Pull sparc fixes from David Miller:

 1) Fix race in sparc64 TLB shootdowns, we have to synchronize with the
    sibling cpus completing if we are passing them a reference via
    pointer to a data structure.

 2) Fix cleaning of bitmaps in sparc32, from Akinobu Mita.

 3) Fix various sparc header mistakes, some of which resulted in
    userland build breakage.  From Sam Ravnborg.

 4) Kill ghost declarations and defines missed when several bits of code
    got deleted recently.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
  sparc64: Fix race in TLB batch processing.
  sparc: use asm-generic version of types.h
  bbc_i2c: fix section mismatch warning
  sparc: use generic headers
  sparc:cleanup unused code in smp_32.h
  sparc/iommu: fix typo s/265KB/256KB/
  sparc/srmmu: clear trailing edge of bitmap properly
  sparc:remove unused declaration smp_boot_cpus()
