 ARM:
 
 * Unwinder implementations for both nVHE modes (classic and
   protected), complete with an overflow stack
 
 * Rework of the sysreg access from userspace, with a complete
   rewrite of the vgic-v3 view to allign with the rest of the
   infrastructure
 
 * Disagregation of the vcpu flags in separate sets to better track
   their use model.
 
 * A fix for the GICv2-on-v3 selftest
 
 * A small set of cosmetic fixes
 
 RISC-V:
 
 * Track ISA extensions used by Guest using bitmap
 
 * Added system instruction emulation framework
 
 * Added CSR emulation framework
 
 * Added gfp_custom flag in struct kvm_mmu_memory_cache
 
 * Added G-stage ioremap() and iounmap() functions
 
 * Added support for Svpbmt inside Guest
 
 s390:
 
 * add an interface to provide a hypervisor dump for secure guests
 
 * improve selftests to use TAP interface
 
 * enable interpretive execution of zPCI instructions (for PCI passthrough)
 
 * First part of deferred teardown
 
 * CPU Topology
 
 * PV attestation
 
 * Minor fixes
 
 x86:
 
 * Permit guests to ignore single-bit ECC errors
 
 * Intel IPI virtualization
 
 * Allow getting/setting pending triple fault with KVM_GET/SET_VCPU_EVENTS
