SPARC64: introduce a convenience function for getting physical addresses
Introduce cpu_sparc_get_phys_page() to be used as a help for splitting cpu_get_phys_page_debug() from cpu_get_phys_page_nofault(). Signed-off-by: Tsuneo Saito <tsnsaito@gmail.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
