Subject[PATCH for review] [27/48] i386: move PIT function declarations and constants to correct header file
Date

From: Thomas Gleixner <tglx@linutronix.de>

setup_pit_timer is declared in asm-i386/timer.h. Move it to the pit header
file, so it can be used by x86_64 as well.

Move also the PIT constants.
