i2c: Add SMBus alert support
SMBus alert support. The SMBus alert protocol allows several SMBus
slave devices to share a single interrupt pin on the SMBus master,
while still allowing the master to know which slave triggered the
interrupt.
This is based on preliminary work by David Brownell. The key
difference between David's implementation and mine is that his was
part of i2c-core, while mine is split into a separate, standalone
module named i2c-smbus. The i2c-smbus module is meant to include
support for all SMBus extensions to the I2C protocol in the future.
The benefit of this approach is a zero cost for I2C bus segments which
do not need SMBus alert support. Where David's implementation
increased the size of struct i2c_adapter by 7% (40 bytes on i386),
mine doesn't touch it. Where David's implementation added over 150
lines of code to i2c-core (+10%), mine doesn't touch it. The only
change that touches all the users of the i2c subsystem is a new
callback in struct i2c_driver (common to both implementations.) I seem
to remember Trent was worried about the footprint of David'd
implementation, hopefully mine addresses the issue.

sata_via: Delay on vt6420 when starting ATAPI DMA write
When writing a disc on certain lite-on dvd-writers (also rebadged
as optiarc/LG/...) connected to a vt6420, the ATAPI CDB ends
up in the datastream and on the disc, causing silent corruption.
Delaying between sending the CDB and starting DMA seems to
prevent this.
I do not know if there are burners that do not suffer from
this, but the patch should be safe for those as well.
There are many reports of this issue, but AFAICT no solution was

The card is recognized and works with the deprecated ATA drivers.
The error I am seeing is:

I tracked it down to ata_id_is_cfa() in include/linux/ata.h.
The Delkin card has id[0] set to 0x844a and id[83] set to 0.
This isn't what the kernel expects and is probably incorrect.

Surprisingly, a slave drive works without this patch. According to the
datasheet, the controller by default derives the DMA mode from the
Set Features command issued to a drive. Not sure about the PIO
timings, though. The real problem is that the timings for the master
effectively are the ones tuned for the slave. If these support
different UDMA-settings, there is trouble, especially when the slave
supports a higher UDMA than the master.

libata: implement spurious irq handling for SFF and apply it to piix
Traditional IDE interface sucks in that it doesn't have a reliable IRQ
pending bit, so if the controller raises IRQ while the driver is
expecting it not to, the IRQ won't be cleared and eventually the IRQ
line will be killed by interrupt subsystem. Some controllers have
non-standard mechanism to indicate IRQ pending so that this condition
can be detected and worked around.
This patch adds an optional operation ->sff_irq_check() which will be
called for each port from the ata_sff_interrupt() if an unexpected
interrupt is received. If the operation returns %true,
->sff_check_status() and ->sff_irq_clear() will be cleared for the
port. Note that this doesn't mark the interrupt as handled so it
won't prevent IRQ subsystem from killing the IRQ if this mechanism
fails to clear the spurious IRQ.
This patch also implements ->sff_irq_check() for ata_piix. Note that
this adds slight overhead to shared IRQ operation as IRQs which are
destined for other controllers will trigger extra register accesses to
check whether IDE interrupt is pending but this solves rare screaming
IRQ cases and for some curious reason also helps weird BIOS related
glitch on Samsung n130 as reported in bko#14314.
http://bugzilla.kernel.org/show_bug.cgi?id=14314
* piix_base_ops dropped as suggested by Sergei.
* Spurious IRQ detection doesn't kick in anymore if polling qc is in
progress. This provides less protection but some controllers have
possible data corruption issues if the wrong register is accessed

pata_hpt3x2n: always stretch UltraDMA timing
The UltraDMA Tss timing must be stretched with ATA clock of 66 MHz, but the
driver only does this when PCI clock is 66 MHz, whereas it always programs
DPLL clock (which is used as the ATA clock) to 66 MHz.
