X-Git-Tag: v2.6.20-rc1~34^2~20^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3417f33e762bf7d4277031a655e3ad07e73ce0be;p=pandora-kernel.git drm: add flag for mapping PCI DMA buffers read-only. Add DRM_PCI_BUFFER_RO flag for mapping PCI DMA buffer read-only. An additional flag is needed, since PCI DMA buffers do not have an associated map.
