- Merge physmem_pgt and ident_pgt, removing physmem_pgt. The merge is broken as soon as mm/init.c:init_memory_mapping is run. - As physmem_pgt is gone don't export it in pgtable.h. - Use defines from pgtable.h for page permissions. - Fix the physical memory identity mapping so it is at the correct address. - Remove the physical memory mapping from wakeup_level4_pgt it is at the wrong address so we can't possibly be usinging it. - Simply NEXT_PAGE the work to calculate the phys_ alias of the labels was very cool. Unfortuantely it was a brittle special purpose hack that makes maitenance more difficult. Instead just use label - __START_KERNEL_map like we do everywhere else in assembly. Signed-off-by: Eric W.
