RISC-V: cpu_ops_spinwait.c should include head.h
Running sparse shows cpu_ops_spinwait.c is missing two definitions
found in head.h, so include it to stop the following warnings:
arch/riscv/kernel/cpu_ops_spinwait.c:15:6: warning: symbol '__cpu_spinwait_stack_pointer' was not declared. Should it be static?
arch/riscv/kernel/cpu_ops_spinwait.c:16:6: warning: symbol '__cpu_spinwait_task_pointer' was not declared. Should it be static?

RISC-V: Declare cpu_ops_spinwait in <asm/cpu_ops.h>
The cpu_ops_spinwait is used in a couple of places in arch/riscv
and is causing a sparse warning due to no declaration. Add this
to <asm/cpu_ops.h> with the others to fix the following:
arch/riscv/kernel/cpu_ops_spinwait.c:16:29: warning: symbol 'cpu_ops_spinwait' was not declared. Should it be static?

riscv: dts: starfive: correct number of external interrupts
The PLIC integrated on the Vic_U7_Core integrated on the StarFive
JH7100 SoC actually supports 133 external interrupts. 127 of these
are exposed to the outside world; the remainder are used by other
devices that are part of the core-complex such as the L2 cache
controller. But all 133 interrupts are external interrupts as far
as the PLIC is concerned. Fix the property so that the driver can
manage these additional interrupts, which is important since the
interrupts for the L2 cache controller are enabled by default.

RISC-V: Add modules to virtual kernel memory layout dump
Modules always live before the kernel, MODULES_END is fixed but
MODULES_VADDR isn't fixed, it depends on the kernel size.
Let's add it to virtual kernel memory layout dump.
As MODULES is only defined for CONFIG_64BIT, so we dump it when
CONFIG_64BIT=y.
eg,
MODULES_VADDR - MODULES_END
0xffffffff01133000 - 0xffffffff80000000

RISC-V: Fixup schedule out issue in machine_crash_shutdown()
Current task of executing crash kexec will be schedule out when panic is
triggered by RCU Stall, as it needs to wait rcu completion. It lead to
inability to enter the crash system.
The implementation of machine_crash_shutdown() is non-standard for RISC-V
according to other Arch's implementation(eg, x86, arm64), we need to send
IPI to stop secondary harts.

RISC-V: Fixup get incorrect user mode PC for kernel mode regs
When use 'echo c > /proc/sysrq-trigger' to trigger kdump, riscv_crash_save_regs()
will be called to save regs for vmcore, we found "epc" value 00ffffffa5537400
is not a valid kernel virtual address, but is a user virtual address. Other
regs(eg, ra, sp, gp...) are correct kernel virtual address.
Actually 0x00ffffffb0dd9400 is the user mode PC of 'PID: 113 Comm: sh', which
is saved in the task's stack.

riscv: implement Zicbom-based CMO instructions + the t-head variant
This series is based on the alternatives changes done in my svpbmt series and thus also depends on Atish's isa-extension parsing series. It implements using the cache-management instructions from the Zicbom- extension to handle cache flush, etc actions on platforms needing them. SoCs using cpu cores from T-Head like the Allwinne D1 implement a different set of cache instructions. But while they are different, instructions they provide the same functionality, so a variant can easly hook into the existing alternatives mechanism on those. [Palmer: Some minor fixups, including a RISCV_ISA_ZICBOM dependency on MMU that's probably not strictly necessary. The Zicbom support will trip up sparse for users that have new toolchains, I just sent a patch.] Link: https://lore.kernel.org/all/20220706231536.2041855-1-heiko@sntech.de/ Link: https://lore.kernel.org/linux-sparse/20220811033138.20676-1-palmer@rivosinc.com/T/#u * palmer/riscv-zicbom: riscv: implement cache-management errata for T-Head SoCs riscv: Add support for non-coherent devices using zicbom extension dt-bindings: riscv: document cbom-block-size of: also handle dma-noncoherent in of_dma_is_coherent() |

RISC-V: Canaan devicetree fixes
This series should rid us of dtbs_check errors for the RISC-V Canaan k210 based boards. To make keeping it that way a little easier, I changed the Canaan devicetree Makefile so that it would build all of the devicetrees in the directory if SOC_CANAAN.

