Pull clk subsystem updates from Stephen Boyd: "We have a fairly balanced mix of clk driver updates and clk framework updates this time around. It's the usual pile of new drivers for new hardware out there and the normal small fixes and updates, but then we have some core framework changes too. In the core framework, we introduce support for a clk_get_optional() API to get clks that may not always be populated and a way to devm manage clkdev lookups registered by provider drivers. We also do some refactoring to simplify the interface between clkdev and the common clk framework so we can reuse the DT parsing and clk_get() path in provider drivers in the future. This work will continue in the next few cycles while we convert how providers specify clk parents. On the driver side, the biggest part of the dirstat is the Amlogic clk driver that got support for the G12A SoC. It dominates with almost half the overall diff, while the second largest part of the diff is in the i.MX clk driver that gained support for imx8mm SoCs. After that, we have the Actions Semiconductor and Qualcomm drivers rounding out the big part of the dirstat because they both got new hardware support for SoCs. The rest is just various updates and non-critical fixes for existing drivers. Core: - Convert a few clk bindings to JSON schema format - Add a {devm_}clk_get_optional() API - Add devm_clk_hw_register_clkdev() API to manage clkdev lookups - Start rewriting clk parent registration and supporting device links by moving around code that supports clk_get() and DT parsing of the 'clocks' property New Drivers: - Add Qualcomm MSM8998 RPM managed clks - IPA clk support on Qualcomm RPMh clk controllers - Actions Semi S500 SoC clk support - Support for fixed rate clks populated from an MMIO register - Add RPC (QSPI/HyperFLASH) clocks on Renesas R-Car V3H - Add TMU (timer) clocks on Renesas RZ/G2E - Add Amlogic G12A Always-On Clock Controller - Add 32k clock generation for Amlogic AXG - Add support for the Mali GPU clocks on Amlogic Meson8 - Add Amlogic G12A EE clock controller driver - Add missing CANFD clocks on Renesas RZ/G2M and RZ/G2E - Add i.MX8MM SoC clk driver support Removed Drivers: - Remove clps711x driver as the board support is gone Updates: - 3rd ECO fix for Mediatek MT2712 SoCs - Updates for Qualcomm MSM8998 GCC clks - Random static analysis fixes for clk drivers - Support for sleeping gpios in the clk-gpio type - Minor fixes for STM32MP1 clk driver (parents, critical flag, etc.) - Split LCDC into two clks on the Marvell MMP2 SoC - Various DT of_node refcount fixes - Get rid of CLK_IS_BASIC from TI code (yay!) - TI Autoidle clk support - Fix Amlogic Meson8 APB clock ID name - Claim input clocks through DT for Amlogic AXG and GXBB - Correct the DU (display unit) parent clock on Renesas RZ/G2E - Exynos5433 IMEM CMU crypto clk support (SlimSS) - Fix for the PLL-MIPI on the Allwinner A23 - Fix Rockchip rk3328 PLL rate calculation - Add SET_RATE_PARENT flag on display clk of Rockhip rk3066 - i.MX SCU clk driver clk_set_parent() and cpufreq support" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (150 commits) dt-bindings: clock: imx8mq: Fix numbering overlaps and gaps clk: ti: clkctrl: Fix clkdm_name regression for TI_CLK_CLKCTRL_COMPAT clk: fixup default index for of_clk_get_by_name() clk: Move of_clk_*() APIs into clk.c from clkdev.c clk: Inform the core about consumer devices clk: Introduce of_clk_get_hw_from_clkspec() clk: core: clarify the check for runtime PM clk: Combine __clk_get() and __clk_create_clk() clk: imx8mq: add GPIO clocks to clock tree clk: mediatek: correct cpu clock name for MT8173 SoC clk: imx: Refactor entire sccg pll clk clk: imx: scu: add cpu frequency scaling support clk: mediatek: Mark bus and DRAM related clocks as critical clk: mediatek: Add flags to mtk_gate clk: mediatek: Add MUX_FLAGS macro clk: qcom: gcc-sdm845: Define parent of PCIe PIPE clocks clk: ingenic: Remove set but not used variable 'enable' clk: at91: programmable: remove unneeded register read clk: mediatek: using CLK_MUX_ROUND_CLOSEST for the clock of dpi1_sel clk: mediatek: add MUX_GATE_FLAGS_2 ...

