2012-06-14ARM: LPC32xx: Remove mach specific ARCH_NR_GPIOS, use defaultRoland Stigge

2012-06-14ARM: LPC32xx: Adjust dtsi file for MLC controller configurationRoland Stigge
This patch takes into account that the MTD NAND MLC controller needs more registers, located actually before the previously allocated memory range, already starting at 200a8000 instead of 200b0000.

2012-06-14ARM: LPC32xx: Remove SLC controller initialization from platform initRoland Stigge
Since we now support two MTD NAND controllers (MLC and SLC) for LPC32xx via DT, we don't initialize the SLC controller statically anymore, but do it via the clock setup (see previous patch). Signed-off-by: Roland Stigge <stigge@antcom.de> Tested-by: Alexandre Pereira da Silva <aletes.xgr@gmail.com>

2012-06-04ARM: dma-mapping: remove unconditional dependency on CMAMarek Szyprowski
CMA has been enabled unconditionally on all ARMv6+ systems to solve the long standing issue of double kernel mappings for all dma coherent buffers. This however created a dependency on CONFIG_EXPERIMENTAL for the whole ARM architecture what should be really avoided. This patch removes this dependency and lets one use old, well-tested dma-mapping implementation also on ARMv6+ systems without the need to use EXPERIMENTAL stuff.

While we originally to get a much larger set of ux500 device tree enablement patches merged, this did not happen in time. After some discussion at Linaro Connect conference this week, Lee has been able to do damage control and provide a series to put the broken platform back into usable shape for both DT and non-DT based booting.

2012-06-01new helper: signal_delivered()Al Viro
Does block_sigmask() + tracehook_signal_handler(); called when sigframe has been successfully built. All architectures converted to it; block_sigmask() itself is gone now (merged into this one). I'm still not too happy with the signature, but that's a separate story (IMO we need a structure that would contain signal number + siginfo + k_sigaction, so that get_signal_to_deliver() would fill one, signal_delivered(), handle_signal() and probably setup...frame() - take one).

2012-05-31arm: use clear_tasks_mm_cpumask()Anton Vorontsov
Checking for process->mm is not enough because process' main thread may exit or detach its mm via use_mm(), but other threads may still have a valid mm. To fix this we would need to use find_lock_task_mm(), which would walk up all threads and returns an appropriate task (with task lock held). clear_tasks_mm_cpumask() has this issue fixed, so let's use it.
