1. Leave the RX interrupt routine if there is no mbuf available.
2. Properly initialize and track tx_desc_used_count counter so as not to
leak mbuf while traversing used descriptors.

VFS_VGET() has returned in ufs_lookup(). If the '..' lookup started
immediately before the parent directory was removed, we might return
either cleared or unrelated inode otherwise.
Ufs_lookup() is split into new function ufs_lookup_() that either does
lookup, or verifies that directory entry exists and references supplied
inode number.

naming of the partitions (GEOM_PART_EBR_COMPAT). When
compatibility is enabled, changes to the partitioning are
disallowed.
Remove the device name aliasing added previously to provide
backward compatibility, but which in practice doesn't give
us anything.
Enable compatibility on amd64 and i386.
In the good old days it was possible to have dev_t's that referred to
nonexistent devices. In these cases devtoname() automatically generated
names. This is no longer possible, so remove this dead code.
Discussed with: kib
Remove the `udev' variable, which has a different type than the original
function argument and si_drv0. The `udev' name is also misleading,
because it is not the number returned by dev2udev(). Rename this
argument to `unit'. It is the same number as returned by dev2unit().
We should still access si_drv0 using dev2unit(). Also change the
KASSERT() to really print the udev instead of the unit number. I suspect
it's still useful to print the unit number, especially for devices that
use clone lists, so keep the unit number in the panic string.
- Do not iterate int 15h, function e820h twice. Instead, we use STAILQ to
store each return buffer and copy all at once.
- Export optional extended attributes defined in ACPI 3.0 as separate
metadata. Currently, there are only two bits defined in the specification.
For example, if the descriptor has extended attributes and it is not
enabled, it has to be ignored by OS. We may implement it in the kernel
later if it is necessary and proven correct in reality.
- Check return buffer size strictly as suggested in ACPI 3.0.

- add show as alias for get
- add weights to allow mpath to do more than equal cost
- add sticky / nostick to disable / re-enable per-connection load balancing
This adds a field to rt_metrics_lite so network bits of world will need to be re-built.

- Remove redundant softc members for RIDs.
- Change some softc members to be unsigned where more appropriate.
- Add some missing const.
- Remove support for mmap(2)'ing VGA I/O as it was broken [1] and
not required by X.Org anyway.
- Fix some confusion between bus, physical and virtual addresses
which mostly consisted in using members of struct video_adapter
inappropriately but wasn't fatal except for the regular framebuffer
mmap(2)'ing.
- Remove redundant bzero(9)'ing of the softc.
- Don't map the framebuffer twice in case the firmware has already
mapped it as besides wasting resources this isn't possible with
all MMUs. This is a bit tricky as a) just because the firmware
provides a property with a virtual address doesn't mean it's
actually mapped (but typically is when the framebuffer is the
console) and b) the firmware doesn't necessarily map the it with
the same byteorder as we do. This make machfb(4) work on machines
with cheetah-class MMUs (including X.Org).

addresses to BARs into new pci_read_bar() and pci_write_bar() routines.
pci_add_map(), pci_alloc_map(), and pci_delete_resource() now use these
routines to work with BARs.
- Just pass the device_t for the new PCI device to various routines instead
of passing the device, bus, slot, and function.
