  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
