Peter Zijlstra 0e071ee681 m68k: mm: Extend table allocator for multiple sizes ... In addition to the PGD/PMD table size (128*4) add a PTE table size (64*4) to the table allocator. This completely removes the pte-table overhead compared to the old code, even for dense tables. Notes: - the allocator gained a list_empty() check to deal with there not being any pages at all. - the free mask is extended to cover more than the 8 bits required for the (512 byte) PGD/PMD tables. - NR_PAGETABLE accounting is restored.
