[PATCH] lockdep: i386 remove multi entry backtraces
Remove CONFIG_STACK_BACKTRACE_COLS.
This feature didnt work out: instead of making kernel debugging more
efficient, it produces much harder to read stacktraces! Check out this trace
for example:

That backtrace could have been printed much nicer as a one-entry-per-line
thing, taking the same amount of screen real-estate.
Plus we remove 30 lines of kernel code as well.
