Subject: [PATCH v2 0/2] PCI/ACPI: Simplify PCIe _OSC feature negotiation

From: Joerg Roedel <jroedel@...e.de>

Hi,

here is the second version of my patch(es) to simplify the _OSC
negotiation of PCIe features between Linux and the firmware.

The main part is in patch 1, which removes the _OSC call for supported
features by merging it with the actuall _OSC call to negotiate the
features with the firmware.

This allows some simplifications of the code, notably the removal of
the acpi_pci_osc_support() function and the control=NULL special
casing in the acpi_pci_query_osc() function.

Please review.

Thanks,

	Joerg
