2015-06-16drivers/cpuidle: Convert non-modular drivers to use builtin_platform_driverPaul Gortmaker
All these drivers are configured with Kconfig options that are declared as bool. Hence it is not possible for the code to be built as modular. However the code is currently using the module_platform_driver() macro for driver registration. While this currently works, we really don't want to be including the module.h header in non-modular code, which we'll be forced to do, pending some upcoming code relocation from init.h into module.h. So we fix it now by using the non-modular equivalent. Cc: "Rafael J.

2015-03-23ARM: cpuidle: Remove duplicate header inclusionDaniel Lezcano
The cpu_do_idle() function is always used by the cpuidle drivers. That led to have each driver including cpuidle.h and proc-fns.h, they are always paired. That makes a lot of duplicate headers inclusion. Instead of including both in each .c file, move the proc-fns.h header inclusion in the cpuidle.h header file directly, so we can save some line of code.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core update from Greg KH: "Here's the set of driver core patches for 3.19-rc1. They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

2014-11-12cpuidle: Invert CPUIDLE_FLAG_TIME_VALID logicDaniel Lezcano
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.
