2019-12-04linux/build_bug.h: change type to intRikard Falkeborn
Having BUILD_BUG_ON_ZERO produce a value of type size_t leads to awkward casts in cases where the result needs to be signed, or of smaller type than size_t. To avoid this, cast the value to int instead and rely on implicit type conversions when a larger or unsigned type is needed.

2019-12-04include/linux/sysctl.h: inline braces for ctl_table and ctl_table_headerAlessio Balsini
Fix coding style of "struct ctl_table" and "struct ctl_table_header" to have inline braces. Besides the wide use of this proposed cose style, this change helps to find at a glance the struct definition when navigating the code.

2019-12-04mm/vmstat: add helpers to get vmstat item names for each enum typeKonstantin Khlebnikov
Statistics in vmstat is combined from counters with different structure, but names for them are merged into one array. This patch adds trivial helpers to get name for each item: const char *zone_stat_name(enum zone_stat_item item); const char *numa_stat_name(enum numa_stat_item item); const char *node_stat_name(enum node_stat_item item); const char *writeback_stat_name(enum writeback_stat_item item); const char *vm_event_name(enum vm_event_item item); Names for enum writeback_stat_item are folded in the middle of vmstat_text so this patch moves declaration into header to calculate offset of following items. Also this patch reuses piece of node stat names for lru list names: const char *lru_list_name(enum lru_list lru); This returns common lru list names: "inactive_anon", "active_anon", "inactive_file", "active_file", "unevictable".

2019-12-04net: Fixed updating of ethertype in skb_mpls_push()Martin Varghese
The skb_mpls_push was not updating ethertype of an ethernet packet if the packet was originally received from a non ARPHRD_ETHER device. In the below OVS data path flow, since the device corresponding to port 7 is an l3 device (ARPHRD_NONE) the skb_mpls_push function does not update the ethertype of the packet even though the previous push_eth action had added an ethernet header to the packet. recirc_id(0),in_port(7),eth_type(0x0800),ipv4(tos=0/0xfc,ttl=64,frag=no), actions:push_eth(src=00:00:00:00:00:00,dst=00:00:00:00:00:00), push_mpls(label=13,tc=0,ttl=64,bos=1,eth_type=0x8847),4 Fixes: 8822e270d697 ("net: core: move push MPLS functionality from OvS to core helper") Signed-off-by: Martin Varghese <martin.varghese@nokia.com> Signed-off-by: David S.

2019-12-03block: don't handle bio based drivers in blk_revalidate_disk_zonesChristoph Hellwig
bio based drivers only need to update q->nr_zones.

