Pull remoteproc updates from Bjorn Andersson: "In the remoteproc core, it's now possible to mark the sysfs attributes read only on a per-instance basis, which is then used by the TI wkup M3 driver. Also, the rproc_shutdown() interface propagates errors to the caller and an array underflow is fixed in the debugfs interface. The rproc_da_to_va() API is moved to the public API to allow e.g. child rpmsg devices to acquire pointers to memory shared with the remote processor. The TI K3 R5F and DSP drivers gains support for attaching to instances already started by the bootloader, aka IPC-only mode. The Mediatek remoteproc driver gains support for the MT8186 SCP. The driver's probe function is reordered and moved to use the devres version of rproc_alloc() to save a few gotos. The driver's probe function is also transitioned to use dev_err_probe() to provide better debug support. Support for the Qualcomm SC7280 Wireless Subsystem (WPSS) is introduced. The Hexagon based remoteproc drivers gains support for voting for interconnect bandwidth during launch of the remote processor. The modem subsystem (MSS) driver gains support for probing the BAM-DMUX driver, which provides the network interface towards the modem on a set of older Qualcomm platforms. In addition a number a bug fixes are introduces in the Qualcomm drivers. Lastly Qualcomm ADSP DeviceTree binding is converted to YAML format, to allow validation of DeviceTree source files" * tag 'rproc-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (22 commits) remoteproc: qcom_q6v5_mss: Create platform device for BAM-DMUX remoteproc: qcom: q6v5_wpss: Add support for sc7280 WPSS dt-bindings: remoteproc: qcom: Add SC7280 WPSS support dt-bindings: remoteproc: qcom: adsp: Convert binding to YAML remoteproc: k3-dsp: Add support for IPC-only mode for all K3 DSPs remoteproc: k3-dsp: Refactor mbox request code in start remoteproc: k3-r5: Add support for IPC-only mode for all R5Fs remoteproc: k3-r5: Refactor mbox request code in start remoteproc: Change rproc_shutdown() to return a status remoteproc: qcom: q6v5: Add interconnect path proxy vote remoteproc: mediatek: Support mt8186 scp dt-bindings: remoteproc: mediatek: Add binding for mt8186 scp remoteproc: qcom_q6v5_mss: Fix some leaks in q6v5_alloc_memory_region remoteproc: qcom_wcnss: Add missing of_node_put() in wcnss_alloc_memory_region remoteproc: qcom: Fix missing of_node_put in adsp_alloc_memory_region remoteproc: move rproc_da_to_va declaration to remoteproc.h remoteproc: wkup_m3: Set sysfs_read_only flag remoteproc: Introduce sysfs_read_only flag remoteproc: Fix count check in rproc_coredump_write() remoteproc: mtk_scp: Use dev_err_probe() where possible ...

Pull rpmsg updates from Bjorn Andersson: "The major part of the rpmsg changes for v5.18 relates to improvements in the rpmsg char driver, which now allow automatically attaching to rpmsg channels as well as initiating new communication channels from the Linux side. The SMD driver is moved to arch_initcall with the purpose of registering root clocks earlier during boot. Also in the SMD driver, a workaround for the resource power management (RPM) channel is introduced to resolve an issue where both the RPM and Linux side waits for the other to close the communication established by the bootloader - this unblocks support for clocks and regulators on some older Qualcomm platforms" * tag 'rpmsg-v5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: rpmsg: ctrl: Introduce new RPMSG_CREATE/RELEASE_DEV_IOCTL controls rpmsg: char: Introduce the "rpmsg-raw" channel rpmsg: char: Add possibility to use default endpoint of the rpmsg device rpmsg: char: Refactor rpmsg_chrdev_eptdev_create function rpmsg: Update rpmsg_chrdev_register_device function rpmsg: Move the rpmsg control device from rpmsg_char to rpmsg_ctrl rpmsg: Create the rpmsg class in core instead of in rpmsg char rpmsg: char: Export eptdev create and destroy functions rpmsg: char: treat rpmsg_trysend() ENOMEM as EAGAIN rpmsg: qcom_smd: Fix redundant channel->registered assignment rpmsg: use struct_size over open coded arithmetic rpmsg: smd: allow opening rpm_requests even if already opened rpmsg: qcom_smd: Promote to arch_initcall

