From 71bba8fafac8975dbb684df4098d2dd6baac1fda Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 7 Nov 2013 01:40:50 +0100 Subject: ACPI: Remove acpi_pci_slot_init() headers from internal.h Since acpi_pci_slot_init() is now called from acpi_pci_init() and pci-acpi.h contains its header, remove that header (and the empty definition of that function for CONFIG_ACPI_PCI_SLOT unset) from internal.h as it doesn't have to be there any more. That also avoids a build warning about duplicate function definitions for CONFIG_ACPI_PCI_SLOT unset. Signed-off-by: Rafael J.

Wysocki" Date: Thu, 7 Nov 2013 01:42:09 +0100 Subject: ACPI / hotplug: Carry out PCI root eject directly Since _handle_hotplug_event_root() is run from the ACPI hotplug workqueue, it doesn't need to queue up a work item to eject a PCI host bridge on the same workqueue. Instead, it can just carry out the eject by calling acpi_bus_device_eject() directly, so make that happen. Signed-off-by: Rafael J.

Wysocki" Date: Thu, 7 Nov 2013 01:45:40 +0100 Subject: ACPI / hotplug: Consolidate deferred execution of ACPI hotplug routines There are two different interfaces for queuing up work items on the ACPI hotplug workqueue, alloc_acpi_hp_work() used by PCI and PCI host bridge hotplug code and acpi_os_hotplug_execute() used by the common ACPI hotplug code and docking stations. They both are somewhat cumbersome to use and work slightly differently. The users of alloc_acpi_hp_work() have to submit a work function that will extract the necessary data items from a struct acpi_hp_work object allocated by alloc_acpi_hp_work() and then will free that object, while it would be more straightforward to simply use a work function with one more argument and let the interface take care of the execution details. The users of acpi_os_hotplug_execute() also have to deal with the fact that it takes only one argument in addition to the work function pointer, although acpi_os_execute_deferred() actually takes care of the allocation and freeing of memory, so it would have been able to pass more arguments to the work function if it hadn't been constrained by the connection with acpi_os_execute(). Moreover, while alloc_acpi_hp_work() makes GFP_KERNEL memory allocations, which is correct, because hotplug work items are always queued up from process context, acpi_os_hotplug_execute() uses GFP_ATOMIC, as that is needed by acpi_os_execute(). Also, acpi_os_execute_deferred() queued up by it waits for the ACPI event workqueues to flush before executing the work function, whereas alloc_acpi_hp_work() can't do anything similar. That leads to somewhat arbitrary differences in behavior between various ACPI hotplug code paths and has to be straightened up. For this reason, replace both alloc_acpi_hp_work() and acpi_os_hotplug_execute() with a single interface, acpi_hotplug_execute(), combining their behavior and being more friendly to its users than any of the two.
