Use consistant whitespace/comments for #define'ing LABELSECTOR,
LABELOFFSET and MAXPARTITIONS. Easier on the eye when scanning
through all these files. No functional change.

b_cylinder does not need to be set on the callpath down into drivers.
cpu_disklabel can go away, since nothing anymore needs to use it; ok miod

Eliminate a few straggling 'labelsector' field declarations from
cpu_disklabel's. 'labelsector' is not used anywhere according to grep.

significantly simplified disklabel infrastructure. MBR handling becomes MI
to support hotplug media on most architectures. disklabel setup and
verification done using new helper functions. Disklabels must *always*
have a correct checksum now. Same code paths are used to learn on-disk
location disklabels, to avoid new errors sneaking in. Tested on almost all
cases, testing help from todd, kettenis, krw, otto, dlg, robert, gwk, drahn

No need for two *LABELSECTOR and *LABELOFFSET defines that mean the
same thing. Keep LABELSECTOR and LABELOFFSET and nuke
ALPHA_LABELSECTOR and ALPHA_LABELOFFSET.

Kernel still compiles and boots.

Superfluidity pointed out by deraadt@.

Try again with local variable to avoid alignment issues.

"The dosparts member of cpu_disklabel was not used for any persistant
data. Eliminate it, and just use the data being read in while
processing MBR and EBR records.

Should be no functional change.

back out disksubr changes ... since they violate strict alignment on
some architectures (kaboom); that will be fixed in the next iteration
hopefully!

Zap bad144 bad sector info in disklabels. Sparsely used if at all for
a few obsolete and easily replaced disk models. And didn't work anyway
according to Bob, who has tried.

ok beck@

Remove DLT_* logic from Alpha as well, being careful to keep the
checksumming of the native disklabel.

No functional change.

Zap Amiga bits of disklabel.h now that Amiga bits of readdisklabel() are
gone.

'go ahead' deraadt@

Amiga is no longer amoung us. Some architectures were too sentimental
to cut all ties when it left for the attic. Eliminate (theoretical)
ability to read Amiga disklabels on those architectures.

DOSPTYP_EXTENDL; sigh@kuzirabekon.econ.nagasaki-u.ac.jp

Add DOSMBR_SIGNATURE_OFF define, needed for last disklabel change

rename some DOS MBR partition types

add netbsd partition, rename 386BSD one to FreeBSD..

disklabel spoofing for FAT32.

DOSMBR_SIGNATURE, DOSACTIVE; weingart

Use the new bounds_check_with_label API. Add generic support for reading
both little and big endian BSD disklabels. Add a specific hook to read such
a big-endian disklabel as it is found on amiga (normally, however, amiga
uses the native RDB format, which still is not supported).

Add MBR & i386/disklabel probing in a generic fashion usable for more
disklabel types, and for other architectures if they chose. Both read/write
supported for both alpha and i386/arc disklabels. ISO9660 spoofing kept
and tested. Add "option DISKLABEL_ALL" to your config to use.

16 partitions

Merge to NetBSD 961020. Retained our kernel APIs where NetBSD has changed.
-Wall -Wstrict-prototypes -Wmissing-prototypes too.

Add OpenBSD tags. Adapt to OpenBSD *_intr_establish calling convention
