Subject: arm64: Fix typo in the pmdp_huge_get_and_clear() definition
From: Catalin Marinas <[email protected]>
commit 911f56eeb87ee378f5e215469268a7a2f68a5a8a upstream.
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.
