This series contains a somewhat random set of reworks and improvements to the
KVM/Arm code in preparation for nested virtualization support.

We plan to merge these as early as v5.1.

The series relies on an additional patch which exposes the physical EL1 timer's
IRQ number to KVM:
"clocksource/arm_arch_timer: Store physical timer IRQ number for KVM on VHE"

Andre Przywara (1):
KVM: arm/arm64: consolidate arch timer trap handlers

Christoffer Dall (6):
KVM: arm/arm64: Factor out VMID into struct kvm_vmid
KVM: arm/arm64: Simplify bg_timer programming
KVM: arm/arm64: timer: Rework data structures for multiple timers
KVM: arm/arm64: arch_timer: Assign the phys timer on VHE systems
KVM: arm/arm64: Rework the timer code to use a timer_map
KVM: arm/arm64: Move kvm_is_write_fault to header file

Marc Zyngier (7):
arm/arm64: KVM: Introduce kvm_call_hyp_ret()
arm64: KVM: Allow for direct call of HYP functions when using VHE
arm64: KVM: Drop VHE-specific HYP call stub
ARM: KVM: Teach some form of type-safety to kvm_call_hyp
arm/arm64: KVM: Statically configure the host's view of MPIDR
KVM: arm64: Fix ICH_ELRSR_EL2 sysreg naming
KVM: arm64: Reuse sys_reg() macro when searching the trap table
