Phew, it's done. And the winner is: x86_64-mm-i386-stacktrace-unwinder.patch --------8<--------8<--------8<--------8<--------8<--------8<-------- 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. Cc: mingo@elte.hu Signed-off-by: Andi Kleen -------->8-------->8-------->8-------->8-------->8-------->8-------- 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 Linux gx110 2.6.18-mm1-noinitrd #2 PREEMPT Thu Sep 28 18:48:32 CEST 2006 = i686 i686 i386 GNU/Linux machine.
