Merge tag 'pci-v3.14-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI updates from Bjorn Helgaas:
"The most interesting thing here is the change to enable INTx (by
clearing PCI_COMMAND_INTX_DISABLE) if the BIOS left INTx disabled.
Apparently the Baytrail BIOS does this, which means EHCI doesn't work.
Also, fix an AHCI MSI regression and other issues with the recent MSI
changes. This also adds pci_enable_msi_exact() and
pci_enable_msix_exact(), which aren't regression fixes, but will keep
us from touching drivers twice (once to stop using the deprecated
pci_enable_msi(), etc., and again to use the *_exact() variants).
There's also a minor MVEBU fix.

The new pci_msi_vec_count() interface makes pci_enable_msi_block_auto()
superfluous.
Drivers can use pci_msi_vec_count() to learn the maximum number of MSIs
supported by the device, and then call pci_enable_msi_block().
pci_enable_msi_block_auto() was introduced recently, and its only user is
the AHCI driver, which is also updated by this change.

The check for "combined mode" (which disables ahci support) on ICH6 is
done after the first use of AHCI BAR. But if ahci is not enabled AHCI
BAR is initialized to 0x00000000. (At least it is on the ICH6-M I tested
this on. If I understand the datasheet correctly it should also be on
ICH6R.) This apparently makes the call of
pcim_iomap_regions_request_all() return -EINVAL. And we end up with
ahci: probe of 0000:00:1f.2 failed with error -22
(at warning level) in the logs.
So check for "combined mode" before calling
pcim_iomap_regions_request_all().

libata/for-3.10-fixes never got submitted during v3.10 cycle. Merge
it into for-3.11 so that it can be routed together with other changes
scheduled for v3.11.
Three trivial conflicts in drivers/ata/sata_rcar.c. All are caused by
1b20f6a9ad ("sata_rcar: add 'base' local variable to some functions")
conflicting with logic updates in for-3.10-fixes. The offending
commit simply adds local variable @base on functions which
dereferences sata_rcar_priv->base multiple times. The resolutions are
trivial - applying s/priv->base/base/ in the conflicting logic
updates.

Take advantage of multiple MSIs implementation on x86 - on
systems with IRQ remapping AHCI ports not only get assigned
separate MSI vectors - but also separate IRQs. As result,
interrupts generated by different ports could be serviced on
different CPUs rather than on a single one.
In cases when number of allocated MSIs is less than requested
the Sharing Last MSI mode does not get used, no matter
implemented in hardware or not. Instead, the driver assumes the
advantage of multiple MSIs is negated and falls back to the
single MSI mode as if MRSM bit was set (some Intel chips
implement this strategy anyway - MRSM bit gets set even if the
number of allocated MSIs exceeds the number of implemented ports).

They don't always appear as AHCI class devices but instead as IDE class.

This can also appear as 0x9192. Reported in bugzilla and confirmed with the

The JMicron JMB362 controller supports AHCI only, but some revisions
use the IDE class code. These need to be matched by device ID.
These additions have apparently been included by QNAP in their NAS
devices using these controllers.

This patch converts the drivers in drivers/ata/* to use module_pci_driver()
macro which makes the code smaller and a bit simpler.

Like e65cc194f7 (ahci: Enable SB600 64bit
DMA on MSI K9A2 Platinum) and 3c4aa91f21
(ahci: Enable SB600 64bit DMA on Asus M3A), this patch enables 64bit DMA
for the AHCI SATA controller of another board that has the SB600
southbridge.
In this case though we're enabling 64bit DMA for another MSI motherboard,
the K9AGM2 or MS-7327. It is new enough that all of the BIOS releases
since the initial release (1.0 from 2007-02-09) work correctly with 64bit
DMA enabled.

The AHCI controller found in the STA2X11 chip uses BAR number 0
instead of 5. Also, the chip's fixup code sets a special DMA mask
for all of its PCI functions, and the mask must be preserved here.
