2012-03-12fbdev: sh_mobile_meram: Use genalloc to manage MERAM allocationLaurent Pinchart
Instead of requiring the users to hardcode MERAM allocation in platform data, allocate blocks at runtime using genalloc. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12arm: mach-shmobile: Split MERAM resources into regs and meramLaurent Pinchart
The MERAM resource currently combines both the registers space and the MERAM space. Only the register space needs to be ioremapped, split the resource to make that possible. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2012-03-12fbdev: sh_mobile_lcdc: Rename (lcd|num)_cfg (lcd|num)_modesLaurent Pinchart
The struct sh_mobile_lcdc_chan_cfg platform data contains a list of video modes. Name the lcd_cfg and num_cfg fields to reflect that they describe video modes. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2012-03-12ARM: mach-shmobile: default to no earlytimerMagnus Damm
Now when all SoCs and boards are converted to use shmobile_earlytimer_init(), change the default behavior of shmobile_timer.init() from using early timer to do nothing which is suitable for upcoming DT support.

2012-03-13ARM: davinci: DA850: move da850_register_pm to .init.textUwe Kleine-König
All callers (board-mityomapl138.c and board-da850-evm.c) use it in __init functions only. This fixes: WARNING: vmlinux.o(.text+0xd664): Section mismatch in reference from the function da850_register_pm() to the function .init.text:da8xx_get_mem_ctlr() The function da850_register_pm() references the function __init da8xx_get_mem_ctlr(). This is often because da850_register_pm lacks a __init annotation or the annotation of da8xx_get_mem_ctlr is wrong.

2012-03-12sched: Cleanup cpu_active madnessPeter Zijlstra
Stepan found: CPU0 CPUn _cpu_up() __cpu_up() boostrap() notify_cpu_starting() set_cpu_online() while (!cpu_active()) cpu_relax() <PREEMPT-out> smp_call_function(.wait=1) /* we find cpu_online() is true */ arch_send_call_function_ipi_mask() /* wait-forever-more */ <PREEMPT-in> local_irq_enable() cpu_notify(CPU_ONLINE) sched_cpu_active() set_cpu_active() Now the purpose of cpu_active is mostly with bringing down a cpu, where we mark it !active to avoid the load-balancer from moving tasks to it while we tear down the cpu. This is required because we only update the sched_domain tree after we brought the cpu-down. And this is needed so that some tasks can still run while we bring it down, we just don't want new tasks to appear. On cpu-up however the sched_domain tree doesn't yet include the new cpu, so its invisible to the load-balancer, regardless of the active state. So instead of setting the active state after we boot the new cpu (and consequently having to wait for it before enabling interrupts) set the cpu active before we set it online and avoid the whole mess.
