This code was never designed to handle more than one instance of do_work()

The recent change to never ignore the bitmap, revealed that the bitmap isn't
begin flushed properly when an array is stopped.
We call bitmap_daemon_work three times as there is a three-stage pipeline for
flushing updates to the bitmap file.

thing in all cases...
Firstly, R1BIO_Degraded was being set in a number of places in the resync
code, but is never used there, so get rid of those settings.
Then: When doing a resync, we want to clear the bit in the bitmap iff the
array will be non-degraded when the sync has completed. However the current
code would clear the bitmap if the array was non-degraded when the resync
*started*, which obviously isn't right (it is for 'resync' but not for
'recovery' - i.e. rebuilding a failed drive).
This patch calculated 'still_degraded' and uses the to tell bitmap_start_sync
whether this sync should clear the corresponding bit.

The code currently will ignore the bitmap if the array seem to be in-sync.
This is wrong if the array is degraded, and probably wrong anyway. If the
bitmap says some chunks are not in in-sync, and the superblock says everything
IS in sync, then something is clearly wrong, and it is safer to trust the
bitmap.

Until the bitmap code was added,

no_overlay bttv parameter implemented to fix OOPS on some PCI chipsets
(like some VIA) with these behaviors:
1) If pci_quicks does identify the chip as having troubles to
handle PCI2PCI transfers, no_overlay defaults to 1. The user may force
it to 0, to reenable (not recommended).
2) For newer chipsets not blacklisted, no_overlay=1 is provided as a
workaround until PCI chipset included on /drivers/pci/quirks.c

Several people noticed we dropped quite a bit on benchmark figures.
OK, it was my fault but unfortunately I discovered I ran out of brown
paper bags a while ago and forgot to reorder them.
The issue is that a construct introduced in the conversion of the
driver to use the transport class keyed off whether the block request
was tagged or not. However, the aic7xxx driver doesn't properly set
up the block layer TCQ (it uses the wrong API), so the driver now
things all requests are untagged and we keep it to a queue depth of a
single element. Oops.
The fix is to use the correct TCQ API.

Patch from Ian Campbell
On PXA255 there is no way to disable the watchdog. Turning off OIER[E3]
as suggested in the existing comment does not work.
I posted a note to the ARM mailing list a little while ago asking for
opinions from people using SA1100. There was one reponse from Nico who
believes that the SA1100 is the same as the PXA255 in this respect.
You also asked me to involve the watchdog maintainer which I tried to
do but didn't hear anything back. There are only a couple of other
drivers which can't stop the watchdog and there seems to be no
consistancy regarding printing an error etc. I decided to print
something since that matches the case for all the other drivers when
NOWAYOUT is turned on.
Also, I changed the device .name to "watchdog" like most of the other
watchdogs. udev uses it as the device name (by default) and spaces etc.
get in the way.
Superceded 2833/1 because 2.6.13-rc4 caused rejects.

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.

Removing the SCSI tape module results in an oops in class_device_destroy if
any devices are present. The patch at the end of this message fixes the bug
by moving class_destroy() later in exit_st() so that the class still exists
when devices are removed. (The bug is old but class_simple_device_remove() did
nothing when the class did not exist.)
The patch also fixes a "class leak" in init_st() error path.
I would like to get this into 2.6.13 but it may be too late?

- Fixed some bttv card numbers.
- BTTV and SAA7134 version numbers incremented to reflect changes.
- pci_dma_supported() is called after pci_set_dma_mask() which
already did check that for us. This patch removes the unneeded call to
pci_dma_supported() at bttv-driver.c
- Ensure a sufficient I2C bus idle time between 2 messages for
saa7134-i2c.c
- It is important to write at first to MO_GP3_IO for cx88-tvaudio.c
- Use try_to_freeze() instead of refrigerator at msp3400.c
- Recognizing the MFPE05-2 Tuner at tveeprom.c
- Add new parameter to help identify radio chipsets at tuner module:
show_i2c=1 will show 16 reading bytes from detected tuners.
- BTTV does generate some Unimplemented IOCTL log at tuner module:
0x40046d11(dir=1,tp=0x6d,nr=17,sz=4) means that it is sending
MSP3400 calls to non-msp3400 tuners. Warning eliminated.
VIDIOSAUDIO is also called, so debug messages updated. It is still
requiring IOCTL implementation.
- Added two more tuners.
- Add support for the SVideo input on the GDI Black Gold.

If there are devices that use interrupts over a suspend event, ACPI must
restore the PCI interrupt links on resume. Anything else breaks any
device that hasn't been converted to the new (dubious) PM rules.
Drivers that need the irq free/re-aquire sequence can be done one by one
independently of this one.
