The patch titled
Subject: hugetlb: introduce generic version of huge_pte_wrprotect
has been removed from the -mm tree. Its filename was
hugetlb-introduce-generic-version-of-huge_pte_wrprotect.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 huge_pte_wrprotect
arm, arm64, ia64, mips, parisc, powerpc, sh, sparc, x86 architectures use
the same version of huge_pte_wrprotect, so move this generic
implementation into asm-generic/hugetlb.h.
