Ian Campbell 9bbd037589 [PATCH] ARM: 2833/2: Remove support for WDIOF_MAGICCLOSE from sa1100-wdt
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Superceded 2833/1 because 2.6.13-rc4 caused rejects.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

Linus Torvalds 688d191821 pci: make bus resource start address override minimum IO address
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.

Jens Axboe d7ed538a02 [PATCH] cfq-iosched: fix problem with barriers and max_depth == 1
CFQ will currently stall when using write barriers and the default

Paul Mackerras f7d1d23c30 [PATCH] Obvious bugfix for yenta resource allocation
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.

Kai Makisara c2c96f46f4 [SCSI] Fix SCSI tape oops at module removal
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.

Mauro Carvalho Chehab fd3113e84e [PATCH] V4L: Miscellaneous fixes
- 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.

Antonino A. Daplas 8d894c4797 [PATCH] tridentfb: Fix scrolling artifacts during disk IO
Reported by: Jochen Hein (Bugzilla Bug 4312)

When there is disk I/O happening, the framebuffer has a little snow on
the screen.  Once I/O has finished, no garbage remains on screen.

This bug was explained by: Knut Petersen

Most important is CRTC register 2f, signal quality is also improved for
higher vclk values by changing set_vclk() according to the X drivers and
cyblafb.c

The fix is to set the performance register (0x2f) with a more stable
value.

Antonino A. Daplas 8dad46cf38 [PATCH] tridentfb: Fix scrolling artifacts if acceleration is enabled
Reported by: Jochen Hein (Bugzilla Bug 4386)

booting leaves the end of long lines in the last line on screen when
scrolling.  When X is running, scrolling puts garbage on the screen
(looks like X data) Console switch fixes the screen.  Behaviour seems to
be identical with noaccel and without on the video=tridentfb parameter
in lilo.conf.

This bug was explained by: Knut_Petersen

Acceleration is broken for all BLADE 3D chips for all versions of kernel
2.6 except for 32bit modes.  Most important reason is that the u32 col
parameter of the graphics engine needs the color value replicated to all
u8 of the u32 (8bit modes) and to both u16 of the u32.

Matthew Garrett b0825488a6 [PATCH] agp: restore APBASE after setting APSIZE
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.

Without this patch, I get the symptoms described in bug 4921 - APBASE ends
up overlapping various PCI devices, and as a result they fail to work after
resume.

Range is already set to write-back, vesafb attempts to add a write-combining

>> mtrr: size and base must be multiples of 4 kiB

This is a bug, vesafb attempts to add a size < PAGE_SIZE triggering

To eliminate the warning messages, you can add the option mtrr:2 to add a
write-back mtrr for vesafb.  Or just use nomtrr option.

1. Fix algorithm for finding the best power of 2 size with mtrr_add().

2. Add option to choose the mtrr type by extending the mtrr boot option:

   mtrr:n where n

        0 = no mtrr (equivalent to using the nomtrr option)
        1 = uncachable

The setup-bus code doesn't work correctly for configurations
with more than one display adapter in the same PCI domain.
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.

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).

Alasdair G Kergon 2ca3310e78 [PATCH] device-mapper: fix md->lock deadlocks in core
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.
