2010-05-17ARM: 6136/1: ARCH_REQUIRE_GPIOLIB selects GENERIC_GPIOHartley Sweeten
The ARCH_REQUIRE_GPIOLIB config option will select GPIOLIB which in turn will select GENERIC_GPIO. Because of this, there is no reason to do the select GENERIC_GPIO in arch/arm/Kconfig for the architectures that have ARCH_REQUIRE_GPIOLIB.

2010-05-17ARM: 6074/1: oprofile: convert from sysdev to platform deviceWill Deacon
This is a reworking of an original patch posted by Aaro Koskinen: oprofile does not work with PM, because sysdev_suspend() is done with interrupts disabled and oprofile needs a mutex. Implementing oprofile as a platform device solves this problem.

2010-05-17ARM: 6073/1: oprofile: remove old files and update KConfigWill Deacon
Enable hardware perf-events if CPU_HAS_PMU and select HAVE_OPROFILE if HAVE_PERF_EVENTS. If no hardware support is present, OProfile will fall back to timer mode. This patch also removes the old OProfile drivers in favour of the code implemented by perf. Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-05-17ARM: 6072/1: oprofile: use perf-events framework as backendWill Deacon
There are currently two hardware performance monitoring subsystems in the kernel for ARM: OProfile and perf-events. This creates the following problems: 1.) Duplicate PMU accessor code. Inevitable code drift may lead to bugs in one framework that are fixed in the other. 2.) Locking issues. OProfile doesn't reprogram hardware counters between profiling runs if the events to be monitored have not been changed. This means that other profiling frameworks cannot use the counters if OProfile is in use. 3.) Due to differences in the two frameworks, it may not be possible to compare the results obtained by OProfile with those obtained by perf. This patch removes the OProfile PMU driver code and replaces it with calls to perf, therefore solving the issues mentioned above. The only userspace-visible change is the lack of SCU counter support for 11MPCore. This is currently unsupported by OProfile userspace tools anyway and therefore shouldn't cause any problems.

2010-05-17ARM: 6071/1: perf-events: allow modules to query the number of hardware countersWill Deacon
For OProfile to initialise oprofilefs correctly, it needs to know the number of counters it can represent. This patch adds a function to the ARM perf-events backend to return the number of hardware counters available for the current PMU.

2010-05-17ARM: 6070/1: perf-events: add support for xscale PMUsWill Deacon
The perf-events framework for ARM only supports v6 and v7 cores. This patch adds support for xscale v1 and v2 PMUs to perf, based on the OProfile drivers in arch/arm/oprofile/op_model_xscale.c Signed-off-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-05-17ARM: 6069/1: perf-events: use numeric ID to identify PMUWill Deacon
The ARM perf-events framework provides support for a number of different PMUs using struct arm_pmu. The char *name field of this struct can be used to identify the PMU, but this is cumbersome if used outside of perf. This patch replaces the name string for a PMU with an enum, which holds a unique ID for the PMU being represented. This ID can be used to index an array of names within perf, so no functionality is lost. The presence of the ID field, allows other kernel subsystems [currently oprofile] to use their own mappings for the PMU name.

2010-05-17ARM: 6064/1: pmu: register IRQs at runtimeWill Deacon
The current PMU infrastructure for ARM requires that the IRQs for the PMU device are fixed at compile time and are selected based on the ARCH_ or MACH_ flags. This has the disadvantage of tying the Kernel down to a particular board as far as profiling is concerned. This patch replaces the compile-time IRQ registration with a runtime mechanism which allows the IRQs to be registered with the framework as a platform_device. A further advantage of this change is that there is scope for registering different types of performance counters in the future by changing the id of the platform_device and attaching different resources to it.

2010-05-17ARM: Optionally allow ARMv6 to use 'normal, bufferable' memory for DMARussell King
Provide a configuration option to allow the ARMv6 to use normal bufferable memory for coherent DMA. This option is forced to 'y' for ARMv7, and offered as a configuration option on ARMv6. Enabling this option requires drivers to have the necessary barriers to ensure that data in DMA coherent memory is visible prior to the DMA operation commencing.

2010-05-15ARM: 6134/1: Handle instruction cache maintenance fault properlyKirill A. Shutemov
Between "clean D line..." and "invalidate I line" operations in v7_coherent_user_range(), the memory page may get swapped out. And the fault on "invalidate I line" could not be properly handled causing the oops. In ARMv6 "external abort on linefetch" replaced by "instruction cache maintenance fault". Let's handle it as translation fault. It fixes the issue. I'm not sure if it's reasonable to check arch version in run-time. Let's do it in compile time for now.
