2016-10-11Input: i8042 - skip selftest on ASUS laptopsMarcos Paulo de Souza
On suspend/resume cycle, selftest is executed to reset i8042 controller. But when this is done in Asus devices, subsequent calls to detect/init functions to elantech driver fails. Skipping selftest fixes this problem. An easier step to reproduce this problem is adding i8042.reset=1 as a kernel parameter. On Asus laptops, it'll make the system to start with the touchpad already stuck, since psmouse_probe forcibly calls the selftest function. This patch was inspired by John Hiesey's change[1], but, since this problem affects a lot of models of Asus, let's avoid running selftests on them.

2016-10-11kthread: kthread worker API cleanupPetr Mladek
A good practice is to prefix the names of functions by the name of the subsystem. The kthread worker API is a mix of classic kthreads and workqueues. Each worker has a dedicated kthread. It runs a generic function that process queued works. It is implemented as part of the kthread subsystem. This patch renames the existing kthread worker API to use the corresponding name from the workqueues API prefixed by kthread_: __init_kthread_worker() -> __kthread_init_worker() init_kthread_worker() -> kthread_init_worker() init_kthread_work() -> kthread_init_work() insert_kthread_work() -> kthread_insert_work() queue_kthread_work() -> kthread_queue_work() flush_kthread_work() -> kthread_flush_work() flush_kthread_worker() -> kthread_flush_worker() Note that the names of DEFINE_KTHREAD_WORK*() macros stay as they are. It is common that the "DEFINE_" prefix has precedence over the subsystem names. Note that INIT() macros and init() functions use different naming scheme. There is no good solution. There are several reasons for this solution: + "init" in the function names stands for the verb "initialize" aka "initialize worker". While "INIT" in the macro names stands for the noun "INITIALIZER" aka "worker initializer". + INIT() macros are used only in DEFINE() macros + init() functions are used close to the other kthread() functions. It looks much better if all the functions use the same scheme. + There will be also kthread_destroy_worker() that will be used close to kthread_cancel_work(). It is related to the init() function. Again it looks better if all functions use the same naming scheme. + there are several precedents for such init() function names, e.g. amd_iommu_init_device(), free_area_init_node(), jump_label_init_type(), regmap_init_mmio_clk(), + It is not an argument but it was inconsistent even before.

2016-10-11random: simplify API for random address requestsJason Cooper
To date, all callers of randomize_range() have set the length to 0, and check for a zero return value. For the current callers, the only way to get zero returned is if end <= start. Since they are all adding a constant to the start address, this is unnecessary. We can remove a bunch of needless checks by simplifying the API to do just what everyone wants, return an address between [start, start + range). While we're here, s/get_random_int/get_random_long/. No current call site is adversely affected by get_random_int(), since all current range requests are < UINT_MAX. However, we should match caller expectations to avoid coming up short (ha!) in the future. All current callers to randomize_range() chose to use the start address if randomize_range() failed. Therefore, we simplify things by just returning the start address on error. randomize_range() will be removed once all callers have been converted over to randomize_addr().

2016-10-11ACPI / property: Allow holes in reference propertiesMika Westerberg
DT allows holes or empty phandles for references. This is used for example in SPI subsystem where some chip selects are native and others are regular GPIOs. In ACPI _DSD we currently do not support this but instead the preceding reference consumes all following integer arguments. For example we would like to support something like the below ASL fragment for SPI: Package () { "cs-gpios", Package () { ^GPIO, 19, 0, 0, // GPIO CS0 0, // Native CS ^GPIO, 20, 0, 0, // GPIO CS1 } } The zero in the middle means "no entry" or NULL reference. To support this we change acpi_data_get_property_reference() to take firmware node and num_args as argument and rename it to __acpi_node_get_property_reference(). The function returns -ENOENT if the given index resolves to "no entry" reference and -ENODATA when there are no more entries in the property. We then add static inline wrapper acpi_node_get_property_reference() that passes MAX_ACPI_REFERENCE_ARGS as num_args to support the existing behaviour which some drivers have been relying on.

