Catalin Marinas 6767df245f arm64: Do not mask out PTE_RDONLY in pte_same() ... Following commit 73e86cb03c ("arm64: Move PTE_RDONLY bit handling out of set_pte_at()"), the PTE_RDONLY bit is no longer managed by set_pte_at() but built into the PAGE_* attribute definitions. Consequently, pte_same() must include this bit when checking two PTEs for equality. Remove the arm64-specific pte_same() function, practically reverting commit 747a70e60b ("arm64: Fix copy-on-write referencing in HugeTLB") Fixes: 73e86cb03c ("arm64: Move PTE_RDONLY bit handling out of set_pte_at()") Cc: <stable@vger.kernel.org> # 4.14.x- Cc: Will Deacon <will@kernel.org> Cc: Steve Capper <steve.capper@arm.com> Reported-by: John Stultz <john.stultz@linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Will Deacon <will@kernel.org>		2019-11-06 19:31:56 +00:00
