the first time block 0 is read. This fix initialises the block
numbers to -1 which isn't the most correct thing for a daddr_t but
it isn't likely to cause a problem in the boot blocks and it could
do with a more thought out fix later.
The bug is probably benign on the i386 but on the alpha it can
cause initial file opens to fail. This is the cause of the "can't
open /boot/boot.conf" errors.
It appears on the alpha because of a number of combining factors.
On the alpha the LABELSECTOR is 0 so block 0 needs to be read in
from the media. The first time this happens you get a false hit
because the bc_blkno field is zero initially. Also, the timestamp
check against this cache hit succeeds because on the alpha a hacked
getsecs() function can return 0 when it starts counting so that
the zero initial timestamp + BCACHE_TIMEOUT is greater than the
current time until getsecs() has counted passed BCACHE_TIMEOUT.
The overall effect is that the first open() that occurs gets a
false cache hit and returns garbage to the bd_strategy() function
which then fails the open() call. This false hit then stays in the
cache until BCACHE_TIMEOUT getsecs() ticks have passed; all open()
calls during this time fail.
This explains why you can generally access the media by the time
you get to interp() and start issuing commands but the earlier
attempts to run the boot scripts are failing.
It's possible that this is causing the problem switching to the
mfsroot floppy as well but I haven't confirmed that.
almost always causes this panic for the curproc != pageproc case.
This case apparently doesn't happen in normal operation, but it
happens when vm_page_alloc_contig() is called when there is a memory
hogging application that hasn't already been paged out.

This commit fixes the PCI vendor/device ID for this device

I also changed the transmit encapsulation routine to always to

anyway. I also tweaked the code that pads packets out to the minimum

m_len. I don't think this makes that much difference in the grand
scheme of things, but it makes me feel better.

/dev/zero doesn't support mmap(), but the device driver mmap routines are

Build the ordered list of libraries in a variable "_libs" before
building any of them. This eliminates a little bit of duplicated
code. More importantly, it makes it easier to include or exclude
libraries with .if constructs, because the list can be built in
multiple steps using "+=".

modules for FreeBSD's standard authentication methods. Although
the Linux-PAM modules are present in the contrib tree, we don't
use any of them.
The main library "libpam" is composed of sources taken from three
places. First are the standard Linux-PAM libpam sources from the
contrib tree. Second are the Linux-PAM "libpam_misc" sources, also
from the contrib tree. In Linux these form a separate library.
But as Mike Smith pointed out to me, that seems pointless, so I
have combined them into the libpam library. Third are some additional
sources from the "src/lib/libpam" tree with some common functions
that make it easier to write modules. Those I wrote myself.
