The patch titled
Subject: hugetlb: introduce generic version of hugetlb_free_pgd_range
has been removed from the -mm tree. Its filename was
hugetlb-introduce-generic-version-of-hugetlb_free_pgd_range.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Alexandre Ghiti <alex@xxxxxxxx>
Subject: hugetlb: introduce generic version of hugetlb_free_pgd_range
arm, arm64, mips, parisc, sh, x86 architectures use the same version of
hugetlb_free_pgd_range, so move this generic implementation into
asm-generic/hugetlb.h.
