[GIT PULL] KVM/arm64 fixes for 6.18, take #2

Paolo, Much later than expected, but here's the second set of fixes KVM/arm64 for 6.18. The core changes are mostly fixes for a bunch of recent regressions, plus a couple that address the way pKVM deals with untrusted data. The rest address a couple of selftests, and Oliver's new email address. Please pull, M. The following changes since commit ca88ecdce5f51874a7c151809bd2c936ee0d3805: arm64: Revamp HCR_EL2.E2H RES1 detection (2025-10-14 08:18:40 +0100) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-fixes-6.18-2 for you to fetch changes up to 4af235bf645516481a82227d82d1352b9788903a: MAINTAINERS: Switch myself to using kernel.org address (2025-11-08 11:21:20 +0000) ---------------------------------------------------------------- KVM/arm654 fixes for 6.18, take #2 * Core fixes - Fix trapping regression when no in-kernel irqchip is present (20251021094358.1963807-1-sascha.bischoff(a)arm.com) - Check host-provided, untrusted ranges and offsets in pKVM (20251016164541.3771235-1-vdonnefort(a)google.com) (20251017075710.2605118-1-sebastianene(a)google.com) - Fix regression restoring the ID_PFR1_EL1 register (20251030122707.2033690-1-maz(a)kernel.org - Fix vgic ITS locking issues when LPIs are not directly injected (20251107184847.1784820-1-oupton(a)kernel.org) * Test fixes - Correct target CPU programming in vgic_lpi_stress selftest (20251020145946.48288-1-mdittgen(a)amazon.de) - Fix exposure of SCTLR2_EL2 and ZCR_EL2 in get-reg-list selftest (20251023-b4-kvm-arm64-get-reg-list-sctlr-el2-v1-1-088f88ff992a(a)kernel.org) (20251024-kvm-arm64-get-reg-list-zcr-el2-v1-1-0cd0ff75e22f(a)kernel.org) * Misc - Update Oliver's email address (20251107012830.1708225-1-oupton(a)kernel.org) ---------------------------------------------------------------- Marc Zyngier (3): KVM: arm64: Make all 32bit ID registers fully writable KVM: arm64: Set ID_{AA64PFR0,PFR1}_EL1.GIC when GICv3 is configured KVM: arm64: Limit clearing of ID_{AA64PFR0,PFR1}_EL1.GIC to userspace irqchip Mark Brown (2): KVM: arm64: selftests: Add SCTLR2_EL2 to get-reg-list KVM: arm64: selftests: Filter ZCR_EL2 in get-reg-list Maximilian Dittgen (1): KVM: selftests: fix MAPC RDbase target formatting in vgic_lpi_stress Oliver Upton (3): KVM: arm64: vgic-v3: Reinstate IRQ lock ordering for LPI xarray KVM: arm64: vgic-v3: Release reserved slot outside of lpi_xa's lock MAINTAINERS: Switch myself to using kernel.org address Sascha Bischoff (1): KVM: arm64: vgic-v3: Trap all if no in-kernel irqchip Sebastian Ene (1): KVM: arm64: Check the untrusted offset in FF-A memory share Vincent Donnefort (1): KVM: arm64: Check range args for pKVM mem transitions .mailmap | 3 +- MAINTAINERS | 2 +- arch/arm64/kvm/hyp/nvhe/ffa.c | 9 ++- arch/arm64/kvm/hyp/nvhe/mem_protect.c | 28 +++++++++ arch/arm64/kvm/sys_regs.c | 71 ++++++++++++---------- arch/arm64/kvm/vgic/vgic-debug.c | 16 +++-- arch/arm64/kvm/vgic/vgic-init.c | 16 ++++- arch/arm64/kvm/vgic/vgic-its.c | 18 +++--- arch/arm64/kvm/vgic/vgic-v3.c | 3 +- arch/arm64/kvm/vgic/vgic.c | 23 ++++--- tools/testing/selftests/kvm/arm64/get-reg-list.c | 3 + tools/testing/selftests/kvm/lib/arm64/gic_v3_its.c | 9 ++- 12 files changed, 137 insertions(+), 64 deletions(-)

This has been true ever since this code was added. It seems that hardly anyone (or even no one?) actually uses big endian arm kernels. But as long as they're ostensibly supported, we should disable this code on them so that it's not accidentally used. Note: for future-proofing, use !CPU_BIG_ENDIAN instead of CPU_LITTLE_ENDIAN. Both of these are arch-specific options that could get removed in the future if big endian support gets dropped.
