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.

| | | | | | | | | | | | | | | | | | | | | | | | | | [ARM specific] These are generally replaced with raw_cpu_ptr. However, in gic_get_percpu_base() we immediately dereference the pointer.

* | | irqchip: gic: Fix core ID calculation when topology is read from DTTomasz Figa2014-07-181-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain GIC implementation, namely those found on earlier, single cluster, Exynos SoCs, have registers mapped without per-CPU banking, which means that the driver needs to use different offset for each CPU. Currently the driver calculates the offset by multiplying value returned by cpu_logical_map() by CPU offset parsed from DT. This is correct when CPU topology is not specified in DT and aforementioned function returns core ID alone. However when DT contains CPU topology, the function changes to return cluster ID as well, which is non-zero on mentioned SoCs and so breaks the calculation in GIC driver. This patch fixes this by masking out cluster ID in CPU offset calculation so that only core ID is considered. Multi-cluster Exynos SoCs already have banked GIC implementations, so this simple fix should be enough.

The peripheral interrupts are associated with a fixed crossbar input line and the crossbar routes that to one of the free gic input line. The DT entries for peripherals provides the fixed crossbar input line as its interrupt number and the mapping code should associate this with a free gic input line. This patch adds the support inside the gic irqchip to handle such routable irqs. The routable irqs are registered in a linear domain. The registered routable domain's callback should be implemented to get a free irq and to configure the IP to route it.

| * | irqchip: gic: use dmb ishst instead of dsb when raising a softirqWill Deacon2014-02-251-2/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When sending an SGI to another CPU, we require a barrier to ensure that any pending stores to normal memory are made visible to the recipient before the interrupt arrives. Rather than use a vanilla dsb() (which will soon cause an assembly error on arm64) before the writel_relaxed, we can instead use dsb(ishst), since we just need to ensure that any pending normal writes are visible within the inner-shareable domain before we poke the GIC. With this observation, we can then further weaken the barrier to a dmb(ishst), since other CPUs in the inner-shareable domain must observe the write to the distributor before the SGI is generated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is required by the big.LITTLE switcher code. The gic_migrate_target() changes the CPU interface mapping for the current CPU to redirect SGIs to the specified interface, and it also updates the target CPU for each interrupts to that CPU interface if they were targeting the current interface. Finally, pending SGIs for the current CPU are forwarded to the new interface. Because Linux does not use it, the SGI source information for the forwarded SGIs is not preserved. Neither is the source information for the SGIs sent by the current CPU to other CPUs adjusted to match the new CPU interface mapping. The required registers are banked so only the target CPU could do it. Signed-off-by: Nicolas Pitre <nico@linaro.org>
* | drivers: irq-chip: irq-gic: introduce gic_cpu_if_down()Nicolas Pitre2013-08-281-0/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | When processors are about to hit low power states, the assertion of standbywfi signal, triggered by the wfi instruction, is essential to entering low power modes. If an IRQ is pending on the processor at the time wfi is issued, the wfi instruction completes and the processor restarts execution without asserting the standbywfi signal. Depending on the platform power controller HW this behaviour can be acceptable or not; if this behaviour must be prevented software should be provided with a way to disable the routing of interrupts to the core IRQ pins. On systems where raw GIC distributor interrupts are connected to the power controller as wake-up events (hence the power controller still senses IRQs and can wake up cores upon IRQ pending), the GIC CPU interface can be disabled on power down, so that the GIC CPU IF output is gated and wfi cannot complete, thereby preventing the standbywfi issue. This patch adds a simple function to the GIC driver that allows to disable the GIC CPU IF from power down procedures.

* clocksource+irqchip: delete __cpuinit usage from all related filesPaul Gortmaker2013-07-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. This removes all the drivers/clocksource and drivers/irqchip uses of the __cpuinit macros from all C files.

* irqchip: gic: call gic_cpu_init() as well in CPU_STARTING_FROZEN caseShawn Guo2013-06-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit c011470 (irqchip: gic: Perform the gic_secondary_init() call via CPU notifier) moves gic_secondary_init() that used to be called in .smp_secondary_init hook into a notifier call. But it changes the system behavior a little bit. Before the commit, gic_cpu_init() is called not only when kernel brings up the secondary cores but also when system resuming procedure hot-plugs the cores back to kernel. While after the commit, the function will not be called in the latter case, where the 'action' will not be CPU_STARTING but CPU_STARTING_FROZEN. This behavior difference at least causes the following suspend/resume regression on imx6q. $ echo mem > /sys/power/state PM: Syncing filesystems ... done.

This is dominated largely by the Samsung platforms (s3c, s5p, exynos) and a few of the others moving code out of arch/arm into more appropriate subsystems. The clocksource and irqchip drivers are now abstracted to the point where platforms that are already cleaned up do not need to even specify the driver they use, it can all get configured from the device tree as we do for normal device drivers. The clocksource changes basically touch every single platform in the process. We further clean up the use of platform specific header files here, with the goal of turning more of the platforms over to being "multiplatform" enabled, which implies that they cannot expose their headers to architecture independent code any more. It is expected that no functional changes are part of the cleanup.
