Many architectures have much cheaper ways to handle these\nsituations, but the Linux kernel currently has no portable way\nto make use of them.\n\nThis commit therefore supplies smp_load_acquire() and\nsmp_store_release() to remedy this situation. The new\nsmp_load_acquire() primitive orders the specified load against\nany subsequent reads or writes, while the new smp_store_release()\nprimitive orders the specifed store against any prior reads or\nwrites. These primitives allow array-based circular FIFOs to be\nimplemented without an smp_mb(), and also allow a theoretical\nhole in rcu_assign_pointer() to be closed at no additional\nexpense on most architectures.\n\nIn addition, the RCU experience transitioning from explicit\nsmp_read_barrier_depends() and smp_wmb() to rcu_dereference()\nand rcu_assign_pointer(), respectively resulted in substantial\nimprovements in readability. It therefore seems likely that\nreplacing other explicit barriers with smp_load_acquire() and\nsmp_store_release() will provide similar benefits. It appears\nthat roughly half of the explicit barriers in core kernel code\nmight be so replaced.\n\n[Changelog by PaulMck]\n\nReviewed-by: \"Paul E.

Implemented\n corresponding calls in a few select drivers.\n\n - ACPI GPIO cleanups, refactorings and switch to using the\n descriptor-based interface.\n\n - Support for the TPS80036 Palmas GPIO variant.\n\n - A new driver for the Broadcom Kona GPIO SoC IP block.\n\n - Device tree support for the PCF857x driver.\n\n - A set of ARM GPIO refactorings with the goal of getting rid of a\n bunch of custom GPIO implementations from the arch/arm/* tree:\n\n * Move the IOP GPIO driver to the GPIO subsystem and fix all users\n to use the gpiolib API for accessing GPIOs. Delete the old\n custom GPIO implementation.\n\n * Delete the unused custom PXA GPIO implemention.\n\n * Convert all users of the IXP4 custom GPIO implementation to use\n gpiolib and delete the custom implementation.\n\n * Delete the custom Gemini GPIO implementation, also completely\n unused.\n\n - Various cleanups and renamings\"\n\n* tag \u0027gpio-v3.13-1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (85 commits)\n gpio: gpio-mxs: Remove unneeded dt checks\n gpio: pl061: don\u0027t depend on CONFIG_ARM\n gpio: bcm-kona: add missing .owner to struct gpio_chip\n gpiolib: provide a declaration of seq_file in gpio/driver.h\n gpiolib: include gpio/consumer.h in of_gpio.h for desc_to_gpio()\n gpio: provide stubs for devres gpio functions\n gpiolib: devres: add missing headers\n gpiolib: make GPIO_DEVRES depend on GPIOLIB\n gpiolib: devres: fix devm_gpiod_get_index()\n gpiolib / ACPI: document the GPIO descriptor based interface\n gpiolib / ACPI: allow passing GPIOF_ACTIVE_LOW for GpioInt resources\n gpiolib / ACPI: add ACPI support for gpiod_get_index()\n gpiolib / ACPI: convert to gpiod interfaces\n gpiolib: add gpiod_get() and gpiod_put() functions\n gpiolib: port of_ functions to use gpiod\n gpiolib: export descriptor-based GPIO interface\n Fixup \"MAINTAINERS: GPIO-INTEL-MID: add maintainer\"\n gpio: bcm281xx: Don\u0027t print addresses of GPIO area in probe()\n gpio: tegra: use new gpio_lock_as_irq() API\n gpio: rcar: Include linux/of.h header\n ...\n" }, { "commit": "8a5dc585d50015af9c079ae2d182dc4c1cd22914", "tree": "7544d20587e589bf20c526a5f83205e113cc3e58", "parents": [ "eeab517b68beb9e044e869bee18e3bdfa60e5aca", "9da8312048edcf246ac1d7ab6aa0293f252de559" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Nov 12 15:40:03 2013 +0900" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Nov 12 15:40:03 2013 +0900" }, "message": "Merge tag \u0027pinctrl-for-v3.13-1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl\n\nPull pin control updates from Linus Walleij:\n \"Main pin control pull request for the v3.13 cycle.\n\n The changes hitting arch/blackfin are ACKed by the Blackfin\n maintainer, and the device tree bindings are ACKed to the extent\n possible by someone from the device tree maintainers group.\n\n - Blackfin ADI pin control driver, we move yet another architecture\n under this subsystem umbrella.\n\n - Incremental updates to the Renesas Super-H PFC pin control driver.\n New subdriver for the r8a7791 SoC.\n\n - Non-linear GPIO ranges from the gpiolib side of things, this\n enabled simplified device tree bindings by referring entire groups\n of pins on some pin controller to act as back-end for a certain\n GPIO-chip driver.\n\n - Add the Abilis TB10x pin control driver used on the ARC\n architecture.

