Subject: IPMI: Convert system interface defines to an enum
X-Git-Tag: v2.6.26-rc1~521
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ba8ff1c61eb119e687b06ca35f7f4ab041bf0422;p=linux-2.6

IPMI: Convert system interface defines to an enum

Convert the #defines for statistics into an enum in the IPMI system interface
and remove the unused timeout_restart statistic.  And comment what these
statistics mean.
