The new level is called pml4. The patch needs some simple changes to all architectures. Changes compared to 4level-2.6.9rc4-2: - Merged with 2.6.9 (release, not -final) - Converted more architectures. Porting status: - i386 works with 2/3 levels. - x86-64 works with 4 levels. - ppc64 works with 3 levels - ia64 works with 3 levels - sh converted, but was unable to compile because it's broken in mainline - ppc32 converted, compiles, not tested. - alpha converted, boots - sparc64 converted, compiles, not tested - arm*/h8300/cris/m32r/m68k*/mips/parisc/s390/sh64/um/v850: still need to be converted For many of them it's difficult because they don't even compile in mainline. More testing on x86-64 and other architectures and new architecture ports would be appreciated. The changes needed to convert an architecture over are relatively simple, see the i386 port as an example. -Andi
