402bcb9621 Fix a problem that could cause msync (or many other things) to deadlock.
The heuristic for managment of memory backing the buffer cache was
nice, but didn't work due to some architectural problems.  Simplify
and improve the algorithm.

ebd707d36a Fixed miscounting for non-statistical (GUPROF) profiling:
- use CROSSJUMP() and CROSSJUMP_LABEL() for conditional jumps from idle()
  into cpu_switch() and vice versa.
- moved badsw code to after cpu_switch().

Cosmetic changes:
- moved sw0 string to be immediately after its caller (badsw).
- removed unused #include.

aad9af2ba3 Removed nested include of <sys/proc.h> from <vm/vm_object.h> and fixed
the one place that depended on it.  wakeup() is now prototyped in
<sys/systm.h> so that it is normally visible.

Added nested include of <sys/queue.h> in <vm/vm_object.h>.  The queue
macros are a more fundamental prerequisite for <vm/vm_object.h> than
the wakeup prototype and previously happened to be included by
namespace pollution from <sys/proc.h> or elsewhere.

64a88efa64 Fixed setting of the keyboard LEDs. For some keyboards and/or keyboard
controllers, it is an error to issue a command before the keyboard
has had time to reply to the previous command.  Setting the LEDs
involves issueing 2 commands, so it never worked on these keyboards.

Fixed resetting of keyboard.  It is possible for unprocessed
scancodes to be present when the reset routine is called.  This
usually occurs after switching from one console driver to another
in userconfig.  pcvt and syscons attempt to flush any stale scancodes,
but sometimes fail to do so because keyboard and/or keyboard
controller takes a long time to send the scancodes after reset
(scancodes are apparently not flushed by reset!).  syscons handles
this later by not checking for errors at strategic places, but pcvt
was confused.

Use an impossible initial and failure mode setting for the LEDs
so that the LEDs always get set if they are possibly out of sync.

Added missing spltty() in update_led().

ccb174975a Fixed lblktosize(). It overflowed at 2G. This bug only affected
ufs_read() and ufs_write().

Found by: looking at warnings for comparing the result of lblktosize()
(which is usually daddr_t = long) with file sizes (which are u_quad_t
for ufs).  File sizes should probably be off_t's to avoid warnings
when the are compared with file offsets, so the fixed lblktosize()
casts to off_t instead of u_quad_t.

Added definition of smalllblksize().  It is the same as the old
lblksize() and is more efficient for small block numbers on 32-bit
machines.

Use smalllblktosize() instead of its expansion in blksize() and
dblksize().  This keeps the line length short and makes it more
obvious that the shift can't overflow.

bdef8bf092 Undo a mistaken change from splhigh to splvm. Subr_rlist has been
capable of being used for things other than swap space allocation,
and splvm would have been appropriate for only swap space allocation
and other VM things.  My commit broke that (and was actually a mistake.)

9d3fbbb5f4 Performance optimizations. One of which was meant to go in before the
previous snap.  Specifically, kern_exit and kern_exec now makes a
call into the pmap module to do a very fast removal of pages from the
address space.  Additionally, the pmap module now updates the PG_MAPPED
and PG_WRITABLE flags.  This is an optional optimization, but helpful
on the X86.

da2186afa3 Cleaned up:
- fixed a sloppy common-style declaration.
- removed an unused macro.
- moved once-used macros to the one file where they are used.
- removed unused forward struct declarations.
- removed __pure.
- declared inline functions as inline in their prototype as well
  as in theire definition (gcc unfortunately allows the prototype
  to be inconsistent).
- staticized.

8ba0c490a9 Removed __pure's and __pure2's. __pure is a no-op for recent versions
of gcc by definition, and __pure2 is a no-op in effect (presumably the
compiler can see when an inline function has no side effects).

4458ac71b1 Removed nested include if <sys/socket.h> from <net/if.h> and

include just allowed unportable programs to compile and made my
simple #include checking program report that networking code doesn't
need to include <sys/socket.h>.

20bc4c3ac1 Improve support of SCSI cards based on the 53c860 and 53c875.
Still no support for Ultra-SCSI and other new features, but the code
should now correctly initialize the clock pre-scaler (based on freqency
measurement results, if necessary).

Fix support of 16 targets for WIDE SCSI.

Disable bus reset in case no progress is made for too long ("ncr dead"
message), which did not work too well with scanners and other slow devices.

did (tail drop's the syns) pending discussion with fenner about some socket
state flags that I don't fully understand.
