Merge branch 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6
* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6: [SPARC32]: Make flush_tlb_kernel_range() an inline function. [SERIAL]: Fix 32-bit warnings in sunzilog.c and sunsu.c [SPARC32]: Kill unused vars and macros from prom/console.c [SPARC32]: Add __cmpdi2() libcall implementation ala. MIPS. [VIDEO]: Do not prom_halt() in cg3 and bw2 device probe. [SUNVDC]: Use slice 0xff on VD_DISK_TYPE_DISK.
