Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: [MIPS] Treat R14000 like R10000. [MIPS] Remove EXPERIMENTAL from PAGE_SIZE_16KB [MIPS] Update/Fix instruction definitions [MIPS] DSP and MDMX share the same config flag bit. [MIPS] Fix deadlock on MP with cache aliases. [MIPS] Use generic STABS_DEBUG macro. [MIPS] Create consistency in "system type" selection. [MIPS] Use generic DWARF_DEBUG [MIPS] Fix kgdb exception handler from user mode. [MIPS] Update struct sigcontext member names [MIPS] Update/fix futex assembly [MIPS] Remove support for sysmips(2) SETNAME and MIPS_RDNVRAM operations. [MIPS] Fix detection and handling of the 74K processor. [MIPS] Add missing 34K processor IDs [MIPS] Fix marking buddy of pte global for MIPS32 w/36-bit physical address [MIPS] AU1xxx mips_timer_interrupt() fixes [MIPS] Fix typo