- Add flags argument to dm_bufio_client_create and introduce
DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather than mutex for its locking. - Add optional "try_verify_in_tasklet" feature to DM verity target. This feature gives users the option to improve IO latency by using a tasklet to verify, using hashes in bufio's cache, rather than wait to schedule a work item via workqueue. But if there is a bufio cache miss, or an error, then the tasklet will fallback to using workqueue. - Incremental changes to both dm-bufio and the DM verity target to use jump_label to minimize cost of branching associated with the niche "try_verify_in_tasklet" feature. DM-bufio in particular is used by quite a few other DM targets so it doesn't make sense to incur additional bufio cost in those targets purely for the benefit of this niche verity feature if the feature isn't ever used. - Optimize verity_verify_io, which is used by both workqueue and tasklet based verification, if FEC is not configured or tasklet based verification isn't used. - Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE flag since it uses WQ_UNBOUND. Also, use the WQ_HIGHPRI flag if "try_verify_in_tasklet" is specified. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAmLtYU0ACgkQxSPxCi2d A1pIDwgAjQi7jSxN7n+Fb4sJLL5x3WvuVGcockIkucj+Pvr3nvijwkf27+kbCWhn d4bDhA60gCebd87lf2PZTf8LL2+h9SLzFDTrgBVg5eC4O8aoQNrgwMMKVvYn+MmK OShurwHXS/7iqCETFaUA7hVtH/NwSWzP7WL5+QIDVOWVGaTLnqdvA4TYSZnljEg2 c02bL2KK+ndsYYshDq7HnVuqr4hIBWKF6y0lApU42mfTCnghX8ZnUMG9pO9K+20X qVfQH58CjOTP0MaHsddyR1sTKKZ1qY1HdoDhnlMVfZD5XqnCMhzefKoMxbxJKmJ3 7hS5w2tNxSx4yYWGj3dXHKhEZi0buA== =ZBi4 -----END PGP SIGNATURE----- Merge tag 'for-6.0/dm-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull more device mapper updates from Mike Snitzer: - Add flags argument to dm_bufio_client_create and introduce DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather than mutex for its locking. - Add optional "try_verify_in_tasklet" feature to DM verity target.

