We have increased PCIBIOS_MIN_IO to 0x4000, but still want
motherboard resources to be allocated properly. So we need
to state 0x1000 (according to the comment) limit explicitely.

The reason we have PCIBIOS_MIN_IO and PCIBIOS_MIN_CARDBUS_IO is because
we want to protect badly documented motherboard PCI resources and thus
don't want to allocate new resources in low IO/MEM space.
However, if we have already discovered a PCI bridge with a specified
resource base, that should override that decision.
This change will allow us to move the "careful" region upwards without
resulting in problems allocating resources in low mappings. This was
brought on by us having allocated a bus resource at 0x1000, conflicting
with a undocumented VAIO Sony PI resources.
CFQ will currently stall when using write barriers and the default
max_depth setting of 1, since we artificially need a depth of 2 when
pre-pending the first flush. So never deny the barrier request going to
the device.
This is a regression since 2.6.12, it was found in SUSE testing.

Recent changes (well, dating from 12 July) have broken cardbus on my
powerbook: I get 3 messages saying "no resource of type xxx available,
trying to continue", and if I plug in my wireless card, it complains
that there are no resources allocated to the card. This all worked in
2.6.12.
Looking at the code in yenta_socket.c, function yenta_allocate_res,
it's obvious what is wrong: if we get to line 639 (i.e. there wasn't a
usable preassigned resource), we will always flow through to line 668,
which is the printk that I was seeing, even if a resource was
successfully allocated. It looks to me as though there should be a
return statement after the two config_writel's in each of the 3
branches of the if statements, so that the function returns after
successfully setting up the resource.
The patch below adds these return statements, and with this patch,
cardbus works on my powerbook once again.

When leaving S3 state, the AGP bridge may not have all PCI configuration
registers set in the same way as they were at boot. This should be fixed
by pci_restore_state - however, the APBASE register cannot be set to
conflict with the APSIZE register. If APSIZE is larger than it was before
suspend, pci_restore_state will not restore APBASE correctly. The attached
patch adds an extra item to the agp_bridge_data structure and uses it to
store the value of APBASE. On resume, this is then written after APSIZE
has been set. This patch only touches the path used for Intel chipsets
without integrated graphics, and may need to be extended to work with the
others.

This stuff actually is a leftover of an early 2.4 PCI setup code
and apparently it stopped working after some "bridge_ctl" changes.
So the best thing we can do is just to remove it and rely on the fact
that any firmware *has* to configure VGA port forwarding for the boot
display device properly.
But then we need to ensure that the bus->bridge_ctl will always
contain valid information collected at the probe time, therefore
the following change in pci_scan_bridge() is needed.

This patch was sent first time very long time ago,
but magically was disapeared, it probably exists
in your queue, but to be sure, I resend it.
If can not be applied cleanly after your w1 queue is flushed
into upstrem tree, just drop it.
Thanks.

The 24RF08 corruption prevention in the eeprom and max6875 drivers wasn't
complete. For one thing, the additional quick write should happen as soon
as possible and unconditionally, while both drivers had error paths before.
For another, when a given chip is forced, the core does not emit a quick
write, so a second quick write would cause the corruption rather than
prevent it.
I plan to move the corruption prevention in the core in the long run, so
that individual drivers don't have to care anymore. But I need to merge
i2c_probe and i2c_detect before I do (work in progress).

DS1339 manual, page 6, chapter Date and time operation:
The DS1339 can be run in either 12-hour or 24-hour mode. Bit 6 of the
hours register is defined as the 12-hour or 24-hour mode-select bit.
When high, the 12-hour mode is selected.
Patch below makes ds1337 driver work as documented in manual.

This patch is an attempt to fix deadlocks discovered in the core dm.
The problems boil down to md->lock having to be held in too many places, so
I've split it into two: md->suspend_lock and md->io_lock.
suspend_lock is now held throughout dm_suspended() as well as dm_resume()
and dm_swap_table() so that these functions cannot run concurrently:
there's no requirement for that and it added complexity.
DMF_FS_LOCKED becomes redundant: DMF_SUSPENDED provides adequate
protection.

Reject code 24 is port and CM redirection, not just port redirection.
Port redirection alone is code 25.
Therefore we should rename code 24 to IB_CM_REJ_PORT_CM_REDIRECT and
use IB_CM_REJ_PORT_REDIRECT for code 25.

This patch adds functionality to check the PCI sub-class code of an
AHCI capable device before disabling AHCI. It fixes a bug where an
ICH7 sata controller is being setup by the BIOS as sub-class 1 (ide)
and the AHCI control registers weren't being initialized, thus causing
an IO error in piix_disable_ahci().

sys_reboot() now calls device_suspend(), so it is no longer necessary for
the e1000 driver to register a reboot notifier [in fact doing so results in
e1000_suspend() getting called twice].
(akpm: we need to fast-track this. It's causing ia64 to oops on shutdown)

This patch adds per disk queue functionality to cciss. Sometime back I
submitted a patch but it looks like only part of what I needed. In the 2.6
kernel if we have more than one logical volume the driver will Oops during
rmmod. It seems all of the queues actually point back to the same queue.
So after deleting the first volume you hit a null pointer on the second
one.
This has been tested in our labs. There is no difference in performance,
it just fixes the Oops.

Debugging and description from: Noah Misch <noah@cs.caltech.edu>
When a driver calls pcmcia_request_irq with IRQ_HANDLE_PRESENT unset, it looks
for an open IRQ by request_irq()ing with a dummy handler and NULL dev_info.
free_irq uses dev_info as a key for identifying the handler to free among
those sharing an IRQ, so request_irq returns -EINVAL if dev_info is NULL and
the IRQ may be shared. That unknown error code is the -EINVAL.
It looks like only pcnet_cs and axnet_cs are affected. Most other drivers let
pcmcia_request_irq install their interrupt handlers. sym53c500_cs requests
its IRQ manually, but it cannot share an IRQ.
The appended patch changes pcmcia_request_irq to pass an arbitrary, unique,
non-NULL dev_info with the dummy handler.
