smp_call_init_cpu() is broken in various ways, and I'm about to kill
it, sorry for the inconvenient. I'm finishing tests of the replacement
in my tree now (and already pushed it to 2.5).
However, I'm replacing it with some cleaner assembly code that still
has to access the kernel memory. secondary_start has to be called
with MSR:DR=0 and kernel at it' linked location (but the later shouldn't
be a problem, and clearing MSR:DR neither).
I'll push the new code today
Ben.
