sparc64: Probe cpu page size support more portably. On sun4v, interrogate the machine description. This code is extremely defensive in nature, and a lot of the checks can probably be removed. On sun4u things are a lot simpler. There are the page sizes all chips support, and then Panther adds 32MB and 256MB pages. Report the probed value in /proc/cpuinfo Signed-off-by: David S.
