cpuidle: Invert CPUIDLE_FLAG_TIME_VALID logic

2014-11-12T20:17:27+00:00

The only place where the time is invalid is when the ACPI_CSTATE_FFH entry
method is not set. Otherwise for all the drivers, the time can be correctly
measured.

Instead of duplicating the CPUIDLE_FLAG_TIME_VALID flag in all the drivers
for all the states, just invert the logic by replacing it by the flag
CPUIDLE_FLAG_TIME_INVALID, hence we can set this flag only for the acpi idle
driver, remove the former flag from all the drivers and invert the logic with
this flag in the different governor.

SH: cpuidle: Add missing parameter for cpuidle_register()

2013-08-12T09:28:18+00:00

arch/sh/kernel/cpu/shmobile/cpuidle.c: In function 'sh_mobile_setup_cpuidle':
arch/sh/kernel/cpu/shmobile/cpuidle.c:102:2: error: too few arguments to function 'cpuidle_register'
include/linux/cpuidle.h:129:12: note: declared here
arch/sh/kernel/cpu/shmobile/cpuidle.c:94:6: warning: unused variable 'ret' [-Wunused-variable]

Add the missing parameter, and remove the unused variable.

Both introduced by commit b181a3b03f866776211f22390c185c4da1dc45ff ("SH:

cpuidle: remove en_core_tk_irqen flag

2013-04-23T11:45:22+00:00

The en_core_tk_irqen flag is set in all the cpuidle driver which
means it is not necessary to specify this flag.

Remove the flag and the code related to it.

SH: cpuidle: check error code at init

2013-04-21T22:35:53+00:00

Registering the driver, or the device, can fail, let's check the return code
and return the error code to the PM layer.

SH: cpuidle: initialize the driver's states directly

2013-04-21T22:35:53+00:00

Like all the other drivers, let's initialize the structure a compile time
instead of init time.

The states #1 and #2 are not enabled by default. The init function will
check the features of the board in order to enable the state.

SH: cpuidle: remove CPUIDLE_DRIVER_STATE_START usage

2013-04-21T22:35:52+00:00

The CPUIDLE_DRIVER_STATE_START constant is only set when the kernel compilation
option CONFIG_ARCH_HAS_CPU_RELAX is set, but this is only relatated to x86, so
it is always zero.

Remove the reference to this constant in the code.

The driver is a global static variable automatically initialized to zero.
