Merge branch 'cris' of git://www.jni.nu/cris

* 'cris' of git://www.jni.nu/cris: (158 commits)
  CRIS v32: Remove hwregs/timer_defs.h, it is now architecture specific.
  CRIS v32: Change drivers/i2c.c locking.
  CRIS v32: Rewrite ARTPEC-3 gpio driver to avoid volatiles and general cleanup.
  CRIS: Add new timerfd syscall entries.
  MAINTAINERS: Add my information for the CRIS port.
  CRIS v32: Correct spelling of bandwidth in function name.
  CRIS v32: Clean up nandflash.c for ARTPEC-3 and ETRAX FS.
  CRIS v10: Cleanup of drivers/gpio.c
  CRIS v10: drivers/net/cris/eth_v10.c rename LED defines to CRIS_LED to avoid name clash.
  CRIS: Make io_pwm_set_period members unsigned in etraxgpio.h
  CRIS: Move ETRAX_AXISFLASHMAP to common Kconfig file.
  CRIS: Drop regs parameter from call to profile_tick in kernel/time.c
  CRIS v32: Fix minor formatting issue in mach-a3/io.c
  CRIS v32: Initialize GIO even if we're rambooting in kernel/head.S
  CRIS v32: Remove kernel/arbiter.c, it now exists in machine dependent directory.
  CRIS v32: Minor changes to avoid errors in asm-cris/arch-v32/hwregs/reg_rdwr.h
  CRIS v32: arch-v32/hwregs/intr_vect_defs.h moved to machine dependent directory.
  CRIS v32: Correct offset for TASK_pid in asm-cris/arch-v32/offset.h
  CRIS v32: Move register map header to machine dependent directory.
  CRIS v32: Let compiler know that memory is clobbered after a break op.