The sub- division support was included in next-20161010 with no reported issues. It passes all unit tests including new tests for all the new functionality below. Summary: - PMEM sub-division support: Allow a single PMEM region to be divided into multiple namespaces. Originally, ~2 years ago, it was thought that partitions of a /dev/pmemX block device could handle sub-allocations of persistent memory for different use cases. With the decision to not support DAX mappings of raw block-devices, and the genesis of device-dax, the need for having multiple pmem-namespace per region has grown. - Device-DAX unified inode: In support of dynamic-resizing of a device-dax instance the kernel arranges for all mappings of a device-dax node to share the same inode. This allows unmap / truncate / invalidation events to affect all instances of the device similar to the behavior of mmap on block devices. - Hardware error scrubbing reworks: The original address-range-scrub and badblocks tracking solution allowed clearing entries at the individual namespace level, but it failed to clear the internal list of media errors maintained at the bus level. The result was that the next scrub or namespace disable/re-enable event would restore the cleared badblocks, but now that is fixed. The v4.8 kernel introduced an auto-scrub-on-machine-check behavior to repopulate the badblocks list. Now, in v4.9, the auto-scrub behavior can be disabled and simply arrange for the error reported in the machine-check to be added to the list. - DIMM health-event notification support: ACPI 6.1 defines a notification event code that can be send to ACPI NVDIMM devices. A poll(2) capable file descriptor for these events can be obtained from the nmemX/nfit/flags sysfs-attribute of a libnvdimm memory device. - Miscellaneous fixes: NVDIMM-N probe error, device-dax build error, and a change to dedup the flush hint list to not flush the memory controller more than necessary" * tag 'libnvdimm-for-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (39 commits) /dev/dax: fix Kconfig dependency build breakage dax: use correct dev_t value dax: convert devm_create_dax_dev to PTR_ERR libnvdimm, namespace: allow creation of multiple pmem-namespaces per region libnvdimm, namespace: lift single pmem limit in scan_labels() libnvdimm, namespace: filter out of range labels in scan_labels() libnvdimm, namespace: enable allocation of multiple pmem namespaces libnvdimm, namespace: update label implementation for multi-pmem libnvdimm, namespace: expand pmem device naming scheme for multi-pmem libnvdimm, region: update nd_region_available_dpa() for multi-pmem support libnvdimm, namespace: sort namespaces by dpa at init libnvdimm, namespace: allow multiple pmem-namespaces per region at scan time tools/testing/nvdimm: support for sub-dividing a pmem region libnvdimm, namespace: unify blk and pmem label scanning libnvdimm, namespace: refactor uuid_show() into a namespace_to_uuid() helper libnvdimm, label: convert label tracking to a linked list libnvdimm, region: move region-mapping input-paramters to nd_mapping_desc nvdimm: reduce duplicated wpq flushes libnvdimm: clear the internal poison_list when clearing badblocks pmem: reduce kmap_atomic sections to the memcpys only ...

2016-10-11PCI: spear: Clean up struct device usageBjorn Helgaas
For consistency with other drivers, use the struct device pointer from struct pcie_port whenever possible instead of relying on the platform_device pointer. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-11PCI: spear: Pass device-specific struct to internal functionsBjorn Helgaas
Only interfaces used from outside the driver, e.g., those called by the DesignWare core, need to accept pointers to the generic struct pcie_port. Internal interfaces can accept pointers to the device-specific struct, which makes them more straightforward. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-11PCI: designware: Simplify pcie_host_ops.readl_rc() and .writel_rc() interfacesBjorn Helgaas
The struct pcie_host_ops.readl_rc() and .writel_rc() function pointers allow a driver to override the default DesignWare register accessors. Make the signature of the override functions the same as the default accessors. This makes the default dw_pcie_readl_rc() and the corresponding override more structurally similar: both will compute the final register address with "pp->dbi_base + reg". Previously dw_pcie_readl_rc() computed the address and passed it to the override. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-10latent_entropy: Mark functions with __latent_entropyEmese Revfy
The __latent_entropy gcc attribute can be used only on functions and variables. If it is on a function then the plugin will instrument it for gathering control-flow entropy. If the attribute is on a variable then the plugin will initialize it with random contents. The variable must be an integer, an integer array type or a structure with integer fields. These specific functions have been selected because they are init functions (to help gather boot-time entropy), are called at unpredictable times, or they have variable loops, each of which provide some level of latent entropy.
