Just like commit f67676d1 for read/write requests, this one ensures that the msghdr data is fully copied if we need to punt a recvmsg or sendmsg system call to async context. Signed-off-by: NJens Axboe <axboe@kernel.dk>

Currently we don't copy the iovecs when we punt to async context. This can be problematic for applications that store the iovec on the stack, as they often assume that it's safe to let the iovec go out of scope as soon as IO submission has been called. This isn't always safe, as we will re-copy the iovec once we're in async context. Make this 100% safe by copying the iovec just once. With this change, applications may safely store the iovec on the stack for all cases. Reported-by: N李通洲 <carter.li@eoitek.com> Signed-off-by: NJens Axboe <axboe@kernel.dk>

Right now we just copy the sqe for async offload, but we want to store more context across an async punt. In preparation for doing so, put the sqe copy inside a structure that we can expand. With this pointer added, we can get rid of REQ_F_FREE_SQE, as that is now indicated by whether req->io is NULL or not. No functional changes in this patch.

Commit 6917d068 ("block: merge invalidate_partitions into rescan_partitions") caused a regression where systemd-udevd spins forever using max CPU starting at boot time. It's caused by a behavior change where a KOBJ_CHANGE uevent is now sent in a case where previously it wasn't. Restore the old behavior.

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.

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 ...

After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers.

Pull sysctl system call removal from Eric Biederman: "As far as I can tell we have reached the point where no one enables the sysctl system call anymore. It still is enabled in a few defconfigs but they are mostly the rarely used one and in asking people about that it was more cut & paste enabled than anything else. This is single commit that just deletes code. Leaving just enough code so that the deprecated sysctl warning continues to be printed. If my analysis turns out to be wrong and someone actually cares it will be easy to revert this commit and have the system call again. There was one new xtensa defconfig in linux-next that enabled the system call this cycle and when asked about it the maintainer of the code replied that it was not enabled on purpose. As of today's linux-next tree that defconfig no longer enables the system call. What we saw in the review discussion was that if we go a step farther than my patch and mess with uapi headers there are pieces of code that won't compile, but nothing minds the system call actually disappearing from the kernel" Link: https://lore.kernel.org/lkml/201910011140.EA0181F13@keescook/ * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: sysctl: Remove the sysctl system call

Pull RAS fix from Borislav Petkov: "One urgent fix for the thermal throttling machinery: the recent change reworking the thermal notifications forgot to mask out read-only and reserved bits in the thermal status MSRs, leading to exceptions while writing those MSRs. The fix takes care of masking out those bits first" * 'ras-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mce/therm_throt: Mask out read-only and reserved MSR bits

Pull powerpc updates from Michael Ellerman: "Highlights: - Infrastructure for secure boot on some bare metal Power9 machines. The firmware support is still in development, so the code here won't actually activate secure boot on any existing systems. - A change to xmon (our crash handler / pseudo-debugger) to restrict it to read-only mode when the kernel is lockdown'ed, otherwise it's trivial to drop into xmon and modify kernel data, such as the lockdown state. - Support for KASLR on 32-bit BookE machines (Freescale / NXP). - Fixes for our flush_icache_range() and __kernel_sync_dicache() (VDSO) to work with memory ranges >4GB. - Some reworks of the pseries CMM (Cooperative Memory Management) driver to make it behave more like other balloon drivers and enable some cleanups of generic mm code. - A series of fixes to our hardware breakpoint support to properly handle unaligned watchpoint addresses. Plus a bunch of other smaller improvements, fixes and cleanups.
