    MM: virtual address debug · 59ea7463
    Jiri Slaby authored
    Add some (configurable) expensive sanity checking to catch wrong address
    translations on x86.
    - create linux/mmdebug.h file to be able include this file in
      asm headers to not get unsolvable loops in header files
    - __phys_addr on x86_32 became a function in ioremap.c since
      PAGE_OFFSET, is_vmalloc_addr and VMALLOC_* non-constasts are undefined
      if declared in page_32.h
    - add __phys_addr_const for initializing doublefault_tss.__cr3
    Tested on 386, 386pae, x86_64 and x86_64 numa=fake=2.
    Contains Andi's enable numa virtual address debug patch.
