Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/upstream-linus
* 'upstream' of git://git.linux-mips.org/pub/scm/upstream-linus: (46 commits) ftrace/MIPS: Enable C Version of recordmcount ftrace/MIPS: Add module support for C version of recordmcount ftrace/MIPS: Add MIPS64 support for C version of recordmcount MIPS: Make TASK_SIZE reflect proper size for both 32 and 64 bit processes. MIPS: Allow UserLocal on MIPS_R1 processors MIPS: Honor L2 bypass bit MIPS: Add BMIPS CP0 register definitions MIPS: Add BMIPS processor types to Kconfig MIPS: Decouple BMIPS CPU support from bcm47xx/bcm63xx SoC code MIPS: Add support for hardware performance events (mipsxx) MIPS: Perf-events: Add callchain support MIPS: add support for hardware performance events (skeleton) MIPS: add support for software performance events MIPS: define local_xchg from xchg_local to atomic_long_xchg MIPS: AR7: Add support for Titan (TNETV10xx) SoC variant MIPS: AR7: Initialize GPIO earlier MIPS: Add platform device and Kconfig for Octeon USB EHCI / OHCI USB: Add EHCI and OHCH glue for OCTEON II SOCs. MIPS: Octeon: Add register definitions for EHCI / OHCI USB glue logic. MIPS: Octeon: Apply CN63XXP1 errata workarounds. ...
