Subject: [PATCH v3 07/11] hugetlb: Introduce generic version of huge_pte_wrprotect
Date: Thu, 05 Jul 2018 05:16:36 +0000 [thread overview]
Message-ID: <20180705051640.790-8-alex@ghiti.fr> (raw)
In-Reply-To: <20180705051640.790-1-alex@ghiti.fr>
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.
