Subject: sh: Export unwind_stack() to satisfy modular oprofile.
X-Git-Tag: firefly_0821_release~12920^2~35^2~19^2~3
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=4ab8f241f6d510470c15b62ac10f6905ff5c97bd;p=firefly-linux-kernel-4.4.55.git

sh: Export unwind_stack() to satisfy modular oprofile.

If the oprofile code is built as a module, unwind_stack() as used by the
oprofile backtrace code is not available, causing build breakage.
