KVM: x86: prevent uninitialized variable warning in check_svme() (2017-05-19 19:59:28 +0200)

----------------------------------------------------------------
KVM fixes for v4.12-rc2

ARM:
- A fix for a build failure introduced in -rc1 when tracepoints are
enabled on 32-bit ARM.
- Disabling use of stack pointer protection in the hyp code which can
cause panics.
- A handful of VGIC fixes.
- A fix to the init of the redistributors on GICv3 systems that
prevented boot with kvmtool on GICv3 systems introduced in -rc1.
- A number of race conditions fixed in our MMU handling code.
- A fix for the guest being able to program the debug extensions for
the host on the 32-bit side.

PPC:
- Fixes for build failures with PR KVM configurations.
- A fix for a host crash that can occur on POWER9 with radix guests.

x86:
- Fixes for nested PML and nested EPT.
- A fix for crashes caused by reserved bits in SSE MXCSR that could
have been set by userspace.
- An optimization of halt polling that fixes high CPU overhead.
- Fixes for four reports from Dan Carpenter's static checker.
- A protection around code that shouldn't have been preemptible.
- A fix for port IO emulation.
