enumerates all the BARs. Without this change, the PCI bus driver would
attempt to initialize a BAR that was already allocated resulting in a panic.
handling for the PCIR_BIOS decoding enable bit from the cardbus driver.
The PCIR_BIOS BAR does include type bits like other BARs. Instead, it is
always a 32-bit non-prefetchable memory BAR where the low bit is used as a
flag to enable decoding.

- Fix bus_generic_rl_(alloc|release)_resource() to not attempt to fetch a
resource list for grandchild devices, but just pass those requests up to
the parent directly. This worked by accident previously, but it is
better to not let bus drivers try to operate on devices they do not
manage.
o Optimize for memory mapped I/O by making all I/O port acceses function
calls and marking the test for the IA64_BUS_SPACE_IO tag with
__predict_false(). Implement the I/O port access functions in a new
file, called bus_machdep.c.
o Change the bus_space_handle_t for memory mapped I/O to the virtual
address rather than the physical address. This eliminates the PA->VA
translation for every I/O access. The handle for I/O port access is
still the port number.
o Move inb(), outb(), inw(), outw(), inl(), outl(), and their string
variants from cpufunc.h and define them in bus.h. On ia64 these are
not CPU functions at all. In bus.h they are merely aliases for the
new I/O port access functions defined in bus_machdep.h.
o Handle the ACPI resource bug in nexus_set_resource(). There we can
do it once so that we don't have to worry about it whenever we need
to write to an I/O port that is really a memory mapped address.
The upshot of this change is that the KBI is better defined and that I/O
port access always involves a function call, allowing us to change the
actual implementation without breaking the KBI. For memory mapped I/O the
virtual address is abstracted, so that we can change the VA->PA mapping
in the kernel without causing an KBI breakage. The exception at this time
is for bus_space_map() and bus_space_unmap().

* Faster handling of the internal file lists.
* Better detection of ISO variants
grant table API. Valid grant refs are in the range of positive 32bit
integers. ENOSPACE, being 29, is also a positive integer. Return
GNTTAB_LIST_END (-1) instead when gnttab_claim_grant_reference() fails.
I was considering committing all these patches one by one, but as
discussed with brooks@, there is no need to do this. If we ever
need/want to merge these changes back, it is still possible to do this
per application.
This replaces d_mmap() with the d_mmap2() implementation and also
changes the type of offset to vm_ooffset_t.
Purge d_mmap2().
All driver modules will need to be rebuilt since D_VERSION is also
bumped.

wlan(4) interfaces. vlan(4) interfaces are listed via a new 'vlans_<IF>'
variable. If a vlan interface is a number, then that number is treated as
the vlan tag for the interface and the interface will be named '<IF>.<tag>'.
Otherwise, the vlan tag must be provided via a vlan parameter in a
'create_args_<vlan>' variable.
While I'm here, fix a few nits in rc.conf(5) and mention create_args_<IF> in
the description of cloned_interfaces.

renamed. Previously the vlan interfaces would lose their configuration as if
the parent interface had been physically removed. Now vlan interfaces ignore
rename events.
- Add a new ifnet flag (IFF_RENAMING) that is set while an ifnet is being
renamed. This flag can be checked in ifnet departure/arrival event
handlers to treat rename events differently.
- Change the ifnet departure event handler in the if_vlan(4) driver to
ignore departure events due to a trunk interface being renamed.

Because strings are now null-terminated, I've decided to just use an
array of utmpx structures, instead of the separated strings. This means
we just copy the entire utmpx structure and point to the strings within
the structures directly.
