Where possible, pass size of file to vnode_create_vobject() rather
than having it find it out the hard way via VOP_LOOKUP

Add minor2unit() in addition to dev2unit() and unit2minor().
If it wasn't such a hazzle we should redefine minor numbers in
the kernel without the gap for the major number, but it's not worth
the bother (yet).
a process return to userspace if it had pending GEOM events.
We need to have the same check in the exit pass to catch the case
where a GEOM related filedescriptor is not explicitly closed by
the process.

thought. I'm unsure why I thought this was the case, but it
definitely isn't for this card. If another card with the other ID
makes an appearance, then we'll add a second entry for it.

- Remove all:. It's redundant, and ${LIB} in it is just a bug.
- Remove .ORDER:. *.mgc files can safely be built in parallel.
- Remove PITA. The mkmagic tool is smart to put the binary file
into the current directory (${.OBJDIR}) even if the source file
lives somewhere else, which is just what we need.
EtherJet, the interrupt is selected in the eeprom based on the layout
of the PC Card board. Since this is encoded into the EEPROM, and has
no relationship to the IRQ that the pccard bridge routes the PC Card's
interrupt pin to.
As such, stop writing to that register. This gets my EtherJet working.
# The eeprom reading code appears to be totally wrong for my EtherJet
# card. This causes the card to bogusly detect the media options
# available.
significant clean up and optimizations:
- don't call bioq_disksort() on every command, the hardware will do that for
us.
- remove all of the complicated bio deferral code. bio's that can't be
serviced immediately can just wait on the bioq.
- Only reserve one command object for doing control commands to the card.
This simplifies a lot of code and significantly reduces the size of the
command struct.
- Allocate commands out of a slab instead of embedding them into the softc.
- Call the command action method directly instead of having ips_get_free_cmd()
call it indirectly.

and as long as we're not compiling with IPA, gcc(1) won't optimize
the call away. The whole purpose of using memcpy(3) is to avoid
misaligned loads and stores when we need to read or write the value
in the unaligned memory location. But if gcc(1) optimizes the call
to memcpy(3) away, it will typically introduce misaligned loads and
stores. In this context that's not a good idea.
