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.
