2014-09-04nohz: Restore NMI safe local irq work for local nohz kickFrederic Weisbecker
The local nohz kick is currently used by perf which needs it to be NMI-safe. Recent commit though (7d1311b93e58ed55f3a31cc8f94c4b8fe988a2b9) changed its implementation to fire the local kick using the remote kick API. It was convenient to make the code more generic but the remote kick isn't NMI-safe.

2014-09-03ACPI / scan: not cache _SUN value in struct acpi_device_pnpYasuaki Ishimatsu
The _SUN device indentification object is not guaranteed to return the same value every time it is executed, so we should not cache its return value, but rather execute it every time as needed. If it is cached, an incorrect stale value may be used in some situations. This issue was exposed by commit 202317a573b2 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace). Fix it by avoiding to cache the return value of _SUN.

2014-09-02Revert "leds: convert blink timer to workqueue"Jiri Kosina
This reverts commit 8b37e1bef5a6b60e949e28a4db3006e4b00bd758. It's broken as it changes led_blink_set() in a way that it can now sleep (while synchronously waiting for workqueue to be cancelled). That's a problem, because it's possible that this function gets called from atomic context (tpt_trig_timer() takes a readlock and thus disables preemption). This has been brought up 3 weeks ago already [1] but no proper fix has materialized, and I keep seeing the problem since 3.17-rc1.

2014-09-02gpio: move varargs hack outside #ifdef GPIOLIBLinus Walleij
commit 39b2bbe3d715cf5013b5c48695ccdd25bd3bf120 "gpio: add flags argument to gpiod_get*() functions" added a dynamic flags argument to all the GPIOD getter functions, however this did not cover the stubs so when people used gpiod stubs to compile out descriptor code, compilation failed. Solve this by: - Also rename all the stub functions __gpiod_* - Moving the vararg hack outside of #ifdef CONFIG_GPIOLIB so these will always be available.

2014-08-28jbd2: fix descriptor block size handling errors with journal_csumDarrick J. Wong
It turns out that there are some serious problems with the on-disk format of journal checksum v2. The foremost is that the function to calculate descriptor tag size returns sizes that are too big. This causes alignment issues on some architectures and is compounded by the fact that some parts of jbd2 use the structure size (incorrectly) to determine the presence of a 64bit journal instead of checking the feature flags. Therefore, introduce journal checksum v3, which enlarges the descriptor block tag format to allow for full 32-bit checksums of journal blocks, fix the journal tag function to return the correct sizes, and fix the jbd2 recovery code to use feature flags to determine 64bitness. Add a few function helpers so we don't have to open-code quite so many pieces. Switching to a 16-byte block size was found to increase journal size overhead by a maximum of 0.1%, to convert a 32-bit journal with no checksumming to a 32-bit journal with checksum v3 enabled.

2014-08-25mtd: nand: omap: Revert to using software ECC by defaultRoger Quadros
For v3.12 and prior, 1-bit Hamming code ECC via software was the default choice. Commit c66d039197e4 in v3.13 changed the behaviour to use 1-bit Hamming code via Hardware using a different ECC layout i.e. (ROM code layout) than what is used by software ECC. This ECC layout change causes NAND filesystems created in v3.12 and prior to be unusable in v3.13 and later. So revert back to using software ECC by default if an ECC scheme is not explicitely specified.

The design assumed that the two tracers could never run simultaneously as only one tracer can be used at a time. The problem with this assumption was that the function profiler could be implemented on top of the function graph tracer, and the function profiler could run at the same time as the function tracer. This caused the assumption to be broken and when ftrace detected this failed assumpiton it would spit out a nasty warning and shut itself down. Instead of using a single ftrace_ops that switches between the function and function_graph callbacks, the two tracers can again use their own ftrace_ops. But instead of having a complex hierarchy of ftrace_ops, the filter fields are placed in its own structure and the ftrace_ops can carefully use the same filter. This change took a bit to be able to allow for this and currently only the global_ops can share the same filter, but this new design can easily be modified to allow for any ftrace_ops to share its filter with another ftrace_ops. The first four patches deal with the change of allowing the ftrace_ops to share the filter (and this needs to go to 3.16 as well). The fifth patch fixes a bug that was also caused by the new changes but only for archs other than x86, and only if those archs implement a direct call to the function_graph tracer which they do not do yet but will in the future. It does not need to go to stable, but needs to be fixed before the other archs update their code to allow direct calls to the function_graph trampoline" * tag 'trace-fixes-v3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Use current addr when converting to nop in __ftrace_replace_code() ftrace: Fix function_profiler and function tracer together ftrace: Fix up trampoline accounting with looping on hash ops ftrace: Update all ftrace_ops for a ftrace_hash_ops update ftrace: Allow ftrace_ops to use the hashes from other ops

2014-08-22ftrace: Allow ftrace_ops to use the hashes from other opsSteven Rostedt (Red Hat)
Currently the top level debug file system function tracer shares its ftrace_ops with the function graph tracer. This was thought to be fine because the tracers are not used together, as one can only enable function or function_graph tracer in the current_tracer file. But that assumption proved to be incorrect. The function profiler can use the function graph tracer when function tracing is enabled. Since all function graph users uses the function tracing ftrace_ops this causes a conflict and when a user enables both function profiling as well as the function tracer it will crash ftrace and disable it. The quick solution so far is to move them as separate ftrace_ops like it was earlier. The problem though is to synchronize the functions that are traced because both function and function_graph tracer are limited by the selections made in the set_ftrace_filter and set_ftrace_notrace files. To handle this, a new structure is made called ftrace_ops_hash. This structure will now hold the filter_hash and notrace_hash, and the ftrace_ops will point to this structure. That will allow two ftrace_ops to share the same hashes. Since most ftrace_ops do not share the hashes, and to keep allocation simple, the ftrace_ops structure will include both a pointer to the ftrace_ops_hash called func_hash, as well as the structure itself, called local_hash. When the ops are registered, the func_hash pointer will be initialized to point to the local_hash within the ftrace_ops structure. Some of the ftrace internal ftrace_ops will be initialized statically. This will allow for the function and function_graph tracer to have separate ops but still share the same hash tables that determine what functions they trace.