The only detail worth noting, outside the summary below, is that the "libnvdimm-start-pad" topic has been truncated to just cleanups and small fixes.

Pull vfs mount infrastructure updates from Al Viro: "The rest of core infrastructure; no new syscalls in that pile, but the old parts are switched to new infrastructure. At that point conversions of individual filesystems can happen independently; some are done here (afs, cgroup, procfs, etc.), there's also a large series outside of that pile dealing with NFS (quite a bit of option-parsing stuff is getting used there - it's one of the most convoluted filesystems in terms of mount-related logics), but NFS bits are the next cycle fodder. It got seriously simplified since the last cycle; documentation is probably the weakest bit at the moment - I considered dropping the commit introducing Documentation/filesystems/mount_api.txt (cutting the size increase by quarter ;-), but decided that it would be better to fix it up after -rc1 instead. That pile allows to do followup work in independent branches, which should make life much easier for the next cycle. fs/super.c size increase is unpleasant; there's a followup series that allows to shrink it considerably, but I decided to leave that until the next cycle" * 'work.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (41 commits) afs: Use fs_context to pass parameters over automount afs: Add fs_context support vfs: Add some logging to the core users of the fs_context log vfs: Implement logging through fs_context vfs: Provide documentation for new mount API vfs: Remove kern_mount_data() hugetlbfs: Convert to fs_context cpuset: Use fs_context kernfs, sysfs, cgroup, intel_rdt: Support fs_context cgroup: store a reference to cgroup_ns into cgroup_fs_context cgroup1_get_tree(): separate "get cgroup_root to use" into a separate helper cgroup_do_mount(): massage calling conventions cgroup: stash cgroup_root reference into cgroup_fs_context cgroup2: switch to option-by-option parsing cgroup1: switch to option-by-option parsing cgroup: take options parsing into ->parse_monolithic() cgroup: fold cgroup1_mount() into cgroup1_get_tree() cgroup: start switching to fs_context ipc: Convert mqueue fs to fs_context proc: Add fs_context support to procfs ...

Doing this, the IMX8MQ_CLK_CSI2_CORE is not overlapped with IMX8MQ_CLK_GPT1 anymore. IMX8MQ_CLK_GPT1_ROOT changes from 193 to 183 and all the following ids are updated accordingly. Reported-by:

This also makes sctp_stream_alloc_(out|in) saner, in that they no longer allocate new flex_arrays/genradixes, they just preallocate more elements. This code does however have a suspicious lack of locking. Link: http://lkml.kernel.org/r/20181217131929.11727-7-kent.overstreet@gmail.comSigned-off-by:

Very simple radix tree implementation that supports storing arbitrary size entries, up to PAGE_SIZE - upcoming patches will convert existing flex_array users to genradixes. The new genradix code has a much simpler API and implementation, and doesn't have a hard limit on the number of elements like flex_array does.

Patch series "generic radix trees; drop flex arrays". This patch (of 7): There was no real need for this code to be using flexarrays, it's just implementing a hash table - ideally it would be using rhashtables, but that conversion would be significantly more complicated.

The allocated region is registered with kmemleak, but it is then removed from memblock using memblock_remove() that is not kmemleak-aware. Replacing memblock_phys_alloc_range() with memblock_find_in_range() makes sure that the allocated memory is not added to kmemleak and then memblock_remove()'ing this memory is safe. As a bonus, since memblock_find_in_range() ensures the allocation in the specified range, the bounds check can be removed.

The memblock API provides dedicated helpers to set or clear a flag on a memory region, e.g. memblock_{mark,clear}_hotplug(). The memblock_{set,clear}_region_flags() functions are used only by the memblock internal function that adjusts the region flags. Drop these functions and use open-coded implementation instead.

Add check for the return value of memblock_alloc*() functions and call panic() in case of error. The panic message repeats the one used by panicing memblock allocators with adjustment of parameters to include only relevant ones.
