The 32bit and the 64bit code are slighty different in the reservation of standard resources. Also the upcoming Moorestown support needs its own version of that. Add it to x86_init_ops and initialize it with the 64bit default. 32bit overrides it in early boot. Now moorestown can add it's own override w/o sprinkling the code with more #ifdefs Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
