Subject: [PATCH 3.2 010/221] axonram: Fix bug in direct_access
3.2.69-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Wilcox <matthew.r.wilcox@...el.com>
commit 91117a20245b59f70b563523edbf998a62fc6383 upstream.
The 'pfn' returned by axonram was completely bogus, and has been since
2008.
