  KVM: vmx: remove unused variable (2020-10-31 11:38:43 -0400)

----------------------------------------------------------------
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
