    [PATCH] make kstack_depth_to_print and some APM stuff static · 12ae4bff
    Stephen Rothwell authored
    Tridge has written a little utility
    (http://samba.org/ftp/unpacked/junkcode/findstatic.pl) that (given a set of
    object files) works out a list of candidate finctions and variables that
    may be able to be made static.  Obviously some hand checking is needed
    (different configs and/or architectures etc), but it seems useful.
    
    Here is my first patch using its outout.
    
    kstack_depth_to_print is used in many architectures, but only in one
    file in each.  In some architectures it is declared and not used.  It
    is not even clear why kstack_depth_to_print is not a #define.  Tridge
    suggested that maybe you could change its value with a debugger ...
    
    The APM code has a function and a struct that can be static.
