Hi All, Now the series has been rebased on top of current linux-pm.git/linux-next and tested on two systems with Thunderbolt. Some changes have been made too. -> On Friday, July 12, 2013 01:34:20 AM Rafael J.

The numbering of the patches below has changed as a result, so the next one is [13/30] now and so on. > [14/30] Drop flags field from struct acpiphp_bridge. > [15/30] Embed function structure into struct acpiphp_context. > [16/30] Drop handle field from struct acpiphp_func. > [17/30] Drop handle field from struct acpiphp_bridge. > [18/30] Store parent bridge pointer in function objects and bus pointer in slot > objects. > [19/30] Rework ACPI namespace scanning and trimming routines. > [20/30] Drop redundant checks from check_hotplug_bridge(). > [21/30] Consolidate slot disabling and ejecting > [22/30] Do not queue up event handling work items for non-hotplug events. > [23/30] Do not execute _PS0 and _PS3 directly.

[Thunderbolt series] > [26/30] Check for new devices on enabled slots. [Thunderbolt series, TBD] This one was reworked to use acpi_bus_trim() on ACPI device objects corresponding to PCI devices being removed (it also uses _STA to check the status of those devices if available). > [27/30] Get rid of unused constands in acpiphp.h. [Thunderbolt series] > [28/30] Sanitize acpiphp_get_(latch)|(adapter)_status(). [Thunderbolt series] > [29/30] Redefine enable_device() and disable_device() (rename and change to void). > [30/30] Clean up the usage of bridge_mutex. The one above is [29/30] now and we have added one more patch: [30/30] Drop check_sub_bridges() which isn't necessary any more. The updated patches follow. If you don't hate this stuff, I'll put it into linux-next over the weekend for further testing. Thanks, Rafael -- I speak only for myself. Rafael J.
