Hi, Here's a couple of patches to fix an issue when multiple vcpus fault on a page table entry[0]. The issue was reported by a user when testing PUD hugepage support[1] but also exists for PMD and PTE updates though with a lower probability. In this version - * the fix has been split for PMD hugepage and PTE update * refactored the PMD fix * applied fixes tag and cc'ing to stable Thanks, Punit [0] https://lkml.org/lkml/2018/8/10/256 [1] https://lkml.org/lkml/2018/7/16/482 Punit Agrawal (2): KVM: arm/arm64: Skip updating PMD entry if no change KVM: arm/arm64: Skip updating PTE entry if no change virt/kvm/arm/mmu.c | 45 ++++++++++++++++++++++++++++++++++----------- 1 file changed, 34 insertions(+), 11 deletions(-) -- 2.18.0 _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
