* ARM: cpu hotplug: remove majority of cache flushing from platformsRussell King2013-04-181-4/+0
| | | | | | | Remove the majority of cache flushing calls from the individual platform files. This is now handled by the core code. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* ARM: msm: Move core.h contents into common.hDavid Brown2012-09-221-1/+1
| | | | | | | | | No real need to have a separate core.h from the common.h file. Fold these two prototypes into the common header file. Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David Brown <davidb@codeaurora.org> Signed-off-by: Olof Johansson <olof@lixom.net>
* ARM: consolidate pen_release instead of having per platform definitionsMarc Zyngier2012-09-141-2/+0
| | | | | | | | | | | | | | Almost each SMP platform defines pen_release to manage booting secondary CPUs. This of course clashes with the single zImage effort. Add the pen_release definition to the ARM SMP code, and remove all others. This should only be used by platforms which lack any kind of CPU power management...

* ARM: SoC: convert MSM to SMP operationsMarc Zyngier2012-09-141-15/+3
| | | | | | | | | | Convert MSM SMP platforms to use struct smp_operations to provide their SMP and CPU hotplug operations.

* ARM: 7293/1: logical_cpu_map: decouple CPU mapping from SMPWill Deacon2012-01-231-0/+1
| | | | | | | | | | | | | | | | | It turns out that the logical CPU mapping is useful even when !CONFIG_SMP for manipulation of devices like interrupt and power controllers when running a UP kernel on a CPU other than 0. This can happen when kexecing a UP image from an SMP kernel. In the future, multi-cluster systems running AMP configurations will require something similar for mapping cluster IDs, so it makes sense to decouple this logic in preparation for this support.

* ARM: msm: convert logical CPU numbers to physical numbersWill Deacon2011-10-171-1/+1
| | | | | | | | | This patch uses the new cpu_logical_map() macro for converting logical CPU numbers into physical numbers when dealing with the pen_release variable in the SMP boot and CPU hotplug paths.
