7d20bafcad Generate top.local.h and manpage dynamically, with sed(1) script.
The generated manpage will now describe the actual behavior of
top(1) WRT how many processes it displays.  This also eliminates
all troff(1) warnings.

9e13809564 Fix top(1) display for SMP systems where the username is longer than 14
characters.  This should avoid unattractive wrapping for people who are
stuck in an 80x24 screen.  :-)

98e53e5bfb - An array of 4 32-bit ints for avenrun doesn't work on the alpha because
fscale is a (64-bit) long.  So just use a struct loadavg.
This fixes the recent failure of top on alphas:
	top: sysctl(vm.loadavg...) failed: Cannot allocate memory

- use size_t for sizeof() so as to fix a few int/long warnings on alpha

1f7d250182 Change the proc information returned from the kernel so that it
no longer contains kernel specific data structures, but rather
only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and
top would all stop working. The new structure has over 200 bytes
of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.

0384fff8c5 Major update to the way synchronization is done in the kernel. Highlights
include:

* Mutual exclusion is used instead of spl*().  See mutex(9).  (Note: The
  alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
  preempted (i386 only).

dc7c1750c2 Reduce max length of user names to 15 characters to reflect reality.
This also prevents the line-wrap and messed up display that occurs
when there happens to be one or more names with 15 chars.

a8224b82fd Fixed sorting on time. On i386's, time differences of more than 2147
seconds caused overflow.  Use a type-safe but slightly slower comparison.
Comparisons for other fields are still fragile.

Fixed rounding of cputime (don't do extra work to get it slightly wrong
by first converting without rounding to milliseconds).

Removed dead code for setting cputime.

Fixed comments about cputime.

efc96764e0 The magic "no-cpu" cpu number is 0xff. Don't misrepresent cpu
numbers as chars or use bogus casts in an attempt to unmisrepresnt
them.  In top, don't assume that 0xff is the only negative cpu
number when cpu numbers are (mis)represented.

1005b43609 Don't dump core when p_stat is not in the expected range. This is
only likely to happen when you have a kernel<>userland mismatch,
but it's really annoying when top dumps core and leaves the terminal
in a mangled state; it's much nicer to print nicely formatted gibberish.

c13e5fb799 Removed unused nlist'ed variables stathz and hz. These used to be used
to half compensate for broken scaling of p_pctcpu in the kernel, but the
previous commit removed this compensation.  %cpu values will be wrong by
a factor of stathz/hz until the kernel is fixed.  (The kernel gets it
wrong by a factor of stathz/hz, and top got the compensation wrong by
a factor of 100/stathz.)

e796e00de3 Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.
Clean up (or if antipodic: down) some of the msgbuf stuff.

Use an inline function rather than a macro for timecounter delta.

Maintain process "on-cpu" time as 64 bits of microseconds to avoid
needless second rollover overhead.

Avoid calling microuptime the second time in mi_switch() if we do
not pass through _idle in cpu_switch()

This should reduce our context-switch overhead a bit, in particular
on pre-P5 and SMP systems.

WARNING:  Programs which muck about with struct proc in userland
will have to be fixed.
