2d333700d6 Fix a witness warning when expanding a hash table. We were allocating the new
hash while holding the lock on a zone.  Fix this by doing the allocation
seperately from the actual hash expansion.

The lock is dropped before the allocation and reacquired before the expansion.
The expansion code checks to see if we lost the race and frees the new hash
if we do.  We really never will lose this race because the hash expansion is
single threaded via the timeout mechanism.

3b69e0094c Remove the hard-coded limit of 3 bytes for EUC encodings.
Satoshi NIIMI-san kindly explained that EUC does not limit the byte length to
any arbitrary number.

We now set the limit to the maximum octet length of the codeset and it is
locale-specific.

9c6b97e023 Fix the play / record rate setting so that it actually works.
The extra microphone channel capability is part of the "normal" ac97
capabilities and not an extended ac97 capability. Now recording on
codecs without a seperate mic channel works.

0b2395fb4a Back out rev 1.17, it breaks dependencies.
With rev 1.7 one cannot build src/bin/sh -- because make fails to create
the buildtools before trying to use them.  Actually it does compile the
buildtools into .o's before trying to use them, but not all the way into
binaries.

5b62962da4 Fix the calculation that determines uz_maxpages. It was off for large zones.
Fortunately we have no large zones with maximums specified yet, so it wasn't
breaking anything.

Implement blocking when a zone exceeds the maximum and M_WAITOK is specified.
Previously this just failed like the old zone allocator did.  The old zone
allocator didn't support WAITOK/NOWAIT though so we should do what we
advertise.

While I was in there I cleaned up some more zalloc logic to further simplify
that code path and reduce redundant code.  This was needed to make the blocking
work properly anyway.

ca0d3fbd5d Clean up the 1/2 a** committing from Thu, 3 May 2001 11:05:39 -0700 (PDT).
Since then we have living with a GPL'ed find(1) due to grabbing getdate.y
from src/contrib/cvs and its user of the GPL'ed xtime.h.  I don't even want
to think about how this could have affected people using our source base.

Would it have been too much trouble to do then what I did now?
Copied getdate.y (public domain) to usr.bin/find and change to use
standard system headers.  find(1) now compiles simply with out having
to go to extra effort to do so.

e93a8a367d - Change killpg1()'s first argument to be a thread instead of a process so
we can use td_ucred.
- In killpg1(), the proc lock is sufficient to check if p_stat is SZOMB
  or not.  We don't need sched_lock.
- Close some races in psignal().  In psignal() there is a big switch
  statement based on p_stat.  All the different cases are assuming that
  the process (or thread) isn't going to change state out from under it.
  To ensure this is true, just lock sched_lock for the entire switch.  We
  practically held it the entire time already anyways.  This also
  simplifies the locking somewhat and actually results in fewer lock
  operations.
- Allow signotify() to be called with the sched_lock held since psignal()
  now does that.
- Use td_ucred in a couple of places.

300593a2cc - Change donice() to take a thread as the first argument instead of a
process so it can use td_ucred.
- Require the target process of donice() to be locked when donice() is
  called.
- Use td_ucred.
- Lock the target process of p_cansee() and while reading the credentials
  of a process.
- Change the logic of rtprio() slightly so it does it's copyin() if needed
  prior to locking the target process.
- rtprio() no longer needs Giant.  In theory with full KSE it would still
  need Giant to protect p_ucred of curproc for the p_canfoo() functions
  but p_canfoo() will be changing to using td_ucred of curthread before
  full KSE hits the tree.

e9c672efdc - Change procfs_control()'s first argument to be a thread pointer instead
of a process pointer.
- Move the p_candebug() at the start of procfs_control() a bit to make
  locking feasible.  We still perform the access check before doing
  anything, we just now perform it after acquiring locks.
- Don't lock the sched_lock for TRACE_WAIT_P() and when checking to see if
  p_stat is SSTOP.  We lock the process while setting p_stat to SSTOP
  so locking the process is sufficient to do a read to see if p_stat is
  SSTOP or not.

95ee443e6c - Change the algorithms of the syscalls to modify process credentials to
allocate a blank cred first, lock the process, perform checks on the
  old process credential, copy the old process credential into the new
  blank credential, modify the new credential, update the process
  credential pointer, unlock the process, and cleanup rather than trying
  to allocate a new credential after performing the checks on the old
  credential.
- Cleanup _setugid() a little bit.

  td_ucred.

f8dd9c1116 If the receiver runs out of space for an received frame in the internal
FIFO or the in-RAM descriptors it will switch to RX_IDLE from where it
is not restarted.

We used to deal with RX_IDLE by doing a total reinit but this lost
our link and caused a potential 30sec autonegotiation against
switches.  This was changed to a less heavyhanded approach, but this
failed to restart the receiver it it were in the RX_IDLE state.

This change adds the RX_IDLE and the RX_FIFO_OFLOW conditions as
triggers for interrupts and receive side processing, and restarts
the receiver when it is RX_IDLE.

Remove the #ifdef notyet'ed nge_rxeoc() function.

49304db558 Revision 1.17 seems to break a subsequent buildworld (i.e. with the new
make installed) in gnu/usr.bin/groff/src/preproc/eqn (which, being a
build tool itself, is built with the original make during buildworld).

The problem seems to be that in str_concat(), the string is not
terminated when the length of the second string is 0.
This apparently can happen during null suffix rule processing.

d375e1c241 Add support for an additional field to the packages/INDEX file. If
present, this field specifies the media volume that the disc is
contained on.  If the volume of a given packages is different than the
current volume of mediaDevice, then the user is prompted --

  "This is disc #%d.  Package %s is on disc #%d\n"
  "Would you like to switch discs now?\n"

If the user selects yes, then DEVICE_SHUTDOWN is called and the user
is then prompted --

  "Please remove disc #%d from you drive, and add disc #%d"

This works well for a carefully crafted INDEX file, but more work
needs to be done to sort dependencies on a given package based on the
volume that they reside on, to minimize the amount of disc flipping
required of the user.

This commit is a no-op for normal INDEX files and FreeBSD CDs.  These
additional features are only used if the INDEX and cdrom.inf file have
multi-volume support.
