ACPI: Remove FSF mailing addresses

2015-07-08T00:27:32Z

There is no need to carry potentially outdated Free Software Foundation mailing address in file headers since the COPYING file includes it. Signed-off-by: Jarkko Nikula Signed-off-by: Rafael J. Wysocki

cpuidle: ACPI: do not overwrite name and description of C0

2015-04-03T11:18:25Z

Fix a bug that leads to showing the name and description of C-state C0 as "" in sysfs after the ACPI C-states changed (e.g. after AC->DC or DC->AC transition). The function poll_idle_init() in drivers/cpuidle/driver.c initializes the state 0 during cpuidle_register_driver(), so we better do not overwrite it again with '\0' during acpi_processor_cst_has_changed().

ACPI / idle: Implement ->enter_freeze callback routine

2015-02-15T18:40:10Z

Add an ->enter_freeze callback routine, acpi_idle_enter_freeze(), to the ACPI cpuidle driver and point ->enter_freeze to it for all the C2-type and C3-type states that don't need to fall back to C1 (which may be halt-induced and that will re-enable interrupts on exit from idle, which ->enter_freeze cannot do).

ACPI / cpuidle: Common callback routine for entering states

2015-02-03T20:55:11Z

Introduce a common ->enter callback routine for the ACPI cpuidle driver, acpi_idle_enter(), which helps to reduce code complexity, size and duplication and prevents theoretically possible failues that an incorrect routine may be run to enter the given idle state due to a firmware bug (eg. when _CST returns a different set of states for each processor).

ACPI / cpuidle: Merge acpi_idle_enter_c1() and acpi_idle_enter_simple()

2015-02-03T20:54:48Z

acpi_idle_enter_c1() and acpi_idle_enter_simple() are close enough to each other that they can be merged into one function which reduces duplication of code quite a bit. Signed-off-by: Rafael J. Wysocki

ACPI / cpuidle: Drop flags.bm_check tests from acpi_idle_enter_bm()

2015-02-02T22:56:03Z

Since acpi_idle_enter_bm() is only used if flags.bm_check is set for the given acpi_processor object, it doesn't make sense to check that flag in there. For this reason, drop flags.bm_check tests (and some code depending on them) from acpi_idle_enter_bm(). Signed-off-by: Rafael J. Wysocki
