2016-12-14mm: use vmf->address instead of of vmf->virtual_addressJan Kara2-7/+5
Every single user of vmf->virtual_address typed that entry to unsigned long before doing anything with it so the type of virtual_address does not really provide us any additional safety. Just use masked vmf->address which already has the appropriate type.

2016-12-14sparc: implement watchdog_nmi_enable and watchdog_nmi_disableBabu Moger1-1/+43
Implement functions watchdog_nmi_enable and watchdog_nmi_disable to enable/disable nmi watchdog. Sparc uses arch specific nmi watchdog handler. Currently, we do not have a way to enable/disable nmi watchdog dynamically. With these patches we can enable or disable arch specific nmi watchdogs using proc or sysctl interface. Example commands. To enable: echo 1 > /proc/sys/kernel/nmi_watchdog To disable: echo 0 > /proc/sys/kernel/nmi_watchdog It can also achieved using the sysctl parameter kernel.nmi_watchdog Link: http://lkml.kernel.org/r/1478034826-43888-4-git-send-email-babu.moger@oracle.com Signed-off-by: Babu Moger <babu.moger@oracle.com> Acked-by: Don Zickus <dzickus@redhat.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Jiri Kosina <jkosina@suse.cz> Cc: Andi Kleen <andi@firstfloor.org> Cc: Yaowei Bai <baiyaowei@cmss.chinamobile.com> Cc: Aaron Tomlin <atomlin@redhat.com> Cc: Ulrich Obergfell <uobergfe@redhat.com> Cc: Tejun Heo <tj@kernel.org> Cc: Hidehiro Kawai <hidehiro.kawai.ez@hitachi.com> Cc: Josh Hunt <johunt@akamai.com> Cc: "David S.

2016-12-14arch/arc: add option to skip sync on DMA mappingAlexander Duyck1-1/+4
Patch series "Add support for DMA writable pages being writable by the network stack", v3. The first 19 patches in the set add support for the DMA attribute DMA_ATTR_SKIP_CPU_SYNC on multiple platforms/architectures. This is needed so that we can flag the calls to dma_map/unmap_page so that we do not invalidate cache lines that do not currently belong to the device. Instead we have to take care of this in the driver via a call to sync_single_range_for_cpu prior to freeing the Rx page. Patch 20 adds support for dma_map_page_attrs and dma_unmap_page_attrs so that we can unmap and map a page using the DMA_ATTR_SKIP_CPU_SYNC attribute. Patch 21 adds support for freeing a page that has multiple references being held by a single caller. This way we can free page fragments that were allocated by a given driver. The last 2 patches use these updates in the igb driver, and lay the groundwork to allow for us to reimplement the use of build_skb. This patch (of 23): This change allows us to pass DMA_ATTR_SKIP_CPU_SYNC which allows us to avoid invoking cache line invalidation if the driver will just handle it later via a sync_for_cpu or sync_for_device call.

2016-12-14kexec: export the value of phys_base instead of symbol addressBaoquan He1-1/+2
Currently in x86_64, the symbol address of phys_base is exported to vmcoreinfo. Dave Anderson complained this is really useless for his Crash implementation. Because in user-space utility Crash and Makedumpfile which exported vmcore information is mainly used for, value of phys_base is needed to covert virtual address of exported kernel symbol to physical address. Especially init_level4_pgt, if we want to access and go over the page table to look up a PA corresponding to VA, firstly we need calculate page_dir = SYMBOL(init_level4_pgt) - __START_KERNEL_map + phys_base; Now in Crash and Makedumpfile, we have to analyze the vmcore elf program header to get value of phys_base. As Dave said, it would be preferable if it were readily availabl in vmcoreinfo rather than depending upon the PT_LOAD semantics. Hence in this patch change to export the value of phys_base instead of its virtual address. And people also complained that KERNEL_IMAGE_SIZE exporting is x86_64 only, should be moved into arch dependent function arch_crash_save_vmcoreinfo. Do the moving in this patch.

2016-12-14Revert "kdump, vmcoreinfo: report memory sections virtual addresses"Baoquan He1-3/+0
This reverts commit 0549a3c02efb ("kdump, vmcoreinfo: report memory sections virtual addresses"). Commit 0549a3c02efb tells the userspace utility makedumpfile the randomized base address of these memmory sections when mm kaslr is enabled. However the following patch "kexec: export the value of phys_base instead of symbol address" makes makedumpfile not need these addresses any more. Besides we should use VMCOREINFO_NUMBER to export the value of the variable so that we can use the existing number_table mechanism of Makedumpfile to fetch it. So revert it now. If needed we can add it later. http://lists.infradead.org/pipermail/kexec/2016-October/017540.html Link: http://lkml.kernel.org/r/1478568596-30060-1-git-send-email-bhe@redhat.com Signed-off-by: Baoquan He <bhe@redhat.com> Cc: Thomas Garnier <thgarnie@google.com> Cc: Baoquan He <bhe@redhat.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: "H .

Pull block layer updates from Jens Axboe: "This is the main block pull request this series. Contrary to previous release, I've kept the core and driver changes in the same branch. We always ended up having dependencies between the two for obvious reasons, so makes more sense to keep them together. That said, I'll probably try and keep more topical branches going forward, especially for cycles that end up being as busy as this one. The major parts of this pull request is: - Improved support for O_DIRECT on block devices, with a small private implementation instead of using the pig that is fs/direct-io.c. From Christoph. - Request completion tracking in a scalable fashion. This is utilized by two components in this pull, the new hybrid polling and the writeback queue throttling code. - Improved support for polling with O_DIRECT, adding a hybrid mode that combines pure polling with an initial sleep. From me. - Support for automatic throttling of writeback queues on the block side. This uses feedback from the device completion latencies to scale the queue on the block side up or down. From me. - Support from SMR drives in the block layer and for SD. From Hannes and Shaun. - Multi-connection support for nbd. From Josef. - Cleanup of request and bio flags, so we have a clear split between which are bio (or rq) private, and which ones are shared.

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 ...

Independent of whether the vma is for anonymous memory, some arches like ppc64 would like to override pmd_move_must_withdraw(). One option is to encapsulate the vma_is_anonymous() check for general architectures inside pmd_move_must_withdraw() so that is always called and architectures that need unconditional overriding can override this function. ppc64 needs to override the function when the MMU is configured to use hash PTE's.
