regmap: Fix for v6.7
One fix here, for an interaction between noinc registers and caches - if a device uses noinc registers (which is rare) then we could corrupt registers after the noinc register in the cache. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmVKGw8ACgkQJNaLcl1U h9C8Bwf/U2a00UtJqvg+deoXHQ/7QY8w093DnHxdTLyUcDvwffbfTMrPPOmPtRLh 1OYTtPPAgcF2PjyMaazHON2Y3a1/jPLEyjfRI3UmMWoVCVObUzh30ARASdRlvZj0 1bnj88v32W2hFu/TuUPVVii3g2qH3XccEvX/JaNm0yG9lBHfugPGbVOI2S+MzWL9 iFq+nYyqi6RzD7gq99ZaoA6UdacbCyPWgvHKxoZqhknTlX/KQQDdBlq2alhmbOoU lW3t9dwtZlcoskSTmKDI7Ukz0EnRvK1fcrkhZ/3XrQl349eLmtqcG7rM/ZMoORqL wx8eoxNCyCDnjxV+QfEL6SSQEX+8Mg== =M81g -----END PGP SIGNATURE----- Merge tag 'regmap-fix-v6.7-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap fix from Mark Brown: "One fix here, for an interaction between noinc registers and caches.

sysctl-6.7-rc1
To help make the move of sysctls out of kernel/sysctl.c not incur a size penalty sysctl has been changed to allow us to not require the sentinel, the final empty element on the sysctl array. Joel Granados has been doing all this work. On the v6.6 kernel we got the major infrastructure changes required to support this. For v6.7-rc1 we have all arch/ and drivers/ modified to remove the sentinel. Both arch and driver changes have been on linux-next for a bit less than a month. It is worth re-iterating the value: - this helps reduce the overall build time size of the kernel and run time memory consumed by the kernel by about ~64 bytes per array - the extra 64-byte penalty is no longer inncurred now when we move sysctls out from kernel/sysctl.c to their own files For v6.8-rc1 expect removal of all the sentinels and also then the unneeded check for procname == NULL. The last 2 patches are fixes recently merged by Krister Johansen which allow us again to use softlockup_panic early on boot. This used to work but the alias work broke it. This is useful for folks who want to detect softlockups super early rather than wait and spend money on cloud solutions with nothing but an eventual hung kernel. Although this hadn't gone through linux-next it's also a stable fix, so we might as well roll through the fixes now. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEENnNq2KuOejlQLZofziMdCjCSiKcFAmVCqKsSHG1jZ3JvZkBr ZXJuZWwub3JnAAoJEM4jHQowkoinEgYQAIpkqRL85DBwems19Uk9A27lkctwZ6Fc HdslQCObQTsbuKVimZFP4IL2beUfUE0cfLZCXlzp+4nRDOf6vyhyf3w19jPQtI0Q YdqwTk9y6G5VjDsb35QK0+UBloY/kZ1H3/LW4uCwjXTuksUGmWW2Qvey35696Scv hDMLADqKQmdpYxLUaNi9QyYbEAjYtOai2ezg3+i7hTG168t1k/Ab2BxIFrPVsCR2 FAiq05L4ugWjNskdsWBjck05JZsx9SK/qcAxpIPoUm4nGiFNHApXE0E0hs3vsnmn WIHIbxCQw8ZlUDlmw4S+0YH3NFFzFbWfmW8k2b0f2qZTJm/rU4KiJfcJVknkAUVF raFox6XDW0AUQ9L/NOUJ9ip5rup57GcFrMYocdJ3PPAvvmHKOb1D1O741p75RRcc 9j7zwfIRrzjPUqzhsQS/GFjdJu3lJNmEBK1AcgrVry6WoItrAzJHKPPDC7TwaNmD eXpjxMl1sYzzHqtVh4hn+xkUYphj/6gTGMV8zdo+/FopFswgeJW9G8kHtlEWKDPk MRIKwACmfetP6f3ngHunBg+BOipbjCANL7JI0nOhVOQoaULxCCPx+IPJ6GfSyiuH AbcjH8DGI7fJbUkBFoF0dsRFZ2gH8ds1PYMbWUJ6x3FtuCuv5iIuvQYoaWU6itm7 6f0KvCogg0fU =Qf50 -----END PGP SIGNATURE----- Merge tag 'sysctl-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull sysctl updates from Luis Chamberlain: "To help make the move of sysctls out of kernel/sysctl.c not incur a size penalty sysctl has been changed to allow us to not require the sentinel, the final empty element on the sysctl array.

