[Qemu-devel] [patch] move MAX_CPUS to cpu.h

[Jes Sorensen]

Hi,

In order to allow for other structs to be sized based on MAX_CPUS
and get rid of some ifdef clutter, I'd like to suggest this patch.

Cheers,
Jes

Move definition of MAX_CPUS from vl.c to architecture specific cpu.h
header file. This reduces #ifdef clutter and allows for other files
to define array sizes based on MAX_CPUS, which is needed for KVM and
probably other places.
