we get the resource allocation stuff hammered out.
Fix and off by one error that caused unnecessary filtering of valid
BARs for only 4 bytes than ICH3 and other PCI IDE controllers have.
Andrew Gallatin submitted this, although it doesn't solve the problems
ICH3 controllers have with the new code, it does restore the former
resource list on the probe line.
move its declaration to the machine-dependent header file on those
machines that use it. In principle, only i386 should have it.
Alpha and AMD64 should use their direct virtual-to-physical mapping.
- Remove pmap_kenter_temporary() from ia64. It is unused. Approved

The VIA Nehemias is so obviously specific to i386 that it should not
be compiled on non-i386 platforms. The obviousness is in the fact that
all functions in nehemias.c are purely i386 inline assembly, guarded
by #ifdef __i386__

confusing some people. Eventually, these messages will be parked
behind a if (bootverbose).
# I don't think this will fix any real bugs...
Xircom had an unfortunate habit of re-using PCMCIA IDs for quite different
cards - the xe driver knows about this and uses the first byte of 'extra'
PCMCIA ID info to identify cards with ambiguous IDs.

The only hardware source used at this point is the one inside
the VIA C3 Nehemiah (Stepping 3 and above) CPU. More sources will
be added in due course. Contributions welcome!
o Save and restore bars for suspend/resume as well as for D3->D0
transitions.
o preallocate resources that the PCI devices use to avoid resource
conflicts
o lazy allocation of resources not allocated by the BIOS.
o set unattached drivers to state D3. Set power state to D0

for this (display and memory devices) that need work in other
areas of the tree.

megabytes of largely wasted KVA are returned to the kernel map for use
elsewhere.
side effect of that change caused headers to not be sent if a 0 byte
file was passed to sendfile. This change fixes that behavior, allowing
sendfile to send out the headers even with a 0 byte file again.

already may have been destroyed. In that case we would end up
dereferencing a NULL pointer, so specifically test for that as well.

only be initialized if BUS_GET_RESOURCE_LIST() succeeded; it needs to
be initialized unconditionally so that the list cleanup code won't
trip over potential stack garbage.