SoC driver updates for 6.7
The highlights for the driver support this time are - Qualcomm platforms gain support for the Qualcomm Secure Execution Environment firmware interface to access EFI variables on certain devices, and new features for multiple platform and firmware drivers. - Arm FF-A firmware support gains support for v1.1 specification features, in particular notification and memory transaction descriptor changes. - SCMI firmware support now support v3.2 features for clock and DVFS configuration and a new transport for Qualcomm platforms. - Minor cleanups and bugfixes are added to pretty much all the active platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic, atmel, tegra, aspeed, vexpress, mediatek, samsung and more. In particular, this contains portions of the treewide conversion to use __counted_by annotations and the device_get_match_data helper. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmVC10IACgkQYKtH/8kJ UifFoQ//Tw7aux88EA2UkyL2Wulv80NwRQn3tQlxI/6ltjBX64yeQ6Y8OzmYdSYK 20NEpbU7VWOFftN+D6Jp1HLrvfi0OV9uJn3WiTX3ChgDXixpOXo4TYgNNTlb9uZ4 MrSTG3NkS27m/oTaCmYprOObgSNLq1FRCGIP7w4U9gyMk9N9FSKMpSJjlH06qPz6 WBLTaIwPgBsyrLfCdxfA1y7AFCAHVxQJO4bp0VWSIalTrneGTeQrd2FgYMUesQ2e fIUNCaU4mpmj8XnQ/W19Wsek8FRB+fOh0hn/Gl+iHYibpxusIsn7bkdZ5BOJn2J0 OY3C1biopaaxXcZ+wmnX9X0ieZ3TDsHzYOEf0zmNGzMZaZkV8kQt4/Ykv77xz6Gc 4Bl6JI5QZ4rTZvlHYGMYxhy3hKuB31mO2rHbei7eR7J7UmjzWcl5P6HYfCgj7wzH crIWj1IR1Nx6Dt/wXf3HlRcEiAEJ2D0M3KIFjAVT239TsxacBfDrRk+YedF2bKbn WMYfVM6jJnPOykGg/gMRlttS/o/7TqHBl3y/900Idiijcm3cRPbQ+uKfkpHXftN/ 2vOtsw7pzEg7QQI9GVrb4drTrLvYJ7GQOi4o0twXTCshlXUk2V684jvHt0emFkdX ew9Zft4YLAYSmuJ3XqGhhMP63FsHKMlB1aSTKKPeswdIJmrdO80= =QIut -----END PGP SIGNATURE----- Merge tag 'soc-drivers-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC driver updates from Arnd Bergmann: "The highlights for the driver support this time are - Qualcomm platforms gain support for the Qualcomm Secure Execution Environment firmware interface to access EFI variables on certain devices, and new features for multiple platform and firmware drivers. - Arm FF-A firmware support gains support for v1.1 specification features, in particular notification and memory transaction descriptor changes. - SCMI firmware support now support v3.2 features for clock and DVFS configuration and a new transport for Qualcomm platforms. - Minor cleanups and bugfixes are added to pretty much all the active platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic, atmel, tegra, aspeed, vexpress, mediatek, samsung and more.

regmap: prevent noinc writes from clobbering cache
Currently, noinc writes are cached as if they were standard incrementing
writes, overwriting unrelated register values in the cache. Instead, we
want to cache the last value written to the register, as is done in the
accelerated noinc handler (regmap_noinc_readwrite).