Pull XFS updates from Darrick Wong: "For this release, we changed quite a few things. Highlights: - Fixed some long tail latency problems in the block allocator - Removed some long deprecated (and for the past several years no-op) mount options and ioctls - Strengthened the extended attribute and directory verifiers - Audited and fixed all the places where we could return EFSCORRUPTED without logging anything - Refactored the old SGI space allocation ioctls to make the equivalent fallocate calls - Fixed a race between fallocate and directio - Fixed an integer overflow when files have more than a few billion(!) extents - Fixed a longstanding bug where quota accounting could be incorrect when performing unwritten extent conversion on a freshly mounted fs - Fixed various complaints in scrub about soft lockups and unresponsiveness to signals - De-vtable'd the directory handling code, which should make it faster - Converted to the new mount api, for better or for worse - Cleaned up some memory leaks and quite a lot of other smaller fixes and cleanups. A more detailed summary: - Fill out the build string - Prevent inode fork extent count overflows - Refactor the allocator to reduce long tail latency - Rework incore log locking a little to reduce spinning - Break up the xfs_iomap_begin functions into smaller more cohesive parts - Fix allocation alignment being dropped too early when the allocation request is for more blocks than an AG is large - Other small cleanups - Clean up file buftarg retrieval helpers - Hoist the resvsp and unresvsp ioctls to the vfs - Remove the undocumented biosize mount option, since it has never been mentioned as existing or supported on linux - Clean up some of the mount option printing and parsing - Enhance attr leaf verifier to check block structure - Check dirent and attr names for invalid characters before passing them to the vfs - Refactor open-coded bmbt walking - Fix a few places where we return EIO instead of EFSCORRUPTED after failing metadata sanity checks - Fix a synchronization problem between fallocate and aio dio corrupting the file length - Clean up various loose ends in the iomap and bmap code - Convert to the new mount api - Make sure we always log something when returning EFSCORRUPTED - Fix some problems where long running scrub loops could trigger soft lockup warnings and/or fail to exit due to fatal signals pending - Fix various Coverity complaints - Remove most of the function pointers from the directory code to reduce indirection penalties - Ensure that dquots are attached to the inode when performing unwritten extent conversion after io - Deuglify incore projid and crtime types - Fix another AGI/AGF locking order deadlock when renaming - Clean up some quota typedefs - Remove the FSSETDM ioctls which haven't done anything in 20 years - Fix some memory leaks when mounting the log fails - Fix an underflow when updating an xattr leaf freemap - Remove some trivial wrappers - Report metadata corruption as an error, not a (potentially) fatal assertion - Clean up the dir/attr buffer mapping code - Allow fatal signals to kill scrub during parent pointer checks" * tag 'xfs-5.5-merge-16' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (198 commits) xfs: allow parent directory scans to be interrupted with fatal signals xfs: remove the mappedbno argument to xfs_da_get_buf xfs: remove the mappedbno argument to xfs_da_read_buf xfs: split xfs_da3_node_read xfs: remove the mappedbno argument to xfs_dir3_leafn_read xfs: remove the mappedbno argument to xfs_dir3_leaf_read xfs: remove the mappedbno argument to xfs_attr3_leaf_read xfs: remove the mappedbno argument to xfs_da_reada_buf xfs: improve the xfs_dabuf_map calling conventions xfs: refactor xfs_dabuf_map xfs: simplify mappedbno handling in xfs_da_{get,read}_buf xfs: report corruption only as a regular error xfs: Remove kmem_zone_free() wrapper xfs: Remove kmem_zone_destroy() wrapper xfs: Remove slab init wrappers xfs: fix attr leaf header freemap.size underflow xfs: fix some memory leaks in log recovery xfs: fix another missing include xfs: remove XFS_IOC_FSSETDM and XFS_IOC_FSSETDM_BY_HANDLE xfs: remove duplicated include from xfs_dir2_data.c ...

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.5 kernel cycle Core changes: - Expose pull up/down flags for the GPIO character device to userspace. After clear input from the RaspberryPi and Beagle communities, it has been established that prototyping, industrial automation and make communities strongly need this feature, and as we want people to use the character device, we have implemented the simple pull up/down interface for GPIO lines. This means we can specify that a (chip-specific) pull up/down resistor can be enabled, but does not offer fine-grained control such as cases where the resistance of the same pull resistor can be controlled (yet). - Introduce devm_fwnode_gpiod_get_index() and start to phase out the old symbol devm_fwnode_get_index_gpiod_from_child(). - A bit of documentation clean-up work. - Introduce a define for GPIO line directions and deploy it in all GPIO drivers in the drivers/gpio directory. - Add a special callback to populate pin ranges when cooperating with the pin control subsystem and registering ranges as part of adding a gpiolib driver and a gpio_irq_chip driver at the same time. This is also deployed in the Intel Merrifield driver. New drivers: - RDA Micro GPIO controller. - XGS-iproc GPIO driver. Driver improvements: - Wake event and debounce support on the Tegra 186 driver. - Finalize the Aspeed SGPIO driver. - MPC8xxx uses a normal IRQ handler rather than a chained handler" * tag 'gpio-v5.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (64 commits) gpio: Add TODO item for regmap helper Documentation: gpio: driver.rst: Fix warnings gpio: of: Fix bogus reference to gpiod_get_count() gpiolib: Grammar s/manager/managed/ gpio: lynxpoint: Setup correct IRQ handlers MAINTAINERS: Replace my email by one @kernel.org gpiolib: acpi: Make acpi_gpiochip_alloc_event always return AE_OK gpio/mpc8xxx: fix qoriq GPIO reading gpio: mpc8xxx: Don't overwrite default irq_set_type callback gpiolib: acpi: Print pin number on acpi_gpiochip_alloc_event errors gpiolib: fix coding style in gpiod_hog() drm/bridge: ti-tfp410: switch to using fwnode_gpiod_get_index() gpio: merrifield: Pass irqchip when adding gpiochip gpio: merrifield: Add GPIO <-> pin mapping ranges via callback gpiolib: Introduce ->add_pin_ranges() callback gpio: mmio: remove untrue leftover comment gpio: em: Use platform_get_irq() to obtain interrupts gpio: tegra186: Add debounce support gpio: tegra186: Program interrupt route mapping gpio: tegra186: Derive register offsets from bank/port ...

