X-Git-Tag: v2.6.16-rc3~137^2 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b38c73995f63fe205c0068cb0ce3131895244068;p=linux-2.6 [MIPS] Clear ST0_RE on bootup. The reset state is undefined and some firmware doesn't clear this bit possibly resulting in crashes on entry into userland.
