I've just got to finish the GNU Mach compilation, patched to add SMP

Yes, I found their definitions in *linux/dev/arch
Using grep, I've found *local_bh_count* and *local_irq_count. ffs *is

But I don't find the *intel_startCPU* definition. In

We have fixed many little errors and now have just found another big

I'm trying to define the cpu_number() in multiprocessor.
To do this, I tried to use CPUID assembly x86 instruction, to get the CPU
SMP number.
The function, in C, is this:
static inline char smp_processor_id(void) {
char apic_id = 0;
asm("mov $1, %%eax\n\t"
"cpuid\n\t"
"mov %%bh, %0\n\t"
Ok. I understand you. But then... how can I to define cpu_number() function
in multiprocessor? It isn't clear
