Subject: [PATCH V2 04/68] powerpc/mm: Use big endian page table for book3s 64
Date: Sat, 9 Apr 2016 11:43:00 +0530 [thread overview]
Message-ID: <1460182444-2468-5-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1460182444-2468-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
This enables us to share the same page table code for
both radix and hash. Radix use a hardware defined big endian
page table
