Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next

Pull sparc updates from David Miller:

 1) Add sparc RAM output to /proc/iomem, from Bob Picco.

 2) Allow seeks on /dev/mdesc, from Khalid Aziz.

 3) Cleanup sparc64 I/O accessors, from Sam Ravnborg.

 4) If update_mmu_cache{,_pmd}() is called with an not-valid mapping, do
    not insert it into the TLB miss hash tables otherwise we'll
    livelock.  Based upon work by Christopher Alexander Tobias Schulze.

 5) Fix BREAK detection in sunsab driver when no actual characters are
    pending, from Christopher Alexander Tobias Schulze.

 6) Because we have modules --> openfirmware --> vmalloc ordering of
    virtual memory, the lazy VMAP TLB flusher can cons up an invocation
    of flush_tlb_kernel_range() that covers the openfirmware address
    range.  Unfortunately this will flush out the firmware's locked TLB
    mapping which causes all kinds of trouble.  Just split up the flush
    request if this happens, but in the long term the lazy VMAP flusher
    should probably be made a little bit smarter.

    Based upon work by Christopher Alexander Tobias Schulze.
