Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Radim Krčmář:
"ARM:
- a fix for a build failure introduced in -rc1 when tracepoints are
enabled on 32-bit ARM.
- disable 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"
