[Xen-devel] [PATCH 0/6] xen: don't call vmalloc_sync_all() when

This set of pages avoids the need to call vmalloc_sync_all() when
mapping foreign pages.  Two new functions are adding for mapping
foreign pages onto RAM pages instead of vmalloc space.

This does waste a page of RAM for each mapped page.  In the future a
ballooned page could be used instead (once the API for getting a
ballooned page with the right GFP flags is available).

David
