2013-01-12irqchip: Move ARM gic.h to include/linux/irqchip/arm-gic.hRob Herring
Now that we have GIC moved to drivers/irqchip and all GIC DT init for platforms using irqchip_init, move gic.h and update the remaining includes.

2013-01-10ARM: GIC: remove direct use of gic_raise_softirqRob Herring
In preparation of moving gic code to drivers/irqchip, remove the direct platform dependencies on gic_raise_softirq. Move the setup of smp_cross_call into the gic code and use arch_send_wakeup_ipi_mask function to trigger wake-up IPIs.

2012-11-13Revert "ARM: shmobile: emev2: Replace modify_scu_cpu_psr with scu_power_mode"Simon Horman
This reverts commit 865d90f80384d62e6fbe835159cb674dec32ccb5. The code changes the flags of the wrong cpus - which breaks the whole bootup of secondary CPUs. Cc: Bastian Hecht <hechtb@gmail.com> Signed-off-by: Simon Horman <horms@verge.net.au>
2012-11-06ARM: shmobile: emev2: Replace modify_scu_cpu_psr with scu_power_modeBastian Hecht
We can remove the extra code of modify_scu_cpu_psr() and use the cleaner generic ARM helper scu_power_mode(). As every CPU only deals with its own power register and scu_power_mode() operates with 8-bit accesses, we save the locking overhead too.

2012-10-07Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds
Pull ARM updates from Russell King: "This is the first chunk of ARM updates for this merge window. Conflicts are expected in two files - asm/timex.h and mach-integrator/integrator_cp.c. Nothing particularly stands out more than anything else. Most of the growth is down to the opcodes stuff from Dave Martin, which is countered by Rob's patches to use more of the asm-generic headers on ARM."

2012-05-18mach-shmobile: Emma Mobile EV2 SMP support V3Magnus Damm
This is V3 of Emma Mobile EV2 SMP support. At this point only the most basic form of SMP operation is supported. TWD and CPU Hotplug support is excluded. Tied to both the Emma Mobile EV2 and the KZM9D board due to the need to switch on board in platsmp.c and the newly introduced need for static mappings. The static mappings are needed to allow hardware acces early during boot when SMP is initialized. This early requirement forces us to also map in the SMU registers.
