Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (47 commits) [MAINTAINERS] The ham radio code now has website at http://www.linux-ax25.org. [MIPS] Use __ffs() instead of ffs() for waybit calculation. [MIPS] Fix Makefile bugs for MIPS32/MIPS64 R1 and R2. [MIPS] Handle IDE PIO cache aliases on SMP. [MIPS] Make mips_srs_init static. [MIPS] MIPS boards: Set HZ to 100. [MIPS] kgdb: Let gcc compute the array size itself. [MIPS] FPU affinity for MT ASE. [MIPS] MT: Improved multithreading support. [MIPS] kpsd and other AP/SP improvements. [MIPS] R2: Instruction hazard barrier. [MIPS] Fix genrtc compilation. [MIPS] R2: Implement shadow register allocation without spinlock. [MIPS] Fix VR41xx build errors. [MIPS] Fix tx49_blast_icache32_page_indexed. [MIPS] Enable SCHED_NO_NO_OMIT_FRAME_POINTER for MIPS. [MIPS] Use "R" constraint for cache_op. [MIPS] Rewrite all the assembler interrupt handlers to C. [MIPS] Fix the crime against humanity that mipsIRQ.S is. [MIPS] Fixup damage done by 22a9835c350782a5c3257343713932af3ac92ee0. ...
