67931eee29 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. (!)

a3cc211552 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.

6b740ac6e9 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

eac7371c68 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.

d12b1628ed 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.

e20b650550 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.

8fad3d6dbc 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 ?
