Pull clk updates from Stephen Boyd: "This is a fairly quiet release. We don't have any patches to the core framework. The only patch that can even be considered "core" adds another clk_get() variant. The rest of the changes are in drivers for various SoCs, and we have a few bits for ARM shmobile architecture code (dts and mach) due to the dependency we're breaking between shmobile architecture code and its clk driver. Those shmobile bits have also been pulled into arm-soc tree. Here's the summary: Core: - Support for devm_get_clk_from_child() used with DT bindings that have subnodes with the 'clocks' property New Drivers: - Allwinner A64 (sun50i) - i.MX imx6ull - Socionext's UniPhier SoC CPUs - Mediatek MT2701 SoCs - Rockchip rk1108 SoCs - Qualcomm MSM8994/MSM8992 SoCS - Qualcomm RPM Clocks - Hisilicon Hi3516CV300 and Hi3798CV200 CRG - Oxford Semiconductor OX820 and OX810SE SoCs - Renesas RZ/G1M and RZ/GIE SoCs - Renesas R-Car RST driver for mode pin states Updates: - Four Allwinner SoCs are migrated to the new style clk driver - Rockchip rk3399,rk3066 PLL optimizations - i.MX LVDS display glitch fixes and AV PLL precision improvements - Qualcomm MSM8996 GPU GDSCs, hw controlled GDSCs, and Alpha PLL support - Explicit demodularization of always builtin drivers - Freescale Qoriq ls1012a and ls1046a support - Exynos 5433 parent typo fix and critical clock tagging - Renesas r8a7743/r8a7745 CPG - Renesas R-Car M3-W CSI2/VIN/SYS-DMAC/(H)SCIF/I2C/DRIF/gfx support - stm32f4* LSI, LSE, RTC, and QSPI clocks - pxa27x and pxa25x cpufreq as clks - TI omap36xx sprz319 advisory 2.1 workaround - Broadcom bcm2835 rate change propogation to PLLH_AUX from VEC" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (150 commits) clk: bcm: Fix 'maybe-uninitialized' warning in bcm2835_clock_choose_div_and_prate() clk: add devm_get_clk_from_child() API clk: st: clk-flexgen: Unmap region obtained by of_iomap clk: keystone: pll: Unmap region obtained by of_iomap clk:mmp:clk-of-mmp2: Free memory and Unmap region obtained by kzalloc and of_iomap clk:mmp:clk-of-pxa910: Free memory and Unmap region obtained by kzmalloc and of_iomap clk: mmp: clk-of-pxa1928: Free memory obtained by kzalloc clk: cdce925: Fix limit check clk: bcm: Make COMMON_CLK_IPROC into a library clk: qoriq: added ls1012a clock configuration clk: ti: dra7: fix "failed to lookup clock node gmac_gmii_ref_clk_div" boot message clk: bcm: Allow rate change propagation to PLLH_AUX on VEC clock clk: bcm: Support rate change propagation on bcm2835 clocks clk: bcm2835: Avoid overwriting the div info when disabling a pll_div clk clk: ti: omap36xx: Work around sprz319 advisory 2.1 clk: clk-wm831x: fix a logic error clk: uniphier: add cpufreq data for LD11, LD20 SoCs clk: uniphier: add CPU-gear change (cpufreq) support clk: qcom: Put venus core0/1 gdscs to hw control mode clk: qcom: gdsc: Add support for gdscs with HW control ... -

Pull remoteproc updates from Bjorn Andersson: - introduce remoteproc "subdevice" support, which allows remoteproc driver to associate devices to the "running" state of the remoteproc, allowing devices to be probed and removed as the remote processor is booted, shut down or recovering from a crash. - handling of virtio device resources was improved, vring memory is now allocated as part of other memory allocation. This ensures that all vrings for all virtio devices are allocated before we boot the remote processor. - the debugfs mechanism for starting and stopping remoteproc instances was replaced with a sysfs interface, also providing a mechanism for specifying firmware to use by the instance. This allows user space to load and boot use case specific firmware on remote processors. - new drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as removal of the unused StE modem loader. - finally support for crash recovery in the Qualcomm Wirelss subsystem (used for WiFi/BT/FM on a number of platforms) and a number of bug fixes and cleanups * tag 'rproc-v4.10' of git://github.com/andersson/remoteproc: (49 commits) remoteproc: qcom_adsp_pil: select qcom_scm remoteproc: Drop wait in __rproc_boot() remoteproc/ste: Delete unused driver remoteproc: Remove "experimental" warning remoteproc: qcom_adsp_pil: select qcom_scm dt-binding: soc: qcom: smd: Add label property remoteproc: qcom: mdt_loader: add include for sizes remoteproc: Update last rproc_put users to rproc_free remoteproc: qcom: adsp: Add missing MODULE_DEVICE_TABLE remoteproc: wcnss-pil: add QCOM_SMD dependency dmaengine: st_fdma: Revert: "Revert: Update st_fdma to 'depends on REMOTEPROC'" remoteproc: Add support for xo clock remoteproc: adsp-pil: fix recursive dependency remoteproc: Introduce Qualcomm ADSP PIL dt-binding: remoteproc: Introduce ADSP loader binding remoteproc: qcom_wcnss: Fix circular module dependency remoteproc: Merge table_ptr and cached_table pointers remoteproc: Remove custom vdev handler list remoteproc: Update max_notifyid as we allocate vrings remoteproc: Decouple vdev resources and devices ...

