[PATCH 4.5 03/87] arm64: Fix typo in the pmdp_huge_get_and_clear() definition

[Greg Kroah-Hartman]

4.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Catalin Marinas <catalin.marinas@xxxxxxx>

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.

Fixes: 2f4b829c625e ("arm64: Add support for hardware updates of the access and dirty pte bits")