regmap: Updates for v6.7
The main change here is a fix for an issue where we were letting the selector for windowed register ranges get out of sync with the hardware during a cache sync plus associated KUnit tests. This was reported just at the end of the release cycle and only in -next for a day prior to the merge window so it seemed better to hold off for now, the bug had been present for more than a decade so wasn't causing too many practical problems hopefully. There's also a fix for error handling in the debugfs output from Christope Jaillet. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmU/qxsACgkQJNaLcl1U h9CvIgf+JL9LrFApTZliWjEPg1K8CxhRzoFRxUb0tP47f0cJ7zJ6+5uv5GGbfj3N liZvRIMetTs8jk4T/avahS1t55XZ9EkGlItsAFny83otfOw5xA6WOqFTRl5D39G6 yHSJw1gyX+4L5lhJrWbEZG7/SgpKjptZQH6j1/4cwXYTU19gpriypJi4P9nBOzyw GXJqQzTgq8LMdF7twPLR6QipgoE5Z3Oum6qM6C8FfibH/+AsbctzboUhXpJxIO2j CdnYxCkW2Bu8Y0ngkayz0Hj6UnEntRpHklzJeSiP0cVy8xm4DemFSbOB5l6dQ20O RWwpnXfQPYtaMzruKRd3FYNQRrOM9Q== =mrBL -----END PGP SIGNATURE----- Merge tag 'regmap-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap updates from Mark Brown: "The main change here is a fix for an issue where we were letting the selector for windowed register ranges get out of sync with the hardware during a cache sync plus associated KUnit tests.

firmware_loader: Abort all upcoming firmware load request once reboot triggered
There could be following scenario where there is a ongoing reboot is going from processA which tries to call all the reboot notifier callback and one of them is firmware reboot call which tries to abort all the ongoing firmware userspace request under fw_lock but there could be another processB which tries to do request firmware, which came just after abort done from ProcessA and ask for userspace to load the firmware and this can stop the ongoing reboot ProcessA to stall for next 60s(default timeout) which may not be expected behaviour everyone like to see, instead we should abort any firmware load request which came once firmware knows about the reboot through notification.

regmap: Ensure range selector registers are updated after cache sync
When we sync the register cache we do so with the cache bypassed in order to avoid overhead from writing the synced values back into the cache. If the regmap has ranges and the selector register for those ranges is in a register which is cached this has the unfortunate side effect of meaning that the physical and cached copies of the selector register can be out of sync after a cache sync. The cache will have whatever the selector was when the sync started and the hardware will have the selector for the register that was synced last. Fix this by rewriting all cached selector registers after every sync, ensuring that the hardware and cache have the same content. This will result in extra writes that wouldn't otherwise be needed but is simple so hopefully robust. We don't read from the hardware since not all devices have physical read support. Given that nobody noticed this until now it is likely that we are rarely if ever hitting this case.

regmap: kunit: Add test for cache sync interaction with ranges
Hector Martin reports that since when doing a cache sync we enable cache bypass if the selector register for a range is cached then we might leave the physical selector register pointing to a different value to that which we have in the cache. If we then try to write to the page that our cache tells us is selected we will not update the selector register and write to the wrong page. Add a test case covering this.

cacheinfo: calculate size of per-CPU data cache slice
This can be used to estimate the size of the data cache slice that can be used by one CPU under ideal circumstances. Both DATA caches and UNIFIED caches are used in calculation. So, the users need to consider the impact of the code cache usage. Because the cache inclusive/non-inclusive information isn't available now, we just use the size of the per-CPU slice of LLC to make the result more predictable across architectures. This may be improved when more cache information is available in the future. A brute-force algorithm to iterate all online CPUs is used to avoid to allocate an extra cpumask, especially in offline callback.

Moreover, let's add a function, dev_pm_domain_set_performance_state(), that may be called by consumers to request a new performance state for a device through its PM domain. Note that, in most cases it's preferred that a consumer use the OPP library to request a new performance state for its device.

regmap: rbtree: Fix wrong register marked as in-cache when creating new node
When regcache_rbtree_write() creates a new rbtree_node it was passing the
wrong bit number to regcache_rbtree_set_register(). The bit number is the
offset __in number of registers__, but in the case of creating a new block
regcache_rbtree_write() was not dividing by the address stride to get the
number of registers.
Fix this by dividing by map->reg_stride.
Compare with regcache_rbtree_read() where the bit is checked.
This bug meant that the wrong register was marked as present. The register
that was written to the cache could not be read from the cache because it
was not marked as cached. But a nearby register could be marked as having
a cached value even if it was never written to the cache.

