Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Paolo Bonzini:
"KVM/ARM fixes:
- Fix per-vcpu vgic bitmap allocation
- Do not give copy random memory on MMIO read
- Fix GICv3 APR register restore order
KVM/x86 fixes:
- Fix ubsan warning
- Fix hardware breakpoints in a guest vs. preempt notifiers
- Fix Hurd
Generic:
- use __GFP_NOWARN together with GFP_NOWAIT"
