Subject: [PATCH v3 05/11] hugetlb: Introduce generic version of huge_ptep_clear_flush
Date: Thu, 05 Jul 2018 05:16:34 +0000 [thread overview]
Message-ID: <20180705051640.790-6-alex@ghiti.fr> (raw)
In-Reply-To: <20180705051640.790-1-alex@ghiti.fr>
arm, x86 architectures use the same version of
huge_ptep_clear_flush, so move this generic implementation into
asm-generic/hugetlb.h.
