replacing them with TAILQ's as appropriate. The SCSI code is the
first to be changed -- until the changes are complete, both b_act and
b_actf will be in the buf structure. b_actf will eventually be removed.
1) Make cluster buffer list be a non-malloced chain. This eliminates
yet another 'evil' M_WAITOK and generally cleans up the code.
2) Fix write clustering for ext2fs. It was just broken. Also, ffs
clustering had an efficiency problem that more bawrites were happening
than should have been.
3) Make changes to buf.h to support the above, plus remove b_pfcent
at the request of David Greenman.
Note that the reallocblocks code is disabled pending rewrite for
the cluster buffer list changes.

- don't allow invalid timevals.
- normalize timevals as they are built - don't call timevaladd() with
a possibly invalid timeval and normalize the result.
Fixed a warning.
almost every time someone uses an address. This file is probably not
the right place to keep track of the unused addresses (or used
addresses :->).
Fixed comments on #endif's to match code.
Added defines for ASC and GSC sizes. This file is not the right place
to keep track of scanner addresses, but while there here and we
pretend to keep track of unused addresses, the sizes need to be here
too.
Sorted IO_*SIZE defines.
floppies must have been random in 2.x since we reintroduced sorting
on b_pblkno on 1995/03/18. Drivers still initialize b_cylin/b_resid
although this is no longer used.
Removed unused, wrong function fdsize(). (Returning 0 means that the
device exists and has size 0, not that the device doesn't exist.
swaponvp() allows for size 0 by stupidly calling the d_psize function
twice if the size isn't 0. setdumpdev() doesn't allow for it.)
Continued removing /* ARGSUSED */ from drivers.
introduced.
Fixed the device-driverness of atapi.c and spkr.c.
These changes are actually no-ops because ${DRIVER_C} is the same as
${NORMAL_C} for the i386. I could do without magic CFLAGS. Special
handling should be in the sources if possible.
boot to display "Booting the kernelel...done" instead of "Booting
the kernel".
Removed save and restore of BIOS memory. kzipped kernels haven't
ever overlaid the BIOS memory.
