Add support for Socionext Synquacer SDHCI. This binding has been in use for some time. The interrupts were not documented. The driver only uses the first interrupt, but the DT and example have 2 interrupts. The 2nd one is unknown. "dma-coherent" was also not documented, but is used on Synquacer. Signed-off-by:

Currently .get_max_clock returns the current clock rate for cclk_emmc on rk35xx, thus max clock gets set to whatever bootloader set it to. In case of u-boot, it is intentionally reset to 50 MHz if it boots from eMMC, see mmc_deinit() in u-boot sources. As a result, HS200 and HS400 modes are never selected by Linux, because dwcmshc_rk35xx_postinit clears appropriate caps if host->mmc->f_max is < 52MHz cclk_emmc is not a fixed clock on rk35xx, so using sdhci_pltfm_clk_get_max_clock is not appropriate here. Implement rk35xx_get_max_clock that returns actual max clock for cclk_emmc. Signed-off-by:

In r592_probe, dev->detect_timer was bound with r592_detect_timer. In r592_irq function, the timer function will be invoked by mod_timer. If we remove the module which will call hantro_release to make cleanup, there may be a unfinished work. The possible sequence is as follows, which will cause a typical UAF bug. Fix it by canceling the work before cleanup in r592_remove.

Add support to read the optional "gate" clock property and request the clock which will be used to ungate the DLL clock. For Xilinx platforms which has DLL module, dll clock must be ungated/enabled when SD controller operates at higher frequencies like 50 MHz, 100 MHz and 200 MHz. This will be done by explicitly requesting gate clock from the driver. Signed-off-by:

Pull tracing fixes from Steven Rostedt: - Fix setting affinity of hwlat threads in containers Using sched_set_affinity() has unwanted side effects when being called within a container. Use set_cpus_allowed_ptr() instead - Fix per cpu thread management of the hwlat tracer: - Do not start per_cpu threads if one is already running for the CPU - When starting per_cpu threads, do not clear the kthread variable as it may already be set to running per cpu threads - Fix return value for test_gen_kprobe_cmd() On error the return value was overwritten by being set to the result of the call from kprobe_event_delete(), which would likely succeed, and thus have the function return success - Fix splice() reads from the trace file that was broken by commit 36e2c742 ("fs: don't allow splice read/write without explicit ops") - Remove obsolete and confusing comment in ring_buffer.c The original design of the ring buffer used struct page flags for tricks to optimize, which was shortly removed due to them being tricks.

There is a problem with the behavior of hwlat in a container, resulting in incorrect output. A warning message is generated: "cpumask changed while in round-robin mode, switching to mode none", and the tracing_cpumask is ignored. This issue arises because the kernel thread, hwlatd, is not a part of the container, and the function sched_setaffinity is unable to locate it using its PID. Additionally, the task_struct of hwlatd is already known. Ultimately, the function set_cpus_allowed_ptr achieves the same outcome as sched_setaffinity, but employs task_struct instead of PID. Test case: # cd /sys/kernel/tracing # echo 0 > tracing_on # echo round-robin > hwlat_detector/mode # echo hwlat > current_tracer # unshare --fork --pid bash -c 'echo 1 > tracing_on' # dmesg -c Actual behavior: [573502.809060] hwlat_detector: cpumask changed while in round-robin mode, switching to mode none Link: https://lore.kernel.org/linux-trace-kernel/20230316144535.1004952-1-costa.shul@redhat.com Cc: Masami Hiramatsu <mhiramat@kernel.org> Fixes: 0330f7aa ("tracing: Have hwlat trace migrate across tracing_cpumask CPUs") Signed-off-by:

The comment refers to mm/slob.c which is being removed. It comes from commit ed56829c ("ring_buffer: reset buffer page when freeing") and according to Steven the borrowed code was a page mapcount and mapping reset, which was later removed by commit e4c2ce82 ("ring_buffer: allocate buffer page pointer"). Thus the comment is not accurate anyway, remove it.

Since the commit 36e2c742 ("fs: don't allow splice read/write without explicit ops") is applied to the kernel, splice() and sendfile() calls on the trace file (/sys/kernel/debug/tracing /trace) return EINVAL. This patch restores these system calls by initializing splice_read in file_operations of the trace file. This patch only enables such functionalities for the read case.
