This is the fourth part of the new ACPI based system device hotplug framework, which enhances the ACPI processor driver to support the ACPI system device hotplug framework. For an introduction of the new framework, please refer to: https://lkml.org/lkml/2012/11/3/143 https://github.com/downloads/jiangliu/linux/ACPI%20Based%20System%20Device%20Dynamic%20Reconfiguration.pdf And you may pull from: https://github.com/jiangliu/linux.git acpihp_processor This patch set changes the existing ACPI processor driver to support new hotplug framework as below: 1) remove code to handle hotplug events from processor driver 2) add callbacks to support new hotplug framework 3) some minor fixes/cleanups Jiang Liu (9): ACPI/processor: remove dead code from processor_driver.c ACPIHP/processor: reorganize ACPI processor driver for new hotplug framework ACPIHP/processor: protect accesses to device->driver_data ACPIHP/processor: enhance processor driver to support new hotplug framework CPU: introduce busy flag to temporarily disable CPU online sysfs interface ACPIHP/processor: reject online/offline requests when doing processor hotplug ACPI/processor: cache parsed APIC ID in processor driver data structure ACPI/processor: serialize call to acpi_map/unmap_lsapic x86: simplify _acpi_map_lsapic() implementation arch/ia64/include/asm/cpu.h | 2 +- arch/ia64/kernel/acpi.c | 38 +-- arch/ia64/kernel/topology.c | 10 +- arch/x86/include/asm/cpu.h | 2 +- arch/x86/include/asm/mpspec.h | 2 +- arch/x86/kernel/acpi/boot.c | 82 +----- arch/x86/kernel/apic/apic.c | 8 +- arch/x86/kernel/topology.c | 10 +- drivers/acpi/Kconfig | 11 +- drivers/acpi/internal.h | 2 + drivers/acpi/processor_core.c | 28 +- drivers/acpi/processor_driver.c | 551 ++++++++++++++++++--------------------- drivers/base/cpu.c | 22 ++ drivers/xen/cpu_hotplug.c | 2 +- include/acpi/processor.h | 3 + include/linux/acpi.h | 2 +- include/linux/cpu.h | 2 + 17 files changed, 342 insertions(+), 435 deletions(-) -- 1.7.9.5 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