This pull request is full of clk driver changes. In fact, there aren't any
changes to the clk framework this time around. That's probably because everyone was on vacation (yours truly included). We did lose a couple clk drivers this time around because nobody was using those devices. That skews the diffstat a bit, but either way, nothing looks out of the ordinary here. The usual suspects are chugging along adding support for more SoCs and fixing bugs. If I had to choose, I'd say the theme for the past few months has been "polish". There's quite a few patches that migrate to devm_platform_ioremap_resource() in here. And there's more than a handful of patches that move the NR_CLKS define from the DT binding header to the driver. There's even patches that migrate drivers to use clk_parent_data and clk_hw to describe clk tree topology. It seems that the spring (summer?) cleaning bug got some folks, or the semiconductor shortage finally hit the software side. New Drivers: - StarFive JH7110 SoC clock drivers - Qualcomm IPQ5018 Global Clock Controller driver - Versa3 clk generator to support 48KHz playback/record with audio codec on RZ/G2L SMARC EVK Removed Drivers: - Remove non-OF mmp clk drivers - Remove OXNAS clk driver Updates: - Add __counted_by to struct clk_hw_onecell_data and struct spmi_pmic_div_clk_cc - Move defines for numbers of clks (NR_CLKS) from DT headers to drivers - Introduce kstrdup_and_replace() and use it - Add PLL rates for Rockchip rk3568 - Add the display clock tree for Rockchip rv1126 - Add Audio Clock Generator (ADG) clocks on Renesas R-Car Gen3 and RZ/G2 SoCs - Convert sun9i-mmc clock to use devm_platform_get_and_ioremap_resource() - Fix function name in a comment in ccu_mmc_timing.c - Parameter name correction for ccu_nkm_round_rate() - Implement CLK_SET_RATE_PARENT for Allwinner NKM clocks, i.e. consider alternative parent rates when determining clock rates - Set CLK_SET_RATE_PARENT for Allwinner A64 pll-mipi - Support finding closest (as opposed to closest but not higher) clock rate for NM, NKM, mux and div type clocks, as use it for Allwinner A64 pll-video0 - Prefer current parent rate if able to generate ideal clock rate for Allwinner NKM clocks - Clean up Qualcomm SMD RPM driver, with interconnect bus clocks moved out to the interconnect drivers - Fix various PM runtime bugs across many Qualcomm clk drivers - Migrate Qualcomm MDM9615 is to parent_hw and parent_data - Add network related resets on Qualcomm IPQ4019 - Add a couple missing USB related clocks to Qualcomm IPQ9574 - Add missing gpll0_sleep_clk_src to Qualcomm MSM8917 global clock controller - In the Qualcomm QDU1000 global clock controller, GDSCs, clkrefs, and GPLL1 are added, while PCIe pipe clock, SDCC rcg ops are corrected - Add missing GDSCs to and correct GDSCs for the SC8280XP global clock controller driver - Support retention for the Qualcomm SC8280XP display clock controller GDSCs. - Qualcommm's SDCC apps_clk_src is marked with CLK_OPS_PARENT_ENABLE to fix issues with missing parent clocks across sc7180, sm7150, sm6350 and sm8250, while sm8450 is corrected to use floor ops - Correct Qualcomm SM6350 GPU clock controller's clock supplies - Drop unwanted clocks from the Qualcomm IPQ5332 GCC driver - Add missing OXILICX GDSC to Qualcomm MSM8226 GCC - Change the delay in the Qualcomm reset controller to fsleep() for correctness - Extend the Qualcomm SM83550 Video clock controller to support SC8280XP - Add graphics clock support on Renesas RZ/G2M, RZ/G2N, RZ/G2E, and R-Car H3, M3-W, and M3-N SoCs - Add Clocked Serial Interface (CSI) clocks on Renesas RZ/V2M - Add PWM (MTU3) clock and reset on Renesas RZ/G2UL and RZ/Five - Add the PDM IPC clock for i.MX93 - Add 519.75MHz frequency support for i.MX9 PLL - Simplify the .determine_rate() implementation for i.MX GPR mux - Make the i.MX8QXP LPCG clock use devm_platform_ioremap_resource() - Add the audio mux clock to i.MX8 - Fix the SPLL2 MULT range for PLLv4 - Update the SPLL2 type in i.MX8ULP - Fix the SAI4 clock on i.MX8MP - Add silicon revision print for i.MX25 on clocks init - Drop the return value from __mx25_clocks_init() - Fix the clock pauses on no-op set_rate for i.MX8M composite clock - Drop restrictions for i.MX PLL14xx and fix its max prediv value - Drop the 393216000 and 361267200 from i.MX PLL14xx rate table to allow glitch free switching -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEE9L57QeeUxqYDyoaDrQKIl8bklSUFAmTv2wkRHHNib3lkQGtl cm5lbC5vcmcACgkQrQKIl8bklSW1LRAAuHR2HoyB4bRHmCa1bfOfYYDfSWsBWEav tWIfBl86Nl/Je50Gk2NJ9vqU5OPqRZ57TIniijHHoX5n7/kYcr8KVmlomY07hUeg CzWyothkxg4k7+rQwVAWvmlR2YAVwzHDKcwq7gkMZOnW/y26LXip99cjopu2CJLx zVwTgvWollmd4KVlicnAlx4zUjgNkWR24iA4Lcf5ir+Dr6FYNjxLI+akBA8EPxxi wLixZbScgBSgpGn6KVgoFhclCToPS0gt5m6HfQxJ/svOCU54l+jRKpzkNZGWvyu4 A8t3CRrwL2iS/mfCGk2yRlaKySoLLpjlpW1AI7fHTWbG2P6p8ZphtN7jOeeAEsbq TNpzWEjtY6B/lfRzxxINXkrtLaqmlnFY/P5np5fDrf/61gRFxLFQemyRdY/xCSJf Kwq8ja1mrSGWoDGG9XhDqTf9Yek9LRObNzlDrEmn/i/qLTcxhOIz58pzHg4iAlx5 9HDtnJ8hKg4uE1TtT12Bmasb1+WzG7GYYESNfKWZhCvbRqEUzcDOHk7xpwYa1ffx yZIgMs7Sb/exNW8LMPYmgnyj/f9eo5IdjiQvune+Zy5NrdzfyN6Sf/LSibrqCF2z X5aFHqQrR8+PifD+se+g5HPa0ezSmBIhXzYUTOC6f+nywlrJjhwDXPDYI6Lcd//p r4mpOmJS+G4= =h2Jz -----END PGP SIGNATURE----- Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk subsystem updates from Stephen Boyd: "This pull request is full of clk driver changes.

