto code and we'd like to
head that dependency off early.

Thanks,

Will

  arm64: assembler: add macros to conditionally yield the NEON under PREEMPT 
(2018-04-11 18:50:34 +0100)

----------------------------------------------------------------
Additional arm64 updates for 4.17

A few late updates to address some issues arising from conflicts with
other trees:

- Removal of Qualcomm-specific Spectre-v2 mitigation in favour of the
  generic SMCCC-based firmware call

- Fix EL2 hardening capability checking, which was bodged to reduce
  conflicts with the KVM tree

- Add some currently unused assembler macros for managing SIMD registers
  which will be used by some crypto code in the next merge window