IOMMU Updates for Linux v5.20/v6.0:
Including: - Most intrusive patch is small and changes the default allocation policy for DMA addresses. Before the change the allocator tried its best to find an address in the first 4GB. But that lead to performance problems when that space gets exhaused, and since most devices are capable of 64-bit DMA these days, we changed it to search in the full DMA-mask range from the beginning. This change has the potential to uncover bugs elsewhere, in the kernel or the hardware. There is a Kconfig option and a command line option to restore the old behavior, but none of them is enabled by default. - Add Robin Murphy as reviewer of IOMMU code and maintainer for the dma-iommu and iova code - Chaning IOVA magazine size from 1032 to 1024 bytes to save memory - Some core code cleanups and dead-code removal - Support for ACPI IORT RMR node - Support for multiple PCI domains in the AMD-Vi driver - ARM SMMU changes from Will Deacon: - Add even more Qualcomm device-tree compatible strings - Support dumping of IMP DEF Qualcomm registers on TLB sync timeout - Fix reference count leak on device tree node in Qualcomm driver - Intel VT-d driver updates from Lu Baolu: - Make intel-iommu.h private - Optimize the use of two locks - Extend the driver to support large-scale platforms - Cleanup some dead code - MediaTek IOMMU refactoring and support for TTBR up to 35bit - Basic support for Exynos SysMMU v7 - VirtIO IOMMU driver gets a map/unmap_pages() implementation - Other smaller cleanups and fixes -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAmLs3DIACgkQK/BELZcB GuMizhAAguAnLLOkOLlR9/MhrTZfNXCUX+bfrEIevjFXMw4iPNfCCr4ydQ7EdVK6 ZA/3Z89huYl0d0x/FELolnQi+HOeqYrfTDe4rB7TgNgwZnWa+fdHcyYkgBGyfPaV ilgjNcx8o//9o4NasyB6kU395jVmFxb735gMTTb+tcO9fr+/qIB6hxrHuCklxrNr C7wK6kkoDPi5n0QuXCSjXEx2Hk245pAWKPLwqxsUYzHGlLfl7ULOxw65BUBGvn/H uCsTfJFu7u+ErwQYf0qPuOwRBnRdsx9g5EAnfab8p074SoKWvbNnftIxgIRp8ZEM YgCbhYa1GOFI4r+XzqRzEbc0/vPSttims4Jqz0KxYs7pr5EoVifrWLJFjJdCdc2h Tio1gTvOq8HbH63kwYNKJhg4iSC6zVd37ihEhvfFO6LcgFl4iCfd2o9zK7oY40J4 XoOxofVnJ2e3tzdhZ/n5quCXiudHixm6WuVa7QYKscF7Ud0tY1wWKuibdlMQTeNM 68MvtlteKcfs1BrWzZyrFMrFeAfIY8LI82y6jdJuoNMU5LE9+5yelXBdJhnVygZ+ Jglv1TIt6W/z1H5JgXtNVZ1wWgBm7rurOqNyfN8XCd8eP1z321CLfX8ujkhKrIWP ApG15cwvpnh1JX630+UFiEikTGU0fb2orMdPwYmwuu8DAsoLVHE= =hI2K -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v5.20-or-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: - The most intrusive patch is small and changes the default allocation policy for DMA addresses.

sound updates for 6.0-rc1
As diffstat shows, we've had lots of developments in a wide range at this time; the majority of changes are about ASoC, including subsystem-wide cleanups, continued SOF / Intel updates and a bunch of new drivers (as usual), while there have been some significant (but almost invisible) improvements in ALSA core side, too. Below are some highlights: Core: - Faster lookups of control elements with Xarray; normal user won't notice, but on the devices with tons of control elements, it can be visibly faster - Support for input validation for controls; this will harden for badly written drivers in general with a slight overhead - Deferred async signal handling for working around the potential deadlocks - Cleanup / refactoring raw MIDI locking code ASoC: - Restructing of the set_fmt() callbacks for making things clearer in situations like CODEC to CODEC links - Clean up and modernizing the DAI naming scheme setups - Merge of more of the Intel AVS driver stack, including some board integrations - New version 4 mechanism for communication with SOF DSPs - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms - Improvements for CODEC to CODEC support in the generic cards - Support for AMD Jadeite and various machines, AMD RPL, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780 HD- and USB-audio: - Continued improvement for CS35L41 (sub)codec support - More quirks for various devices (HP, Lenovo, Dell, Clevo) -----BEGIN PGP SIGNATURE----- iQJCBAABCAAsFiEEIXTw5fNLNI7mMiVaLtJE4w1nLE8FAmLr5bcOHHRpd2FpQHN1 c2UuZGUACgkQLtJE4w1nLE93IQ/+OleeiGv7C487QN5MrBCkdFnSAiXsXDArcMgo Gt6XLubH54et1tqi2ms4gRQOqr4HiBelERuqmaCLMZfEgVDc0VhJnf2jjhluYq9+ o9+kcYKul6qTZeNZLPjEX8pBvDe7HzOl7yep++ZnKeH6DAKNQQLDjVuOcQU/BXdY kL8vYrLI3zfqj/pCePb5xpkBx4XdCrE3TfiCr3tAHVg9MyvSGOJyWs02mEBqQRnc rlLmkjQVQyln/AGK4RAPMmrrFytktAvBjmIDyFL7kAzhdxe0ouNzTvdxESeojNJv CVo/p3hl/+0LYjpD2x9v2pQuifOfpjwSCy6f8jsaF366sMwR1D45h051prILsxAF 05D5AOwMCnnJdFQFxw3mIkoDva3/PRX8GFfHsXoz+efc5Ibp8ksNYVgAJ3D2TTtt 7nAYMn0dimVDtw2LHiKantgWAs/rOqD3hDzGxFj2sR662ahsHr8pT8csnJAGoBvW 7kgx7ZzFo/wSyZJqVqV7p4g6J79ScehRwhqoiwZau9Eo+PhuxZUKvm4RwGFh0Vvg GbiVRPfLV4xQd/pDin6qRX1M7cgPc62qGLkhQHAzrX6H5ipwIbQrpyDGLjwdSEp8 XcQmzCG1zGOvb9A8BY1VBOQXxZRTqN58XujbZ6hsms7Uw8sqagxpYLA/e1bvt1E1 RQoHQRw= =1n0/ -----END PGP SIGNATURE----- Merge tag 'sound-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "As the diffstat shows, we've had lots of developments in a wide range at this time; the majority of changes are about ASoC, including subsystem-wide cleanups, continued SOF / Intel updates and a bunch of new drivers (as usual), while there have been some significant (but almost invisible) improvements in ALSA core side, too.

