Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle: "The most notable new addition inside this pull request is the support for MIPS's latest and greatest core called "inter/proAptiv". The patch series describes this core as follows. "The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit." The platform specific patches touch all 3 Broadcom families. It adds support for the new Broadcom/Netlogix XLP9xx Soc, building a common BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count and full gpio button/led descriptions for BCM47xx. The rest of the series are cleanups and bug fixes that are MIPS generic and consist largely of changes that Imgtec/MIPS had published in their linux-mti-3.10.git stable tree. Random other cleanups and patches preparing code to be merged in 3.15" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (139 commits) mips: select ARCH_MIGHT_HAVE_PC_SERIO mips: delete non-required instances of include <linux/init.h> MIPS: KVM: remove shadow_tlb code MIPS: KVM: use common EHINV aware UNIQUE_ENTRYHI mips/ide: flush dcache also if icache does not snoop dcache MIPS: BCM47XX: fix position of cpu_wait disabling MIPS: BCM63XX: select correct MIPS_L1_CACHE_SHIFT value MIPS: update MIPS_L1_CACHE_SHIFT based on MIPS_L1_CACHE_SHIFT_<N> MIPS: introduce MIPS_L1_CACHE_SHIFT_<N> MIPS: ZBOOT: gather string functions into string.c arch/mips/pci: don't check resource with devm_ioremap_resource arch/mips/lantiq/xway: don't check resource with devm_ioremap_resource bcma: gpio: don't cast u32 to unsigned long ssb: gpio: add own IRQ domain MIPS: BCM47XX: fix sparse warnings in board.c MIPS: BCM47XX: add board detection for Linksys WRT54GS V1 MIPS: BCM47XX: fix detection for some boards MIPS: BCM47XX: Enable buttons support on SSB MIPS: BCM47XX: Convert WNDR4500 to new syntax MIPS: BCM47XX: Use "timer" trigger for status LEDs ...
