[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. Signed-off-by: Zachary Amsden <zach@vmware.com> diff -r 5c03805411a6 arch/i386/kernel/paravirt.c --- a/arch/i386/kernel/par...

[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. Signed-off-by: Zachary Amsden <zach@vmware.com> diff...

[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...
