[PATCH] m32r: update for profiling

  This patch is for profiling support.
  profile_tick() is used instead of m32r_do_profile().

	* arch/m32r/kernel/smp.c
	(smp_local_timer_interrupt): Change profile API, use profile_tick()
	instead of m32r_do_profile().

	* arch/m32r/kernel/time.c: ditto.

	* include/asm-m32r/hw_irq.h (m32r_do_profile): Removed.

	* include/asm-m32r/ptrace.h (profile_pc): Add profile_pc() macro.
