The HPT36x chips finally turned out to have the channel enable bits -- however,
badly implemented. Make use of them despite it's probably only going to burden
the driver's code -- assuming both channels are always enabled by the HighPoint
BIOS anyway...

Look at wait_drive_not_busy in drivers/ide/ide-taskfile.c:
static u8 wait_drive_not_busy(ide_drive_t *drive)
{
ide_hwif_t *hwif = HWIF(drive);
int retries = 100;
u8 stat;
/*
* Last sector was transfered, wait until drive is ready.
* This can take up to 10 usec, but we will wait max 1 ms
* (drive_cmd_intr() waits that long).
*/
while (((stat = hwif->INB(IDE_STATUS_REG)) & BUSY_STAT) && retries--)
udelay(10);
if (!retries)
printk(KERN_ERR "%s: drive still BUSY!\n", drive->name);
return stat;
}
`printk' is never called because `retries' never holds zero at the
outside of `while' loop: when `retries' holds zero at the while's loop
condition, `retries' will hold -1 at the if condition.

host->irq and host->irq2 should be set before ata_host_register() for
IRQ reporting to work. Move up host->irq assignment in
ata_host_activate() and add it to ata_pci_init_one() native path and
pata_cs5520.
The port info printing in ata_host_register() doesn't fit all the
different controllers. It should probably be moved out to LLDs with
some helpers in the future.

If a page can't be allocated for the frag list of a skb, the code to
unmap the partially allocated list is off by one. For exaple, if
'frags' equals one, i == 0, and the alloc_page() fails, then the old
loop would have unmapped mapping[1] which is uninitialized. The same
would happen if the call to ib_dma_map_page() failed.

Changed PATA handler for PATA-ports used by sata_sis.
This patch was originally submitted by Jeff Garzik.
Added PCI-ID 1180 for SiS966 Controller in pata_sis.
The 1180 mode is fully compatible to other SiS PATA-controller.
The PCI-ID 1183 is SATA in PATA-emulation, but not fully compatible
to SiS5513/5518. sata_sis.c is forwarding this ID to pata_sis.
1183 is not working if simply added to pata_sis.
This handling fixes issues with SiS968.

Recently the PLL input clock of pata_pdc2027x is sometimes detected
higer than expected (e.g. 20.027 MHz compared to 16.714 MHz).
It seems sometimes the mdelay() function is not as precise as it
used to be. Per Alan's advice, HT or power management might affect
the precision of mdelay().
This patch calls gettimeofday() to mesure the time elapsed and
calculate the PLL input clock accordingly.

Don't use PNP detection by default yet. We have some PNP and BIOS issues
to work out first.
Sample problem on a Toshiba Portege 4000: the SMCf010 device is handed off
disabled. We assign I/O ports originally assigned to the SMCf010 to a
PCMCIA device instead. We enable the SMCf010, configuring it to use
disjoint ports, but _SRS doesn't work correctly, so the device doesn't
work.

If asus_acpi_init doesn't find any device it knows about, it mistakenly
returns a "success" error code even though it cleans up after itself. Later
when trying to rmmod asus_acpi, the module_exit routine would try to clean up
one more time and we would end up calling
acpi_bus_unregister_driver(&asus_hotk_driver) twice. This patch addresses
this first problem by returning -ENODEV when no appropriate device is found.
Then there was also another bug with the code handling the return value of
backlight_device_register. If this function ever failed, the driver would
cleanup by calling the module_exit routine from module_init, but it would
still return "success". So any attempt to rmmod this module would result in
asus_acpi_exit being called twice but it's not ready to handle it (I haven't
hit this bug, just found it by code inspection). This patch fixes that by
inserting a return -ENODEV; at the end of this error handling path.

The interrupt clearing code in mpsc_sdma_intr_ack() mistakenly clears the
interrupt for both controllers instead of just the one its supposed to.
This can result in the other controller appearing to hang because its
interrupt was effectively lost.
So, don't clear the interrupt cause bits for both MPSC controllers when
clearing the interrupt for one of them. Just clear the one that is
supposed to be cleared.
