2813692cc2 Merge common XPT_CALC_GEOMETRY functions into a single convenience function.
Devices below may experience a change in geometry.

* Due to a bug, aic(4) never used extended geometry.  Changes all drives
  >1G to now use extended translation.
* sbp(4) drives exactly 1 GB in size now no longer use extended geometry.
* umass(4) drives exactly 1 GB in size now no longer use extended geometry.

For all other controllers in this commit, this should be a no-op.

891619a66d Use bioq_flush() to drain a bio queue with a specific error code.
Retain the mistake of not updating the devstat API for now.

Spell bioq_disksort() consistently with the remaining bioq_*().

#include <geom/geom_disk.h> where this is more appropriate.

60794e0478 Centralize the devstat handling for all GEOM disk device drivers
in geom_disk.c.

As a side effect this makes a lot of #include <sys/devicestat.h>
lines not needed and some biofinish() calls can be reduced to
biodone() again.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

7874f606d5 Introduce a new taskqueue that runs completely free of Giant, and in
turns runs its tasks free of Giant too.  It is intended that as drivers
become locked down, they will move out of the old, Giant-bound taskqueue
and into this new one.  The old taskqueue has been renamed to
taskqueue_swi_giant, and the new one keeps the name taskqueue_swi.

(3) Problem: PANIC from loading driver when

Fix - put #idef freebsd version < 500000 for
bmaj -1 -> amrd_cdevsw

with DAMR_DEBUG param enabled in Makefile
Fix - fix the warnings so driver can compile

7812d86f03 (This commit touches about 15 disk device drivers in a very consistent
and predictable way, and I apologize if I have gotten it wrong anywhere,
getting prior review on a patch like this is not feasible, considering
the number of people involved and hardware availability etc.)

If struct disklabel is the messenger: kill the messenger.

Inside struct disk we had a struct disklabel which disk drivers used to
communicate certain metrics to the disklayer above (GEOM or the disk
mini-layer).  This commit changes this communication to use four
explicit fields instead.

Amongst the benefits is that the fields do not get overwritten by
wrong or bogus on-disk disklabels.

Once that is clear, <sys/disk.h> which is included in the drivers
no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in,
the few places that needs them, have gotten explicit #includes for
them.

The disklabel inside struct disk is now only for internal use in
the disk mini-layer, so instead of embedding it, we malloc it as
we need it.

This concludes (modulus any mistakes) the series of disklabel related
commits.

I belive it all amounts to a NOP for all the rest of you :-)

f90c382c0c Make FreeBSD "struct disklabel" agnostic, step 311 of 723:
Rename diskerr() to disk_err() for naming consistency.

Drop the by now entirely useless struct disklabel argument.

Add a flag argument for new-line termination.

Fix a couple of printf-format-casts to %j instead of %l.

Correctly print the name of all bio commands.

Move the function from subr_disklabel.c to subr_disk.c,
and from <sys/disklabel.h> to <sys/disk.h>.

Use the new disk_err() throughout, #include <sys/disk.h> as needed.

Bump __FreeBSD_version for the sake of the aac disk drivers #ifdefs.

Remove unused disklabel members of softc for aac, amr and mlx, which seem
to originally have been intended for diskerr() use, but which only rotted
and got Copy&Pasted at least two times to many.

b40cbf61a7 In case the driver runs on an HP NetRaid controller, attempt to properly
decode the BIOS and firmware version and announce the board as HP NetRaid.

This has been tested with a NetRaid 3si controller, the BIOS/firmware
printout should also work for other NetRaid controllers but the type
detection for other NetRaids (such as the 1si) will not work due to the
lack of hardware.

9f1776230d Major update to the AMI MegaRAID driver.
- New support for 40LD firmware found in Series 475 and 471 adapters.
 - Better support for 8LD firmware adapters
 - Ioctl passthrough interface for userland utilities.
 - Improved error handling and queueing.
 - Several bugfixes (including the 'still open' shutdown bug and
   closing some small race conditions).
 - Zone-style command allocator, reducing memory wasted under heavy
   load conditions.
 - CAM interface (disabled and not fully working) for SCSI passthrough
   access to non-disk devices

help in making this happen.
