Subject[PATCH v2 0/2] KVM: Fix refaulting due to page table update

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



Punit Agrawal (2):
KVM: arm/arm64: Skip updating PMD entry if no change
KVM: arm/arm64: Skip updating PTE entry if no change
