Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-2.6

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-2.6:
  sparc32: pass -m32 when building vmlinux.lds
  sparc: Fixes the DRM layer build on sparc.
  ide: merge <asm-sparc/ide_64.h> with <asm-sparc/ide_32.h>
  ide: <asm-sparc/ide_64.h>: use __raw_{read,write}w()
  ide: <asm-sparc/ide_32.h>: use __raw_{read,write}w()
  ide: <asm-sparc/ide_64.h>: use %r0 for outw_be()
  sparc64: Do not define BIO_VMERGE_BOUNDARY.