perf tools changes for v6.0: 1st batch
- Introduce 'perf lock contention' subtool, using new lock contention tracepoints and using BPF for in kernel aggregation and then userspace processing using the perf tooling infrastructure for resolving symbols, target specification, etc. Since the new lock contention tracepoints don't provide lock names, get up to 8 stack traces and display the first non-lock function symbol name as a caller: $ perf lock report -F acquired,contended,avg_wait,wait_total Name acquired contended avg wait total wait update_blocked_a... 40 40 3.61 us 144.45 us kernfs_fop_open+... 5 5 3.64 us 18.18 us _nohz_idle_balance 3 3 2.65 us 7.95 us tick_do_update_j... 1 1 6.04 us 6.04 us ep_scan_ready_list 1 1 3.93 us 3.93 us Supports the usual 'perf record' + 'perf report' workflow as well as a BCC/bpftrace like mode where you start the tool and then press control+C to get results: $ sudo perf lock contention -b ^C contended total wait max wait avg wait type caller 42 192.67 us 13.64 us 4.59 us spinlock queue_work_on+0x20 23 85.54 us 10.28 us 3.72 us spinlock worker_thread+0x14a 6 13.92 us 6.51 us 2.32 us mutex kernfs_iop_permission+0x30 3 11.59 us 10.04 us 3.86 us mutex kernfs_dop_revalidate+0x3c 1 7.52 us 7.52 us 7.52 us spinlock kthread+0x115 1 7.24 us 7.24 us 7.24 us rwlock:W sys_epoll_wait+0x148 2 7.08 us 3.99 us 3.54 us spinlock delayed_work_timer_fn+0x1b 1 6.41 us 6.41 us 6.41 us spinlock idle_balance+0xa06 2 2.50 us 1.83 us 1.25 us mutex kernfs_iop_lookup+0x2f 1 1.71 us 1.71 us 1.71 us mutex kernfs_iop_getattr+0x2c ... - Add new 'perf kwork' tool to trace time properties of kernel work (such as softirq, and workqueue), uses eBPF skeletons to collect info in kernel space, aggregating data that then gets processed by the userspace tool, e.g.: # perf kwork report Kwork Name | Cpu | Total Runtime | Count | Max runtime | Max runtime start | Max runtime end | ---------------------------------------------------------------------------------------------------- nvme0q5:130 | 004 | 1.101 ms | 49 | 0.051 ms | 26035.056403 s | 26035.056455 s | amdgpu:162 | 002 | 0.176 ms | 9 | 0.046 ms | 26035.268020 s | 26035.268066 s | nvme0q24:149 | 023 | 0.161 ms | 55 | 0.009 ms | 26035.655280 s | 26035.655288 s | nvme0q20:145 | 019 | 0.090 ms | 33 | 0.014 ms | 26035.939018 s | 26035.939032 s | nvme0q31:156 | 030 | 0.075 ms | 21 | 0.010 ms | 26035.052237 s | 26035.052247 s | nvme0q8:133 | 007 | 0.062 ms | 12 | 0.021 ms | 26035.416840 s | 26035.416861 s | nvme0q6:131 | 005 | 0.054 ms | 22 | 0.010 ms | 26035.199919 s | 26035.199929 s | nvme0q19:144 | 018 | 0.052 ms | 14 | 0.010 ms | 26035.110615 s | 26035.110625 s | nvme0q7:132 | 006 | 0.049 ms | 13 | 0.007 ms | 26035.125180 s | 26035.125187 s | nvme0q18:143 | 017 | 0.033 ms | 14 | 0.007 ms | 26035.169698 s | 26035.169705 s | nvme0q17:142 | 016 | 0.013 ms | 1 | 0.013 ms | 26035.565147 s | 26035.565160 s | enp5s0-rx-0:164 | 006 | 0.004 ms | 4 | 0.002 ms | 26035.928882 s | 26035.928884 s | enp5s0-tx-0:166 | 008 | 0.003 ms | 3 | 0.002 ms | 26035.870923 s | 26035.870925 s | -------------------------------------------------------------------------------------------------------- See commit log messages for more examples with extra options to limit the events time window, etc. - Add support for new AMD IBS (Instruction Based Sampling) features: With the DataSrc extensions, the source of data can be decoded among: - Local L3 or other L1/L2 in CCX. - A peer cache in a near CCX. - Data returned from DRAM. - A peer cache in a far CCX. - DRAM address map with "long latency" bit set. - Data returned from MMIO/Config/PCI/APIC. - Extension Memory (S-Link, GenZ, etc - identified by the CS target and/or address map at DF's choice). - Peer Agent Memory. - Support hardware tracing with Intel PT on guest machines, combining the traces with the ones in the host machine. - Add a "-m" option to 'perf buildid-list' to show kernel and modules build-ids, to display all of the information needed to do external symbolization of kernel stack traces, such as those collected by bpf_get_stackid(). - Add arch TSC frequency information to perf.data file headers. - Handle changes in the binutils disassembler function signatures in perf, bpftool and bpf_jit_disasm (Acked by the bpftool maintainer). - Fix building the perf perl binding with the newest gcc in distros such as fedora rawhide, where some new warnings were breaking the build as perf uses -Werror. - Add 'perf test' entry for branch stack sampling. - Add ARM SPE system wide 'perf test' entry. - Add user space counter reading tests to 'perf test'. - Build with python3 by default, if available. - Add python converter script for the vendor JSON event files. - Update vendor JSON files for alderlake, bonnell, broadwell, broadwellde, broadwellx, cascadelakex, elkhartlake, goldmont, goldmontplus, haswell, haswellx, icelake, icelakex, ivybridge, ivytown, jaketown, knightslanding, nehalemep, nehalemex, sandybridge, sapphirerapids, silvermont, skylake, skylakex, snowridgex, tigerlake, westmereep-dp, westmereep-sp and westmereex. - Add vendor JSON File for Intel meteorlake. - Add Arm Cortex-A78C and X1C JSON vendor event files. - Add workaround to symbol address reading from ELF files without phdr, falling back to the previoous equation. - Convert legacy map definition to BTF-defined in the perf BPF script test. - Rework prologue generation code to stop using libbpf deprecated APIs. - Add default hybrid events for 'perf stat' on x86. -

