Currently, ahci supports only msi and intx. To also support msix the
handling of the irq number need to be changed. The irq number for msix
devices is taken from msi_list instead of pci_dev. Thus, the irq
number of a device needs to be stored in struct ahci_host_priv now.
This allows the host controller to be activated in a generic way.This change is only intended for ahci drivers. For that reason the irq
number is stored in struct ahci_host_priv used only by ahci drivers.
Thus, the ABI changes only for ahci_host_activate(), but existing ata
drivers (about 50) are unaffected and keep unchanged. All users of
ahci_host_activate() have been updated.While touching drivers/ata/libahci.c, doing a small code cleanup in
ahci_port_start().Signed-off-by: Robert Richter

Currently host activation done by calling either function
ahci_host_activate() or ata_host_activate(). Consolidate
the code by only calling ahci_host_activate() for all AHCI
devices.Signed-off-by: Alexander Gordeev

This patch moves force_port_map and mask_port_map into the
ahci_host_priv structure. This allows to modify them into the AHCI
framework. This is needed by the new dt bindings representing ports as
the port_map mask is computed automatically.Parameters modifying force_port_map, mask_port_map and flags have been
removed from the ahci_platform_init_host() function, and inputs in the
ahci_host_priv structure are now directly filed.Signed-off-by: Antoine Ténart

This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM
where applicable. Benefits of this change:* unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n
and CONFIG_PM_RUNTIME=y configurations* easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in
the future* more consistent code (there are host drivers which are using the correct
CONFIG_PM_SLEEP checks already)The patch leaves the core libata code and ->port_[suspend,resume] support
in sata_[inic162x,nv,sil24].c alone for now.Signed-off-by: Bartlomiej Zolnierkiewicz

None of these files are actually using any __init type directives
and hence don't need to include . Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.Cc: linux-ide@vger.kernel.org

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.Signed-off-by: Tejun Heo

Use the wrapper function for getting the driver data using pci_dev
instead of using dev_get_drvdata() with &pdev->dev, so we can directly
pass a struct pci_dev. This is a purely cosmetic change.Signed-off-by: Jingoo Han
