Question about fixing kallsyms, which I would like done too. I guess an
invisible place holder for weak functions may be best. Saving the size of
all functions could be memory wasteful. As there are a lot of functions:

 # wc -l /proc/kallsyms 
 207126 /proc/kallsyms

What would be best? To add a placeholder where weak functions are, but they
would not be printed in /proc/kallsyms?  If a lookup occurs, and it lands
on one of theses functions, to return "not found"?