Introduce 'perf lock contention' subtool, using new lock contention tracepoints and using BPF for in kernel aggregation and then userspace processing using the perf tooling infrastructure for resolving symbols, target specification, etc. Since the new lock contention tracepoints don't provide lock names, get up to 8 stack traces and display the first non-lock function symbol name as a caller: $ perf lock report -F acquired,contended,avg_wait,wait_total Name acquired contended avg wait total wait update_blocked_a... 40 40 3.61 us 144.45 us kernfs_fop_open+... 5 5 3.64 us 18.18 us _nohz_idle_balance 3 3 2.65 us 7.95 us tick_do_update_j... 1 1 6.04 us 6.04 us ep_scan_ready_list 1 1 3.93 us 3.93 us Supports the usual 'perf record' + 'perf report' workflow as well as a BCC/bpftrace like mode where you start the tool and then press control+C to get results: $ sudo perf lock contention -b ^C contended total wait max wait avg wait type caller 42 192.67 us 13.64 us 4.59 us spinlock queue_work_on+0x20 23 85.54 us 10.28 us 3.72 us spinlock worker_thread+0x14a 6 13.92 us 6.51 us 2.32 us mutex kernfs_iop_permission+0x30 3 11.59 us 10.04 us 3.86 us mutex kernfs_dop_revalidate+0x3c 1 7.52 us 7.52 us 7.52 us spinlock kthread+0x115 1 7.24 us 7.24 us 7.24 us rwlock:W sys_epoll_wait+0x148 2 7.08 us 3.99 us 3.54 us spinlock delayed_work_timer_fn+0x1b 1 6.41 us 6.41 us 6.41 us spinlock idle_balance+0xa06 2 2.50 us 1.83 us 1.25 us mutex kernfs_iop_lookup+0x2f 1 1.71 us 1.71 us 1.71 us mutex kernfs_iop_getattr+0x2c ... - Add new 'perf kwork' tool to trace time properties of kernel work (such as softirq, and workqueue), uses eBPF skeletons to collect info in kernel space, aggregating data that then gets processed by the userspace tool, e.g.: # perf kwork report Kwork Name | Cpu | Total Runtime | Count | Max runtime | Max runtime start | Max runtime end | ---------------------------------------------------------------------------------------------------- nvme0q5:130 | 004 | 1.101 ms | 49 | 0.051 ms | 26035.056403 s | 26035.056455 s | amdgpu:162 | 002 | 0.176 ms | 9 | 0.046 ms | 26035.268020 s | 26035.268066 s | nvme0q24:149 | 023 | 0.161 ms | 55 | 0.009 ms | 26035.655280 s | 26035.655288 s | nvme0q20:145 | 019 | 0.090 ms | 33 | 0.014 ms | 26035.939018 s | 26035.939032 s | nvme0q31:156 | 030 | 0.075 ms | 21 | 0.010 ms | 26035.052237 s | 26035.052247 s | nvme0q8:133 | 007 | 0.062 ms | 12 | 0.021 ms | 26035.416840 s | 26035.416861 s | nvme0q6:131 | 005 | 0.054 ms | 22 | 0.010 ms | 26035.199919 s | 26035.199929 s | nvme0q19:144 | 018 | 0.052 ms | 14 | 0.010 ms | 26035.110615 s | 26035.110625 s | nvme0q7:132 | 006 | 0.049 ms | 13 | 0.007 ms | 26035.125180 s | 26035.125187 s | nvme0q18:143 | 017 | 0.033 ms | 14 | 0.007 ms | 26035.169698 s | 26035.169705 s | nvme0q17:142 | 016 | 0.013 ms | 1 | 0.013 ms | 26035.565147 s | 26035.565160 s | enp5s0-rx-0:164 | 006 | 0.004 ms | 4 | 0.002 ms | 26035.928882 s | 26035.928884 s | enp5s0-tx-0:166 | 008 | 0.003 ms | 3 | 0.002 ms | 26035.870923 s | 26035.870925 s | -------------------------------------------------------------------------------------------------------- See commit log messages for more examples with extra options to limit the events time window, etc. -

