X-Git-Tag: v2.6.20-rc1~34^2~40^2~8^2~132
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7c719871ff4d5f15b71f0138d08b758281b58631;p=linux-2.6

[PATCH] ibmveth: Remove ibmveth "liobn" field

Remove the now unused "liobn" field in ibmveth which also avoids
having insider knowledge of the iommu table in that driver.
