Pull clk updates from Stephen Boyd: "Not a ton of stuff happening in the clk framework. We got some more devm helpers and we seem to be going in the direction of "just turn this stuff on already and leave me alone!" with the addition of a devm_clk_bulk_get_all_enable() API. I'm hoping that we can make that into a pmdomain that drivers attach instead, but this API should help drivers simplify in the meantime. Outside of the devm wrappers, we've got the usual clk driver updates that are dominated by the major phone SoC vendors (Samsung and Qualcomm) and the non-critical driver fixes for things like incorrect topology descriptions and wrong registers or bit fields. More details are below, but I'd say that it looks pretty ordinary. The only thing that really jumps out at me is the Renesas clk driver that's ignoring clks that are assigned to remote processors in DeviceTree. That's a new feature that they're using to avoid marking clks as CLK_IGNORE_UNUSED based on the configuration of the system. Core: - Increase dev_id len for clkdev lookups - Add a devm_clk_bulk_get_all_enable() API to get and enable all clks for a device - Add a devm variant of clk_rate_exclusive_get() New Drivers: - Display, TCSR, GPU, and Camera clock controllers for Qualcomm's X1 Elite SoC - Google GS101 PERIC0 and PERIC1 clock controllers - Exynos850 PDMA clocks - Exynos850 CPU cluster 0 and 1 (CMU_CPUCLK0/CMU_CPUCLK1) clock controllers Removed Drivers: - Remove the unused Qualcomm sc7180 modem clk driver Updates: - Fix some static checker errors in the Hisilicon clk driver - Polarfire MSSPLL hardware has 4 output clocks (the driver supported previously only one output); each of these 4 outputs feed dividers and the output of each divider feed individual hardware blocks (e.g. CAN, Crypto, eMMC); individual hardware block drivers need to control their clocks thus clock driver support was added for all MSSPLL output clocks - Typo fixes in the Qualcomm IPQ5018 GCC driver - Add "qdss_at" clk on Qualcomm IPQ6018, needed for WiFi - Properly terminate frequency tables in different Qualcomm clk drivers - Add MDSS, crypto, and SDCC resets on Qualcomm MSM8953 - Add missing UFS CLKREF clks on Qualcomm SC8180X - Avoid significant delays during boot by adding a softdep on rpmhpd to Qualcomm SDM845 gcc driver - Add QUPv3 RCGS w/ DFS and video resets to Qualcomm SM8150 GCC driver - Fix the custom GPU GX "do-nothing" method in the Qualcomm GDSC driver - Add an external regulator to GX GDSC on Qualcomm SC8280XP GPU clk driver - Switch display, GPU, video, and camera Qualcomm clk drivers to module_platform_driver() - Set a longer delay for Venus resets on many Qualcomm SoCs - Correct the GDSC wait times in the Qualcomm SDM845 display clk driver - Fix clock listing Oops on Amlogic axg - New pll-rate for Rockchip rk3568 - i2s rate improvements for Rockchip rk3399 - Rockchip rk3588 syscon clock fixes and removal of overall clock-number from the rk3588 binding header - A prerequisite for later improvements to the Rockchip rk3588 linked clocks - Minor clean-ups and error handling improvements in both composite-8m and SCU i.MX clock drivers - Fix for SAI_MCLK_SEL definition for i.MX8MP - Register the Samsung CMU MISC clock controller earlier, so the Multi Core Timer clocksource can use it on Google GS101 - Propagate Exynos850 SPI IPCLK rate change to parents, so the SPI will get proper clock rates - Refactor the generic Samsung CPU clock controllers code, preparing it for supporting Exynos850 CPU clocks - Fix some clk kerneldoc warnings - Add Ethernet, SDHI, DMA, and HyperFLASH/QSPI (RPC-IF) clocks on Renesas R-Car V4M - Ignore all clocks which are assigned to a non-Linux system in the Renesas clk driver - Add watchdog clock on Renesas RZ/G3S - Add camera (CRU) clock and reset on Renesas RZ/G2UL - Add support for the Renesas R-Car V4M (R8A779H0) SoC - Convert some clk bindings to YAML so they can be validated" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (150 commits) clk: zynq: Prevent null pointer dereference caused by kmalloc failure clk: fractional-divider: Use bit operations consistently clk: fractional-divider: Move mask calculations out of lock clk: Fix clk_core_get NULL dereference clk: starfive: jh7110-vout: Convert to platform remove callback returning void clk: starfive: jh7110-isp: Convert to platform remove callback returning void clk: imx: imx8-acm: Convert to platform remove callback returning void clk: qcom: gcc-ipq5018: fix register offset for GCC_UBI0_AXI_ARES reset clk: qcom: gcc-ipq5018: fix 'halt_reg' offset of 'gcc_pcie1_pipe_clk' clk: qcom: gcc-ipq5018: fix 'enable_reg' offset of 'gcc_gmac0_sys_clk' clk: qcom: camcc-x1e80100: Fix missing DT_IFACE enum in x1e80100 camcc clk: qcom: mmcc-msm8974: fix terminating of frequency table arrays clk: qcom: mmcc-apq8084: fix terminating of frequency table arrays clk: qcom: camcc-sc8280xp: fix terminating of frequency table arrays clk: qcom: gcc-ipq9574: fix terminating of frequency table arrays clk: qcom: gcc-ipq8074: fix terminating of frequency table arrays clk: qcom: gcc-ipq6018: fix terminating of frequency table arrays clk: qcom: gcc-ipq5018: fix terminating of frequency table arrays clk: mediatek: clk-mt8173-apmixedsys: Use common error handling code in clk_mt8173_apmixed_probe() clk: Add a devm variant of clk_rate_exclusive_get() ...

