2016-09-06ARM: 8611/1: l2x0: add PMU supportMark Rutland
The L2C-220 (AKA L220) and L2C-310 (AKA PL310) cache controllers feature a Performance Monitoring Unit (PMU), which can be useful for tuning and/or debugging. This hardware is always present and the relevant registers are accessible to non-secure accesses. Thus, no special firmware interface is necessary. This patch adds support for the PMU, plugging into the usual perf infrastructure. The overflow interrupt is not always available (e.g. on RealView PBX A9 it is not wired up at all), and the hardware counters saturate, so the driver does not make use of this. Instead, the driver periodically polls and reset counters as required to avoid losing events due to saturation.

Add these two new api callbacks to struct ulpi_ops. These are different than read, write in that they pass the parent device directly instead of via the ops argument.

2016-09-05efi/libstub: Introduce ExitBootServices helperJeffrey Hugo
The spec allows ExitBootServices to fail with EFI_INVALID_PARAMETER if a race condition has occurred where the EFI has updated the memory map after the stub grabbed a reference to the map. The spec defines a retry proceedure with specific requirements to handle this scenario. This scenario was previously observed on x86 - commit d3768d885c6c ("x86, efi: retry ExitBootServices() on failure") but the current fix is not spec compliant and the scenario is now observed on the Qualcomm Technologies QDF2432 via the FDT stub which does not handle the error and thus causes boot failures. The user will notice the boot failure as the kernel is not executed and the system may drop back to a UEFI shell, but will be unresponsive to input and the system will require a power cycle to recover. Add a helper to the stub library that correctly adheres to the spec in the case of EFI_INVALID_PARAMETER from ExitBootServices and can be universally used across all stub implementations.

2016-09-05efi/libstub: Allocate headspace in efi_get_memory_map()Jeffrey Hugo
efi_get_memory_map() allocates a buffer to store the memory map that it retrieves. This buffer may need to be reused by the client after ExitBootServices() is called, at which point allocations are not longer permitted. To support this usecase, provide the allocated buffer size back to the client, and allocate some additional headroom to account for any reasonable growth in the map that is likely to happen between the call to efi_get_memory_map() and the client reusing the buffer.

2016-09-05power: supply: bq24735-charger: Request status GPIO with initial input setupPaul Kocialkowski
This requests the status GPIO with initial input setup. It is required to read the GPIO status at probe time and thus correctly avoid sending I2C messages when AC is not plugged. When requesting the GPIO without initial input setup, it always reads 0 which causes probe to fail as it assumes the charger is connected, sends I2C messages and fails. While at it, this switches the driver over to gpiod API. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Signed-off-by: Sebastian Reichel <sre@kernel.org>

2016-09-05locking/barriers: Don't use sizeof(void) in lockless_dereference()Johannes Berg
My previous commit: 112dc0c8069e ("locking/barriers: Suppress sparse warnings in lockless_dereference()") caused sparse to complain that (in radix-tree.h) we use sizeof(void) since that rcu_dereference()s a void *. Really, all we need is to have the expression *p in here somewhere to make sure p is a pointer type, and sizeof(*p) was the thing that came to my mind first to make sure that's done without really doing anything at runtime. Another thing I had considered was using typeof(*p), but obviously we can't just declare a typeof(*p) variable either, since that may end up being void. Declaring a variable as typeof(*p)* gets around that, and still checks that typeof(*p) is valid, so do that. This type construction can't be done for _________p1 because that will actually be used and causes sparse address space warnings, so keep a separate unused variable for it.

2016-09-04af_unix: split 'u->readlock' into two: 'iolock' and 'bindlock'Linus Torvalds
Right now we use the 'readlock' both for protecting some of the af_unix IO path and for making the bind be single-threaded. The two are independent, but using the same lock makes for a nasty deadlock due to ordering with regards to filesystem locking. The bind locking would want to nest outside the VSF pathname locking, but the IO locking wants to nest inside some of those same locks. We tried to fix this earlier with commit c845acb324aa ("af_unix: Fix splice-bind deadlock") which moved the readlock inside the vfs locks, but that caused problems with overlayfs that will then call back into filesystem routines that take the lock in the wrong order anyway. Splitting the locks means that we can go back to having the bind lock be the outermost lock, and we don't have any deadlocks with lock ordering.

2016-09-03iio: trigger: allow immutable triggers to be assignedMatt Ranostay
There are times when an assigned trigger to a device shouldn't ever change after intialization. Examples of this being used is when an provider device has a trigger that is assigned to an ADC, which uses it populate data into a callback buffer.

2016-09-03bcma: support BCM53573 series of wireless SoCsRafał Miłecki
BCM53573 seems to be the first series of Northstar family with wireless on the chip. The base models are BCM53573-s (A0, A1) and there is also BCM47189B0 which seems to be some small modification. The only problem with these chipsets seems to be watchdog. It's totally unavailable on 53573A0 / 53573A1 and preferable PMU watchdog is broken on 53573B0 / 53573B1.

2016-09-02ACPI / drivers: fix typo in ACPI_DECLARE_PROBE_ENTRY macroLorenzo Pieralisi
When the ACPI_DECLARE_PROBE_ENTRY macro was added in commit e647b532275b ("ACPI: Add early device probing infrastructure"), a stub macro adding an unused entry was added for the !CONFIG_ACPI Kconfig option case to make sure kernel code making use of the macro did not require to be guarded within CONFIG_ACPI in order to be compiled. The stub macro was never used since all kernel code that defines ACPI_DECLARE_PROBE_ENTRY entries is currently guarded within CONFIG_ACPI; it contains a typo that should be nonetheless fixed. Fix the typo in the stub (ie !CONFIG_ACPI) ACPI_DECLARE_PROBE_ENTRY() macro so that it can actually be used if needed.

2016-09-02genirq/generic_chip: Verify irqs_per_chip <= 32Sebastian Frias
Most (if not all) code here implicitly assumes that the maximum number of IRQs per chip will be 32, and thus uses 'u32' or 'unsigned long' for many tasks (for example "struct irq_data" declares its 'mask' field as 'u32', and "struct irq_chip_generic" declares its 'installed' field as 'unsigned long') However, there is no check to verify that irqs_per_chip is <= 32. Hence, calling irq_alloc_domain_generic_chips() with a bigger value will result in unexpected results. Provide a wrapper with a MAYBE_BUILD_BUG_ON(nrirqs >= 32) to catch such cases.
