Fix a 2.6.24-rc3 UML build breakage introduced by commit
1032c0ba9da5c5b53173ad2dcf8b2a2da78f8b17 - it introduces X86_32, with
many things which UML needs depending on it.
This patch adds definitions of X86_32 and RWSEM_XCHGADD_ALGORITHM to
the UML/i386 Kconfig.

No, because if the page isn't mapped, handle_page_fault would have
returned non-zero, and we would have already returned.

UML process, since that has to end on a pgdir boundary, is replaced by

This patch:
um_virt_to_phys only has one user, so it can be moved to the same file
and made static. Its declarations in pgtable.h and ksyms.c are also
gone.
current_cmd was another apparent user, but it itself isn't used, so it
is deleted.

Turn um_virt_to_phys into virt_to_pte, cleaning up a horrid interface.
It's also made non-static and declared in pgtable.h because it'll be
needed when the stubs get a vma.

These patches are for 2.6.25. They change the code that handles stub
pages - a complete description of the patchset is included with the

I wouldn't.
sparc includes swap.h in its pgtable.h. Adding pagemap.h to swap.h
completes an include loop on sparc
