Revert "irqchip/gic-v2: implement suspend and resume"
This reverts commit fc8e11b2564f68a1308b5e5a0f0c801bd788d9f2. With this change present interrupt miss issue was seen even when irq was defined with no suspend flag. While at this do not remove the gic_show_resume_irq() that helps to print the IRQ wake up reason.

irqchip/gic: Atomically update affinity
commit 005c34ae4b44f085120d7f371121ec7ded677761 upstream. The GIC driver uses a RMW sequence to update the affinity, and relies on the gic_lock_irqsave/gic_unlock_irqrestore sequences to update it atomically. But these sequences only expand into anything meaningful if the BL_SWITCHER option is selected, which almost never happens. It also turns out that using a RMW and locks is just as silly, as the GIC distributor supports byte accesses for the GICD_TARGETRn registers, which when used make the update atomic by definition. Drop the terminally broken code and replace it by a byte write.

cpu_pm: Add level to the cluster pm notification
Cluster pm notifications without level information increases difficulty and complexity for the registered drivers to figure out when the last coherency level is going into power collapse. Send notifications with level information that allows the registered drivers to easily determine the cluster level that is going in/out of power collapse. There is an issue with this implementation. GIC driver saves and restores the distributed registers as part of cluster notifications. On newer platforms there are multiple cluster levels are defined (e.g l2, cci etc). These cluster level notifications can happen independently. On MSM platforms GIC is still active while the cluster sleeps in idle, causing the GIC state to be overwritten with an incorrect previous state of the interrupts. This leads to a system hang. Do not save and restore on any L2 and higher cache coherency level sleep entry and exit.

irqchip/gic: Ensure we have an ISB between ack and ->handle_irq
Devices that expose their interrupt status registers via system registers (e.g. Statistical profiling, CPU PMU, DynamIQ PMU, arch timer, vgic (although unused by Linux), ...) rely on a context synchronising operation on the CPU to ensure that the updated status register is visible to the CPU when handling the interrupt. This usually happens as a result of taking the IRQ exception in the first place, but there are two race scenarios where this isn't the case. For example, let's say we have two peripherals (X and Y), where Y uses a system register for its interrupt status. Case 1: 1. CPU takes an IRQ exception as a result of X raising an interrupt 2. Y then raises its interrupt line, but the update to its system register is not yet visible to the CPU 3. The GIC decides to expose Y's interrupt number first in the Ack register 4. The CPU runs the IRQ handler for Y, but the status register is stale Case 2: 1. CPU takes an IRQ exception as a result of X raising an interrupt 2. CPU reads the interrupt number for X from the Ack register and runs its IRQ handler 3. Y raises its interrupt line and the Ack register is updated, but again, the update to its system register is not yet visible to the CPU. 4. Since the GIC drivers poll the Ack register, we read Y's interrupt number and run its handler without a context synchronisation operation, therefore seeing the stale register value. In either case, we run the risk of missing an IRQ. This patch solves the problem by ensuring that we execute an ISB in the GIC drivers prior to invoking the interrupt handler. This is already the case for GICv3 and EOIMode 1 (the usual case for the host).

irqchip/gic: Make locking a BL_SWITCHER only feature
The BL switcher code manipulates the logical/physical CPU mapping, forcing a lock to be taken on the IPI path. With an IPI heavy load, this single lock becomes contended. But when CONFIG_BL_SWITCHER is not enabled, there is no reason to take this lock at all since the CPU mapping is immutable. This patch allows the lock to be entierely removed when BL_SWITCHER is not enabled (which is the case in most configurations), leading to a small improvement of "perf bench sched pipe" (measured on an 8 core AMD Seattle system): Before: 101370 ops/sec After: 103680 ops/sec Take this opportunity to remove a useless lock being taken when handling an interrupt on a secondary GIC.

