Zhang Zhen e81f2d2237 mm/hugetlb: reduce arch dependent code about huge_pmd_unshare 
Currently we have many duplicates in definitions of huge_pmd_unshare.  In
all architectures this function just returns 0 when
CONFIG_ARCH_WANT_HUGE_PMD_SHARE is N.

This patch puts the default implementation in mm/hugetlb.c and lets these
architectures use the common code.
