X-Git-Tag: v2.6.26-rc7~20^2~25^2~8 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=051c256f672efa356a4cda1841132dbc86541090;p=linux-2.6 rt2x00: Restrict DMA to 32-bit addresses. None of the rt2x00 PCI devices support 64-bit DMA addresses (they all only accept 32-bit buffer addresses). Hence it makes no sense to try to enable 64-bit DMA addresses. Only try to enable 32-bit DMA addresses. Signed-off-by: Gertjan van Wingerde Signed-off-by: Ivo van Doorn Signed-off-by: John W.
