Merge tag 'kvmarm-fixes-6.17-1' of https://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

2025-08-29T16:57:31Z

KVM/arm64 changes for 6.17, take #2 - Correctly handle 'invariant' system registers for protected VMs - Improved handling of VNCR data aborts, including external aborts - Fixes for handling of FEAT_RAS for NV guests, providing a sane fault context during SEA injection and preventing the use of RASv1p1 fault injection hardware - Ensure that page table destruction when a VM is destroyed gives an opportunity to reschedule - Large fix to KVM's infrastructure for managing guest context loaded on the CPU, addressing issues where the output of AT emulation doesn't get reflected to the guest - Fix AT S12 emulation to actually perform stage-2 translation when necessary - Avoid attempting vLPI irqbypass when GICv4 has been explicitly disabled for a VM - Minor KVM + selftest fixes

KVM: arm64: Get rid of ARM64_FEATURE_MASK()

2025-08-21T23:31:56Z

The ARM64_FEATURE_MASK() macro was a hack introduce whilst the automatic generation of sysreg encoding was introduced, and was too unreliable to be entirely trusted. We are in a better place now, and we could really do without this macro. Get rid of it altogether.

KVM: selftests: Change MDSCR_EL1 register holding variables as uint64_t

Change MDSCR_EL1 register holding local variables as uint64_t that reflects its true register width as well.

KVM: selftests: Use canonical $(ARCH) paths for KVM selftests directories

2024-12-18T22:15:04Z

Use the kernel's canonical $(ARCH) paths instead of the raw target triple for KVM selftests directories. KVM selftests are quite nearly the only place in the entire kernel that using the target triple for directories, tools/testing/selftests/drivers/s390x being the lone holdout. Using the kernel's preferred nomenclature eliminates the minor, but annoying, friction of having to translate to KVM's selftests directories, e.g. for pattern matching, opening files, running selftests, etc. Opportunsitically delete file comments that reference the full path of the file, as they are obviously prone to becoming stale, and serve no known purpose.
