git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing Jonathan writes: First round of IIO new drivers, cleanups and functionality for the 3.20 cycle take 2 Updated pull request with Daniel's fix on top for the power management Kconfig changes that had snuck in since last update of the IIO tree worked it's way through from mainline. Original pull message New device support * jsa1212 proxmity / ambient light sensor * SM08500 supported added to the kxcjk-1013 accelerometer driver * KMX61 Accelerometer/Magnetometer. This took a somewhat rocky path being first merged, then reverted for a rewrite after a discussion of how to support additional functionality and finally being merged prior to some last reviews coming in, with resultant follow up patches. * Freescale mma9551l driver (minor follow up warning supression patch). * Semtech SX9500 proximity device driver. * ak8975 gains support for ak09911 and ak09912 and drop the standalone driver for the ak09911. New functionality * Dummy driver gains some virtual registers making it more flexible. * IIO_ACTIVITY channel types, with modifiers running, walking etc. This is to support on chip motion clasifiers. As such it is in the form of a confidence percentage. The only devices so far only do binary decisions but this gives us room when other devices give more nuanced clasification. * IIO_EV_DIR_NONE type for events where there is no obvious direction. First case is step detection. * IIO_STEPS channel type for pedometers. * ENABLE mask element used to control turning on counting types such as the pedometer that need a 'start point'. * INSTANCE event type to support things that happen once. * info element for height calibration (used in various motion estimation algorithms). Note heigh tof use * dummy driver demonstration of the use of all the new bits above. * event monitor support for the new events. * inv_mpu6050 gains an i2c mux to allow bypassing the device to access additional devices connected on the other side of it. Note that in Windows these are handled by firmware on the device and not exposed directly. * inv_mpu6050 gains ACPI enumeration. * inkern interface gains iio_write_channel_raw to allow in kernel users of DAC functionality via a simple wrapper. * Document input current readings in the ABI docs. * Add an error message when we get an out of range error in device tree processing for the in kernel interfaces. Basically a device tree debugging aid. * Add a sanity check that a scan index for a channel is unique during registration. There to help catch bugs as this should never happen in a bug free driver. Cleanups and fixlets A rework of buffer registration from Lars - a precursor to some other upcoming new stuff (a few patches from others rolled in here as well). * Ensure all drivers register the same channels for the device and buffer. * Move buffer registration into the core rather than using the old two step approach. Now we have simple ways of using a unified set channels for both without requiring channels be exposed by both interface, this removes a fair bit of boilerplate. * Stop sca3000 and ad5933 (both in staging) enabling buffer channels by default. It has long be convention in IIO to startup with no channels enabled and leave it up to userspace to say what goes in the buffer. Getting rid of these allows us to drop export of iio_scan_mask_set. * Drop get_bytes_per_datum from iio_buffer_access_funcs as not been used for a while. * Allocate standard buffer attributes in the core rather than in every driver with a buffer. * Make the length attribute read only when a driver is not able to set the length. * Drop the get_length callback for buffers as it is already available in struct iio_buffer. * Drop an unused arguement form iio_kfifo_allocate and add devm allocator for it. * some kconfig entries gain anotation with the resulting module name. * Fix a resulting compile issue in dummy driver due to a stub taking wrong parameters as a result of the above rework. * Fix an off by 2 error in copying the core assigned buffer attributes. Other cleanups, * Trivial space before comma fixups. * ak8975 fixlets - none critical. Rework to allow more device support. * Drop unnecessary sizeof(u8) calls. * bmp280 - refactor the compensation code to reduce copy operations and code length. A second patch futher optimized this and performed some other minor cleanups. * kxcjk-1013 - various power control cleanups to avoid unnecessary enable / disable of device. Make sure it is only controlled at all if CONFIG_PM is enabled. Also som cleanups of error paths. * Small cleanups in adf4530 driver - pointless message and unnecessary braces. * Clarifiy the proximity ABI docs to make it clear it should get bigger as we move futher away. * Drop a misleading comment form industrialio-core.c * Trivial white space cleanups. * sca3000 looses an unused debug function. * Fix char unsigned ordering in ad8366 * Increase the sleep time in ad9523 to make it predictable (value didn't really matter so make it more than 20 msecs) * mxs-lradc touchscreen property cleanups in device tree are fixed to ensure the meet all the 'interesting' documentation. * A couple of cleanups for the staging ad5933 driver to avoid unnecessary conversion to a processed temperature vlaue in kernel and remove platform data form the state structure as not needed after probe. * Fix a wrong scale factor in the docs. Misc * Add IIO include files to the maintainers entry.

2015-01-20fs: introduce f_op->mmap_capabilities for nommu mmap supportChristoph Hellwig
Since "BDI: Provide backing device capability information [try #3]" the backing_dev_info structure also provides flags for the kind of mmap operation available in a nommu environment, which is entirely unrelated to it's original purpose. Introduce a new nommu-only file operation to provide this information to the nommu mmap code instead. Splitting this from the backing_dev_info structure allows to remove lots of backing_dev_info instance that aren't otherwise needed, and entirely gets rid of the concept of providing a backing_dev_info for a character device.

