This contains 2 parts: 1-A) change acpi_status acpi_pci_query_osc() to take support and *control 1-B) introduce acpi_pci_osc_control_query() and I'd like to kill 1-B since it is removed soon by patch [10/10]. > > [2/10] - Introduce pci_aer_available() allowing the caller to check if the > AER service driver should be enabled. > > [3/10] - Introduce kernel command line switch pcie_ports=.

This also contains 2 parts: 8-A: don't use cached result 8-B: remove query in acpi_pci_osc_control_set() I think 8-B is not required since query relives in patch [10/10]. > > [9/10] - Reorder checks in acpi_pci_osc_control_set().

I think we should have this improved acpi_pci_osc_control_set() before [4/10]. > > Comments welcome. I recommend you to rearrange the order of patches in this series. 1. Misc cleanups [6/10] [9/10] 2. Prep1: prepare small parts [2/10] [3/10] 3. Prep2: improve acpi_pci_osc_control_set() [1-A] [8-A] [10/10] 4. Main [4/10] [5/10] I think there is no objections to 4 patches from the first ([6,9,2,3/10]).
