X-Git-Tag: v2.6.23-rc1~784^2~20 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2c4f4ecb7a421e0be6632d3366f0bc7cdf1e38b1;p=linux-2.6 [SPARC64]: Add domain-services nodes to VIO device tree. They sit under the root of the MD tree unlike the rest of the LDC channel based virtual devices. Signed-off-by: David S.
