Subject: x86, dumpstack: always call oops_exit from oops_end
X-Git-Tag: v2.6.29-rc1~587^2~4^10~4
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=10b14cb7eb7dd5bff8023f76a55c8ac20e586128;p=linux-2.6-omap-h63xx.git

x86, dumpstack: always call oops_exit from oops_end

Always call oops_exit from oops_end, even if signr==0.

Also, move add_taint(TAINT_DIE) from __die to oops_end
on x86_64 and interchange two lines to make oops_end
more similar to the i386-version.
