3398edcee9 Revert previous commit. Remove all ifp->if_* = 0 initializations,
since pkh made tunctl static in revision 1.17 these are already
guaranteed to be zero'd and tunattach will only be called once.

158f45f157 Add a new ioctl, SCSIOCGETDEVINFO, which takes a device ID and uses it
to look up information about that device.  Right now, all it does
is give back the dev_t for the device, if known, since that's all
I needed, but hopefully the SCSI mavens will come up with a more generally
useful structure.

c15541e7a7 contigalloc doesn't place the allocated page(s) into an object, and
now this breaks vm_page_wire (due to wired page accounting per object.)

This should fix a problem as described by Donald Maddox.

eaf13dd73a Change the busy page mgmt, so that when pages are freed, they
MUST be PG_BUSY.  It is bogus to free a page that isn't busy,
because it is in a state of being "unavailable" when being
freed.  The additional advantage is that the page_remove code
has a better cross-check that the page should be busy and
unavailable for other use.  There were some minor problems
with the collapse code, and this plugs those subtile "holes."

Also, the vfs_bio code wasn't checking correctly for PG_BUSY
pages.  I am going to develop a more consistant scheme for
grabbing pages, busy or otherwise.  For now, we are stuck
with the current morass.

c5b193bfba Retire LFS.
If you want to play with it, you can find the final version of the
code in the repository the tag LFS_RETIREMENT.

If somebody makes LFS work again, adding it back is certainly
desireable, but as it is now nobody seems to care much about it,
and it has suffered considerable bitrot since its somewhat haphazard
integration.

0621c31aaf Make the bounce buffer code a little more robust when space isn't

is disabled.  This will allow most large systems to run properly
when the bounce space is mistakenly allocated above 16MB.

c67d7e8aa2 Fix operation with the Iomega Zip 100 ATAPI.
All known versions of this drive (firmware 21.* and 23.*) will lock up
if presented with a read/write request of > 64 blocks.  In the presence
of such a unit, I/O requests of > 64 blocks are fragmented to avoid
this.

facf6a3fbe Check the status port after waiting for DRQ; some drives seem to be very
slow coming off the bus (eg. Iomega's ATAPI Zip).  Failure to do
this results in a false probe of an ATAPI device with garbage
data.

c3229e05a3 Improved connection establishment performance by doing local port lookups via
a hashed port list. In the new scheme, in_pcblookup() goes away and is
replaced by a new routine, in_pcblookup_local() for doing the local port
check. Note that this implementation is space inefficient in that the PCB
struct is now too large to fit into 128 bytes. I might deal with this in the
future by using the new zone allocator, but I wanted these changes to be
extensively tested in their current form first.

Also:
1) Fixed off-by-one errors in the port lookup loops in in_pcbbind().
2) Got rid of some unneeded rehashing. Adding a new routine, in_pcbinshash()
   to do the initialial hash insertion.
3) Renamed in_pcblookuphash() to in_pcblookup_hash() for easier readability.
4) Added a new routine, in_pcbremlists() to remove the PCB from the various
   hash lists.
5) Added/deleted comments where appropriate.
6) Removed unnecessary splnet() locking. In general, the PCB functions should
   be called at splnet()...there are unfortunately a few exceptions, however.
7) Reorganized a few structs for better cache line behavior.
8) Killed my TCP_ACK_HACK kludge. It may come back in a different form in
   the future, however.

These changes have been tested on wcarchive for more than a month. In tests
done here, connection establishment overhead is reduced by more than 50
times, thus getting rid of one of the major networking scalability problems.

Still to do: make tcp_fastimo/tcp_slowtimo scale well for systems with a
large number of connections. tcp_fastimo is easy; tcp_slowtimo is difficult.

WARNING: Anything that knows about inpcb and tcpcb structs will have to be
         recompiled; at the very least, this includes netstat(1).
