address ranges, and a set of support functions working with it. * Changed the type of the kernel_args physical address range arrays to phys_addr_range and adjusted the code working with those. * Removed a bunch of duplicated address range code in the PPC's mmu.cpp. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36947 a95241bf-73f2-0310-859d-f6bbb57e9c96
