Subject: [PATCH V2 04/11] powerpc/mm/radix: rename _PAGE_LARGE to R_PAGE_LARGE
Date: Thu, 16 Mar 2017 16:02:02 +0530	[thread overview]
Message-ID: <1489660329-22501-5-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1489660329-22501-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>

This bit is only used by radix and it is nice to follow the naming style of having
bit name start with H_/R_ depending on which translation mode they are used.

No functional change in this patch.
