Subject: [RFC PATCH v2 3/4] powerpc: Don't bolt the hpte in kernel_map_linear_page()
Date: Fri, 12 Apr 2013 10:16:59 +0800 [thread overview]
Message-ID: <1365733021-28912-4-git-send-email-zhong@linux.vnet.ibm.com> (raw)
In-Reply-To: <1365733021-28912-1-git-send-email-zhong@linux.vnet.ibm.com>
It seems that in kernel_unmap_linear_page(), it only checks whether there
is a map in the linear_map_hash_slots array, so seems we don't need bolt
the hpte.
