Subject[GIT PULL] First batch of KVM changes for v4.14
Linus,

there is going to be a simple merge conflict between ea2800ddb20d
("kvm/x86: Avoid clearing the C-bit in rsvd_bits()") and d6321d493319
("KVM: x86: generalize guest_cpuid_has_ helpers"). It should be
resolved as in next and I've also pasted the resolution at the bottom.

Outside of kvm files, there there is an obligatory MAINTAINERS patch and
a VGIF feature flag addition. Topic branch merges in s390 and powerpc
are already in mainline -- would you prefer to see the expected result
after merge instead of what `git request-pull` produces?

Thanks.

----------------------------------------------------------------
First batch of KVM changes for 4.14

Common:
- improve heuristic for boosting preempted spinlocks by ignoring VCPUs
in user mode

ARM:
- fix for decoding external abort types from guests

- added support for migrating the active priority of interrupts when
running a GICv2 guest on a GICv3 host

- minor cleanup

PPC:
- expose storage keys to userspace

- merge powerpc/topic/ppc-kvm branch that contains
find_linux_pte_or_hugepte and POWER9 thread management cleanup

- merge kvm-ppc-fixes with a fix that missed 4.13 because of vacations

- fixes

s390:
- merge of topic branch tlb-flushing from the s390 tree to get the
no-dat base features

- merge of kvm/master to avoid conflicts with additional sthyi fixes

- wire up the no-dat enhancements in KVM

- multiple epoch facility (z14 feature)

- Configuration z/Architecture Mode

- more sthyi fixes

- gdb server range checking fix

- small code cleanups

x86:
- emulate Hyper-V TSC frequency MSRs

- add nested INVPCID

- emulate EPTP switching VMFUNC

- support Virtual GIF

- support 5 level page tables

- speedup nested VM exits by packing byte operations

- speedup MMIO by using hardware provided physical address

- a lot of fixes and cleanups, especially nested
