Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm fixes from Paolo Bonzini:
"ARM:
- selftest fix
- force PTE mapping on device pages provided via VFIO
- fix detection of cacheable mapping at S2
- fallback to PMD/PTE mappings for composite huge pages
- fix accounting of Stage-2 PGD allocation
- fix AArch32 handling of some of the debug registers
- simplify host HYP entry
- fix stray pointer conversion on nVHE TLB invalidation
- fix initialization of the nVHE code
- simplify handling of capabilities exposed to HYP
- nuke VCPUs caught using a forbidden AArch32 EL0
x86:
- new nested virtualization selftest
- miscellaneous fixes
- make W=1 fixes
- reserve new CPUID bit in the KVM leaves"
