#     Pull KVM updates from Paolo Bonzini:
#      "Much x86 work was pushed out to 5.12, but ARM more than made up for it.
#     
#       ARM:
#        - PSCI relay at EL2 when "protected KVM" is enabled
#        - New exception injection code
#        - Simplification of AArch32 system register handling
#        - Fix PMU accesses when no PMU is enabled
#        - Expose CSV3 on non-Meltdown hosts
#        - Cache hierarchy discovery fixes
#        - PV steal-time cleanups
#        - Allow function pointers at EL2
#        - Various host EL2 entry cleanups
#        - Simplification of the EL2 vector allocation
#     
#       s390:
#        - memcg accouting for s390 specific parts of kvm and gmap
#        - selftest for diag318
#        - new kvm_stat for when async_pf falls back to sync
#     
#       x86:
#        - Tracepoints for the new pagetable code from 5.10
#        - Catch VFIO and KVM irqfd events before userspace
#        - Reporting dirty pages to userspace with a ring buffer
#        - SEV-ES host support
#        - Nested VMX support for wait-for-SIPI activity state
#        - New feature flag (AVX512 FP16)
#        - New system ioctl to report Hyper-V-compatible paravirtualization features
#     
#       Generic:
#        - Selftest improvements"