Pull MM updates from Andrew Morton: - Sumanth Korikkar has taught s390 to allocate hotplug-time page frames from hotplugged memory rather than only from main memory. Series "implement "memmap on memory" feature on s390". - More folio conversions from Matthew Wilcox in the series "Convert memcontrol charge moving to use folios" "mm: convert mm counter to take a folio" - Chengming Zhou has optimized zswap's rbtree locking, providing significant reductions in system time and modest but measurable reductions in overall runtimes. The series is "mm/zswap: optimize the scalability of zswap rb-tree". - Chengming Zhou has also provided the series "mm/zswap: optimize zswap lru list" which provides measurable runtime benefits in some swap-intensive situations. - And Chengming Zhou further optimizes zswap in the series "mm/zswap: optimize for dynamic zswap_pools". Measured improvements are modest. - zswap cleanups and simplifications from Yosry Ahmed in the series "mm: zswap: simplify zswap_swapoff()". - In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has contributed several DAX cleanups as well as adding a sysfs tunable to control the memmap_on_memory setting when the dax device is hotplugged as system memory. - Johannes Weiner has added the large series "mm: zswap: cleanups", which does that. - More DAMON work from SeongJae Park in the series "mm/damon: make DAMON debugfs interface deprecation unignorable" "selftests/damon: add more tests for core functionalities and corner cases" "Docs/mm/damon: misc readability improvements" "mm/damon: let DAMOS feeds and tame/auto-tune itself" - In the series "mm/mempolicy: weighted interleave mempolicy and sysfs extension" Rakie Kim has developed a new mempolicy interleaving policy wherein we allocate memory across nodes in a weighted fashion rather than uniformly. This is beneficial in heterogeneous memory environments appearing with CXL. - Christophe Leroy has contributed some cleanup and consolidation work against the ARM pagetable dumping code in the series "mm: ptdump: Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute". - Luis Chamberlain has added some additional xarray selftesting in the series "test_xarray: advanced API multi-index tests". - Muhammad Usama Anjum has reworked the selftest code to make its human-readable output conform to the TAP ("Test Anything Protocol") format. Amongst other things, this opens up the use of third-party tools to parse and process out selftesting results. - Ryan Roberts has added fork()-time PTE batching of THP ptes in the series "mm/memory: optimize fork() with PTE-mapped THP". Mainly targeted at arm64, this significantly speeds up fork() when the process has a large number of pte-mapped folios. - David Hildenbrand also gets in on the THP pte batching game in his series "mm/memory: optimize unmap/zap with PTE-mapped THP". It implements batching during munmap() and other pte teardown situations. The microbenchmark improvements are nice. - And in the series "Transparent Contiguous PTEs for User Mappings" Ryan Roberts further utilizes arm's pte's contiguous bit ("contpte mappings"). Kernel build times on arm64 improved nicely. Ryan's series "Address some contpte nits" provides some followup work. - In the series "mm/hugetlb: Restore the reservation" Breno Leitao has fixed an obscure hugetlb race which was causing unnecessary page faults. He has also added a reproducer under the selftest code. - In the series "selftests/mm: Output cleanups for the compaction test", Mark Brown did what the title claims. - Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring". - Even more zswap material from Nhat Pham. The series "fix and extend zswap kselftests" does as claimed. - In the series "Introduce cpu_dcache_is_aliasing() to fix DAX regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in our handling of DAX on archiecctures which have virtually aliasing data caches. The arm architecture is the main beneficiary. - Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic improvements in worst-case mmap_lock hold times during certain userfaultfd operations. - Some page_owner enhancements and maintenance work from Oscar Salvador in his series "page_owner: print stacks and their outstanding allocations" "page_owner: Fixup and cleanup" - Uladzislau Rezki has contributed some vmalloc scalability improvements in his series "Mitigate a vmap lock contention". It realizes a 12x improvement for a certain microbenchmark. - Some kexec/crash cleanup work from Baoquan He in the series "Split crash out from kexec and clean up related config items". - Some zsmalloc maintenance work from Chengming Zhou in the series "mm/zsmalloc: fix and optimize objects/page migration" "mm/zsmalloc: some cleanup for get/set_zspage_mapping()" - Zi Yan has taught the MM to perform compaction on folios larger than order=0. This a step along the path to implementaton of the merging of large anonymous folios. The series is named "Enable >0 order folio memory compaction". - Christoph Hellwig has done quite a lot of cleanup work in the pagecache writeback code in his series "convert write_cache_pages() to an iterator". - Some modest hugetlb cleanups and speedups in Vishal Moola's series "Handle hugetlb faults under the VMA lock". - Zi Yan has changed the page splitting code so we can split huge pages into sizes other than order-0 to better utilize large folios. The series is named "Split a folio to any lower order folios". - David Hildenbrand has contributed the series "mm: remove total_mapcount()", a cleanup. - Matthew Wilcox has sought to improve the performance of bulk memory freeing in his series "Rearrange batched folio freeing". - Gang Li's series "hugetlb: parallelize hugetlb page init on boot" provides large improvements in bootup times on large machines which are configured to use large numbers of hugetlb pages. - Matthew Wilcox's series "PageFlags cleanups" does that. - Qi Zheng's series "minor fixes and supplement for ptdesc" does that also. S390 is affected. - Cleanups to our pagemap utility functions from Peter Xu in his series "mm/treewide: Replace pXd_large() with pXd_leaf()". - Nico Pache has fixed a few things with our hugepage selftests in his series "selftests/mm: Improve Hugepage Test Handling in MM Selftests". - Also, of course, many singleton patches to many things.

