7cc0ed53c2 - Move p_cpulimit to struct proc from struct plimit and protect it with
sched_lock.  This means that we no longer access p_limit in mi_switch()
  and the p_limit pointer can be protected by the proc lock.
- Remove PRS_ZOMBIE check from CPU limit test in mi_switch().  PRS_ZOMBIE
  processes don't call mi_switch(), and even if they did there is no longer
  the danger of p_limit being NULL (which is what the original zombie check
  was added for).
- When we bump the current processes soft CPU limit in ast(), just bump the
  private p_cpulimit instead of the shared rlimit.  This fixes an XXX for
  some value of fix.  There is still a (probably benign) bug in that this
  code doesn't check that the new soft limit exceeds the hard limit.

984ea4a3cd Remove 'at' hints for npx and apm as both drivers have identify routines
that add an instance of themselves.  The npx(4) driver doesn't even check
the npx 'port' hint but hardcodes IO_NPX instead.  The npx(4) driver also
will use isa IRQ 13 (on x86, 8 on pc98) by default if no 'irq' hint is
specified, so we don't need that hint either.

e13d3e9276 When creating a snapshot, create a list of initially allocated blocks.
Whenever doing a copy-on-write check, first look in the list of
initially allocated blocks to see if it is there. If so, no further
check is needed. If not, fall through and do the full check. This
change eliminates one of two known deadlocks caused by snapshots.
Handling the second deadlock will be the subject of another check-in.
This change also reduces the cost of the copy-on-write check by
speeding up the verification of frequently checked blocks.

d01b53c175 The appropriate units for disk block addresses are always DEV_BSIZE,
even when the underlying device has a larger sector size. Therefore,
the filesystem code should not (and with this patch does not) try to
use the underlying sector size when doing disk block address calculations.

This patch fixes problems in -current when using the swap-based
memory-disk device (mdconfig -a -t swap ...). This bugfix is not
relevant to -stable as -stable does not have the memory-disk device.

6b6ba96b60 Round out the facilty for a 'bound' thread to loan out its KSE
in specific situations. The owner thread must be blocked, and the
borrower can not proceed back to user space with the borrowed KSE.
The borrower will return the KSE on the next context switch where
teh owner wants it back. This removes a lot of possible
race conditions and deadlocks. It is consceivable that the
borrower should inherit the priority of the owner too.
that's another discussion and would be simple to do.

Also, as part of this, the "preallocatd spare thread" is attached to the
thread doing a syscall rather than the KSE. This removes the need to lock
the scheduler when we want to access it, as it's now "at hand".

DDB now shows a lot mor info for threaded proceses though it may need
some optimisation to squeeze it all back into 80 chars again.
(possible JKH project)

Upcalls are now "bound" threads, but "KSE Lending" now means that
other completing syscalls can be completed using that KSE before the upcall
finally makes it back to the UTS. (getting threads OUT OF THE KERNEL is
one of the highest priorities in the KSE system.) The upcall when it happens
will present all the completed syscalls to the KSE for selection.

bc46f827dc Fix for the panic when using a Promise TX2.
The problem is that the code does a check for the granparent of
the Promise chip, if this is a bridge of the right type, we have
a TX4 on our hands, and need to handle that ones "issues".
Now the grandparent check cause subtle bugs in the newbus system,
mainly that pci_get_devid doesn't return an error value.
This patch works around the issue by using BUS_READ_IVAR() instead.

13b9c6f277 Fix the location of the length bytes in the 12-byte read/write CDB
structure.  This has been broken since 1998, but probably hasn't been
noticed because it takes a read/write of 64K blocks (32MB with 512 byte
blocks) to trigger using the 12 byte read/write CDB in scsi_read_write().

8eaa35ca87 It seems that the only problem with UFS2 booting on i386 is the 64bit
divide/remainder calls.  For reasons not resolved, compiling the
relevant routines from libkern into boot2 results in stack corruption.

Do the simple thing: Don't use 64bit divide/remainder operations.

o Better resume code.  Move the comments around.  Force the socket state to

o Intercept the interrupt requests and keep a list of interrupts to service
  ourselves.  When the card attaches, set its OK bit.  When we get a card
  status change interrupt for that card, clear the OK bit.  Don't call the
  ISR if the OK bit is cleared.  Iwasaki-san and yamamoto-san have both
  sent me patches that fix the same problem this fixes, but at the pccard
  level.

f7540bad93 o Add routines to return the location and pnpinfo for this card.
Note, we return the PCI pnp info, but in fact that's wrong to do
  since that data is not defined for CardBus cards.  CardBus says that
  these registers are undefined and one should use the CIS to do
  device matching.  To date, all CardBus cards have had these
  registered defined, no doubt because they are using common silicon
  to produce both the PCI cards and the CardBus cards.  However, it isn't
  any worse than the rest of the system, so just note it in passing and
  move on.
