I have some code (in sginfo) that requests the first 4 bytes
of SCSI INQUIRY VPD pages to get their length then asks for
that exact length in a follow up request to fetch the payload.
Just like I saw with 36 byte standard INQUIRYs (no fixed)
I get a buffer  full or zeroes.

BTW SCSI standards dictate that in situations where the allocation
length (in the cdb) is less than what is needed that what can be
sent shall be sent (i.e. truncated and without any error indication
or modification to the part of the response returned).
In other words it is up the the application client to take remedial
action.

Changelog:
   - fix off-by-1 allocation length issue with SCSI
     INQUIRY VPD pages 0x80 and 0x83

libata made the assumption that (for PIO commands in this case)
it could modify DMA memory at the kernel-virtual address, after
mapping this.  This is incorrect, and fails on e.g. platforms that
copy DMA memory back and forth (swiotlb on Intel EM64T and IA64).

Remove this assumption by ensuring that we only call the DMA mapping
routines if we really are going to use DMA for data xfer.

Also:  remove a bogus WARN_ON() in ata_sg_init_one() which caused
bug reports (but no problems).

They turn out to be buggy, and result in the same filename being
reported twice when htree directory indexing is enabled.

Thanks for Kris Karas for helping chase it down. Also reported
by Holger Kiehl.

Start of a big DVB update.


The reasons for revamping the DVB frontend architecture:

Just as analog TV cards, DVB cards need some sort of tuner to tune to the
desired frequency of the digital transponder.  Tuning alone doesn't give you a
digital DVB datastream, however, you need a demodulator as well.  The
combination of tuner and demodulator is called frontend in the DVB world.
Tuner and demodulator are both accessed via the serial i2c bus on all DVB
cards out there.  So, technically a frontend consists of two i2c helper
chipsets.

In former times when there was only a handful of different DVB cards, the
frontend was encapsulated in one tin box.  Some people had the idea that there
should be one "frontend driver" instead of dedicated tuner and demodulator
drivers.  A bad idea.

As time went on, different manufacturers used the same tuner and demodulator
combination, but used a different wiring for the tuner or did other technical
changes.  The only possibility to support different cards with one combined
frontend driver was to add hardware dependent tuner code inside the generic
i2c frontend drivers.  Yuck.

So there was a need for communication between the i2c frontend driver and the
hardware depenedent driver, for example to exchange initialization code for
the tuner.  Unfortunately, the i2c infrastructure is one way, from the i2c
client to the i2c adapter using a non-typesafe ioctl() like interface, which
is ugly by itself.  Greg K-H and others refused the idea to add an iotctl()
like interface from the i2c adapter to the i2c client and instead proposed to
use a typesafe interface instead.  We all agreed with that.

The existing i2c infrastructure heavily depends on the probing facility, ie.
clients probe for their existence on i2c busses.  This is dumb for most i2c
busses out there that sit on dedicated hardware.  A DVB card is uniquely
identified with pci or usb subvendor and subsystem ids, so on that particular
bus we exactly *know* which kinds of i2c helper chipsets sit on there.

Up to now this wasn't a problem, because we could fix all conflicts manually
until half a year ago.  By that date, we found two different DVB designs which
used different demodulators that unfortunately use the same i2c address and
which cannot be distinguished by hardware tricks (ie.  different number of
registers, some fixed hw dependent register,...)

Getting a usable DVB card depended on the load order of the modules, because
the i2c core probed the demodulator drivers one after another and the first
one won the race.  Compiling all drivers statically into the kernel resulted
in non-working cards.

Our solution is as follows: we agreed to keep the basic underlying kernel i2c
infrastructure, but we decided not to register our bussed and chipsets to the
kernel i2c "probing" infrastructure.  Instead, we killed the tuner parts of
the frontend drivers and put them into the dedicated hardware drivers (this is
were they technically belong, they are highly hardware dependent) and we
changed the frontend drivers to pure demodulator drivers (which are hardware
independend).  There is now a type-safe functional dependency between the
drivers and the demodulator drivers, the drivers explicitely ask the
demodulator drivers to attach to their i2c bus.  The only negative aspect of
that approach is that for some hardware there are now more dependencies to
demodulator drivers than needed, ie.  a small amount of memory is wasted.

In 2.6.8 the code for the BLKRRPART ioctl was changed
to return EIO when no partitions were found, such as
on an empty disk. This breaks some partitioning programs
and is also confusing: "Input/Output error" while in fact
nothing was wrong with this brand new all blank disk.

This restores old behaviour.

We recently found a problem that was causing memory corruption during
boot on IBM POWER5 machines.  The problem was that the if you have a
USB keyboard and it is set to the input device for the firmware, it
will still be active when the kernel is started.  That means that the
OHCI controller has pointers to various memory areas that it polls for
transfers to do.  When we start using that same memory in the kernel,
bad things can happen.  (This isn't a problem on powermacs because the
Apple OF implements a "quiesce" call which turns off all the devices
it is using.)

This patch fixes the problem by calling the Open Firmware "close"
method for the input device.  Stephen Rothwell and I have verified
that doing this fixes the problem on the POWER5 machine where we
observed it.  I verified that this patch doesn't cause any problems on
powermacs.

I think this patch should go into 2.6.10 since it fixes a nasty memory
corruption bug that can cause rather subtle and hard-to-diagnose
problems during boot.  (The symptom on the POWER5 machine with the
particular kernel that we were using was that reading /proc/net/tcp
would oops, due to one of the pointers in tcp_ehash being corrupted.)
