o Set st_shndx for sym_zero to SHN_UNDEF instead of SHN_ABS.
This gives us something to reliably test against.
o For weak references to undefined sysmbols (as indicated by
having st_shndx equals SHN_UNDEF) in the context of OPDs,
the address of the OPD is to be zero, not the address of
the function it contains.
o For weak references to undefined symbols in all other cases
(only DIR64LSB at this time), the actual relocated value is
to be zero, not the value prior to relocating.
Roughly speaking, weak references to undefined symbols are no-ops.
Tested on: i386, ia64
uuencode(1), and set a umask, so that the mode in the header is predictable.
If it varies, then the test is right to fail.
Remove the note about this test falsely failing, with that in mind.
relocation identifies the symbol to which we need to bind. This
solves a problem seen on ia64 where the symbol hash table does not
contain local symbols and thus resulted in unresolved symbols.
Tested on: alpha, i386, ia64
ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper
to your high-end RAID controller. The interface to the arrays is still
via the block interface; this merely provides a way to circumvent the
RAID functionality and access the SCSI buses directly. Note that for
somewhat obvious reasons, hard drives are not exposed to the da driver
through this interface, though you can still talk to them via the pass
driver. Be the first on your block to low-level format unsuspecting
drives that are part of an array!
To enable this, add the 'aacp' device to your kernel config.

by other bits of code, split struct timecounter into two.
struct timecounter contains just the bits which pertains to the hardware
counter and the reading of it.
struct timehands (as in "the hands on a clock") contains all the ugly bit
fidling stuff. Statically compile ten timehands.
This commit is the functional part. A later cosmetic patch will rename
various variables and fieldnames.

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.

The new devfs doesn't support VFS locking. So don't do locking

With this change, a kernel with options DEBUG_VFS_LOCKS actually
