4011fcfefd Cache the "adjusted" value of sb_max when sb_max is changed, in order
to avoid doing quad math in sbreserve().

Change suggested by Simon Burge, and code inspired by a similar change
in FreeBSD.

e43fd45f1a Make SHMSEG much larger to accomodate GNOME and imlib.
It's limited by SHMMAXPGS anyway.

dd06794f0b Remove shmsegs declaration from conf/param.c - it doesn't belong here.
Instead, put it in kern/sysv_shm.c.

7b918b4088 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

8ce41be7b0 Move inclusion of "opt_sb_max.h" from sys/socketvar.h to
conf/param.c, and move the initialisation of the sb_max
variable from kern/uipc_socket2.c to conf/param.c.  Now
everthing that includes sys/socketvar.h doesn't get
recompiled when SB_MAX's value changes.

9a06d5e2a6 Compute compile-time value of old-VM parameter MAX_KMAPENT from NPROC
(2x NPROC plus slop) unless expclitly set. Use current constant value
(100) as a lower bound, as suggested by Chuck Cranor.

Move NPROC and other parameter definitions from param.c to param.h so
they are visible to vm/vm_map.h.

Systems with hand-tuned NPROC should now support that many processes.

1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

f0f7e53290 Add compiled-in MCLBYTES and MSIZE to conf/param.c, as 'mclbytes" and "msize".
Add code to netstat to use libkvm to for kernel variables "mclbytes"
and "msize', and if found, use those for netstat -m rather than
compiled-in defaults.

b89a3425b7 Eliminate obsolete TIMEZONE and DST options.
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.

3938d6ba02 initialize shmmax to `# of pages' at compile time; multiply by NBPG at
boot time (in shminit). This supports architecture families with varying
values for NBPG, and does not break ipcs.
