It's useful to know which mm is allocating a pagetable. Xen uses this
to determine whether the pagetable being added to is pinned or not.Signed-off-by: Jeremy Fitzhardinge

SLUB cannot run on i386 at this point because i386 uses the page->private and
page->index field of slab pages for the pgd cache.Make SLUB run on i386 by replacing the pgd slab cache with a quicklist.
Limit the changes as much as possible. Leave the improvised linked list in place
etc etc. This has been working here for a couple of weeks now.Acked-by: William Lee Irwin III

Move inclusion of asm/fixmap.h to where it is really used rather than
where it may have been used long ago (requires a few other adjustments
to includes due to previous implicit dependencies).Signed-off-by: Jan Beulich

The VMI backend uses explicit page type notification to track shadow page
tables. The allocation of page table roots is especially tricky. We need to
clone the root for non-PAE mode while it is protected under the pgd lock to
correctly copy the shadow.We don't need to allocate pgds in PAE mode, (PDPs in Intel terminology) as
they only have 4 entries, and are cached entirely by the processor, which
makes shadowing them rather simple.For base page table level allocation, pmd_populate provides the exact hook
point we need. Also, we need to allocate pages when splitting a large page,
and we must release pages before returning the page to any free pool.Despite being required with these slightly odd semantics for VMI, Xen also
uses these hooks to determine the exact moment when page tables are created or
released.AK: All nops for other architectures

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
