Merge branch 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://ftp.linux-mips.org/pub/scm/upstream-linus: (37 commits) MIPS: Only write c0_framemask on CPUs which have this register. MIPS: Alchemy: new userspace suspend interface for development boards. MIPS: Alchemy: dbdma suspend/resume support. MIPS: Alchemy: Fix up PM code on Au1550/Au1200 MIPS: Alchemy: move calc_clock function. MIPS: Alchemy: RTC counter clocksource / clockevent support. MIPS: make cp0 counter clocksource/event usable as fallback. MIPS: Alchemy: remove cpu_table. MIPS: Alchemy: remove get/set_au1x00_lcd_clock(). MIPS: Print irq handler description MIPS: Alchemy: pb1200: update CPLD cascade irq handler. MIPS: Alchemy: update core interrupt code. MIPS: Alchemy: move commandline mangling out of common code MIPS: Alchemy: devboards: consolidate files MIPS: Alchemy: Move development board code to common subdirectory MIPS: Add Cavium OCTEON to arch/mips/Kconfig MIPS: Add defconfig for Cavium OCTEON. MIPS: Adjust the dma-common.c platform hooks. MIPS: Add Cavium OCTEON slot into proper tlb category. MIPS: Compute branch returns for Cavium OCTEON specific branch instructions. ...
