From mboxrd@z Thu Jan 1 00:00:00 1970 From: shijie.huang@arm.com (Huang Shijie) Date: Mon, 30 May 2016 10:14:26 +0800 Subject: [PATCH 1/3] arm64: move the PTE_VALID to pgtable-hwdef.h Message-ID: <1464574468-22700-1-git-send-email-shijie.huang@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The PTE_VALID is used to check whether the page descriptor is valid. It's not a software defined PTE bits, such as PTE_WRITE/PTE_DIRTY. So move it to the proper header file: pgtable-hwdef.h.
