| |
on top of current linus/master and tip/x86/mm2, but please zap last patch in that branch.
1. use brk to mapping first PMD_SIZE range under end of ram. 2. top down to initialize page table range by range. 3. get rid of calculate_page_table, and find_early_page_table. 4. remove early_ioremap in page table accessing. 5. remove workaround in xen to mark page RO.
v2: changes, update xen interface about pagetable_reserve, so not use pgt_buf_* in xen code directly. v3: use range top-down to initialize page table, so will not use calculating/find early table anymore. also reorder the patches sequence. v4: add mapping_mark_page_ro to fix xen, also move pgt_buf_* to init.c and merge alloc_low_page(), and for 32bit need to add alloc_low_pages to fix 32bit kmap setting. v5: remove mark_page_ro workaround. Add another 5 cleanup patches.
