Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM changes from Paolo Bonzini: "These are the x86, MIPS and s390 changes; PPC and ARM will come in a few days. MIPS and s390 have little going on this release; just bugfixes, some small, some larger. The highlights for x86 are nested VMX improvements (Jan Kiszka), optimizations for old processor (up to Nehalem, by me and Bandan Das), and a lot of x86 emulator bugfixes (Nadav Amit). Stephen Rothwell reported a trivial conflict with the tracing branch" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (104 commits) x86/kvm: Resolve shadow warnings in macro expansion KVM: s390: rework broken SIGP STOP interrupt handling KVM: x86: always exit on EOIs for interrupts listed in the IOAPIC redir table KVM: vmx: remove duplicate vmx_mpx_supported() prototype KVM: s390: Fix memory leak on busy SIGP stop x86/kvm: Resolve shadow warning from min macro kvm: Resolve missing-field-initializers warnings Replace NR_VMX_MSR with its definition KVM: x86: Assertions to check no overrun in MSR lists KVM: x86: set rflags.rf during fault injection KVM: x86: Setting rflags.rf during rep-string emulation KVM: x86: DR6/7.RTM cannot be written KVM: nVMX: clean up nested_release_vmcs12 and code around it KVM: nVMX: fix lifetime issues for vmcs02 KVM: x86: Defining missing x86 vectors KVM: x86: emulator injects #DB when RFLAGS.RF is set KVM: x86: Cleanup of rflags.rf cleaning KVM: x86: Clear rflags.rf on emulated instructions KVM: x86: popf emulation should not change RF KVM: x86: Clearing rflags.rf upon skipped emulated instruction ...
