The driver used the channel not the device number for deciding where to
load some timing parameters. Also change so that we clear the UDMA field
as the old driver did. Not believed neccessary but does no harm.

LPM seems to get hung up while disabling DIPM, and after thinking
about this a bit, I don't think we really need to manually disable it
anyway.

This code relied on the CPU and GPU address for the aperture being the same,
On some r5xx hardware I was playing with I noticed that this isn't always true.
This fixes issues seen on some r400 cards. (bugs.freedesktop.org 9957)

I have a system here that actively relies upon RTC wake alarms, and it
has been failing (again) for a few days when attempting to use the
/sys/class/rtc/rtc?/wakealarm interface.
The old (fixed by Linus) /proc/ interface still works, but I'd like to
get it using the new one.
This patch fixes rtc-cmos to ignore the two upper bits when reading the
BCD mday (day of month) register from CMOS. Some systems (eg. mine)
seem to have the top bit set to "1" for some reason.
The older /proc/ interface ignores the upper bits, and so we should too.

There's nothing to be gained by configuring downstream links faster

libata EH used to ignore errors not associated with commands when
determining whether speed down is necessary or not. This leads to the
following problems.
* Errors not associated with commands can occur indefinitely without
libata EH taking corrective actions.
* Upstream link errors don't trigger speed down when PMP is attached
to it and commands issued to downstream device trigger errors on the
upstream link.
This patch makes ata_eh_link_autopsy() consider errors not associated
with command for speed down.

Reset failure is a critical error. It results in disabling the link
requiring user intervention to re-enable it. Make reset failure
handling more robust such that libata EH doesn't give up too early.
* Temporary glitches during hardreset may lead to classification
failure when there's no softreset available. Retry instead of
giving up.
* Initial softreset or follow up softreset may fail classification.
Move classification error handling block out of followup softreset
block such that both cases are handled and retry instead of giving
up. Also, on the last try, give ATA class a blind shot.

Commands sent to ATAPI tape drives via the SCSI generic (sg) driver are
limited in the amount of data that they can transfer by the max_sectors
value. The max_sectors value is currently calculated according to the
command set for disk drives, which doesn't apply to tape drives. The
default max_sectors value of 256 limits ATAPI tape drive commands to
128 KB. This patch against 2.6.24-rc1 increases the max_sectors value
for tape drives to 65535, which permits tape drive commands to transfer
just under 32 MB.
Tested with a SuperMicro PDSME motherboard, AHCI, and a Sony SDX-570V
SATA tape drive.
Note that some of the chipset drivers also set their own max_sectors
value, which may override the value set in libata-core. I don't have
any of these chipsets to test, so I didn't go messing with them. Also,
ATAPI devices other than tape drives may benefit from similar changes,
but I have only tape drives and disk drives to test.

The original workaround for the Promise ASIC PRD bug
contained an endianess bug which I failed to detect:
the adjustment of the last PRD entry's length field
applied host arithmetic to little-endian data, which
is incorrect on big-endian machines.
We have the length available in host-endian format, so
do the adjustment on host-endian data and then convert
and store it in the PRD entry's little-endian data field.
Thanks to an anonymous reviewer for detecting this bug.

The Jazz machines have to use the PIT timer for dyntick and highresolution

sg_mark_end() overwrites the page_link information, but all users want
__sg_mark_end() behaviour where we just set the end bit. That is the most
natural way to use the sg list, since you'll fill it in and then mark the
end point.
So change sg_mark_end() to only set the termination bit. Add a sg_magic
debug check as well, and clear a chain pointer if it is set.

Many mouse drivers are often compiled (e.g. in Linux distributions) into the
kernel at the same time just to make sure that at least one driver will suceed
in find it's mouse device. Nevertheless, only the inport and logitech busmouse
mouse drivers report with KERN_ERR log level if the mouse wasn't found. They
should use KERN_INFO instead, because it's not an error if the mouse isn't
