16c1138c89 Change BUS_SPACE_UNRESTRICTED (~0ul) to plain ~0 when used in the
'int nsegments' argument to bus_dma_tag_create().  ~0ul does not fit in
an int on machines with 64 bit longs.

- Suppress additional whitespace after the subsection header (.Ss).
  (This affects a tiny number of our manpages.)

- Allow for a layout customization of the OS name in the document
  title (.Dt).  (Needed for Russian and French manpages.)

98d275df37 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.

b6cef5648d 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.

4526ed6ffb Convert make(1) to use ANSI style function declarations. Variable
documentation already adequatedly existed in the description in most
cases.  Where it did not, it was added.  If no documentation existed
beforehand, then none was added.  Some unused dummies for use in the
traversal functions were marked as __unused during the conversion.
Occasionally, local style fixes were applied to lines already being
modified or influenced.

Now make(1) should always build with WARNS=3.

48bfcddd94 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.

3685096edb Remove the wargames(6) novelty [and not the fun kind]:
1) It never was very funny.
	2) It was a N line shell script where N is less than
	   X, where X is the number of lines of the Berkeley
	   copyright and license.
	3) I rewrote it in C with the intention of making it
	   more interactive, ala the movie, but never did.
	4) Because it really is possible for at least some
	   parts of a distribution to shrink between releases.

c13beb0171 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.

ead5f16cef 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().

7cf5744b6b 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.

c121fd80b8 Do not strip CTL* escapes from redirection filenames in argstr(); they
are later stripped with rmescapes() in expandarg(). If the filename has
already been unescaped, doing it again in rmescapes() can walk off the
end of the string, leading to memory corruption and eventually SIGSEGV.
