dbb315cb8e Gag! Somebody removed the bus mouse from GENERIC for reasons unknown. 
That certainly explains why I noticed it suddenly missing from the
2.2 SNAPSHOT! :-)

d78a37ad5a Logging UDP and TCP connection attempts should not be enabled by default. 
It's trivial to create a denial of service attack on a box so enabled.

These messages, if enabled at all, must be rate-limited. (!)

d3a3498598 Reinstitute the map lock for processes being swapped out. This 
is needed because of the vm_fault used to bring the page table page
for the kernel stack (UPAGES) back in.  The consequence of the
previous incorrect change was a system hang.

c755a8837c Added isa_dmadone() to fix the errors the sound driver has been complaining 
about.

1dce4e5d60 Add a lock for DMA Channels to prevent two devices from using the same DMA 
channel at the same time.  The functions isa_dma_acquire() and
isa_dma_release() should be used in all ISA drivers which call isa_dmastart().
This can be used more generally to register the usage of DMA channels in
any driver, but it is required for drivers using isa_dmastart() and friends.

Clean up sanity checks, error messages, etc.
Remove isa_dmadone_nobounce(), it is no longer needed

b5cfb15fad Map lock checks not needed anymore for swapping out. We don't use 
map operations for it anymore.  Certain deadlocks should never happen
anymore.

0166c5c6b4 Allow specifying the BIOS drive number. Removed the hd drive type. 
hd essentially wired the FreeBSD drive number to 0 without changing
the BIOS drive number.  Now the numbers can be specified independently.

Replaced the BOOT_HD compile time flag with with BOOT_HD_BIAS.  Defining
the new flag as 1 should give the same behaviour as defining the old
flag as anything.  I haven't tested defining these flags.

c655b7c4f4 Added proper splnet protection while modifying the interface address list. 
This fixes a panic that occurs when ifconfig ioctl(s) were interrupted
by IP traffic at the wrong time - resulting in a NULL pointer dereference.
This was originally noticed on a FreeBSD 1.0 system, but the problem still
exists in current sources.

c80faa792c Work around a braindead signal handling in many newer HP printers. 
They don't have BUSY de-asserted by the time they ACK (and thus cause
an interrupt).  The workaround is to try seeing if the BUSY will be
de-asserted soon, and if not, to use an incremental backoff and
semi-polled mode instead of the fixed timeout with 1/2 s we've been
using previously (that caused the printer to run really slooow).

Printers that have been working previously should not be affected by
this.

34be9bf3ce Add a sysctl (net.inet.tcp.always_keepalive: 0) that when set will force 
keepalive on all tcp sessions.  Setsockopt(2) cannot override this setting.
Maybe another one is needed that just changes the default for SO_KEEPALIVE ?
