The code really means to mask off the high bits, not assign 0xff.

During an STR resume cycle, the ide master disk times-out when there is
also a slave present (especially CD).  Increasing the timeout in ide-io
from 10,000 to 100,000 fixes this problem.

Something is wrong with the 3-multiply (vs. 4-multiply) optimized
version of _FP_MUL_MEAT_2_*(), so just use the slower version
which actually computes correct values.

The i386 defconfig wasn't updated for ages.

Instead of running "make oldconfig" on the old defconfig and trying to
give reasonable answers at all new options, this patch replaces it with
the one I'm using in 2.6.16-rc1.

This way, it's a .config that is confirmed to work on at least one
computer in the world.  ;-)

At least Maxtor OneTouch III require a "start stop unit" command after
auto spin-down before the next access can proceed.  This patch activates
the responsible code in scsi_mod for all Maxtor SBP-2 disks.

Maybe that should be done for all SBP-2 disks, but better be cautious.

I've been experimenting to track down the cause of suspend/resume problems
on my Compaq Presario X1050 laptop:

http://bugzilla.kernel.org/show_bug.cgi?id=6075

Essentially the ACPI Embedded Controller and keyboard controller would
get into a bizarre, confused state after resume.

I found that unloading the ohci1394 module before suspend and reloading it
after resume made the problem go away.  Diffing the dmesg output from
resume, with and without the module loaded, I found that with the module
loaded I was missing these:

PM: Writing back config space on device 0000:02:00.0 at offset 1. (Was 2100080, writing 2100007)
PM: Writing back config space on device 0000:02:00.0 at offset 3. (Was 0, writing 8008)
PM: Writing back config space on device 0000:02:00.0 at offset 4. (Was 0, writing 90200000)
PM: Writing back config space on device 0000:02:00.0 at offset 5. (Was 1, writing 2401)
PM: Writing back config space on device 0000:02:00.0 at offset f. (Was 20000100, writing 2000010a)

The default PCI driver performs the pci_restore_state when no driver is
loaded for the device.  When the ohci1394 driver is loaded, it is supposed
to do this, however it appears not to do so.

I created the patch below and tested it, and it appears to resolve the
suspend problems I was having with the module loaded.  I only added in the
pci_save_state and pci_restore_state - however, though I know little of
this hardware, surely the driver should really be doing more than this when
suspending and resuming?  Currently it does almost nothing, what if there
are commands in progress, etc?