2015-01-20livepatch: support for repatching a functionJosh Poimboeuf
Add support for patching a function multiple times. If multiple patches affect a function, the function in the most recently enabled patch "wins". This enables a cumulative patch upgrade path, where each patch is a superset of previous patches. This requires restructuring the data a little bit. With the current design, where each klp_func struct has its own ftrace_ops, we'd have to unregister the old ops and then register the new ops, because FTRACE_OPS_FL_IPMODIFY prevents us from having two ops registered for the same function at the same time. That would leave a regression window where the function isn't patched at all (not good for a patch upgrade path). This patch replaces the per-klp_func ftrace_ops with a global klp_ops list, with one ftrace_ops per original function. A single ftrace_ops is shared between all klp_funcs which have the same old_addr. This allows the switch between function versions to happen instantaneously by updating the klp_ops struct's func_stack list. The winner is the klp_func at the top of the func_stack (front of the list).

2015-01-20arm/arm64: KVM: allow userland to request a virtual GICv3Andre Przywara
With all of the GICv3 code in place now we allow userland to ask the kernel for using a virtual GICv3 in the guest. Also we provide the necessary support for guests setting the memory addresses for the virtual distributor and redistributors. This requires some userland code to make use of that feature and explicitly ask for a virtual GICv3. Document that KVM_CREATE_IRQCHIP only works for GICv2, but is considered legacy and using KVM_CREATE_DEVICE is preferred.

2015-01-20arm/arm64: KVM: enable kernel side of GICv3 emulationAndre Przywara
With all the necessary GICv3 emulation code in place, we can now connect the code to the GICv3 backend in the kernel. The LR register handling is different depending on the emulated GIC model, so provide different implementations for each. Also allow non-v2-compatible GICv3 implementations (which don't provide MMIO regions for the virtual CPU interface in the DT), but restrict those hosts to support GICv3 guests only. If the device tree provides a GICv2 compatible GICV resource entry, but that one is faulty, just disable the GICv2 emulation and let the user use at least the GICv3 emulation for guests. To provide proper support for the legacy KVM_CREATE_IRQCHIP ioctl, note virtual GICv2 compatibility in struct vgic_params and use it on creating a VGICv2.

2015-01-20arm64: KVM: add SGI generation register emulationAndre Przywara
While the generation of a (virtual) inter-processor interrupt (SGI) on a GICv2 works by writing to a MMIO register, GICv3 uses the system register ICC_SGI1R_EL1 to trigger them. Add a trap handler function that calls the new SGI register handler in the GICv3 code. As ICC_SRE_EL1.SRE at this point is still always 0, this will not trap yet, but will only be used later when all the data structures have been initialized properly.

2015-01-20arm/arm64: KVM: add virtual GICv3 distributor emulationAndre Przywara
With everything separated and prepared, we implement a model of a GICv3 distributor and redistributors by using the existing framework to provide handler functions for each register group. Currently we limit the emulation to a model enforcing a single security state, with SRE==1 (forcing system register access) and ARE==1 (allowing more than 8 VCPUs). We share some of the functions provided for GICv2 emulation, but take the different ways of addressing (v)CPUs into account. Save and restore is currently not implemented. Similar to the split-off of the GICv2 specific code, the new emulation code goes into a new file (vgic-v3-emul.c).

ICC_SRE_EL1 is a system register allowing msr/mrs accesses to the GIC CPU interface for EL1 (guests). Currently we force it to 0, but for proper GICv3 support we have to allow guests to use it (depending on their selected virtual GIC model). So add ICC_SRE_EL1 to the list of saved/restored registers on a world switch, but actually disallow a guest to change it by only restoring a fixed, once-initialized value. This value depends on the GIC model userland has chosen for a guest.

Currently we only have one virtual GIC model supported, so all guests use the same emulation code.

Introduce a vgic_vm_ops struct to hold function pointers for those functions that are different and provide the necessary code to initialize them. Also split up the vgic_init() function to separate out VGIC model specific functionality into a separate function, which will later be different for a GICv3 model.

Because of this style, include/linux/mfd/tmio.h header has tmio driver/framework specific data which is not needed from platform. This patch adds new tmio_mmc_host_alloc/free() as cleanup preparation. tmio driver specific data/callback will be implemented in tmio_mmc_host, and platform specific data/callback will be implemented in tmio_mmc_data in this cleanup.

As documented in Documentation/kernel-doc-nano-HOWTO.txt lines terminated with a colon are treated as headings. The current layout of the documentation when compiling the kernel crypto API DocBook documentation is messed up by by treating some lines as headings. The patch removes colons from comments that shall not be treated as headings. Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-01-20module: remove mod arg from module_free, rename module_memfree().Rusty Russell
Nothing needs the module pointer any more, and the next patch will call it from RCU, where the module itself might no longer exist. Removing the arg is the safest approach. This just codifies the use of the module_alloc/module_free pattern which ftrace and bpf use.

2015-01-20module_arch_freeing_init(): new hook for archs before module->module_init freed.Rusty Russell
Archs have been abusing module_free() to clean up their arch-specific allocations. Since module_free() is also (ab)used by BPF and trace code, let's keep it to simple allocations, and provide a hook called before that. This means that avr32, ia64, parisc and s390 no longer need to implement their own module_free() at all. avr32 doesn't need module_finalize() either.
