kvm: x86: Fix vmwrite to SECONDARY_VM_EXEC_CONTROL (2016-01-12 11:42:16 +0100)

PPC changes will come next week.
----------------------------------------------------------------
* s390: Support for runtime instrumentation within guests,
support of 248 VCPUs.

* ARM: rewrite of the arm64 world switch in C, support for
16-bit VM identifiers. Performance counter virtualization
missed the boat.

* x86: Support for more Hyper-V features (synthetic interrupt
controller), MMU cleanups
