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 -...

Hi Linus, Here's a set of patches to update paravirt_ops and Xen for 2.6.24 A quick overview of the patchset: paravirt_ops: Remove the monolithic paravirt_ops structure, and replace it with smaller structures of related functions. Also, clean up the handling of lazy mode to make it easier to implement. x86/mm/init.c: remove a chunk of dead code Xen: - remove duplicate includes -

Hi Andi, This series of patches implements the Xen paravirt-ops interface. It applies to 2.6.21-rc7 + your patches + the last batch of pv_ops patches I posted. This patch generally restricts itself to Xen-specific parts of the tree, though it does make a few small changes elsewhere. These patches include: - some helper routines for allocating address space and walking pagetables - Xen
