for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Remove some pointless inclusions os sys/user.h

Use UPAGES in preferences to USPACE.

eliminate non-literal format strings.

Remove uarea swap-out functionality:

- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Discussed on <tech-kern>, reviewed by <ad>.

- - add new RLIMIT_AS (aka RLIMIT_VMEM) resource that limits the total
address space available to processes.  this limit exists in most other
modern unix variants, and like most of them, our defaults are unlimited.
remove the old mmap / rlimit.datasize hack.
- - adds the VMCMD_STACK flag to all the stack-creation vmcmd callers.
it is currently unused, but was added a few years ago.
- - add a pair of new process size values to kinfo_proc2{}. one is the
total size of the process memory map, and the other is the total size
adjusted for unused stack space (since most processes have a lot of
this...)
- - patch sh, and csh to notice RLIMIT_AS.  (in some cases, the alias
RLIMIT_VMEM was already present and used if availble.)
- - patch ps, top and systat to notice the new k_vm_vsize member of
kinfo_proc2{}.
- - update irix, svr4, svr4_32, linux and osf1 emulations to support
this information.  (freebsd could be done, but that it's best left
as part of the full-update of compat/freebsd.)
this addresses PR 7897.  it also gives correct memory usage values,
which have never been entirely correct (since mmap), and have been
very incorrect since jemalloc() was enabled.
tested on i386 and sparc64, build tested on several other platforms.
thanks to many folks for feedback and testing but most espcially
chuq and yamt for critical suggestions that lead to this patch not
having a special ugliness i wasn't happy with anyway :-)

cast for tdev.

Revert the changes done after newlock2 merge, except for the removal of
the now unused LSDEAD state. The current kernel headers are now
source-compatible with pre-newlock2 kernel headers again.

Approved by Andrew Doran.

interrupt with two rs.

Minimal changes needed to build in an LWP'ified universe.

file ps.c was added on branch nathanw_sa on 2002-05-04 18:53:05 +0000

Use kinfo_proc2.

Fetch maxslp from the kernel.  Only use USPACE if it's defined.

__CONCAT does token pasting, not string concatnation.  if something like:
        __CONCAT("foo","bar");
actually works to concantate strings, it's because the preprocessor expands
it into "foo""bar" as separate strings, and then ANSI string concatenation
is performed on that.  It's more straightforward to just use ANSI string
concatenation directly, and newer GCCs complain (rightly) about misuse
of token pasting.

Remove extern variables and functions now declared in dkstats.h.
While here, remove 77 (!) unneed #includes.

Pull up the following revisions, approved by releng-1-5:

- ANSIfy.

- __RCSID() police.
- Tweak inet.icmp display visual a little.

Pull up to last week's -current.

* Fix a display buglet: if the process list is exhausted before the window's
  bottom is reached, clear the remaining lines, lest there be stale process
  entries if the process list shrinks.
* Implement a top(1)-like `user' command in the ps display.

TNF copyright -- I will do the paperwork to give these over asap.

Knee-jerk snprintf()-ism.

Backout unintended change

Add a file missed in last commit

More fallout from CL* purge.

Pull up revision 1.6 (requested by mrg):
  Fix "dty" vs "tty" problems that have existed since "dty"s were
  invented sometime before 1.4 was released.

recognise "dty" the same as we do "tty"

According to the previous commit the new process state should be SDEAD and
not SDYING, so s/SDYING/SDEAD/.

Update for SDEAD.

Fix CPU percentage of "systat ps".
Yes, the name of the member "pt_pctcpu" is confusing :-).
Use double instead of float.

Add an __RCSID.

Add a new `ps' view to systat, which shows process information.  This
view is identical to the output of `ps aux' except that a.) the RSS and VSZ
fields are one character wider and b.) it shows a zero value for the RSS
and %MEM columns of processes which report a negative RSS.
