Linus Torvalds 17fa96334e Arm:
- Fix a couple of embarrassing merge mistakes in kvmarm-7.4
 
 - Cleanup the HCR_EL2 bit fields to exclusively use the generated
   definitions, fixings a nasty regression introduced in 6.16, where
   barriers were not upgraded from NSH to ISH anymore
 
 - Fix publication of state when a vcpu is forced out of the guest
 
 - Let vcpu pausing nest correctly
 
 - Sanitise ID_AA64MMFR3_EL1.S1P[IO]E to follow the rules of the architecture
 
 - Don't warn on SMCCC filter reserved range allocation failure
 
 - Prevent GICv5 and TLBI hypercalls to be used from the host when pKVM
   is active
 
 - Enforce that only GICv3 guests are supported for pKVM
 
 - Don't try to access GICv5 EL2 sysregs from EL1
 
 - Compute architectrally correct values for ID_AA64MMFR3_EL1.S1P[IO]E
   by checking the feature dependencies
 
 - Require matching VGIC and ITS model
 
 - Cleanup TRACE_REMOTE dependencies
 
 - Fix random comments
 
 Arm selftests:
 
 - selftests: Skip unwritable ID fields in the failed-run test
 
 - Move pkvm_selftests() after all CPUs have initialized EL2
 
 RISC-V:
 
 - Allow Zicclsm, Ziccamoa, Ziccif, Za64rs for KVM guest
 
 - Implement KVM_PRE_FAULT_MEMORY ioctl()
 
 - Replace imsic switch-case macros with range checks
 
 RISC-V fixes:
 
 - Avoid redundant interrupt check for pending timers
 
 - Reject vCPU creation after AIA initialization
 
 - Fix build with vector support disabled
 
 - Fix IPI delivery for out-of-order vcpu_id
 
 - Use a raw lock for IMSIC wakeup state
 
 - Reject vCPU creation after AIA initialization
 
 RISC-V selftests:
 
 - Lazy V-extension enablement for KVM selftests
 
 - Show sepc/scause/stval CSRs in KVM selftests vcpu dump
