It seems to me, that this argument is becoming about "you said these and

To me,then, this is not about me or you, what I said and what you said;
this is about what Ubunto
does as far as SMP is concerned.
You are saying that the previous posts are about what Ubunto does when
implementing UP.
So, what about what Ubunto does when it implements SMP ?
From Jeff's post:
1) Ubuntu currently ships and supports separate packages for UP and SMP
kernels
Is there something more to the question than that? They have the normal
kernel
source and compile it twice, once UP, once SMP. It then ships a package
for each
of these.
Or is the question about how the Linux *kernel* implement SMP?
It was shown what spinlock is for UP.
What is spinlock for SMP ?
<sigh>
So you are asking how the Linux *kernel* implements SMP. This has nothing
to do with Ubuntu.
I'm sure you can look this up in the kernel code yourself. The place to
start looking is in include/linux/spinlock.h, and include/asm-i386/spinlock.h
It isn't really worth spamming the whole list with the obtuse x86 assembler.
Ummmmmmmmm. I'll figure.
