Currently the tools/vm Makefile has a rather arbitrary implicit build rule; page-types is the first value in TARGETS so lets just build that one! Additionally there is no install rule and this is needed for make -C tools vm_install to work properly. Provide a more sensible implicit build rule and a new install rule.

2017-02-22dax: add tracepoint infrastructure, PMD tracingRoss Zwisler3-10/+113
Tracepoints are the standard way to capture debugging and tracing information in many parts of the kernel, including the XFS and ext4 filesystems. Create a tracepoint header for FS DAX and add the first DAX tracepoints to the PMD fault handler. This allows the tracing for DAX to be done in the same way as the filesystem tracing so that developers can look at them together and get a coherent idea of what the system is doing. I added both an entry and exit tracepoint because future patches will add tracepoints to child functions of dax_iomap_pmd_fault() like dax_pmd_load_hole() and dax_pmd_insert_mapping(). We want those messages to be wrapped by the parent function tracepoints so the code flow is more easily understood. Having entry and exit tracepoints for faults also allows us to easily see what filesystems functions were called during the fault. These filesystem functions get executed via iomap_begin() and iomap_end() calls, for example, and will have their own tracepoints. For PMD faults we primarily want to understand the type of mapping, the fault flags, the faulting address and whether it fell back to 4k faults. If it fell back to 4k faults the tracepoints should let us understand why. I named the new tracepoint header file "fs_dax.h" to allow for device DAX to have its own separate tracing header in the same directory at some point. Here is an example output for these events from a successful PMD fault: big-1441 [005] .... 32.582758: xfs_filemap_pmd_fault: dev 259:0 ino 0x1003 big-1441 [005] .... 32.582776: dax_pmd_fault: dev 259:0 ino 0x1003 shared WRITE|ALLOW_RETRY|KILLABLE|USER address 0x10505000 vm_start 0x10200000 vm_end 0x10700000 pgoff 0x200 max_pgoff 0x1400 big-1441 [005] .... 32.583292: dax_pmd_fault_done: dev 259:0 ino 0x1003 shared WRITE|ALLOW_RETRY|KILLABLE|USER address 0x10505000 vm_start 0x10200000 vm_end 0x10700000 pgoff 0x200 max_pgoff 0x1400 NOPAGE Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Ross Zwisler <[email protected]> Suggested-by: Dave Chinner <[email protected]> Reviewed-by: Jan Kara <[email protected]> Acked-by: Steven Rostedt <[email protected]> Cc: Dave Jiang <[email protected]> Cc: Matthew Wilcox <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2017-02-22tracing: add __print_flags_u64()Ross Zwisler3-0/+53
Patch series "DAX tracepoints, mm argument simplification", v4. This contains both my DAX tracepoint code and Dave Jiang's MM argument simplifications. Dave's code was written with my tracepoint code as a baseline, so it seemed simplest to keep them together in a single series. This patch (of 7): Add __print_flags_u64() and the helper trace_print_flags_seq_u64() in the same spirit as __print_symbolic_u64() and trace_print_symbols_seq_u64(). These functions allow us to print symbols associated with flags that are 64 bits wide even on 32 bit machines. These will be used by the DAX code so that we can print the flags set in a pfn_t such as PFN_SG_CHAIN, PFN_SG_LAST, PFN_DEV and PFN_MAP. Without this new function I was getting errors like the following when compiling for i386: include/linux/pfn_t.h:13:22: warning: large integer implicitly truncated to unsigned type [-Woverflow] #define PFN_SG_CHAIN (1ULL << (BITS_PER_LONG_LONG - 1)) ^ Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Ross Zwisler <[email protected]> Reviewed-by: Steven Rostedt <[email protected]> Cc: Dave Chinner <[email protected]> Cc: Dave Jiang <[email protected]> Cc: Jan Kara <[email protected]> Cc: Matthew Wilcox <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2017-02-23seccomp: Only dump core when single-threadedKees Cook1-5/+8
The SECCOMP_RET_KILL filter return code has always killed the current thread, not the entire process. Changing this as a side-effect of dumping core isn't a safe thing to do (a few test suites have already flagged this behavioral change). Instead, restore the RET_KILL semantics, but still dump core when a RET_KILL delivers SIGSYS to a single-threaded process.

