Fwd: port-sparc/38288

[Michael Lorenz <macallan%netbsd.org@localhost>]

Hello,

NetBSD/sparc SMP kernels crash shortly after startup because in the  
New Order Of Things(tm) we need to have working CPU_INFO_ITERATOR and  
friends before autoconf runs. On sparc this fails because struct  
cpuinfo **cpus isn't allocated before the 1st CPU attaches so cpus is  
NULL when percpu_backend_alloc() runs.

So, this leaves the question how much we care about sun4d support  
since sun4m is effectively limited to 4 CPUs and allocating four  
struct cpuinfo statically, even page-aligned, isn't that much of a  
waste.

have fun
Michael