Pull pinctrl updates from Linus Walleij: "Bulk pin control changes for the v4.10 kernel cycle: No core changes this time. Mainly gradual improvement and feature growth in the drivers. New drivers: - New driver for TI DA850/OMAP-L138/AM18XX pinconf - The SX150x was moved over from the GPIO subsystem and reimagined as a pin control driver with GPIO support in a joint effort by three independent users of this hardware. The result was amazingly good! - New subdriver for the Oxnas OX820 Improvements: - The sunxi driver now supports the generic pin control bindings rather than the sunxi-specific.

Pull GPIO updates from Luinus Walleij: "Bulk GPIO changes for the v4.10 kernel cycle: Core changes: - Simplify threaded interrupt handling: instead of passing numbed parameters to gpiochip_irqchip_add_chained() we create a new call: gpiochip_irqchip_add_nested() so the two types are clearly semantically different. Also make sure that all nested chips call gpiochip_set_nested_irqchip() which is necessary for IRQ resend to work properly if it happens. - Return error on seek operations for the chardev. - Clamp values set as part of gpio[d]_direction_output() so that anything != 0 will be send down to the driver as "1" not the value passed in. - ACPI can now support naming of GPIO lines, hogs and holes in the GPIO lists.

We have observed page allocations failures of order 4 during core dump while trying to allocate vma_filesz. This results in a useless core file of size 0. To improve reliability use vmalloc(). Note that the vmalloc() allocation is bounded by sysctl_max_map_count, which is 65,530 by default. So with a 4k page size, and 8 bytes per seg, this is a max of 128 pages or an order 7 allocation. Other parts of the core dump path, such as fill_files_note() are already using vmalloc() for presumably similar reasons.

Add a configuration option to set the default console loglevel. This is, as before, still possible to override at runtime through bootargs (loglevel=<x>), sysrq and /proc/printk. There are cases where adding additional arguments on the commandline is impractical, and changing the default for the kernel when being built makes more sense. Provide such a method here, for those who choose to do so. Also, while touching this code, clarify the difference between MESSAGE_LOGLEVEL_DEFAULT and CONSOLE_LOGLEVEL_DEFAULT.

Commit 4bcc595c ("printk: reinstate KERN_CONT for printing continuation lines") allows to define more message headers for a single message. The motivation is that continuous lines might get mixed. Therefore it make sense to define the right log level for every piece of a cont line. This patch allows to copy only the real message level. We should ignore KERN_CONT because <filename:line> is added for each message. By other words, we want to know where each piece of the line comes from.

Therefore it make sense to define the right log level for every piece of a cont line. The current btrfs_printk() macros do not support continuous lines at the moment. But better be prepared for a custom messages and avoid potential "lvl" buffer overflow. This patch iterates over the entire message header. It is interested only into the message level like the original code. This patch also introduces PRINTK_MAX_SINGLE_HEADER_LEN. Three bytes are enough for the message level header at the moment. But it used to be three, see the commit 04d2c8c8 ("printk: convert the format for KERN_<LEVEL> to a 2 byte pattern"). Also I fixed the default ratelimit level. It looked very strange when it was different from the default log level.

Therefore it make sense to define the right log level for every piece of a cont line. This patch introduces printk_skip_headers() that will skip all headers and uses it in the kdb code instead of printk_skip_level(). This approach helps to fix other printk_skip_level() users independently. Link: http://lkml.kernel.org/r/1478695291-12169-3-git-send-email-pmladek@suse.comSigned-off-by:

Commit 4bcc595c ("printk: reinstate KERN_CONT for printing continuation lines") added back KERN_CONT message header. As a result it might appear in the middle of the line when the parts are squashed via the temporary NMI buffer. A reasonable solution seems to be to split the text in the NNI temporary not only by newlines but also by the message headers. Another solution would be to filter out KERN_CONT when writing to the temporary buffer. But this would complicate the lockless handling. Also it would not solve problems with a missing newline that was there even before the KERN_CONT stuff. This patch moves the temporary buffer handling into separate function. I played with it and it seems that using the char pointers make the code easier to read. Also it prints the final newline as a continuous line. Finally, it moves handling of the s->len overflow into the paranoid check. And allows to recover from the disaster.

vsnprintf() adds the trailing '\0' but it does not count it into the number of printed characters. The result is that there is one byte less space for the real characters in the buffer. The broken check for the free space might cause that we will repeatedly try to print 1 character into the buffer, never reach the full buffer, and do not count the messages as missed. Also vsnprintf() returns the number of characters that would be printed if the buffer was big enough. As a result, s->len might be bigger than the size of the buffer[*]. And the printk() function might return bigger len than it really printed. Both problems are fixed by using vscnprintf() instead. Note that I though about increasing the number of missed messages even when the message was shrunken. But it made the code even more complicated. I think that it is not worth it. Shrunken messages are usually easy to recognize. And it should be a corner case. [*] The overflown s->len value is crazy and unexpected. I "made a mistake" and reported this situation as an internal error when fixed handling of PR_CONT headers in some other patch.
