Subject: [ARM] always allow dump_stack() to produce a backtrace
X-Git-Tag: v2.6.22~22^2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=082f47a79bfc8a526b9a3e14a0ae9504fc09cc12;p=linux-2.6

[ARM] always allow dump_stack() to produce a backtrace

Don't make this dependent on CONFIG_DEBUG_KERNEL - if we hit a WARN_ON
we need the stack trace to work out how we got to that point.
