Assertion in pcpu_init

[Marc Loerner]

Hello Marcel + list,
I tried to boot up the new 8.0-RELEASE disc1 iso and ran into assertion
in pcpu_init (cpuid < MAXCPU).
On my machine/kernel I have 2x4 cores and MAXCPU is set to 4,
so on probing processors in ia64_probe_sapics in madt.c cpu_mp_add gets
called more than MAXCPU-times. This leading to smp_cpus and cpuid in call
of pcpu_init being greater than MAXCPU => Assertion

So solution would be either to modify MAXCPU and compile my own kernel
or adding check on this in cpu_mp_add before calling pcpu_init.

BTW, is there a way to modify MAXCPU dynamically on boot?

Regards,
Marc
