Fix "lost" interrupt problem when using dma with CD/DVD drives in some
configurations. This problem can make installing linux from media
impossible for distro's that have switched to libata-only configurations.
The simple fix is to eliminate the use of dma for reading drive status, etc,
by checking the number of bytes to transferred.
This change will only affect the behavior of atapi devices, not disks.

This patch corrects sata_promise to classify FastTrack TX4200
(DID 3515/3519) as a second-generation chip. Promise's partial-
source FT TX4200 driver confirms this classification.
Treating it as a first-generation chip causes several problems:
1. Detection failures. This is a recent regression triggered by
the hotplug-enabling changes in 2.6.23-rc1.
2. Various "failed to resume link for reset" warnings.
This patch fixes <http://bugzilla.kernel.org/show_bug.cgi?id=8936>.

Previously I reported that the pata_pdc2027x PLL detection changes
in kernel 2.6.22 broke the driver on my PowerMac:
>pata_pdc2027x: Invalid PLL input clock 1691742kHz, give up!
This is followed by a number of errors and speed reduction
steps on the affected ports.
There are two bugs in pata_pdc2027x's PLL detection code:
1. The PLL counter's start value is read before the chip is
put in "test mode". Outside of test mode the counter is
halted, and on the PowerMac the counter is zero because
the chip hasn't been initialised by its BIOS.
The fix is to move the read of the start value to after
test mode is started, but before the mdelay() in test mode.
This also improves the precision of the PLL detection.
2. The code to compute the number of PLL decrements during the
mdelay() in test mode fails to consider that the PLL counter
only is 30 bits wide. If there is a wraparound, it will compute
an incorrect and much too large value. On the PowerMac, the
start count is zero, the end count is a large 30-bit value, so
wraparound occurs and an out of bounds PLL clock is detected.
The fix is to mask the (start - end) computation to 30 bits.
While debugging this I also noticed that pdc_read_counter()
reads the two halves of the 30-bit PLL counter as 16-bit values,
and then combines them as if the halves only are 15 bits wide.
To avoid confusion, the halves should be read as 15-bit values.
This patch implements all three changes. It fixes the PLL detection
failure on my PowerMac, and doesn't cause any regressions on an x86
with an identical card.

Fix several inconsistencies in these drivers WRT reporting the clocks:
- when using DPLL mode, 'pata_hpt37x' driver reported the DPLL frequency as the
PCI clock -- make it properly report both clocks and add the same ability to
the 'pata_hpt3x2n' driver;
- both drivers sometimes use "pata_hpt3*:" and sometimes "hpt3*:" in the
messages -- make them use only the former one;
- the message about failed DPLL stablizatios deserves KERN_ERR and a bang. :-)

The DPLL tuning code always set up it for 66 MHz due to wrong UltraDMA mask
including mode 5 used to check for the necessity of 66 MHz clocking -- this
caused 66 MHz clock to be used for HPT374 chip that does not tolerate it.
While fixing this, also remove PLL mode from the TODO list -- I don't think
it's still a relevant item.

Alan Cox suggested that the solution to the FIXMEs in pata_icside is
to use a private postreset method to detect the lack of devices on a
port, and in such a case, disable the interrupt for the port.
This patch implements such a method, and removes the hard coded
disable of port 0. Tested as working.

* Fix MWDMA timings setup in sis_old_set_dmamode() and sis_66_set_dmamode().
The old timings were overclocked (even worse behavior than sis5513 IDE driver
which depends on BIOS to program correct timings), the new timings are taken
from the datasheet (they match timings from ATA spec).
* Fix UDMA timings setup in sis_old_set_dmamode().
Misplaced pci_write_config_word() call resulted in UDMA timings never
being set.
* Fix comments for sis_133_early_set_dmamode() and sis_133_set_dmamode():
- only the former function handles early SiS 961 bridges
- both functions lack MWDMA timings setup
* Fix typos in sis_100_set_piomode() and sis_133_set_piomode() comments.
* Bump driver version.

ACPI implementations in several TOSHIBA laptops are weird and burn cpu
cycles for tens of seconds while trying to suspend if the PCI device
for the ATA controller is disabled when the ACPI suspend is called.
This patch uses DMI to match those machines and bypass device disable
on those machines during suspend. As the device needs to be put into
enabled state on resume without affecting PCI enable count, matching
resume callback uses __pci_reenable_device().
This bug is reported in bugzilla bug 7780.

In most cases, when EH is scheduled, all in-flight commands are
aborted causing EH to kick in immediately. However, in some cases
(especially with PMP), it's unclear which commands are affected by the
error condition and although aborting all in-flight commands work, it
isn't optimal and may cause unnecessary disruption. On the other
hand, waiting for in-flight commands to drain themselves can take up
to 30seconds.
This patch implements EH fast drain to handle such situations. It
gives in-flight commands some time to finish up but doesn't wait for
too long. After EH is scheduled, fast drain timer is started and if
no other completion occurs in ATA_EH_FASTDRAIN_INTERVAL all in-flight
commands are aborted. If any completion occurred in the interval, the
port is given another interval to finish up itself.
Currently ATA_EH_FASTDRAIN_INTERVAL is 3 secs which should be enough
for finishing up most commands.

ATA_EHI_HOTPLUGGED is a hint for reset functions indicating the the
port might have gone through hotplug/unplug just before entering EH.
Reset functions modify their behaviors a bit to handle the situation
better - e.g. using longer debouncing delay.
Currently, once HOTPLUG is set, it isn't cleared till the end of EH.
This is unnecessary and makes EH take longer. Clear the HOTPLUGGED
flag after a reset try (successful or not).
