 ARM:
 
 - Page ownership tracking between host EL1 and EL2
 
 - Rely on userspace page tables to create large stage-2 mappings
 
 - Fix incompatibility between pKVM and kmemleak
 
 - Fix the PMU reset state, and improve the performance of the virtual PMU
 
 - Move over to the generic KVM entry code
 
 - Address PSCI reset issues w.r.t. save/restore
 
 - Preliminary rework for the upcoming pKVM fixed feature
 
 - A bunch of MM cleanups
 
 - a vGIC fix for timer spurious interrupts
 
 - Various cleanups
 
 s390:
 
 - enable interpretation of specification exceptions
 
 - fix a vcpu_idx vs vcpu_id mixup
 
 x86:
 
 - fast (lockless) page fault support for the new MMU
 
 - new MMU now the default
 
 - increased maximum allowed VCPU count
 
 - allow inhibit IRQs on KVM_RUN while debugging guests
 
 - let Hyper-V-enabled guests run with virtualized LAPIC as long as they
   do not enable the Hyper-V "AutoEOI" feature
 
 - fixes and optimizations for the toggling of AMD AVIC (virtualized LAPIC)
 
 - tuning for the case when two-dimensional paging (EPT/NPT) is disabled
 
 - bugfixes and cleanups, especially with respect to 1) vCPU reset and
   2) choosing a paging mode based on CR0/CR4/EFER
 
 - support for 5-level page table on AMD processors
 
 Generic:
 
 - MMU notifier invalidation callbacks do not take mmu_lock unless necessary
 
 - improved caching of LRU kvm_memory_slot
 
 - support for histogram statistics
 
 - add statistics for halt polling and remote TLB flush requests
