Garbage-collect the VM_MBUF_SIZE constant. Instead, use the size
...
(nmbclusters * mclbytes), so that the right amount of KVA space is
allocated if those variables are patched.

this is the i386 MD portion of the MACHINE_NEW_NONCONTIG code, as
...
written by chuck cranor. thanks to mycroft for helping me find the
one little line of code i accidentally deleted while merging it.
this is not enabled by default. `options MACHINE_NEW_NONCONTIG'
will use this code. eventually, this should go into <machine/vmparam.h>
insteaed of MACHINE_NONCONTIG.

bump MAXSSIZ back down to 8M (from 256M, where charles put it).
...
execve() currently allocated MAXSSIZ of address space (AND PAGE TABLES)
for the stack. until that's changed, and the stack-handling code is
updated to match, MAXSSIZ==256M will make execve() significantly slower
than MAXSSIZ==8M.
