X-Git-Tag: v2.6.12~67^2~1 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=86ebacd360767f6a5cf9c8810977593dccf3f3da;p=linux-2.6 [IA64] Update comment to describe modes set in default control register. Christian Hildner pointed out that the comment did not match what the code does in cpu_init() when we set up the default control register. Patch based on suggestions from Ken Chen.