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This merge window we have one small clk provider API in the core framework and then a bunch of driver updates and a handful of new drivers. In terms of diffstat the Qualcomm and Amlogic drivers are high up there because of all the clk data introcued by new drivers. The Nvidia Tegra driver had a lot of work done this cycle too to support suspend/resume and memory controllers. And the OMAP clk driver got proper clk and reset handling in place. Rounding out the patches are various updates to remove unused data, mark things static, correct incorrect data in drivers, etc. All the little things that improve drivers and maintain code health. I will point out that there's a patch in here for the GPIO clk driver, that almost nobody uses, which changes behavior and causes clk_set_rate() to try to change the GPIO gate clk's parent. Other than that things are fairly well SoC specific here. Core: - Add a clk provider API to get current parent index - Plug a memory leak in clk_unregister() path New Drivers: - CGU in Ingenix X1000 - Bitmain BM1880 clks - Qualcomm MSM8998 GPU clk controllers - Qualcomm SC7180 GCC and RPMH clk controllers - Qualcomm QCS404 Q6SSTOP clk controllers - Add support for the Renesas R-Car M3-W+ (r8a77961) SoC - Add support for the Renesas RZ/G2N (r8a774b1) SoC - Add Tegra20/30 External Memory Clock (EMC) support Updates: - Make gpio gate clks propagate rate setting up to parent - Prepare Armada 3700 for suspend to RAM by moving PCIe suspend/resume priority - Drop unused variables, enums, etc. in various clk drivers - Convert various drivers to use devm_platform_ioremap_resource() - Use struct_size() some more in various clk drivers - Improve Rockchip px30 clk tree - Add suspend/resume support to Tegra210 clk driver - Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP - Allwinner DT exports and H6 clk tree fixes - Proper clk and reset handling for OMAP SoCs - Revamped TI divider clk to clamp max divider - Make 1443X/1416X PLL clock structure common for reusing among i.MX8 SoCs - Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used - Add VIDEO2_PLL clock for imx8mq - Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs - Add sm1 support in the Amlogic audio clock controller - Switch some clocks on R-Car Gen2/3 to .determine_rate() - Remove Renesas R-Car Gen2 legacy DT clock support - Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3 - Improve Renesas R-Car Gen3 SD clock handling - Add rate table for Samsung exynos542x GPU and VPLL clks - Fix potential CPU performance degradation after system suspend/resume cycle on exynos542x SoCs" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (160 commits) clk: aspeed: Add RMII RCLK gates for both AST2500 MACs MAINTAINERS: Add entry for BM1880 SoC clock driver clk: Add common clock driver for BM1880 SoC dt-bindings: clock: Add devicetree binding for BM1880 SoC clk: Add clk_hw_unregister_composite helper function definition clk: Zero init clk_init_data in helpers clk: ingenic: Allow drivers to be built with COMPILE_TEST MAINTAINERS: Update section for Ux500 clock drivers clk: mark clk_disable_unused() as __init clk: Fix memory leak in clk_unregister() clk: Ingenic: Add CGU driver for X1000. dt-bindings: clock: Add X1000 bindings. clk: tegra: Use match_string() helper to simplify the code clk: pxa: fix one of the pxa RTC clocks clk: sprd: Use IS_ERR() to validate the return value of syscon_regmap_lookup_by_phandle() clk: armada-xp: remove unused code clk: tegra: Fix build error without CONFIG_PM_SLEEP clk: tegra: Add missing stubs for the case of !CONFIG_PM_SLEEP clk: tegra: Optimize PLLX restore on Tegra20/30 clk: tegra: Add suspend and resume support on Tegra210 ...
