  "message": "[PATCH] i386: PARAVIRT: add kmap_atomic_pte for mapping highpte pages\n\nXen and VMI both have special requirements when mapping a highmem pte\npage into the kernel address space.  These can be dealt with by adding\na new kmap_atomic_pte() function for mapping highptes, and hooking it\ninto the paravirt_ops infrastructure.\n\nXen specifically wants to map the pte page RO, so this patch exposes a\nhelper function, kmap_atomic_prot, which maps the page with the\nspecified page protections.\n\nThis also adds a kmap_flush_unused() function to clear out the cached\nkmap mappings.  Xen needs this to clear out any potential stray RW\nmappings of pages which will become part of a pagetable.\n\n[ Zach - vmi.c will need some attention after this patch.  It wasn\u0027t\n  immediately obvious to me what needs to be done. ]\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy@xensource.com\u003e\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nCc: Zachary Amsden \u003czach@vmware.com\u003e\n",
