Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull KVM fixes from Radim Krčmář:
"ARM updates from Marc Zyngier:
- vgic updates:
- Honour disabling the ITS
- Don't deadlock when deactivating own interrupts via MMIO
- Correctly expose the lact of IRQ/FIQ bypass on GICv3
- I/O virtualization:
- Make KVM_CAP_NR_MEMSLOTS big enough for large guests with many
PCIe devices
- General bug fixes:
- Gracefully handle exception generated with syndroms that the host
doesn't understand
- Properly invalidate TLBs on VHE systems
x86:
- improvements in emulation of VMCLEAR, VMX MSR bitmaps, and VCPU
reset
