Update my email address (2017-07-04 14:03:02 +0200)

----------------------------------------------------------------
PPC:
- Better machine check handling for HV KVM
- Ability to support guests with threads=2, 4 or 8 on POWER9
- Fix for a race that could cause delayed recognition of signals
- Fix for a bug where POWER9 guests could sleep with interrupts pending.

ARM:
- VCPU request overhaul
- allow timer and PMU to have their interrupt number selected from userspace
- workaround for Cavium erratum 30115
- handling of memory poisonning
- the usual crop of fixes and cleanups

s390:
- initial machine check forwarding
- migration support for the CMMA page hinting information
- cleanups and fixes

x86:
- nested VMX bugfixes and improvements
- more reliable NMI window detection on AMD
- APIC timer optimizations

Generic:
- VCPU request overhaul + documentation of common code patterns
- kvm_stat improvements

There is a small conflict in arch/s390 due to an arch-wide field rename.
