Yes, but your patch never applied to anything even remotely looking like the code in my tree. I got so frustrated that I ended up reimplementing it in a cleaner way. Now head.S calls i386_start_kernel() and that calls pda_init() without any additional assembly code or other special cases etc. This is very similar to how x86-64 works. > which means that that they > have to work from the first function prologue. I mainly did it to fix lockdep. I used to do mcount hacks myself, but you typically need a few special annotations for those anyways so I am not too concerned about them. > It also simplifies things to get all that set up ASAP so there's no > bootstrap dependency problem. Yes no argument on that. -Andi
