Subject: sparc64: Kill VERBOSE_SHOWREGS code.
X-Git-Tag: v2.6.27-rc2~74^2~4
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a014821340f068bea2fd39cb2578a043fc0dfc57;p=linux-2.6

sparc64: Kill VERBOSE_SHOWREGS code.

It just clutters everything up and even though I wrote that hack I
can't remember having used it in the last 5 years or so.
