    Subject[PATCH 3.4 007/172] axonram: Fix bug in direct_access
    Date
    From: Matthew Wilcox <matthew.r.wilcox@intel.com>

    3.4.108-rc1 review patch. If anyone has any objections, please let me know.

    ------------------


    commit 91117a20245b59f70b563523edbf998a62fc6383 upstream.

    The 'pfn' returned by axonram was completely bogus, and has been since
    2008.
