Maybe it makes sense to define a MACHINE_ARCH32 in machine/param.h, as
is done for ELF_ARCH32 in machine/elf.h? This would keep the MI code in
the kernel MI, and ever-so-slightly simplify implementation for ia64,
mips, and powerpc64. Thanks for doing this!

I intend to commit the following change, that makes sysctls

print "i386", that is good for i386 jails on amd64 kernels.
I find the change very useful for me, but I wonder why such trivial
modification is not yet done. Can anybody note a possible fallout from
Presumably ia64 and powerpc64 would need a similar change as well? It looks
fine to me. I suspect Y! used the UNAME_* approach as it didn't add yet-
another local diff to maintain in the kernel, and the uname fixes at Y! might
have predated SCTL_MASK32.
