[PATCH] gcc 3.1 breaks wchan

[Anton Blanchard]

Hi,

I noticed on a ppc64 kernel compiled with gcc 3.1 that context_switch
was left out of line. It ended up outside of the
scheduling_functions_start_here/end_here placeholders which breaks
wchan.

This is one place where we require the code to be inline, so we should use
extern.
