Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle: "This has been sitting in -next for a while with no objections and all MIPS defconfigs except one are building fine; that one platform got broken by another patch in your tree and I'm going to submit a patch separately. - a handful of fixes that didn't make 3.11 - a few bits of Octeon 3 support with more to come for a later release - platform enhancements for Octeon, ath79, Lantiq, Netlogic and Ralink SOCs - a GPIO driver for the Octeon - some dusting off of the DECstation code - the usual dose of cleanups" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (65 commits) MIPS: DMA: Fix BUG due to smp_processor_id() in preemptible code MIPS: kexec: Fix random crashes while loading crashkernel MIPS: kdump: Skip walking indirection page for crashkernels MIPS: DECstation HRT calibration bug fixes MIPS: Export copy_from_user_page() (needed by lustre) MIPS: Add driver for the built-in PCI controller of the RT3883 SoC MIPS: DMA: For BMIPS5000 cores flush region just like non-coherent R10000 MIPS: ralink: Add support for reset-controller API MIPS: ralink: mt7620: Add cpu-feature-override header MIPS: ralink: mt7620: Add spi clock definition MIPS: ralink: mt7620: Add wdt clock definition MIPS: ralink: mt7620: Improve clock frequency detection MIPS: ralink: mt7620: This SoC has EHCI and OHCI hosts MIPS: ralink: mt7620: Add verbose ram info MIPS: ralink: Probe clocksources from OF MIPS: ralink: Add support for systick timer found on newer ralink SoC MIPS: ralink: Add support for periodic timer irq MIPS: Netlogic: Built-in DTB for XLP2xx SoC boards MIPS: Netlogic: Add support for USB on XLP2xx MIPS: Netlogic: XLP2xx update for I2C controller ...
