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

Pull sparc updates from David Miller:

 1) Move to 4-level page tables on sparc64 and support up to 53-bits of
    physical addressing.  Kernel static image BSS size reduced by
    several megabytes.

 2) M6/M7 cpu support, from Allan Pais.

 3) Move to sparse IRQs, handle hypervisor TLB call errors more
    gracefully, and add T5 perf_event support.  From Bob Picco.

 4) Recognize cdroms and compute geometry from capacity in virtual disk
    driver, also from Allan Pais.

 5) Fix memset() return value on sparc32, from Andreas Larsson.

 6) Respect gfp flags in dma_alloc_coherent on sparc32, from Daniel
    Hellstrom.

 7) Fix handling of compound pages in virtual disk driver, from Dwight
    Engen.

 8) Fix lockdep warnings in LDC layer by moving IRQ requesting to
    ldc_alloc() from ldc_bind().

 9) Increase boot string length to 1024 bytes, from Dave Kleikamp.