irqchip/gic: Add platform driver for non-root GICs that require RPM
Add a platform driver to support non-root GICs that require runtime power-management. Currently, only non-root GICs are supported because the functions, smp_cross_call() and set_handle_irq(), that need to be called for a root controller are located in the __init section and so cannot be called by the platform driver. The GIC platform driver re-uses many functions from the existing GIC driver including some functions to save and restore the GIC context during power transitions. The functions for saving and restoring the GIC context are currently only defined if CONFIG_CPU_PM is enabled and to ensure that these functions are always defined when the platform driver is enabled, a dependency on CONFIG_ARM_GIC_PM (which selects the platform driver) has been added. In order to re-use the private GIC initialisation code, a new public function, gic_of_init_child(), has been added which calls various private functions to initialise the GIC. This is different from the existing gic_of_init() because it only supports non-root GICs (ie. does not call smp_cross_call() is set_handle_irq()) and is not located in the __init section (so can be used by platform drivers). Furthermore, gic_of_init_child() dynamically allocates memory for the GIC chip data which is also different from gic_of_init(). There is no specific suspend handling for GICs registered as platform devices. Non-wakeup interrupts will be disabled by the kernel during late suspend, however, this alone will not power down the GIC if interrupts have been requested and not freed. Therefore, requestors of non-wakeup interrupts will need to free them on entering suspend in order to power-down the GIC.

To prepare for adding a platform driver: 1. Drop the __init section from the gic_dist_config() so this can be re-used by the platform driver. 2.

In preparation for supporting such GICs, move the code that initialises the irqchip structure for a GIC into its own function called gic_init_chip() where the parent device pointer is also set. Instead of calling gic_init_chip() from within gic_init_bases(), move the calls to outside of this function, so that in the future we can avoid having to pass additional parameters to gic_init_bases() in order set the parent device pointer or set the name to a specific string.

irqchip/gic: Isolate early GIC initialisation code
To re-use the code that initialises the GIC (found in __gic_init_bases()), from within a platform driver, it is necessary to move the code from the __init section so that it is always present and not removed. Unfortunately, it is not possible to simply drop the __init from the function declaration for __gic_init_bases() because it contains calls to set_smp_cross_call() and set_handle_irq() which are both located in the __init section. Fortunately, these calls are only required for the root controller and because the initial platform driver will only support non-root controllers that can be initialised later in the boot process, we can move these calls to another function. Move the bulk of the code from __gic_init_bases() to a new function called gic_init_bases() which is not located in the __init section and can be used by the platform driver. Update __gic_init_bases() to call gic_init_bases() and if necessary, set_smp_cross_call() and set_handle_irq().

remove lots of IS_ERR_VALUE abuses
Most users of IS_ERR_VALUE() in the kernel are wrong, as they pass an 'int' into a function that takes an 'unsigned long' argument. This happens to work because the type is sign-extended on 64-bit architectures before it gets converted into an unsigned type. However, anything that passes an 'unsigned short' or 'unsigned int' argument into IS_ERR_VALUE() is guaranteed to be broken, as are 8-bit integers and types that are wider than 'unsigned long'. Andrzej Hajda has already fixed a lot of the worst abusers that were causing actual bugs, but it would be nice to prevent any users that are not passing 'unsigned long' arguments. This patch changes all users of IS_ERR_VALUE() that I could find on 32-bit ARM randconfig builds and x86 allmodconfig. For the moment, this doesn't change the definition of IS_ERR_VALUE() because there are probably still architecture specific users elsewhere. Almost all the warnings I got are for files that are better off using 'if (err)' or 'if (err < 0)'. The only legitimate user I could find that we get a warning for is the (32-bit only) freescale fman driver, so I did not remove the IS_ERR_VALUE() there but changed the type to 'unsigned long'. For 9pfs, I just worked around one user whose calling conventions are so obscure that I did not dare change the behavior. I was using this definition for testing: #define IS_ERR_VALUE(x) ((unsigned long*)NULL == (typeof (x)*)NULL && \ unlikely((unsigned long long)(x) >= (unsigned long long)(typeof(x))-MAX_ERRNO)) which ends up making all 16-bit or wider types work correctly with the most plausible interpretation of what IS_ERR_VALUE() was supposed to return according to its users, but also causes a compile-time warning for any users that do not pass an 'unsigned long' argument. I suggested this approach earlier this year, but back then we ended up deciding to just fix the users that are obviously broken. After the initial warning that caused me to get involved in the discussion (fs/gfs2/dir.c) showed up again in the mainline kernel, Linus asked me to send the whole thing again.

