Cover letter [PATCH 0/11] alternate 4-level page tables patches (take 2)

OK, it turned out that the fallback header I sent out earlier seemed to do the right thing on both ia64 and x86_64 (3-level) without really any changes. So combined with i386 !PAE, that covers 2-level and 3-level implementations... so with any luck it will work on all arches.

So in the following series, there is:

a minor shuffling of hunks between patches
slight improvement to the clear_page_range patch
one off-by-one bug in clear_pud_range
dropped the inlining patch
inclusion of the fallback header.

Theoretically, all architectures should continue to work as before.

Comments? Any consensus as to which way we want to go? I don't want to inflame tempers by continuing this line of work, just provoke discussion.

Thanks,
Nick
