Linus,

test merge showed a conflict in arch/arm64/kvm/inject_fault.c and
arch/arm/kvm/emulate.c that should be handled as in next.
(The desired result is the same as "pull -s recursive -X theirs".)

Also, a simple future merge conflict was reported with the kspp tree,
https://lkml.org/lkml/2017/11/2/27.

The following changes since commit 38c53af853069adf87181684370d7b8866d6387b:

KVM: PPC: Book3S HV: Fix exclusion between HPT resizing and other HPT updates (2017-11-08 15:14:02 +1100)

Merge tag 'kvm-s390-next-4.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux (2017-11-16 14:39:46 +0100)

----------------------------------------------------------------
First batch of KVM changes for 4.15

Common:
- Python 3 support in kvm_stat

- Accounting of slabs to kmemcg

ARM:
- Optimized arch timer handling for KVM/ARM

- Improvements to the VGIC ITS code and introduction of an ITS reset
ioctl

- Unification of the 32-bit fault injection logic

- More exact external abort matching logic

PPC:
- Support for running hashed page table (HPT) MMU mode on a host that
is using the radix MMU mode; single threaded mode on POWER 9 is
added as a pre-requisite

- Resolution of merge conflicts with the last second 4.14 HPT fixes

- Fixes and cleanups

s390:
- Some initial preparation patches for exitless interrupts and crypto

- New capability for AIS migration

- Fixes

x86:
- Improved emulation of LAPIC timer mode changes, MCi_STATUS MSRs, and
after-reset state

- Refined dependencies for VMX features

- Fixes for nested SMI injection

- A lot of cleanups