Pull clk updates from Stephen Boyd: "There's one large change in the core clk framework here. We change how clk_set_rate_range() works so that the frequency is re-evaulated each time the rate is changed. Previously we wouldn't let clk providers see a rate that was different if it was still within the range, which could be bad for power if the clk could run slower when a range expands. Now the clk provider can decide to do something differently when the constraints change. This broke Nvidia's clk driver so we had to wait for the fix for that to bake a little more in -next. The rate range patch series also introduced a kunit suite for the clk framework that we're going to extend in the next release. It already made it easy to find corner cases in the rate range patches so I'm excited to see it cover more clk code and increase our confidence in core framework patches in the future. I also added a kunit test for the basic clk gate code and that work will continue to cover more basic clk types: muxes, dividers, etc. Beyond the core code we have the usual set of clk driver updates and additions. Qualcomm again dominates the diffstat here with lots more SoCs being supported and i.MX follows afer that with a similar number of SoCs gaining clk drivers. Beyond those large additions there's drivers being modernized to use clk_parent_data so we can move away from global string names for all the clks in an SoC. Finally there's lots of little fixes all over the clk drivers for typos, warnings, and missing clks that aren't critical and get batched up waiting for the next merge window to open. Nothing super big stands out in the driver pile. Full details are below. Core: - Make clk_set_rate_range() re-evaluate the limits each time - Introduce various clk_set_rate_range() tests - Add clk_drop_range() to drop a previously set range New Drivers: - i.MXRT1050 clock driver and bindings - i.MX8DXL clock driver and bindings - i.MX93 clock driver and bindings - NCO blocks on Apple SoCs - Audio clks on StarFive JH7100 RISC-V SoC - Add support for the new Renesas RZ/V2L SoC - Qualcomm SDX65 A7 PLL - Qualcomm SM6350 GPU clks - Qualcomm SM6125, SM6350, QCS2290 display clks - Qualcomm MSM8226 multimedia clks Updates: - Kunit tests for clk-gate implementation - Terminate arrays with sentinels and make that clearer - Cleanup SPDX tags - Fix typos in comments - Mark mux table as const in clk-mux - Make the all_lists array const - Convert Cirrus Logic CS2000P driver to regmap, yamlify DT binding and add support for dynamic mode - Clock configuration on Microchip PolarFire SoCs - Free allocations on probe error in Mediatek clk driver - Modernize Mediatek clk driver by consolidating code - Add watchdog (WDT), I2C, and pin function controller (PFC) clocks on Renesas R-Car S4-8 - Improve the clocks for the Rockchip rk3568 display outputs (parenting, pll-rates) - Use of_device_get_match_data() instead of open-coding on Rockchip rk3568 - Reintroduce the expected fractional-divider behaviour that disappeared with the addition of CLK_FRAC_DIVIDER_POWER_OF_TWO_PS - Remove SYS PLL 1/2 clock gates for i.MX8M* - Remove AUDIO MCLK ROOT from i.MX7D - Add fracn gppll clock type used by i.MX93 - Add new composite clock for i.MX93 - Add missing media mipi phy ref clock for i.MX8MP - Fix off by one in imx_lpcg_parse_clks_from_dt() - Rework for the imx pll14xx - sama7g5: One low priority fix for GCLK of PDMC - Add DMA engine (SYS-DMAC) clocks on Renesas R-Car S4-8 - Add MOST (MediaLB I/F) clocks on Renesas R-Car E3 and D3 - Add CAN-FD clocks on Renesas R-Car V3U - Qualcomm SC8280XP RPMCC - Add some missing clks on Qualcomm MSM8992/MSM8994/MSM8998 SoCs - Rework Qualcomm GCC bindings and convert SDM845 camera bindig to YAML - Convert various Qualcomm drivers to use clk_parent_data - Remove test clocks from various Qualcomm drivers - Crypto engine clks on Qualcomm IPQ806x + more freqs for SDCC/NSS - Qualcomm SM8150 EMAC, PCIe, UFS GDSCs - Better pixel clk frequency support on Qualcomm RCG2 clks" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (227 commits) clk: zynq: Update the parameters to zynq_clk_register_periph_clk clk: zynq: trivial warning fix clk: Drop the rate range on clk_put() clk: test: Test clk_set_rate_range on orphan mux clk: Initialize orphan req_rate dt-bindings: clock: drop useless consumer example dt-bindings: clock: renesas: Make example 'clocks' parsable clk: qcom: gcc-msm8994: Fix gpll4 width dt-bindings: clock: fix dt_binding_check error for qcom,gcc-other.yaml clk: rs9: Add Renesas 9-series PCIe clock generator driver clk: fixed-factor: Introduce devm_clk_hw_register_fixed_factor_index() clk: visconti: prevent array overflow in visconti_clk_register_gates() dt-bindings: clk: rs9: Add Renesas 9-series I2C PCIe clock generator clk: sifive: Move all stuff into SoCs header files from C files clk: sifive: Add SoCs prefix in each SoCs-dependent data riscv: dts: Change the macro name of prci in each device node dt-bindings: change the macro name of prci in header files and example clk: sifive: duplicate the macro definitions for the time being clk: qcom: sm6125-gcc: fix typos in comments clk: ti: clkctrl: fix typos in comments ...

