Could you please elaborate what it means by fake _OST method? I am assuming based on the above that this patch set was never tested on real hardware that has support for _OST method? Is that correct? If so why not wait until you have the opportunity to test it on real hardware before sending the patch? -- Shuah > > --- > Toshi Kani (4): > ACPI: Set hotplug _OST support bit to _OSC > ACPI: Add acpi_evaluate_ost() for calling _OST > ACPI: Add _OST support for ACPI CPU hotplug > ACPI: Add _OST support for ACPI memory hotplug > > drivers/acpi/acpi_memhotplug.c | 43 +++++++++++++++++++++++++++++---------- > drivers/acpi/bus.c | 5 ++++ > drivers/acpi/processor_driver.c | 28 ++++++++++++++++++------- > drivers/acpi/utils.c | 34 ++++++++++++++++++++++++++++++ > include/acpi/acpi_bus.h | 3 ++ > include/linux/acpi.h | 26 ++++++++++++++++++++++- > 6 files changed, 119 insertions(+), 20 deletions(-) > > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ >
