      Fix simplex adapters with libata · 14d66ab7
      Petr Vandrovec authored 
      Recently I got my hands on nVidia's MCP61 PM-AM board, and
it contains IDE chip configured by BIOS with only primary
channel enabled.  This confuses code which probes for
device DMA capabilities - it gets 0x60 (happy duplex
device) from primary channel BMDMA, but 0xFF (nobody here)
from secondary channel BMDMA.  Due to this code then believes
that chip is simplex.  I do not address this problem in
my patch, as I'm not sure how to handle this.  Probably
ata_pci_init_one should have bitmap of enabled/possible
interfaces instead of their count, but it looks like
quite intrusive change, and maybe we do not care - for device
with only one channel simplex and regular DMA engines are
same.

But making device simplex pointed out that support for
DMA on simplex devices is currently broken - ata_dev_xfermask
tests whether device is simplex and if it is whether DMA
engine was assigned to this port.  If not then it strips
out DMA bits from device.  Problem is that code which assigns
DMA engine to port in ata_set_mode first detect device
mode and assigns DMA engine to channel only if some DMA
capable device was found.

And as xfermask stripped out DMA bits, host->simplex_claimed
is always NULL with current implementation.

By allowing DMA either if simplex_claimed is NULL or if it
points to current port DMA can be finally used - it gets
assigned to first port which contains any DMA capable
device.

      ata_piix: Remove ugly layering violation · 9a2eb709
      Alan Cox authored 
      A while ago I modified the libata code so that drivers can return -ENOENT
for unknown ports not fiddle with the EH flags and print stuff directly.
Somewhere along the line ata_piix didn't get fully converted.

      [PATCH] ACPI: repair nvidia early quirk breakage on x86_64 · fe699336
      Len Brown authored 
      x86_64 nvidia_bugs() broke when we bailed out on not finding the HPET.
However, the quirk works by checking for _not_ finding the HPET...

Delete the nvidia_hpet_detected flag and simply test for
not finding the HPET, which is simple to do now that
acpi_table_parse returns 1 on failure.