OpenRISC fixes for 5.20-rc1/6.0
In this cycle we add PCI support to OpenRISC used in our new QEMU virt platform. The base of this series is a merge of Bjorn's PCI headers cleanup branch and 5.16-rc6. The patches from the PCI branch are needed for the series to work. The main updates from me include: - Kconfig updates to support OpenRISC PCI (just config now after the PCI cleanups I did on Bjorn's branch) - A new defconfig for the qemu virt platform. - Also there is one MAINTAINERS update. As I was working on the PCI series we kept getting bounces from Richard's old email address. I added this here; I am not sure how these are usually handled when the maintainer doesn't queue it themselves. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE2cRzVK74bBA6Je/xw7McLV5mJ+QFAmLtfRwACgkQw7McLV5m J+Tf0w//dJaiBa4kYysJ78vlH69ZGjaJMJfomF5HQVhF0sF5h5yUAaYqNHgItRwG 76vewFESEJZ+fwxfLWdOKkCqQSkCG5bJkE5SCLViu9B4Cu+lbUZyzX2CwpcZz6ab rYnSolteMC4oL1MUFWXt1yP9ZUiTmAKN86uTfO+2ufax5WE/B0hS7m830bIOyqdZ qFnr1Mv0ujqUx1Oz8PDsy6jjV5AVBZP8zcEVGX+n9n3RpB8kUD9Zl+Rs3/AgfXdx aoOCcAS0hfYGfzkx6gGKtAiKwRicXNKYTPkGZagrKHppuv6jTAjE9v8W7VRCYdD5 JlmeVRjw8Zl4ALVzJINXlejymzZmNz3D3ajFkTm4AkHh/F0yq1hOPGY4Jr7s8hj/ vioK2i3GWxfbN5sUZkKxKT3BCAGkAoNZMGsXHjURhIIvJ8Yrjp4DtwLdcLn6btgr KyVlUGteD4TLK4Uib+tQKmYpv/6uGa6LFSIEoYhcq2URvJsCzLOvXdpdYtj/90jA LezVX2Csu9uilYmXSqkNeTn3kGBEJpHlbI4N8oQ6stBBllpiwsOOSxoGQiiARbeO Af3GjzFG71aEKkF5ktBijpecdGZys/bpTwA1AELY8C3h9ekzBg8LtEigCyXRurNF Pnpj2JJvkG4q5moH+DQmQC4109NeZ+7ysnlZEoPyRFx9oUQu6ng= =t80+ -----END PGP SIGNATURE----- Merge tag 'for-linus' of github.com:openrisc/linux Pull OpenRISC updates from Stafford Horne: "In this cycle we add PCI support to OpenRISC used in our new QEMU virt platform.

