Subject: [PATCH 1/3] arm64: move the PTE_VALID to pgtable-hwdef.h
Date: Mon, 30 May 2016 10:14:26 +0800 [thread overview]
Message-ID: <1464574468-22700-1-git-send-email-shijie.huang@arm.com> (raw)
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.