Merge tag 'trace-ring-buffer-v6.8-rc7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing updates from Steven Rostedt: - Do not update shortest_full in rb_watermark_hit() if the watermark is hit. The shortest_full field was being updated regardless if the task was going to wait or not. If the watermark is hit, then the task is not going to wait, so do not update the shortest_full field (used by the waker). - Update shortest_full field before setting the full_waiters_pending flag In the poll logic, the full_waiters_pending flag was being set before the shortest_full field was set. If the full_waiters_pending flag is set, writers will check the shortest_full field which has the least percentage of data that the ring buffer needs to be filled before waking up. The writer will check shortest_full if full_waiters_pending is set, and if the ring buffer percentage filled is greater than shortest full, then it will call the irq_work to wake up the waiters. The problem was that the poll logic set the full_waiters_pending flag before updating shortest_full, which when zero will always trigger the writer to call the irq_work to wake up the waiters. The irq_work will reset the shortest_full field back to zero as the woken waiters is suppose to reset it. - There's some optimized logic in the rb_watermark_hit() that is used in ring_buffer_wait(). Use that helper function in the poll logic as well. - Restructure ring_buffer_wait() to use wait_event_interruptible() The logic to wake up pending readers when the file descriptor is closed is racy. Restructure ring_buffer_wait() to allow callers to pass in conditions besides the ring buffer having enough data in it by using wait_event_interruptible(). - Update the tracing_wait_on_pipe() to call ring_buffer_wait() with its own conditions to exit the wait loop. * tag 'trace-ring-buffer-v6.8-rc7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing/ring-buffer: Fix wait_on_pipe() race ring-buffer: Use wait_event_interruptible() in ring_buffer_wait() ring-buffer: Reuse rb_watermark_hit() for the poll logic ring-buffer: Fix full_waiters_pending in poll ring-buffer: Do not set shortest_full when full target is hit

