    Phew, it's done. And the winner is:

    i386: Do stacktracer conversion too

    Following x86-64 patches. Reuses code from them in fact.

    Convert the standard backtracer to do all output using
    callbacks. Use the x86-64 stack tracer implementation
    that uses these callbacks to implement the stacktrace interface.

    This allows to use the new dwarf2 unwinder for stacktrace
    and get better backtraces.

    Backing out just this patch from 2.6.18-mm1 (and resolving conflicts
    manually the obvious way) gets the boot time back to normal (ie. as
    fast as 2.6.18 mainline) on my
