The PCI ID table in the DAC960 driver conflicts with some devices
that use the ipr driver. All ipr adapters that use this chip
have an IBM subvendor ID and all DAC960 adapters that use this
chip have a Mylex subvendor id.

This is a particularly ugly on-failure bug, possibly security, since the
lack of error handling here is covering up another class of bug: failure to
handle copy_to_user() return values.
The I4L API function ->readstat() returns an integer, and by looking at
several existing driver implementations, it is clear that a negative return
value was meant to indicate an error.
Given that several drivers already return a negative value indicating an
errno-style error, the current code would blindly accept that [negative]
value as a valid amount of bytes read. Obvious damage ensues.
Correcting ->readstat() handling to properly notice errors fixes the
existing code to work correctly on error, and enables future patches to
more easily indicate errors during operation.

The 8110SB based n2100 board signals a lot of what ought to be
PCI data parity errors durint operation of the 8169 as target.
Experiment proved that the driver can ignore the error and
process the packet as if nothing had happened.
Let's add an ad-hoc knob to enable users to fix their system while
avoiding the risks of a wholesale change.

ATAPI devices transfer fixed number of bytes for CDBs (12 or 16). Some
ATAPI devices choke when shorter CDB is used and the left bytes contain
garbage. Block SG_IO cleared left bytes but SCSI SG_IO didn't. This patch
makes SCSI SG_IO clear it and simplify CDB clearing in block SG_IO.

Not all graphic page remappers support physical addresses over the 4GB
mark for remapping, so while some do (the AMD64 GART always did, and I
just fixed the i965 to do so properly), we're safest off just forcing
GFP_DMA32 allocations to make sure graphics pages get allocated in the
low 32-bit address space by default.
AGP sub-drivers that really care, and can do better, could just choose
to implement their own allocator (or we could add another "64-bit safe"
default allocator for their use), but quite frankly, you're not likely
to care in practice.
So for now, this trivial change means that we won't be allocating pages
that we can't map correctly by mistake on x86-64.
[ On traditional 32-bit x86, this could never happen, because GFP_KERNEL
would never allocate any highmem memory anyway ]

An md array can be asked to change the amount of each device that it is using,
and in particular can be asked to use the maximum available space. This
currently only works if the first device is not larger than the rest. As
'size' gets changed and so 'fit' becomes wrong. So check if a 'fit' is
required early and don't corrupt it.

When suspending a device-mapper device, dm_suspend() sleeps until all
necessary I/O is completed. This state is triggered by a callback from
persistent_commit(). But some I/O can still be issued *after* the callback
(to prepare the next metadata area for use if the current one is full). This
patch delays the callback until after that I/O is complete.

On an nForce4-equipped machine with two SATA disk in raid1 setup using dmraid,
we experienced frequent deadlock of the system under high i/o load. 'cat
/dev/zero > ~/zero' was the most reliable way to reproduce them: Randomly
after a few GB, 'cp' would be left in 'D' state along with kjournald and
kmirrord. The functions cp and kjournald were blocked in did vary, but
kmirrord's wchan always pointed to 'mempool_alloc()'. We've seen this pattern
on 2.6.15 and 2.6.17 kernels. http://lkml.org/lkml/2005/4/20/142 indicates
that this problem has been around even before.
So much for the facts, here's my interpretation: mempool_alloc() first tries
to atomically allocate the requested memory, or falls back to hand out
preallocated chunks from the mempool. If both fail, it puts the calling
process (kmirrord in this case) on a private waitqueue until somebody refills
the pool. Where the only 'somebody' is kmirrord itself, so we have a
deadlock.
I worked around this problem by falling back to a (blocking) kmalloc when
before kmirrord would have ended up on the waitqueue. This defeats part of
the benefits of using the mempool, but at least keeps the system running. And
it could be done with a two-line change. Note that mempool_alloc() clears the
GFP_NOIO flag internally, and only uses it to decide whether to wait or return
an error if immediate allocation fails, so the attached patch doesn't change
behaviour in the non-deadlocking case. Path is against current git
(2.6.18-rc4), but should apply to earlier versions as well. I've tested on
2.6.15, where this patch makes the difference between random lockup and a
stable system.

The device-mapper core does not perform any remapping of bios before passing
them to the targets. If a particular mapping begins part-way into a device,
targets obtain the sector relative to the start of the mapping by subtracting
ti->begin.
The dm-raid1 target didn't do this everywhere: this patch fixes it, taking
care to subtract ti->begin exactly once for each bio.

The reference counting on dm-mod is zero if no mapped devices are open. This
is incorrect, and can lead to an oops if the module is unloaded while mapped
devices exist.
This patch claims a reference to the module whenever a device is created, and
drops it again when the device is freed.
Devices must be removed before dm-mod is unloaded.

Persistent snapshots currently store a private copy of the chunk size.
Userspace also supplies the chunk size when loading a snapshot. Ensure
consistency by only storing the chunk_size in one place instead of two.
Currently the two sizes will differ if the chunk size supplied by userspace
does not match the chunk size an existing snapshot actually uses. Amongst
other problems, this causes an incorrect 'percentage full' to be reported.
The patch ensures consistency by only storing the chunk_size in one place,
removing it from struct pstore. Some initialisation is delayed until the
correct chunk_size is known. If read_header() discovers that the wrong chun
size was supplied, the 'area' buffer (which the header already got read into
is reinitialised to the correct size.

In some cases when using VSB, the AGC status register has been known to
falsely report "no signal" when in fact there is a carrier lock. The
datasheet labels these status flags as QAM only, yet the lgdt330x

This patch allows for the carrier recovery lock status register to be
tested, even if the agc signal status register falsely reports no signal.

This is confirmed to fix a hang due to PCI resource conflicts with
setting up the Cardbus bridge on old laptops with the 440MX chipsets.
Original report by Alessio Sangalli, lspci debugging help by Pekka
Enberg, and trial patch suggested by Daniel Ritz:
"From the docs available i would _guess_ this thing is really similar
to the 82443BX/82371AB combination. at least the SMBus base address
register is hidden at the very same place (32bit at 0x90 in function
3 of the "south" brigde)"
The dang thing is largely undocumented, but the patch was corroborated
by Asit Mallick:
"I am trying to find the register information. 440MX is an integration of
440BX north-bridge without AGP and PIIX4E (82371EB). PIIX4 quirk
should cover the ACPI and SMBus related I/O registers."
and verified to fix the problem by Alessio.

There 1022:7450 is listed as "AMD-8131 PCI-X Bridge" while 1022:7451
is listed as "AMD-8131 PCI-X IOAPIC". Yet, the current definition for
0x7450 is PCI_DEVICE_ID_AMD_8131_APIC. It seems to me like that name
should map to 0x7451, while a name like PCI_DEVICE_ID_AMD_8131_BRIDGE
should map to 0x7450.
