Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://git.linux-mips.org/pub/scm/upstream-linus: (31 commits) MIPS: Close races in TLB modify handlers. MIPS: Add uasm UASM_i_SRL_SAFE macro. MIPS: RB532: Use hex_to_bin() MIPS: Enable cpu_has_clo_clz for MIPS Technologies' platforms MIPS: PowerTV: Provide cpu-feature-overrides.h MIPS: Remove pointless return statement from empty void functions. MIPS: Limit fixrange_init() to the FIXMAP region MIPS: Install handlers for software IRQs MIPS: Move FIXADDR_TOP into spaces.h MIPS: Add SYNC after cacheflush MIPS: pfn_valid() is broken on low memory HIGHMEM systems MIPS: HIGHMEM DMA on noncoherent MIPS32 processors MIPS: topdown mmap support MIPS: Remove redundant addr_limit assignment on exec. MIPS: AR7: Replace __attribute__((__packed__)) with __packed MIPS: AR7: Remove 'space before tabs' in platform.c MIPS: Lantiq: Add missing clk_enable and clk_disable functions. MIPS: AR7: Fix trailing semicolon bug in clock.c MAINTAINERS: Update MIPS entry. MIPS: BCM63xx: Remove duplicate PERF_IRQSTAT_REG definition ...