Jason Donenfeld reports that my commit 1c24a186 ("fs: fd tables have to be multiples of BITS_PER_LONG") doesn't work, and the reason is an embarrassing brown-paper-bag bug. Yes, we want to align the number of fds to BITS_PER_LONG, and yes, the reason they might not be aligned is because the incoming 'max_fd' argument might not be aligned. But aligining the argument - while simple - will cause a "infinitely big" maxfd (eg NR_OPEN_MAX) to just overflow to zero. Which most definitely isn't what we want either. The obvious fix was always just to do the alignment last, but I had moved it earlier just to make the patch smaller and the code look simpler. Duh. It certainly made _me_ look simple.

This has always been the rule: fdtables have several bitmaps in them, and as a result they have to be sized properly for bitmaps. We walk those bitmaps in chunks of 'unsigned long' in serveral cases, but even when we don't, we use the regular kernel bitops that are defined to work on arrays of 'unsigned long', not on some byte array. Now, the distinction between arrays of bytes and 'unsigned long' normally only really ends up being noticeable on big-endian systems, but Fedor Pchelkin and Alexey Khoroshilov reported that copy_fd_bitmaps() could be called with an argument that wasn't even a multiple of BITS_PER_BYTE. And then it fails to do the proper copy even on little-endian machines. The bug wasn't in copy_fd_bitmap(), but in sane_fdtable_size(), which didn't actually sanitize the fdtable size sufficiently, and never made sure it had the proper BITS_PER_LONG alignment. That's partly because the alignment historically came not from having to explicitly align things, but simply from previous fdtable sizes, and from count_open_files(), which counts the file descriptors by walking them one 'unsigned long' word at a time and thus naturally ends up doing sizing in the proper 'chunks of unsigned long'. But with the introduction of close_range(), we now have an external source of "this is how many files we want to have", and so sane_fdtable_size() needs to do a better job. This also adds that explicit alignment to alloc_fdtable(), although there it is mainly just for documentation at a source code level. The arithmetic we do there to pick a reasonable fdtable size already aligns the result sufficiently. In fact,clang notices that the added ALIGN() in that function doesn't actually do anything, and does not generate any extra code for it. It turns out that gcc ends up confusing itself by combining a previous constant-sized shift operation with the variable-sized shift operations in roundup_pow_of_two(). And probably due to that doesn't notice that the ALIGN() is a no-op. But that's a (tiny) gcc misfeature that doesn't matter. Having the explicit alignment makes sense, and would actually matter on a 128-bit architecture if we ever go there. This also adds big comments above both functions about how fdtable sizes have to have that BITS_PER_LONG alignment.

Freescale Layerscape Lynx 28G SerDes PHYs are only present on Freescale/NXP Layerscape SoCs. Move PHY_FSL_LYNX_28G outside the block for ARCH_MXC, as the latter is meant for i.MX8 SoCs, which is a different family than Layerscape. Add a dependency on ARCH_LAYERSCAPE, to prevent asking the user about this driver when configuring a kernel without Layerscape SoC support.

'dma-ranges' in the example is written for cell sizes of 2 cells, but the schema and example specify sizes of 1 cell. As the h/w has a bus address of >32-bits, cell sizes of 2 is correct. Update the schema's '#address-cells' and '#size-cells' to be 2 and adjust the example throughout. There's no error currently because dtc only checks 'dma-ranges' is a correct multiple number of cells (3) and the schema checking is based on bracketing of entries.

The current autocork algorithms will delay the data transmission in BH context to smc_release_cb() when sock_lock is hold by user. So there is a possibility that when connection is being actively closed (sock_lock is hold by user now), some corked data still remains in sndbuf, waiting to be sent by smc_release_cb(). This will cause: - smc_close_stream_wait(), which is called under the sock_lock, has a high probability of timeout because data transmission is delayed until sock_lock is released. - Unexpected data sends may happen after connction closed and use the rtoken which has been deleted by remote peer through LLC_DELETE_RKEY messages. So this patch will try to send out the remaining corked data in sndbuf before active close process, to ensure data integrity and avoid unexpected data transmission after close.
