Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (33 commits) [MIPS] Add missing backslashes to macro definitions. [MIPS] Death list of board support to be removed after 2.6.18. [MIPS] Remove BSD and Sys V compat data types. [MIPS] ioc3.h: Uses u8, so include <linux/types.h>. [MIPS] 74K: Assume it will also have an AR bit in config7 [MIPS] Treat CPUs with AR bit as physically indexed. [MIPS] Oprofile: Support VSMP on 34K. [MIPS] MIPS32/MIPS64 S-cache fix and cleanup [MIPS] excite: PCI makefile needs to use += if it wants a chance to work. [MIPS] excite: plat_setup -> plat_mem_setup. [MIPS] au1xxx: export dbdma functions [MIPS] au1xxx: dbdma, no sleeping under spin_lock [MIPS] au1xxx: fix PSC_SMBTXRX_RSR. [MIPS] Early printk for IP27. [MIPS] Fix handling of 0 length I & D caches. [MIPS] Typo fixes. [MIPS] MIPS32/MIPS64 secondary cache management [MIPS] Fix FIXADDR_TOP for TX39/TX49. [MIPS] Remove first timer interrupt setup in wrppmc_timer_setup() [MIPS] Fix configuration of R2 CPU features and multithreading. ...
