Subject: sh: Wire up kdump crash kernel exec in die().
X-Git-Tag: v2.6.22-rc3~94^2~2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e113276624104d9c3b25f333d8dd999b804d980a;p=linux-2.6

sh: Wire up kdump crash kernel exec in die().

Now that we have the basic kdump support in place, add it in to
die() so we can enter the crash kernel automatically.
