| H A D | memory.h | diff 08bbc9da92f7e44b9c208c6a1adba70c403b255e Mon Feb 09 14:05:46 CST 2009 Alex Nixon <alex.nixon@citrix.com> xen: Add xen_create_contiguous_region
A memory region must be physically contiguous in order to be accessed
through DMA. This patch adds xen_create_contiguous_region, which
ensures a region of contiguous virtual memory is also physically
contiguous.
Based on Stephen Tweedie's port of the 2.6.18-xen version.
Remove contiguous_bitmap[] as it's no longer needed.
Ported from linux-2.6.18-xen.hg 707:e410857fd83c
[ Impact: add Xen-internal API to make pages phys-contig ]
