Pull arm64 fix from Will Deacon: "Fix pte_same() to avoid getting stuck on write fault. This single arm64 fix is a revert of 747a70e6 ("arm64: Fix copy-on-write referencing in HugeTLB"), not because that patch was wrong, but because it was broken by aa57157b ("arm64: Ensure VM_WRITE|VM_SHARED ptes are clean by default") which we merged in -rc6. We spotted the issue in Android (AOSP), where one of the JIT threads gets stuck on a write fault during boot because the faulting pte is marked as PTE_DIRTY | PTE_WRITE | PTE_RDONLY and the fault handler decides that there's nothing to do thanks to pte_same() masking out PTE_RDONLY. Thanks to John Stultz for reporting this and testing this so quickly, and to Steve Capper for confirming that the HugeTLB tests continue to pass" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Do not mask out PTE_RDONLY in pte_same()
