Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle: "This is the main pull request for MIPS for 4.8. Also includes is a minor SSB cleanup as SSB code traditionally is merged through the MIPS tree: ATH25: - MIPS: Add default configuration for ath25 Boot: - For zboot, copy appended dtb to the end of the kernel - store the appended dtb address in a variable BPF: - Fix off by one error in offset allocation Cobalt code: - Fix typos Core code: - debugfs_create_file returns NULL on error, so don't use IS_ERR for testing for errors. - Fix double locking issue in RM7000 S-cache code. This would only affect RM7000 ARC systems on reboot. - Fix page table corruption on THP permission changes. - Use compat_sys_keyctl for 32 bit userspace on 64 bit kernels. David says, there are no compatibility issues raised by this fix. - Move some signal code around. - Rewrite r4k count/compare clockevent device registration such that min_delta_ticks/max_delta_ticks files are guaranteed to be initialized. - Only register r4k count/compare as clockevent device if we can assume the clock to be constant. - Fix MSA asm warnings in control reg accessors - uasm and tlbex fixes and tweaking. - Print segment physical address when EU=1. - Define AT_VECTOR_SIZE_ARCH for ARCH_DLINFO. - CP: Allow booting by VP other than VP 0 - Cache handling fixes and optimizations for r4k class caches - Add hotplug support for R6 processors - Cleanup hotplug bits in kconfig - traps: return correct si code for accessing nonmapped addresses - Remove cpu_has_safe_index_cacheops Lantiq: - Register IRQ handler for virtual IRQ number - Fix EIU interrupt loading code - Use the real EXIN count - Fix build error. Loongson 3: - Increase HPET_MIN_PROG_DELTA and decrease HPET_MIN_CYCLES Octeon: - Delete built-in DTB pruning code for D-Link DSR-1000N. - Clean up GPIO definitions in dlink_dsr-1000n.dts. - Add more LEDs to the DSR-100n DTS - Fix off by one in octeon_irq_gpio_map() - Typo fixes - Enable SATA by default in cavium_octeon_defconfig - Support readq/writeq() - Remove forced mappings of USB interrupts. - Ensure DMA descriptors are always in the low 4GB - Improve USB reset code for OCTEON II. Pistachio: - Add maintainers entry for pistachio SoC Support - Remove plat_setup_iocoherency Ralink: - Fix pwm UART in spis group pinmux. SSB: - Change bare unsigned to unsigned int to suit coding style Tools: - Fix reloc tool compiler warnings. Other: - Delete use of ARCH_WANT_OPTIONAL_GPIOLIB" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (61 commits) MIPS: mm: Fix definition of R6 cache instruction MIPS: tools: Fix relocs tool compiler warnings MIPS: Cobalt: Fix typo MIPS: Octeon: Fix typo MIPS: Lantiq: Fix build failure MIPS: Use CPHYSADDR to implement mips32 __pa MIPS: Octeon: Dlink_dsr-1000n.dts: add more leds. MIPS: Octeon: Clean up GPIO definitions in dlink_dsr-1000n.dts. MIPS: Octeon: Delete built-in DTB pruning code for D-Link DSR-1000N. MIPS: store the appended dtb address in a variable MIPS: ZBOOT: copy appended dtb to the end of the kernel MIPS: ralink: fix spis group pinmux MIPS: Factor o32 specific code into signal_o32.c MIPS: non-exec stack & heap when non-exec PT_GNU_STACK is present MIPS: Use per-mm page to execute branch delay slot instructions MIPS: Modify error handling MIPS: c-r4k: Use SMP calls for CM indexed cache ops MIPS: c-r4k: Avoid small flush_icache_range SMP calls MIPS: c-r4k: Local flush_icache_range cache op override MIPS: c-r4k: Split r4k_flush_kernel_vmap_range() ...
