driver to work properly and reliably with more than 4GB of RAM. Of the
three data paths that exist in the driver, (block, CAM, ioctl), the ioctl
path has not been well tested with these changes due to difficulty with
finding an application that uses it that actually works.

Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.
Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.
Retain the mistake of not updating the devstat API for now.
Spell bioq_disksort() consistently with the remaining bioq_*().

As a side effect this makes a lot of #include <sys/devicestat.h>

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,

Fix - polling was implemented incorrectly for
adapter enquiry and adapter flush.
(2) Problem: PANIC when unloading driver
as module.
Fix - device nodes are not destroyed for amr0,
and amrd* when driver is unloaded
(3) Problem: PANIC from loading driver when
3ware adapter present, error message "Warning

Fix - put #idef freebsd version < 500000 for
bmaj -1 -> amrd_cdevsw
(4) Problem: warnings in driver when compiling
with DAMR_DEBUG param enabled in Makefile
Fix - fix the warnings so driver can compile
when -Werror is present in Makefile.

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.

Fix amr_map_command so that 40LD-specific commands get the scatter-gather
list count in the right place. I don't understand why AMI did it like
this, but now the AMI MegaManager can talk to the newer (1600 and later)
controllers.
Remove an unused variable.
Include <machine/clock.h> when necessary.
Tweak some debugging levels to make things more intelligible.
- 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
Thanks to AMI for supplying a pile of new adapters and various other
help in making this happen.

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall

Diskdrivers and similar stuff below specfs::strategy() should no

Still a few bogus uses of struct buf to track down.

- Remove a number of redundant efforts to poll the card for completed
commands. This is what interrupt handlers are for.
- Limit the maximum number of outstanding I/O transactions. It seems
that some controllers report more than they can really handle,

- Don't use 'wait' mode for anything where the controller might not
be able to generate interrupts. (Keep the 'wait' mode though sa it
will become useful when we start taking userspace commands.

field in struct buf: b_iocmd. The b_iocmd is enforced to have
exactly one bit set.
B_WRITE was bogusly defined as zero giving rise to obvious coding
mistakes.
Also eliminate the redundant struct buf flag B_CALL, it can just
as efficiently be done by comparing b_iodone to NULL.
Should you get a panic or drop into the debugger, complaining about
"b_iocmd", don't continue. It is likely to write on your disk
where it should have been reading.
This change is a step in the direction towards a stackable BIO capability.

This loop needs something to tie it to real time, rather than just the CPU's
