In the event that any one of the DAC analog outputs (R,G,B) were driven
at full-scale (white video) or some analog level close to full-scale
voltage, and if the video cable were then disconnected, the analog video
voltage level would exceed the maximum electrical overstress limit of the
native (thin-oxide) transistors thus causing a long-term reliability concern.
The electrical overstress condition occurs in this particular case.

This patch address the IGD EOS (electrical overstress condition) issue.
When the EOS interrupt occurs, OS should disable DAC and then disable EOS,
then the normal hotplug operation follows.

TODO: it appears the normal unplug interrupt is missed as reported by Li Peng,
need more checks here.

Currently SDVO TV only support NTSC-M format. In this patch
we introduce PAL and SECAM formats available and create seting-format
property at init time. When user dynamically chose preferred
format by xrandr command, it will refine all modelines
provided by SDVO device, then instruct SDVO device to execute.
At the same time the property is added for SDVO-TV so that the SDVO-TV mode can be changed
by using xrandr.

For integrated TV there are 3 connector types: S-VIDEO, Composite and
Component(YprPb). Those tv formats whose component flag is true should
be assigned to Component connector, others are for S-VIDEO and Composite.
The patch intends to find appropriate tv format for each connector.
In such case it will return the correct modeline to user space. Otherwise
it will return the incorrect modeline when S-video/composite is connected.

Some i915/i945 platforms have a fairly high memory latency in certain
situations, so increase our constant a bit to avoid FIFO underruns.
The effect should be positive on other platforms as well; we'll have a
bit more insurance against a busy memory subsystem due to the extra
FIFO entries.

Commit log for commit 517d3cc1
("[libata] ata_piix: Enable parallel scan") says:

    This patch turns on parallel scanning for the ata_piix driver.
    This driver is used on most netbooks (no AHCI for cheap storage it seems).
    The scan is the dominating time factor in the kernel boot for these
    devices; with this flag it gets cut in half for the device I used
    for testing (eeepc).
    Alan took a look at the driver source and concluded that it ought to be safe
    to do for this driver.  Alan has also checked with the hardware team.

and it is all true but once we put all things together additional
constraints for PATA controllers show up (some hardware registers
have per-host not per-port atomicity) and we risk misprogramming
the controller.

I used the following test to check whether the issue is real:

  @@ -736,8 +736,20 @@ static void piix_set_piomode(struct ata_
   			(timings[pio][1] << 8);
   	}
   	pci_write_config_word(dev, master_port, master_data);
  -	if (is_slave)
  +	if (is_slave) {
  +		if (ap->port_no == 0) {
  +			u8 tmp = slave_data;
  +
  +			while (slave_data == tmp) {
  +				pci_read_config_byte(dev, slave_port, &tmp);
  +				msleep(50);
  +			}
  +
  +			dev_printk(KERN_ERR, &dev->dev, "PATA parallel scan "
  +				   "race detected\n");
  +		}
   		pci_write_config_byte(dev, slave_port, slave_data);
  +	}

   	/* Ensure the UDMA bit is off - it will be turned back on if
   	   UDMA is selected */

and it indeed triggered the error message.

Lets fix all such races by adding an extra locking to ->set_piomode
and ->set_dmamode methods for PATA controllers.

[ Alan: would be better to take the host lock in libata-core for these
  cases so that we fix all the adapters in one swoop.  "Looks fine as a
  temproary quickfix tho" ]

The lack of a proper LRU was partially worked around by taking the fence
from the object containing the oldest seqno.  But if there are multiple
objects inactive, then they don't have seqnos and the first fence reg
among them would be chosen.  If you were trying to copy data between two
mappings, this could result in each page fault stealing the fence from
the other argument, and your application hanging.

-tip testing found that this patch breaks the build on x86 if
CONFIG_KALLSYMS is disabled:

 kernel/module.c: In function ‘load_module’:
 kernel/module.c:2367: error: ‘struct module’ has no member named ‘sect_attrs’
 distcc[8269] ERROR: compile kernel/module.c on ph/32 failed
 make[1]: *** [kernel/module.o] Error 1
 make: *** [kernel] Error 2
 make: *** Waiting for unfinished jobs....

Commit 1b364bf4 misses the fact that section attributes are only
built and dealt with if kallsyms is enabled. The patch below fixes
this.

( note, technically speaking this should depend on CONFIG_SYSFS as
  well but this patch is correct too and keeps the #ifdef less
  intrusive - in the KALLSYMS && !SYSFS case the code is a NOP. )
