aa6db4230d Used daddr_t's, not ints, to store disk block numbers. Updated printf
formats and args to match.  Fixed old printf format errors (all related;
most were hidden by calling printf indirectly).

This change somehow avoids compiler bugs for 64-bit longs on i386's,
although it increases the number of 64-bit calculations.

14d9217731 Convert tqdisksort to bufqdisksort. Honor the B_ORDERED buffer flag
so that meta-data writes go out to the device in the right order.

7e88aafca7 Use the correct size for a sector in the search for a label in
readdisklabel().  Sectors may be larger than DEV_BSIZE.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

4eb73cdaff Removed all references to b_cylinder (aka b_cylin). It was evil and
hasn't been used for a year or two since disksort() started sorting
on b_pblkno.

7cb29d3394 This update adds the support for != 512 byte sector SCSI devices to
the sd & od drivers. There is also slight changes to fdisk & newfs
in order to comply with different sectorsizes.
Currently sectors of size 512, 1024 & 2048 are supported, the only
restriction beeing in fdisk, which hunts for the sectorsize of
the device.
This is based on patches to od.c and the other system files by
John Gumb & Barry Scott, minor changes and the sd.c patches by
me.
There also exist some patches for the msdos filesys code, but I
havn't been able to test those (yet).

253c0899b2 Don't include <sys/conf.h> for the kernel in disk-related headers.
It is needed for implementation details but very little of it is
needed for the interface.  Include it in the few places that didn't
already include it.

Include <sys/ioccom.h> in <sys/disklabel.h> (as already in
<sys/diskslice.h>) so that all the disk-related headers are almost
self-sufficient.

10d245c58a Yet more b_flags fixes. The previous ones broke the clearing of B_DONE
and B_READ before writing.  This was was fatal.  They also broke the
clearing of B_INVAL before doing i/o.  This didn't actually matter.

f5d1e6dae6 Fix a bug that b_flags was getting unnecessarily modified by
the slice code.  The effect up to now has been insignficant, but
improved buffer allocation code will break with this problem.

dc4a0cee58 Update the wd.c driver to use the new TAILQ scheme for device
buffer queue.  Also, create a new subroutine 'tqdisksort' that
is an improved version of the original disksort that also uses
TAILQs.

4bb0ce8ce3 Fix correct_writedisklabel() and writedisklabel(). Their setting of
bp->b_flags has been broken for many years:
a) they didn't set B_BUSY for doing i/o.  This has been fatal since
   1995/07/25 when biodone() started checking that B_BUSY is set.
b) they didn't set B_INVAL for releasing the buffer.  This at best
   just put a useless buffer in the LRU queue for a little while.

Fix a couple of spelling errors and complete a couple of function
pointer declarations.

74ca9fa64f On closer inspection, it turns out that all of the callers of disksort
are already at splbio()...so back out the last change to disksort.

5d210d3fd4 Since buffers can be pulled off of the disk queue at interrupt time and
disksort is called at non-interrupt time and can be actively traversing
the list when that happens, there is a very small window of vulnerability.
Close it by protecting disksort with splbio().

de13c90ff2 Adjust slice names in diskerr() for the rearranged slice numbers. The
mapping from numbers to names is messy for backwards compatibility.
E.g., for driver "sd", unit "0":

slice 0: omit the slice number for compatibility; names are sd0[a-h].
slice 1: omit the partition letter 'c' because the whole disk device
         shouldn't have anything to do with partitions; sd0 is the
         only name.
slices 2-31: subtract 1 from slice number to compensate for the
         compatibility slice 0; names are sd0s[1-30][a-h].

1be9232f73 This basically allows you to stick a disklabel on any partition.
For it to be useful, you must stick your disklabel on the partition which
starts where the MBR says FreeBSD lives.  If you don't do that, you might
get a bad day.

Oh, that probably also means that putting swap there is a bad idea...