Devicetree updates for v6.6:
DT core: - Add support for generating DT nodes for PCI devices. This is the groundwork for applying overlays to PCI devices containing non-discoverable downstream devices. - DT unittest additions to check reverted changesets, to test for refcount issues, and to test unresolved symbols. Also, various clean-ups of the unittest along the way. - Refactor node and property manipulation functions to better share code with old API and changeset API - Refactor changeset print functions to a common implementation - Move some platform_device specific functions into of_platform.c Bindings: - Treewide fixing of typos - Treewide clean-up of SPDX tags to use 'OR' consistently - Last chunk of dropping unnecessary quotes. With that, the check for unnecessary quotes is enabled in yamllint. - Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi bindings to DT schema format - Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450 Inline Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt controller, Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings - Fixes for Rockchip DWC PCI binding - Ensure all properties are evaluated on USB connector schema - Fix dt-check-compatible script to find of_device_id instances with compiler annotations -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEktVUI4SxYhzZyEuo+vtdtY28YcMFAmTubyoACgkQ+vtdtY28 YcPamA//feXFYNPiIbSa7XqfAu1PE5XSg3PqCe77QvLBGJU7saTwRJApc88iTjlA hc5EELnZKp3FE9N7DJdmvEjYxKDqtJOukO+txKy3mFBWo+gZQURthZVcbLxUZmpw XmYA4b/GrIv5h8YWG1wokyaGTtSfTcf0+RmAtVepiDk5kWQKaC04Let356fKn9xi ePgLTZV6BJvPoGpMWd08o+1szUAc6Vihs9qWu7g0+mtb5K5xi/l05YMz3REu7kpf iz06CE/uzYvHpFBJZ6izN+9Qqxh52DnWckXX68v8kStHUON2h1YmZYvjhGrfay4k rHeDnHoRBrepDDCytXQ/fxzGtURr3b8yBnlhzEQadMLXmf25mm+TRBDmf6GnX5ij QmHlj+eSARIafcbb4fqF1Hdyv8c7XM0AkEnj1XrIWLtXPuRNSHlS25dngCztbII/ lqmtBaH1ifCKj2VQ8YL8sVX7k208YU9vDNKZHQyA8dPEYwhknrWmp1F0OAnBB+wz F11kDE7xkZ0/gE7mUHwe9mP94hC6Ceks4IuBvsTzBmSwqXxyCz8gM2KHK4U3gNUr Sk2hWgZn+k2HM9zLb38FE18C6hqws6RBUWnJwZ4V3qPo2eYJ8Jzkvm7oonxjHgCC 4FmYYAoCQhBEkZPOJ4map0eO5VbShn9Hrgs46Jj4WoXmm7dFDLc= =kl+z -----END PGP SIGNATURE----- Merge tag 'devicetree-for-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull devicetree updates from Rob Herring: "DT core: - Add support for generating DT nodes for PCI devices.

