- Make sure we don't release the READ CAPACITY CCB twice
- If we have a device that needs a 16 byte READ CAPACITY command, make
sure we call xpt_schedule() so we can get a CCB.
- Don't unlock the peripheral until we're fully probed.
Many thanks to Julian Elischer for providing hardware and testing this.

(If there is a legitimate need to correctly encode and pack a
disklabel with an invalid checksum custom tools can be built for
that.)
Make bsd_disklabel_le_dec() validate the magics, number of partitions
(against a new parameter) and the checksum.
Vastly simplify the logic of the GEOM::BSD class implementation:
Let g_bsd_modify() always take a byte-stream label.
This simplifies all users, except the ioctl's which now have to
convert to a byte-stream first. Their loss.
g_bsd_modify() is called with topology held now, and it returns
with it held.
Always update the md5sum in g_bsd_modify(), otherwise the check
is no use after the first modification of the label. Make the
MD5 over the bytestream version of the label.
Move the rawoffset hack to g_bsd_modify() and remove all the
inram/ondisk conversions.
Don't configure hotspots in g_bsd_modify(), do it in taste instead,
we do not support moving the label to a different location on the
fly anyway.
This passes all current regression tests.
- Use htole* macros where appropriate so that the driver could work on non-x86 architectures
- Use m_getcl() instead of MGETHDR/MCLGET macros

Note: this might print failure messages on some systems, unfortunatly
the info from the device, stating if flushing is supported, cannot be trusted
so the operation is always issued on all devices, just in case...
just return it. Don't try to reinitialize it. This should fix a
number of inconsistencies that some people encountered with "vinum
start".

All functionality from the previous system has been preserved, and
users should still customize their system boot with the familiar
methods, rc.conf, rc.conf.local, rc.firewall, sysctl.conf, etc.
Users who have customized versions of scripts that have been removed
should take great care when upgrading, since the compatibility code
that used those old scripts has also been removed.
double free of a mbuf occurs and cause an immediate panic, rather
than allowing free list corruption to occur.
This code is trapped under INVARIANTS, so it should not cause any
change in default performance.

of <machine/pc/bios.h> specific to i386 and added a conditional define
for BIOS_PADDRTOVADDR that depends on ISA_HOLE_START. The latter is
undefined on alpha and ia64. Since the former is defined the same on
both alpha and ia64, assume the ISA_HOLE_START dependent definition
is specific to amd64 and use the identity-mapping in all other cases.
This of course is getting uglier every day...
quite excessive, and caused the available space to be used up too

- Double the IOTSB size 64kB, for a DVMA area size of 64MB.
This should fix DMA problems on e450s and other large machines due
to DVMA space exhaustion, which were introduced in my last IOMMU
code revision in January.