This only occurs on a very specific repository and can be\n reproduced stably on two independent laptops. Git mailing list ran\n out of ideas and for me this looks like some very exotic kernel issue\"\n\nand bisected the failure to the backport of commit 53a59fc67f97 (\"mm:\nlimit mmu_gather batching to fix soft lockups on !CONFIG_PREEMPT\").\n\nThat commit itself is not actually buggy, but what it does is to make it\nmuch more likely to hit the partial TLB invalidation case, since it\nintroduces a new case in tlb_next_batch() that previously only ever\nhappened when running out of memory.\n\nThe real bug is that the TLB gather virtual memory range setup is subtly\nbuggered. It was introduced in commit 597e1c3580b7 (\"mm/mmu_gather:\nenable tlb flush range in generic mmu_gather\"), and the range handling\nwas already fixed at least once in commit e6c495a96ce0 (\"mm: fix the TLB\nrange flushed when __tlb_remove_page() runs out of slots\"), but that fix\nwas not complete.\n\nThe problem with the TLB gather virtual address range is that it isn\u0027t\nset up by the initial tlb_gather_mmu() initialization (which didn\u0027t get\nthe TLB range information), but it is set up ad-hoc later by the\nfunctions that actually flush the TLB. And so any such case that forgot\nto update the TLB range entries would potentially miss TLB invalidates.\n\nRather than try to figure out exactly which particular ad-hoc range\nsetup was missing (I personally suspect it\u0027s the hugetlb case in\nzap_huge_pmd(), which didn\u0027t have the same logic as zap_pte_range()\ndid), this patch just gets rid of the problem at the source: make the\nTLB range information available to tlb_gather_mmu(), and initialize it\nwhen initializing all the other tlb gather fields.\n\nThis makes the patch larger, but conceptually much simpler. And the end\nresult is much more understandable; even if you want to play games with\npartial ranges when invalidating the TLB contents in chunks, now the\nrange information is always there, and anybody who doesn\u0027t want to\nbother with it won\u0027t introduce subtle bugs.\n\nBen verified that this fixes his problem.\n\nReported-bisected-and-tested-by: Ben Tebulin \u003ctebulin@googlemail.com\u003e\nBuild-testing-by: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nBuild-testing-by: Richard Weinberger \u003crichard.weinberger@gmail.com\u003e\nReviewed-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: stable@vger.kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a5725ac23bf4ff79656ac2c317c323e261327fb3", "tree": "279ff31bbb6cac44de3c1ef3f66d347da0fe5b36", "parents": [ "a703f9b72407d9a4e233f4f6aea1a14ab2b74415" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Tue Jul 16 18:50:52 2013 +0200" }, "committer": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Wed Aug 14 17:14:53 2013 +0200" }, "message": "vtime: Describe overriden functions in dedicated arch headers\n\nIf the arch overrides some generic vtime APIs, let it describe\nthese on a dedicated and standalone header.

A periodic timer tick at\n HZ\u003d1000 can cause a constant overhead of up to 1.0%. This feature\n removes that overhead - and speeds up the system by 0.5%-1.0% on\n typical distro configs even on modern systems.\n\n - Real-time workload latency reduction: CPUs running critical tasks\n should experience as little jitter as possible. The last remaining\n source of kernel-related jitter was the periodic timer tick.\n\n - A single task executing on a CPU is a pretty common situation,\n especially with an increasing number of cores/CPUs, so this feature\n helps desktop and mobile workloads as well.\n\n The cost of the feature is mainly related to increased timer\n reprogramming overhead when a CPU switches its tick period, and thus\n slightly longer to-idle and from-idle latency.\n\n Configuration-wise a third mode of operation is added to the existing\n two NOHZ kconfig modes:\n\n - CONFIG_HZ_PERIODIC: [formerly !CONFIG_NO_HZ], now explicitly named\n as a config option. This is the traditional Linux periodic tick\n design: there\u0027s a HZ tick going on all the time, regardless of\n whether a CPU is idle or not.\n\n - CONFIG_NO_HZ_IDLE: [formerly CONFIG_NO_HZ\u003dy], this turns off the\n periodic tick when a CPU enters idle mode.\n\n - CONFIG_NO_HZ_FULL: this new mode, in addition to turning off the\n tick when a CPU is idle, also slows the tick down to 1 Hz (one\n timer interrupt per second) when only a single task is running on a\n CPU.\n\n The .config behavior is compatible: existing !CONFIG_NO_HZ and\n CONFIG_NO_HZ\u003dy settings get translated to the new values, without the\n user having to configure anything. CONFIG_NO_HZ_FULL is turned off by\n default.\n\n This feature is based on a lot of infrastructure work that has been\n steadily going upstream in the last 2-3 cycles: related RCU support\n and non-periodic cputime support in particular is upstream already.\n\n This tree adds the final pieces and activates the feature. The pull\n request is marked RFC because:\n\n - it\u0027s marked 64-bit only at the moment - the 32-bit support patch is\n small but did not get ready in time.\n\n - it has a number of fresh commits that came in after the merge\n window. The overwhelming majority of commits are from before the\n merge window, but still some aspects of the tree are fresh and so I\n marked it RFC.\n\n - it\u0027s a pretty wide-reaching feature with lots of effects - and\n while the components have been in testing for some time, the full\n combination is still not very widely used. That it\u0027s default-off\n should reduce its regression abilities and obviously there are no\n known regressions with CONFIG_NO_HZ_FULL\u003dy enabled either.\n\n - the feature is not completely idempotent: there is no 100%\n equivalent replacement for a periodic scheduler/timer tick. In\n particular there\u0027s ongoing work to map out and reduce its effects\n on scheduler load-balancing and statistics.