2017-02-22ALSA: usb-audio: Fix memory leak and corruption in mixer_us16x08.cTakashi Iwai2-54/+39
There are a few places leaking memory and doing double-free in mixer_us16x08.c. The driver allocates a usb_mixer_elem_info object at each add_new_ctl() call. This has to be freed via kctl->private_free, but currently this is done properly only for some controls. Also, the driver allocates three external objects (comp_store, eq_store, meter_store), and these are referred in elem->private_data (it's not kctl->private_data). And these have to be released, but there are none doing it. Moreover, these extra objects have to be released only once. Thus the release should be done only by the first kctl element that refers to it. For fixing these, we call either snd_usb_mixer_elem_free() (only for kctl->private_data) or elem_private_free() (for both kctl->private_data and elem->private_data) via kctl->private_free appropriately. Last but not least, snd_us16x08_controls_create() may return in the middle without releasing the allocated *_store objects due to an error. For fixing this, we shuffle the allocation code so that it's called just before its reference.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "Pin control bulk changes for the v4.11 kernel cycle. Core changes: - Switch the generic pin config argument from 16 to 24 bits, only use 8 bits for the configuration type. We might need to encode more information about a certain setting than we need to encode different generic settings. - Add a cross-talk API to the pin control GPIO back-end, utilizing pinctrl_gpio_set_config() from GPIO drivers that want to set up a certain pin configuration in the back-end. This also includes the .set_config() refactoring of the GPIO chips, so that they pass a generic configuration for things like debouncing and single ended (typically open drain). This change has also been merged in an immutable branch to the GPIO tree. - Take hogs with a delayed work, so that we finalize probing a pin controller before trying to get any hogs. - For pin controllers putting all group and function definitions into the device tree, we now have generic code to deal with this and it is used in two drivers so far. - Simplifications of the pin request conflict check. - Make dt_free_map() optional. Updates to drivers: - pinctrl-single now use the generic helpers to generate dynamic group and function tables from the device tree. - Texas Instruments IOdelay configuration driver add-on to pinctrl-single. - i.MX: use radix trees to store groups and functions, use the new generic group and function helpers to manage them. - Intel: add support for hardware debouncing and 1K pull-down. New subdriver for the Gemini Lake SoC. - Renesas SH-PFC: drive strength and bias support, CAN bus muxing, MSIOF, SDHI, HSCIF for r8a7796.

Fix mux configuration on GPIOs. Add banks Y, Z, AA, AB and AC. - AMD: support additional GPIO. - STM32: set this controller to strict muxing mode. STM32H743 MCU support. - Allwinner sunxi: deep simplifications on how to support subvariants of SoCs without adding to much SoC-specific data for each subvariant, especially for sun5i variants.

Add pwm_ao_b pin. - Qualcomm: use raw spinlock variants: this makes the qualcomm driver realtime-safe" * tag 'pinctrl-v4.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (111 commits) pinctrl: samsung: Fix return value check in samsung_pinctrl_get_soc_data() pinctrl: intel: unlock on error in intel_config_set_pull() pinctrl: berlin: make bool drivers explicitly non-modular pinctrl: spear: make bool drivers explicitly non-modular pinctrl: mvebu: make bool drivers explicitly non-modular pinctrl: sunxi: make sun5i explicitly non-modular pinctrl: sunxi: Remove stray printk call in sun5i driver's probe function pinctrl: samsung: mark PM functions as __maybe_unused pinctrl: sunxi: Remove redundant A31s pinctrl driver pinctrl: sunxi: Support A31/A31s with pinctrl variants pinctrl: Amend bindings for STM32 pinctrl pinctrl: Add STM32 pinctrl driver DT bindings pinctrl: stm32: Add STM32H743 MCU support include: dt-bindings: Add STM32H7 pinctrl DT defines gpio: aspeed: Remove dependence on GPIOF_* macros pinctrl: stm32: fix bad location of gpiochip_lock_as_irq drivers: pinctrl: add driver for Allwinner H5 SoC pinctrl: intel: Add Intel Gemini Lake pin controller support pinctrl: intel: Add support for 1k additional pull-down pinctrl: intel: Add support for hardware debouncer ...
2017-02-22HID: rmi: fallback to generic/multitouch if hid-rmi is not builtJiri Kosina1-1/+2
Commit 279967a65b32 ("HID: rmi: Handle all Synaptics touchpads using hid-rmi") unconditionally switches over handling of all Synaptics touchpads to hid-rmi (to make use of extended features of the HW); in case CONFIG_HID_RMI is disabled though this renders the touchpad unusable, as the HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID) match doesn't exist and generic/multitouch doesn't bind to it either (due to hid group mismatch). Fix this by switching over to hid-rmi only if it has been actually built.

2017-02-21ALSA: x86: hdmi: select CONFIG_SND_PCMArnd Bergmann1-0/+1
The newly added driver uses the PCM helpers and fails to link if they are disabled: sound/built-in.o: In function `hdmi_lpe_audio_runtime_suspend': intel_hdmi_audio.c:(.text+0x15906): undefined reference to `snd_pcm_suspend' sound/built-in.o: In function `had_pcm_hw_params': intel_hdmi_audio.c:(.text+0x15ac7): undefined reference to `snd_pcm_lib_malloc_pages' sound/built-in.o: In function `had_pcm_open': intel_hdmi_audio.c:(.text+0x15d49): undefined reference to `snd_pcm_hw_constraint_integer' This uses a Kconfig 'select' statement to make sure they are enabled.