crash: memory and CPU hotplug sysfs attributes
Introduce the crash_hotplug attribute for memory and CPUs for use by userspace. These attributes directly facilitate the udev rule for managing userspace re-loading of the crash kernel upon hot un/plug changes. For memory, expose the crash_hotplug attribute to the /sys/devices/system/memory directory. For example: # udevadm info --attribute-walk /sys/devices/system/memory/memory81 looking at device '/devices/system/memory/memory81': KERNEL=="memory81" SUBSYSTEM=="memory" DRIVER=="" ATTR{online}=="1" ATTR{phys_device}=="0" ATTR{phys_index}=="00000051" ATTR{removable}=="1" ATTR{state}=="online" ATTR{valid_zones}=="Movable" looking at parent device '/devices/system/memory': KERNELS=="memory" SUBSYSTEMS=="" DRIVERS=="" ATTRS{auto_online_blocks}=="offline" ATTRS{block_size_bytes}=="8000000" ATTRS{crash_hotplug}=="1" For CPUs, expose the crash_hotplug attribute to the /sys/devices/system/cpu directory. For example: # udevadm info --attribute-walk /sys/devices/system/cpu/cpu0 looking at device '/devices/system/cpu/cpu0': KERNEL=="cpu0" SUBSYSTEM=="cpu" DRIVER=="processor" ATTR{crash_notes}=="277c38600" ATTR{crash_notes_size}=="368" ATTR{online}=="1" looking at parent device '/devices/system/cpu': KERNELS=="cpu" SUBSYSTEMS=="" DRIVERS=="" ATTRS{crash_hotplug}=="1" ATTRS{isolated}=="" ATTRS{kernel_max}=="8191" ATTRS{nohz_full}==" (null)" ATTRS{offline}=="4-7" ATTRS{online}=="0-3" ATTRS{possible}=="0-7" ATTRS{present}=="0-3" With these sysfs attributes in place, it is possible to efficiently instruct the udev rule to skip crash kernel reloading for kernels configured with crash hotplug support. For example, the following is the proposed udev rule change for RHEL system 98-kexec.rules (as the first lines of the rule file): # The kernel updates the crash elfcorehdr for CPU and memory changes SUBSYSTEM=="cpu", ATTRS{crash_hotplug}=="1", GOTO="kdump_reload_end" SUBSYSTEM=="memory", ATTRS{crash_hotplug}=="1", GOTO="kdump_reload_end" When examined in the context of 98-kexec.rules, the above rules test if crash_hotplug is set, and if so, the userspace initiated unload-then-reload of the crash kernel is skipped. CPU and memory checks are separated in accordance with CONFIG_HOTPLUG_CPU and CONFIG_MEMORY_HOTPLUG kernel config options. If an architecture supports, for example, memory hotplug but not CPU hotplug, then the /sys/devices/system/memory/crash_hotplug attribute file is present, but the /sys/devices/system/cpu/crash_hotplug attribute file will NOT be present. Thus the udev rule skips userspace processing of memory hot un/plug events, but the udev rule will evaluate false for CPU events, thus allowing userspace to process CPU hot un/plug events (ie the unload-then-reload of the kdump capture kernel).

driver core: Call in reversed order in device_platform_notify_remove()
It's logically correct to call the removal notifiers in the reversed order as it might be dependent to each other. Luckily, platform_notify_remove() currently is not used and the others have no dependency use, but theoretically it's still possible.