asm-generic: updates for 6.0
There are three independent sets of changes: - Sai Prakash Ranjan adds tracing support to the asm-generic version of the MMIO accessors, which is intended to help understand problems with device drivers and has been part of Qualcomm's vendor kernels for many years. - A patch from Sebastian Siewior to rework the handling of IRQ stacks in softirqs across architectures, which is needed for enabling PREEMPT_RT. - The last patch to remove the CONFIG_VIRT_TO_BUS option and some of the code behind that, after the last users of this old interface made it in through the netdev, scsi, media and staging trees. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmLqPPEACgkQmmx57+YA GNlUbQ/+NpIsiA0JUrCGtySt8KrLHdA2dH9lJOR5/iuxfphscPFfWtpcPvcXQWmt a8u7wyI8SHW1ku4U0Y5sO0dBSldDnoIqJ5t4X5d7YNU9yVtEtucqQhZf+GkrPlVD 1HkRu05B7y0k2BMn7BLhSvkpafs3f1lNGXjs8oFBdOF1/zwp/GjcrfCK7KFzqjwU dYrX0SOFlKFd4BZC75VfK+XcKg4LtwIOmJraRRl7alz2Q5Oop2hgjgZxXDPf//vn SPOhXJN/97i1FUpY2TkfHVH1NxbPfjCV4pUnjmLG0Y4NSy9UQ/ZcXHcywIdeuhfa 0LySOIsAqBeccpYYYdg2ubiMDZOXkBfANu/sB9o/EhoHfB4svrbPRDhBIQZMFXJr MJYu+IYce2rvydA/nydo4q++pxR8v1ES1ZIo8bDux+q1CI/zbpQV+f98kPVRA0M7 ajc+5GTIqNIsvHzzadq7eYxcj5Bi8Li2JA9sVkAQ+6iq1TVyeYayMc9eYwONlmqw MD+PFYc651pKtXZCfkLXPIKSwS0uPqBndAibuVhpZ0hxWaCBBdKvY9mrWcPxt0kA tMR8lrosbbrV2K48BFdWTOHvCs2FhHQxPGVPZ/iWuxTA0hHZ9tUlaEkSX+VM57IU KCYQLdWzT8J9vrgqSbgYKlb6pSPz6FIjTfut6NZMmshIbavHV/Q= =aTR0 -----END PGP SIGNATURE----- Merge tag 'asm-generic-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "There are three independent sets of changes: - Sai Prakash Ranjan adds tracing support to the asm-generic version of the MMIO accessors, which is intended to help understand problems with device drivers and has been part of Qualcomm's vendor kernels for many years - A patch from Sebastian Siewior to rework the handling of IRQ stacks in softirqs across architectures, which is needed for enabling PREEMPT_RT - The last patch to remove the CONFIG_VIRT_TO_BUS option and some of the code behind that, after the last users of this old interface made it in through the netdev, scsi, media and staging trees" * tag 'asm-generic-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: uapi: asm-generic: fcntl: Fix typo 'the the' in comment arch/*/: remove CONFIG_VIRT_TO_BUS soc: qcom: geni: Disable MMIO tracing for GENI SE serial: qcom_geni_serial: Disable MMIO tracing for geni serial asm-generic/io: Add logging support for MMIO accessors KVM: arm64: Add a flag to disable MMIO trace for nVHE KVM lib: Add register read/write tracing support drm/meson: Fix overflow implicit truncation warnings irqchip/tegra: Fix overflow implicit truncation warnings coresight: etm4x: Use asm-generic IO memory barriers arm64: io: Use asm-generic high level MMIO accessors arch/*: Disable softirq stacks on PREEMPT_RT. |

