a3dbba7a60 Yves has sent us a ~600 Kb patch, which shuts up gcc entirely for the 
entire kernel.
Unfortunately we didn't send him a copy of the style guide before he did it.
I'm trying to find all the benign and downright sound bits and will commit
them without any other explanation than "YF fix" if they are merely cosmetic.

9e5c18f7b1 The following patches are for the sound drivers. These changes will 
add a an ioctl call to set the transfer block size (SNDCTL_DSP_SETBLKSIZE)
and add the select system call to the drivers.  They also fix a problem with
the #EXCLUDE macros for the PAS-16 card.

2655f62632 In sync(), don't dereference the proc pointer if it's NULL. Should fix 
most or all of the problems with calling sync() without a curproc (which
can happen in machdep.c during a panic sync).

1e3a24e880 Actually access the right first page if the file. 
Bruce finally caught this bogon for me, Thank you Bruce !
Due to some part of the VM/buffer/pmap magic doing clustering, this bogon
managed to work better than 99.9% of the time.  Amazing.
If You ever again see a weird message from the gzip code, please tell me.

911b598f11 1. If some output still present at the end of ttywait, kill it. 
2. Even if ttywait() fails, call ttyflush(FREAD) in ttywflush.
This two fixes guarantee that queues are empty after calling ttywflush()

casting evils and generally neated this file up as much as possible.  It

95b44faffd Turn on "Capture Effect" avoidence. This modifies the collision algorithm 
so that the interface won't have the effect of blocking other senders
during bulk transfers (i.e. hogging the ethernet). It improves performance
in all of my tests by reducing collisions and I believe it to be a Good
Thing.

a0292f2375 Merge Transaction TCP, courtesy of Andras Olah <olah@cs.utwente.nl> and

NB: This has not had David's TCP ACK hack re-integrated.  It is not clear
what the correct solution to this problem is, if any.  If a better solution
doesn't pop up in response to this message, I'll put David's code back in
(or he's welcome to do so himself).
