a new resource limit that covers a process's entire VM space, including
mmap()'d space.
(Part II will be additional code to check RLIMIT_VMEM during exec() but it
needs more fleshing out).

64-bit file sizes. This step simply addresses the remaining overflows,
and does attempt to optimise performance. The details are:
o Use a 64-bit type for the vm_object `size' and the size argument
to vm_object_allocate().
o Use the correct type for index variables in dev_pager_getpages(),
vm_object_page_clean() and vm_object_page_remove().
o Avoid an overflow in the i386 pmap_object_init_pt().
the indirection operator ('*') and address examination ('x/a') on
big-endian platoforms for which the above is not true, as well as on
little-endian platforms if the cut-off bits are not 0.
installed with pmap_kenter_flags, since the physical addresses may not
have an associated vm_page. Add a function to do this.

up when operating in PCI-X mode. For some received packets there is
data corruption in the first few bytes in that case. Aligning the
packet buffer eliminates the corruption. With this fix, the code
that offsets the packet buffer up by 2 bytes to align the payload is
disabled for BCM5701s operating in PCI-X mode. On the i386, which
permits unaligned accesses, the payload is left unaligned. On other
platforms, the packet is copied after reception to force alignment
of the payload. Obviously, this work-around reduces performance in
those cases (BCM5701 plus PCI-X) where it is in effect.

sysctl (machdep.cpu_idle_hlt) to off in the SMP case. This allows you to
turn it on if you wish and do not particularly care about the small window
where a cpu will remain halted even when a job is placed on the run queue
(until the next clock tick).
obtained, when all other scheduling activity is suspended. This is needed
on sparc64 to deactivate the vmspace of the exiting process on all cpus.
Otherwise if another unrelated process gets the exact same vmspace structure
allocated to it (same address), its address space will not be activated
properly. This seems to fix some spontaneous signal 11 problems with smp
on sparc64.
otherwise we might get interrupts and are unable to
handle them properly, which results in a page fault.

This fixes a warning on sparc64.

the side of caution until I can figure out what is going on. This
backs out all but the PCI, PCIB and ISA bus interfaces being
"standard," which have been well tested...
