riscv:uprobe fix SR_SPIE set/clear handling
In riscv the process of uprobe going to clear spie before exec
the origin insn,and set spie after that.But When access the page
which origin insn has been placed a page fault may happen and
irq was disabled in arch_uprobe_pre_xol function,It cause a WARN
as follows.
There is no need to clear/set spie in arch_uprobe_pre/post/abort_xol.
We can just remove it.

dt-bindings: riscv: fix SiFive l2-cache's cache-sets
Fix device tree schema validation error messages for the SiFive
Unmatched: ' cache-sets:0:0: 1024 was expected'.
The existing bindings allow for just 1024 cache-sets but the fu740 on
Unmatched the has 2048 cache-sets. The ISA itself permits any arbitrary
power of two, however this is not supported by dt-schema. The RTL for
the IP, to which the number of cache-sets is a tunable parameter, has
been released publicly so speculatively adding a small number of
"reasonable" values seems unwise also.
Instead, as the binding only supports two distinct controllers: add 2048
and explicitly lock it to the fu740's l2 cache while limiting 1024 to
the l2 cache on the fu540.

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() |

- 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.

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

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.
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

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)

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

- 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.

- 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.

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.

Merge tag 'perf-tools-for-v6.0-2022-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tools updates from Arnaldo Carvalho de Melo:
- 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

"Most of the MM queue. A few things are still pending.
Liam's maple tree rework didn't make it. This has resulted in a few
other minor patch series being held over for next time.
Multi-gen LRU still isn't merged as we were waiting for mapletree to
stabilize. The current plan is to merge MGLRU into -mm soon and to
later reintroduce mapletree, with a view to hopefully getting both
into 6.1-rc1.

* Fix deadlock in sm_ftl
* Various refcount fixes in maps, partitions and parser code
* Integer overflow fixes in mtdchar
* Support for Sercomm partitions
NAND driver changes:
* Clockrate fix for arasan
* Add ATO25D1GA support
* Double free fix for meson driver
* Fix probe/remove methods in cafe NAND
* Support unprotected spare data pages in qcom_nandc
SPI NOR core changes:
* move SECT_4K_PMC flag out of the core as it's a vendor specific flag
* s/addr_width/addr_nbytes: address width means the number of IO lines
used for the address, whereas in the code it is used as the number of
address bytes.
* do not change nor->addr_nbytes at SFDP parsing time. At the SFDP parsing
time we should not change members of struct spi_nor, but instead fill
members of struct spi_nor_flash_parameters which could later on be used
by the callers.
* track flash's internal address mode so that we can use 4B opcodes
together with opcodes that don't have a 4B opcode correspondent.
SPI NOR manufacturer drivers changes:
* esmt: Rename "f25l32qa" flash name to "f25l32qa-2s".
* micron-st: Skip FSR reading if SPI controller does not support it to
allow flashes that support FSR to work even when attached to such SPI
controllers.
* spansion: Add s25hl-t/s25hs-t IDs and fixups.

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.

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.

ARM: SoC: late updates for 6.0
These updates came in after I had already tagged the branches,
but they still seem appropriate for 6.0 and most of them were
part of linux-next through other trees.
- The reset controller tree adds one new driver for the TI TPS380x
power management chip and a few minor changes in other drivers
- Apple M1 now has a DT entry for the NVMe controller after the
driver was merged, and has a new mailing list in the MAINTAINERS
file.
- Fixes for USB on the Socionext Uniphier platforms and the
network controller on Intel Cyclone5.

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.

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.

Merge tag 'xfs-5.20-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"The biggest changes for this release are the log scalability
improvements, lockless lookups for the buffer cache, and making the
attr fork a permanent part of the incore inode in preparation for
directory parent pointers.
There's also a bunch of bug fixes that have accumulated since -rc5. I
might send you a second pull request with some more bug fixes that I'm
still working on.
Once the merge window ends, I will hand maintainership back to Dave
Chinner until the 6.1-rc1 release so that I can conduct the design
review for the online fsck feature, and try to get it merged.
Summary:
- 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.
