Matt Turner 533d4a1ef9 alpha: select ARCH_HAS_DEBUG_VM_PGTABLE
CONFIG_DEBUG_VM_PGTABLE runs a boot-time self test over the page table
helpers: the protection bit accessors, pte_modify(), the swap entry
encoding including the exclusive marker, and, where the architecture
supports them, the huge page helpers.  Alpha implements everything the
test needs for a three-level page table without huge page support.

Also mark Alpha as "ok" in the debug-vm-pgtable feature matrix.
