arm64: Fix typo in the pmdp_huge_get_and_clear() definition
With hardware AF/DBM support, pmd modifications (transparent huge pages) should be performed atomically using load/store exclusive. The initial patches defined the get-and-clear function and __HAVE_ARCH_* macro without the "huge" word, leaving the pmdp_huge_get_and_clear() to the default, non-atomic implementation. Fixes: 2f4b829c625e ("arm64: Add support for hardware updates of the access and dirty pte bits") Cc: <stable@vger.kernel.org> # 4.3+ Reviewed-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
