Hi Paolo, Here's the latest set of fixes for 5.9. The first patch is pretty nasty, as a guest hitting this bug will have its vcpu stuck on a fault, without any hope of it being resolved. Embarrassing, and definitely a stable candidate. The second patch is only a cleanup after the first one. Please pull, M. The following changes since commit 7b75cd5128421c673153efb1236705696a1a9812: KVM: arm64: Update page shift if stage 2 block mapping not supported (2020-09-04 10:53:48 +0100) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-fixes-5.9-2 for you to fetch changes up to 620cf45f7a516bf5fe9e5dce675a652e935c8bde: KVM: arm64: Remove S1PTW check from kvm_vcpu_dabt_iswrite() (2020-09-18 18:01:48 +0100) ---------------------------------------------------------------- KVM/arm64 fixes for 5.9, take #2 - Fix handling of S1 Page Table Walk permission fault at S2 on instruction fetch - Cleanup kvm_vcpu_dabt_iswrite() ---------------------------------------------------------------- Marc Zyngier (2): KVM: arm64: Assume write fault on S1PTW permission fault on instruction fetch KVM: arm64: Remove S1PTW check from kvm_vcpu_dabt_iswrite() arch/arm64/include/asm/kvm_emulate.h | 14 +++++++++++--- arch/arm64/kvm/hyp/include/hyp/switch.h | 2 +- arch/arm64/kvm/mmu.c | 4 ++-- 3 files changed, 14 insertions(+), 6 deletions(-)
