Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle: - Improvements to the tlb_dump code - KVM fixes - Add support for appended DTB - Minor improvements to the R12000 support - Minor improvements to the R12000 support - Various platform improvments for BCM47xx - The usual pile of minor cleanups - A number of BPF fixes and improvments - Some improvments to the support for R3000 and DECstations - Some improvments to the ATH79 platform support - A major patchset for the JZ4740 SOC adding support for the CI20 platform - Add support for the Pistachio SOC - Minor BMIPS/BCM63xx platform support improvments. - Avoid "SYNC 0" as memory barrier when unlocking spinlocks - Add support for the XWR-1750 board. - Paul's __cpuinit/__cpuinitdata cleanups. - New Malta CPU board support large memory so enable ZONE_DMA32. * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (131 commits) MIPS: spinlock: Adjust arch_spin_lock back-off time MIPS: asmmacro: Ensure 64-bit FP registers are used with MSA MIPS: BCM47xx: Simplify handling SPROM revisions MIPS: Cobalt Don't use module_init in non-modular MTD registration. MIPS: BCM47xx: Move NVRAM driver to the drivers/firmware/ MIPS: use for_each_sg() MIPS: BCM47xx: Don't select BCMA_HOST_PCI MIPS: BCM47xx: Add helper variable for storing NVRAM length MIPS: IRQ/IP27: Move IRQ allocation API to platform code. MIPS: Replace smp_mb with release barrier function in unlocks. MIPS: i8259: DT support MIPS: Malta: Basic DT plumbing MIPS: include errno.h for ENODEV in mips-cm.h MIPS: Define GCR_GIC_STATUS register fields MIPS: BPF: Introduce BPF ASM helpers MIPS: BPF: Use BPF register names to describe the ABI MIPS: BPF: Move register definition to the BPF header MIPS: net: BPF: Replace RSIZE with SZREG MIPS: BPF: Free up some callee-saved registers MIPS: Xtalk: Update xwidget.h with known Xtalk device numbers ...