Pull lsm fixes from Paul Moore: "Two fixes to address issues with the LSM syscalls that we shipped in Linux v6.8. The first patch might be a bit controversial, but the second is a rather straightforward fix; more on both below. The first fix from Casey addresses a problem that should have been caught during the ~16 month (?) review cycle, but sadly was not. The good news is that Dmitry caught it very quickly once Linux v6.8 was released. The core issue is the use of size_t parameters to pass buffer sizes back and forth in the syscall; while we could have solved this with a compat syscall definition, given the newness of the syscalls I wanted to attempt to just redefine the size_t parameters as u32 types and avoid the work associated with a set of compat syscalls. However, this is technically a change in the syscall's signature/API so I can understand if you're opposed to this, even if the syscalls are less than a week old. [ Fingers crossed nobody even notices - Linus ] The second fix is a rather trivial fix to allow userspace to call into the lsm_get_self_attr() syscall with a NULL buffer to quickly determine a minimum required size for the buffer. We do have kselftests for this very case, I'm not sure why I didn't notice the failure; I'm going to guess stupidity, tired eyes, I dunno. My apologies we didn't catch this earlier" * tag 'lsm-pr-20240314' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: lsm: handle the NULL buffer case in lsm_fill_user_ctx() lsm: use 32-bit compatible data types in LSM syscalls

The cont_read.ongoing flag should only be enabled at the beginning of a read operation, and also disabled at its end, so we never end up triggering nasty side effects outside of this scope. The mtd core being highly serialized, we should not be bothered by parallel accesses anyway. In case we reach the end of a read operation and the boolean was not properly disabled, it's a bug, but it's totally manageable. So warn, and then fix the boolean state. Signed-off-by:

As a matter of fact, continuous reads require additional handling at the operation level in order for them to work properly. The core helpers do have this additional logic now, but any time a controller implements its own page helper, this extra logic is "lost". This means we need another level of per-controller driver checks to ensure they can leverage continuous reads. This is for now unsupported, so in order to ensure continuous reads are enabled only when fully using the core page helpers, we need to add more initial checks. Also, as performance is not relevant during raw accesses, we also prevent these from enabling the feature. This should solve the issue seen with controllers such as the STM32 FMC2 when in sequencer mode. In this case, the continuous read feature would be enabled but not leveraged, and most importantly not disabled, leading to further operations to fail. Reported-by:

While crossing a LUN boundary, it is probably safer (and clearer) to keep all members of the continuous read structure aligned, including the pause page (which is the last page of the lun or the last page of the continuous read).

The BCMBCA broadband SoC integrates the NAND controller differently than STB, iProc and other SoCs. It has different endianness for NAND cache data. Add a SoC read data bus shim for BCMBCA to meet the specific SoC need and performance improvement using the optimized memcpy function on NAND cache memory. Signed-off-by:

Enable the nand controller and add WP pin connection property in actual board dts as they are board level properties now that they are disabled and moved out from SoC dtsi. Also remove the unnecessary brcm,nand-has-wp property from AC5300 board. This property is only needed for some old controller that this board does not apply. Signed-off-by:
