[PATCH 5/10] Paravirt kmap_atomic_pte tidy.patch
Don't implement native_kmap_atomic_pte for !HIGHPTE case; it is never needed,
never called, and leaving it in is just plain confusing. Making it isolated
to the config where it is used may help find bugs.

[PATCH 8/10] Vmi kmap_atomic_pte fix.patch
Implement vmi_kmap_atomic_pte in terms of the backend set_linear_mapping
operation. The conversion is rather straighforward; call kmap_atomic
and then inform the hypervisor of the page mapping.
The _flush_tlb damage is due to macros being pulled in from highmem.h.

[PATCH 0/10] i386, VMI, BusLogic, Timer fixes for -mm
...lied patches. If the
paravirt or VMI patches reject let me know; we are cleaning up
tree and will redo.
Otherwise, I have 4 fixes for i386; a warning fix in sysenter
which is quite serious; some less important warning removals,
and a bug with pgd locking during root creation.
Next, I tidy up the kmap_atomic_pte code, since it makes no
sense to leave it around under !HIGHMEM and being forced to
define it introduces conflicts with where things get defined
that just is ugly.
Some VMI fixes; we support COMPAT_VDSO now that the relocation
code is there, re-add the lazy MMU fix now that Jeremy's cleanups
