- Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if and only
if the incoming events->nmi.pending is non-zero. If the target vCPU is in
the UNITIALIZED state, the spurious request will result in KVM exiting to
userspace, which in turn causes QEMU to constantly acquire and release
QEMU's global mutex, to the point where the BSP is unable to make forward
progress.
- Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl being
incorrectly truncated, and ultimately causes KVM to think a fixed counter
has already been disabled (KVM thinks the old value is '0').
- Fix a stack leak in KVM_GET_MSRS where a failed MSR read from userspace
that is ultimately ignored due to ignore_msrs=true doesn't zero the output
as intended.

KVM x86 fixes for 6.8:
- Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if and only
if the incoming events->nmi.pending is non-zero. If the target vCPU is in
the UNITIALIZED state, the spurious request will result in KVM exiting to
userspace, which in turn causes QEMU to constantly acquire and release
QEMU's global mutex, to the point where the BSP is unable to make forward
progress.
- Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl being
incorrectly truncated, and ultimately causes KVM to think a fixed counter
has already been disabled (KVM thinks the old value is '0').
- Fix a stack leak in KVM_GET_MSRS where a failed MSR read from userspace
that is ultimately ignored due to ignore_msrs=true doesn't zero the output
as intended.