irqchip/gic: Return an error if GIC initialisation fails
If the GIC initialisation fails, then currently we do not return an error or clean-up afterwards. Although for root controllers, this failure may be fatal anyway, for secondary controllers, it may not be fatal and so return an error on failure and clean-up. Update the functions gic_cpu_init() and gic_pm_init() to return an error instead of calling BUG() and perform any necessary clean-up. For non-banked GIC controllers, make sure that we free any memory allocated if we fail to initialise the IRQ domain. Please note that free_percpu() only frees memory if the pointer passed to it is not NULL and so it is unnecessary to check if both pointers are valid or not.

irqchip/gic: Ensure ordering between read of INTACK and shared data
When an IPI is generated by a CPU, the pattern looks roughly like: <write shared data> smp_wmb(); <write to GIC to signal SGI> On the receiving CPU we rely on the fact that, once we've taken the interrupt, then the freshly written shared data must be visible to us. Put another way, the CPU isn't going to speculate taking an interrupt. Unfortunately, this assumption turns out to be broken. Consider that CPUx wants to send an IPI to CPUy, which will cause CPUy to read some shared_data. Before CPUx has done anything, a random peripheral raises an IRQ to the GIC and the IRQ line on CPUy is raised. CPUy then takes the IRQ and starts executing the entry code, heading towards gic_handle_irq. Furthermore, let's assume that a bunch of the previous interrupts handled by CPUy were SGIs, so the branch predictor kicks in and speculates that irqnr will be <16 and we're likely to head into handle_IPI. The prefetcher then grabs a speculative copy of shared_data which contains a stale value. Meanwhile, CPUx gets round to updating shared_data and asking the GIC to send an SGI to CPUy. Internally, the GIC decides that the SGI is more important than the peripheral interrupt (which hasn't yet been ACKed) but doesn't need to do anything to CPUy, because the IRQ line is already raised. CPUy then reads the ACK register on the GIC, sees the SGI value which confirms the branch prediction and we end up with a stale shared_data value. This patch fixes the problem by adding an smp_rmb() to the IPI entry code in gic_handle_irq. As it turns out, the combination of a control dependency and an ISB instruction from the EOI in the GICv3 driver is enough to provide the ordering we need, so we add a comment there justifying the absence of an explicit smp_rmb().

irqchip/gic: Only set the EOImodeNS bit for the root controller
EOImode1 is only used for the root controller and hence only the root controller uses the eoimode1 functions for handling interrupts. However, if the root controller supports EOImode1, then the EOImodeNS bit will be set for all GICs, enabling EOImode1. This is not what we want and this causes interrupts on non-root GICs to only be dropped in priority but never deactivated. Therefore, only set the EOImodeNS bit for the root controller.

irqchip/gic: Kconfig the number of instances
There is currently a hack in the GIC driver making it possible to pass the number of GIC instances from the platform-specific include files and thus override the variable MAX_GIC_NR. With multiplatform deployments, this will not work as we need to get rid of the platform-specific include files. It turns out that this feature is only used by the RealView platform which has a cascaded GIC. So move the configuration to Kconfig and bump to 2 instances if we're building for the RealView. The include file hacks can then be removed. Tested on the ARM PB11MPCore with its cascaded GIC.

irqchip/gic: Support RealView variant setup
The ARM RealView PB11MPCore reference design has some special bits in a system controller register to set up the GIC in one of three modes: legacy, new with DCC, new without DCC. The register is also used to enable FIQ. Since the platform will not boot unless this register is set up to "new with DCC" mode, we need a special quirk to be compiled-in for the RealView platforms. If we find the right compatible string on the GIC TestChip, we enable this quirk by looking up the system controller and enabling the special bits. We depend on the CONFIG_REALVIEW_DT Kconfig symbol as the old boardfile code has the same fix hardcoded, and this is only needed for the attempts to modernize the RealView code using device tree. After fixing this, the PB11MPCore boots with device tree only.

irqchip/gic: Add save/restore of the active state
When using EOImode==1, we may mark interrupts as being forwarded to a virtual machine. In that case, the interrupt is left active while being passed to the VM. If we suspend the system before the VM has deactivated the interrupt, the active state will be lost (which may be very annoying, as this may result in spurious interrupts and a confused guest).

irqchip/gic: Clear enable bits before restoring them
When restoring the GIC state (after a suspend/resume cycle, for example), the driver directly writes the 'enabled' state it has saved by accessing GICD_ISENABLERn, which performs an OR operation between the value present in the register and the value we write. If whatever code that has run before we reentered the kernel has enabled an interrupt that was previously disabled, we won't restore that disabled state.