Tracing updates for 5.20 / 6.0
- Runtime verification infrastructure This is the biggest change for this pull request. It introduces the runtime verification that is necessary for running Linux on safety critical systems. It allows for deterministic automata models to be inserted into the kernel that will attach to tracepoints, where the information on these tracepoints will move the model from state to state. If a state is encountered that does not belong to the model, it will then activate a given reactor, that could just inform the user or even panic the kernel (for which safety critical systems will detect and can recover from). - Two monitor models are also added: Wakeup In Preemptive (WIP - not to be confused with "work in progress"), and Wakeup While Not Running (WWNR). - Added __vstring() helper to the TRACE_EVENT() macro to replace several vsnprintf() usages that were all doing it wrong. - eprobes now can have their event autogenerated when the event name is left off. - The rest is various cleanups and fixes. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYu0yzRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qj4HAP4tQtV55rjj4DQ5XIXmtI3/64PmyRSJ +y4DEXi1UvEUCQD/QAuQfWoT/7gh35ltkfeS4t3ockzy14rrkP5drZigiQA= =kEtM -----END PGP SIGNATURE----- Merge tag 'trace-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - Runtime verification infrastructure This is the biggest change here.

New code for 5.20:
- Improve scalability of the XFS log by removing spinlocks and global synchronization points. - Add security labels to whiteout inodes to match the other filesystems. - Clean up per-ag pointer passing to simplify call sites. - Reduce verifier overhead by precalculating more AG geometry. - Implement fast-path lockless lookups in the buffer cache to reduce spinlock hammering. - Make attr forks a permanent part of the inode structure to fix a UAF bug and because most files these days tend to have security labels and soon will have parent pointers too. - Clean up XFS_IFORK_Q usage and give it a better name. - Fix more UAF bugs in the xattr code. - SOB my tags. - Fix some typos in the timestamp range documentation. - Fix a few more memory leaks. - Code cleanups and typo fixes. - Fix an unlocked inode fork pointer access in getbmap.

SCSI misc on 20220804
Updates to the usual drivers (ufs, qla2xx, target, lpfc, smartpqi, mpi3mr). The main driver change that might cause issues on down the road is the conversion of some of our oldest surviving drivers to the DMA API (should only affect m68k). The only major core change is the rework of async resume; the rest are either completely trivial or for updating deprecated APIs. Signed-off-by: James E.J.
