a75528de6b Clean up some code having to do with the 398X cards. We can't rely on the
7810 being either the last of the first device to be probed, so use a counting
scheme instead to determine when one card ends and another begins.  There may
be a better way to do this by decoding the PCI tag, which I will investigate
later.

2.2 Candidate.

bf850955ed Move the include opt_aic7xxx in aic7xxx.h so that all of the driver files get
it automatically.  The AHC_FORCE_PIO option wasn't having any effect because
the PCI probe code didn't include this file.

Fix some problems with the new sync and wide negotiation code.  First off,
go back to async transfers by using a message reject again.  The SCSI II and
III spec indicate that if a target's response to an initiater does not suit
(i.e. its too low), then performing a message reject is the appropriate
response.  If, on the other hand, the initiator begins the negotiation and
we want to go async, we will send back an SDTR message with a 0 period and
offset.

Also fix a really bad negotiation problem caused by a missing "break".  This
would usually hit people that had "smart" wide devices that immediately
attempt sync negotiation after a successful wide negotiation.

2.2 Candidate.

775395aaac index_untagged_scb should rely solely on the argument passed in SINDEX and
not access SCB_TCL directly.  This could have caused problems on twin channel

0a9d630ea8 Protect against PCI devices which may have their 'changed' flag set,

isa_device structure attached to them.

db2c0faa4c Vastly improved contigmalloc routine. It does not solve the
problem of allocating contiguous buffer memory in general, but
make it much more likely to work at boot-up time.  The best
chance for an LKM-type load of a sound driver is immediately
after the mount of the root filesystem.

This appears to work for a 64K allocation on an 8MB system.

b3ac88f13f New vx driver for:
3COM 3C590 Etherlink III PCI,
        3COM 3C595 Fast Etherlink PCI,
        3COM 3C592 Etherlink III EISA,
        3COM 3C590 Fast Etherlink EISA,
        3COM 3C900 Etherlink XL PCI and
        3COM 3C905 Fast Etherlink XL PCI.

This driver is based on OpenBSD's driver. I modified it to run under FreeBSd
and made it actually work usefully.
Afterwards, nao@tom-yam.or.jp (HAMADA Naoki) added EISA support as well as
early support for 3C900 Etherlink XL PCI and 3C905 Fast Etherlink XL PCI.
He also split up the driver in a bus independant and bus dependant parts.

Especially the 3c59X support should be pretty stable now.

206e5b7e27 Fixed some races and misleading comments in ufs_rename().
1. When a directory is renamed to an existing (empty) directory,
it is possible for the target vnode to become the source vnode
underneath you (because another process may complete the same
rename).  It was assumed that this can't happen, and the bogus
errno EINVAL was returned.  This was fairly harmless.

Fix: return ENOENT instead, as if the source directory was renamed
a little earlier.

2. The same metamorphosis is possible for non-directories.  It was
assumed that this can't happen, and the code for handling "just
removing a link name" happened to be used.  This would have worked
except for fatal bugs in the link name removal - the link name was
assumed to still be there, and a null pointer was followed.

Fix: check the result of relookup().  This fixes PR 1930.

Notes:

(a) POSIX seems to say that removing link names shall have no effect.
BSD (4.4Lite2 at least) does something reasonable instead.

(b) The relookup() may find a file unrelated to the original.
Removing this isn't correct.  Consider 3 existing files A, B and
C, and concurrent renames: AB = rename(A, B), another AB, and
CA = rename("c", "a").  If rename() is atomic, then only the
following results are possible:

	AB, AB (fails), CA: A = original C, B = original A, C = gone
	AB, CA, AB:         A = gone,       B = original C, C = gone
	CA, AB, AB (fails): A = gone,       B = original C, C = gone

but ufs_rename() can give:

	A,AB,CA,B (sorta):  A = gone,       B = original A, C = gone

This usually doesn't matter, since getting into a race is usually
an error.

These fixes should be in 2.1.6 and 2.2.

5c2a644a47 Fix a problem with running down processes that have left wired
mappings with mlock.  This problem only occurred because of the
quick unmap code not respecting the wired-ness of pages in the
process.  In the future, we need to eliminate the dependency
intrinsic to the design of the code that wired pages actually
be mapped.  It is kind-of bogus not to have wired pages mapped,
but it is also a weakness for the code to fall flat because
of a missing page.

This show fix a problem that Tor Egge has been having, and also
should be included into 2.2-RELEASE.

4441bd4c1b Avoid touching the LEDs too early in the game. After the recent
changes to the keyboard code in pcvt, this update_led() very often
caused pcvt to hang early at boot time.

(Eventually, a better solution should be found, but the simple
omission serves well as a workaround for something that is actually a
show-stopper class problem.)

AHC_SHARE_SCBS - This option attempts to share the external SCB SRAM on
	the 398X controllers allowing a totoll of 255 non-paged SCBs.
