collected at boot and made available through sysctl(8). At the
moment, the following MIB names are created:
hw.mca.count - The number of error records collected.
hw.mca.first - The lowest sequence number present.
hw.mca.last - The highest sequence number present.
hw.mca.<X> - The error record with sequence number <X>.
Using sysctl(8) allows us to easily detect and analyze the records,
which is very helpful during development of MCA but can also be used
in production as a way to collect machine health statistics.
\ No newline at end of file
line that some versions of diff print out if the last line of the two files
are different, and one of the two files does not have a newline character
on that last line.
This change is still somewhat under discussion in -arch and -standards, but I
want to commit it to -current today so I'd have the chance to MFC it to -stable
before the code freeze for 4.6-release (which would be May 1st).
Note: the related change to 'diff' (so it might *generate* that line) is NOT
expected to be included in 4.6-release. We can debate that change later.

Do not install games and profiled libraries to the ${CHROOTDIR}
with the initial installworld.
Eliminate the need in the second installworld. For that, make sure
_everything_ is built in the "world" environment, using the right
tool chain.
Added SUBDIR_OVERRIDE helper stuff to Makefile.inc1. Split the
buildworld process into stages, and skip some stages when
SUBDIR_OVERRIDE is set (used to build crypto, krb4, and krb5
dists).
Added NO_MAKEDB_RUN knob to Makefile.inc1 to avoid running
makewhatis(1) at the end of installworld (used when making crypto,
krb4, and krb5 dists).
In release/scripts/doFS.sh, ensure that the correct boot blocks are
used.
Moved the creation of the "crypto" dist from release.5 to
release.2.
In release.3 and doMFSKERN, build kernels in the "world"
environment. KERNELS now means "additional" kernels, GENERIC is
always built.
Ensure we build crunched binaries in the "world" environment.
Obfuscate release/Makefile some more (WMAKEENV) to achieve this.
Inline createBOOTMFS target.
Use already built GENERIC kernel modules to augment mfsfd's
/stand/modules. GC doMODULES as such.
Assorted fixes:
Get rid of the "afterdistribute" target by moving the single use
of it from sys/Makefile to etc/Makefile's "distribute".
Makefile.inc1: apparently "etc" no longer needs to be last for
"distribute" to succeed.
gnu/usr.bin/perl/library/Makefile.inc: do not override the
"install" and "distribute" targets, do it the "canonical" way.
release/scripts/{man,cat}pages-make.sh: make sure Perl manpages and
catpages appear in the right dists. Note that because Perl does
not respect the MANBUILDCAT (and NOMAN), this results in a loss of
/usr/share/perl/man/cat* empty directories. This will be fixed
soon.
Turn MAKE_KERBEROS4 into a plain boolean variable (if it is set it
means "make KerberosIV"), as documented in the make.conf(5)
manpage. Most of the userland makefiles did not test it for "YES"
anyway.
XXX Should specialized kerberized libpam versions be included into
the krb4 and krb5 dists? (libpam.a would be incorrect anyway if
both krb4 and krb5 dists were choosen.)
Make sure "games" dist is made before "catpages", otherwise games
catpages settle in the wrong dist.

timeout loop.
Limit the rate at which we wind the timecounters to approx 1000 Hz.
This limits the precision of the get{bin,nano,micro}[up]time(9)
functions to roughly a millisecond.
timecounter will be used starting at the next second, which is
good enough for sysctl purposes. If better adjustment is needed
the NTP PLL should be used.
around. If the kernel boots successfully, the record of this kernel
is erased, it is intended to be a one-shot option for testing
kernels.
This could be improved by having the loader remove the record of
the next kernel to boot, it is currently removed in /etc/rc immediately
after disks are mounted r/w.
I'd like to MFC this before the 4.6 freeze unless there is violent
objection.

1.43 (dfr 04-Apr-97): * [dfr] Kludge until I get around to fixing all the vfs locking.
1.43 (dfr 04-Apr-97): */
The new devfs doesn't support VFS locking. So don't do locking
assertions for devfs vnodes.
With this change, a kernel with options DEBUG_VFS_LOCKS actually
gets to single-user mode.

- When an error occurs processing one file, we must continue to process
the remaining files.
- Convert trailing whitespace to tabs as appropriate.

- malformed environment strings (ones without an '=') were not rejected.
There shouldn't be any of these, but when the static environment is
empty it always begins with one of these; this one should be considered
as the terminator after the end of the environment, but it isn't.
- the comparison of the name being looked up with the name in the
environment was fuzzy -- only the characters up to the length of the
latter were compared, so _getenv_static("foobar") matched "foo=..."
in the environment and everything matched "" in the empty environment.

Garbage pointers in __si_u were not cleared by destroy_dev(). Not
clearing si_disk made the above fatal because the disk layer uses
si_disk as a flag to indicate that the dev_t has been completely
initialized. disk_destroy() clears si_disk for the parent dev_t
but doesn't get called for children.
Not fixed:
- setting the undocumented sysctl debug.free_devt should cause more
complete destruction of the dev_t including clearing of __si_u, but
actually causes the above to panic a little earlier.
- the loop leaks 10 memory allocations per iteration (4 DEVFS, 2 devbuf
and 4 dev_t).
