2014-11-02irqchip: armada-370-xp: Fix MPIC interrupt handlingGrzegorz Jaszczyk1-6/+17
In both Armada-375 and Armada-38x MPIC interrupts should be identified by reading cause register multiplied by the interrupt mask. A lack of above mentioned multiplication resulted in a bug, caused by the fact that in Armada-375 and Armada-38x some of the interrupts (e.g. network interrupts) can be handled either as a GIC or MPIC interrupts. Therefore during MPIC interrupts handling, cause register shows hits from interrupts even if they are masked for MPIC but unmasked for a GIC. This resulted in 'bad IRQ' error, because masked MPIC interrupt without registered interrupt handler, was trying to be handled during interrupt handling procedure of some other unmasked MPIC interrupt (e.g. local timer irq). This commit fixes that by ensuring that during MPIC interrupt handling only interrupts that are unmasked for MPIC are processed.

2014-11-02irqchip: armada-370-xp: Fix MSI interrupt handlingGrzegorz Jaszczyk1-2/+2
The MSI interrupts use the 16 high doorbells, which are notified by using IRQ1 of the main interrupt controller. The MSI interrupts were handled correctly for Armada-XP and Armada-370 but not for Armada-375 and Armada-38x, which use chained handler for the MPIC. This commit fixes that by checking proper interrupt number in chained handler for the MPIC.

Pull percpu consistent-ops changes from Tejun Heo: "Way back, before the current percpu allocator was implemented, static and dynamic percpu memory areas were allocated and handled separately and had their own accessors. The distinction has been gone for many years now; however, the now duplicate two sets of accessors remained with the pointer based ones - this_cpu_*() - evolving various other operations over time. During the process, we also accumulated other inconsistent operations. This pull request contains Christoph's patches to clean up the duplicate accessor situation. __get_cpu_var() uses are replaced with with this_cpu_ptr() and __this_cpu_ptr() with raw_cpu_ptr(). Unfortunately, the former sometimes is tricky thanks to C being a bit messy with the distinction between lvalues and pointers, which led to a rather ugly solution for cpumask_var_t involving the introduction of this_cpu_cpumask_var_ptr(). This converts most of the uses but not all. Christoph will follow up with the remaining conversions in this merge window and hopefully remove the obsolete accessors" * 'for-3.18-consistent-ops' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: (38 commits) irqchip: Properly fetch the per cpu offset percpu: Resolve ambiguities in __get_cpu_var/cpumask_var_t -fix ia64: sn_nodepda cannot be assigned to after this_cpu conversion.

2014-09-14irqchip: gic-v3: Implement CPU PM notifierSudeep Holla1-11/+46
When a CPU enters a low power state, the contents of the GICv3/4 system registers are lost. They need to be saved and restored if required. For now, since most of the GICv3 register are set some initial values and not modified at runtime, it is better to re-initialise rather than saving and restoring them. It may need to be saved and restored in future if required. This patch adds a notifier to disable the redistributor(if allowed) and Group1 interrupts when powering down the processor and to re-initialise the system registers on wakeup.

Currently gic_enable_redist configures the redistributors to never assert WakeRequest signal. However when powering down the processors with wake-up enabled(i.e suspend), we need to configure it to assert that signal.

This is just enough to let pm_clk_*() enable the functional clock, and manage it for suspend/resume, if present. Before, it was assumed enabled by the bootloader or reset state. To prevent the clock from being disabled while the module is needed for wake-up, implement irq_chip.irq_set_wake(), which increments/decrements the clock's enable_count when needed.

2014-09-03irqchip: gic-v3: Declare rdist as __percpu pointer to __iomem pointerWill Deacon1-1/+1
The __percpu __iomem annotations on the rdist base are contradictory and confuse static checkers such as sparse. This patch fixes the anotations so that rdist is described as a __percpu pointer to an __iomem pointer.
