Pull ptrace_stop cleanups from Eric Biederman:
"While looking at the ptrace problems with PREEMPT_RT and the problems
Peter Zijlstra was encountering with ptrace in his freezer rewrite I
identified some cleanups to ptrace_stop that make sense on their own
and move make resolving the other problems much simpler.
The biggest issue is the habit of the ptrace code to change
task->__state from the tracer to suppress TASK_WAKEKILL from waking up
the tracee. No other code in the kernel does that and it is straight
forward to update signal_wake_up and friends to make that unnecessary.
Peter's task freezer sets frozen tasks to a new state TASK_FROZEN and
then it stores them by calling "wake_up_state(t, TASK_FROZEN)" relying
on the fact that all stopped states except the special stop states can
tolerate spurious wake up and recover their state.
The state of stopped and traced tasked is changed to be stored in
task->jobctl as well as in task->__state. This makes it possible for
the freezer to recover tasks in these special states, as well as
serving as a general cleanup. With a little more work in that
direction I believe TASK_STOPPED can learn to tolerate spurious wake
ups and become an ordinary stop state.
The TASK_TRACED state has to remain a special state as the registers
for a process are only reliably available when the process is stopped
in the scheduler. Fundamentally ptrace needs acess to the saved
register values of a task.
There are bunch of semi-random ptrace related cleanups that were found
while looking at these issues.
One cleanup that deserves to be called out is from commit 57b6de08b5f6
("ptrace: Admit ptrace_stop can generate spuriuos SIGTRAPs"). This
makes a change that is technically user space visible, in the handling
of what happens to a tracee when a tracer dies unexpectedly. According
to our testing and our understanding of userspace nothing cares that
spurious SIGTRAPs can be generated in that case"

Pull kthread updates from Eric Biederman:
"This updates init and user mode helper tasks to be ordinary user mode
tasks.
Commit 40966e316f86 ("kthread: Ensure struct kthread is present for
all kthreads") caused init and the user mode helper threads that call
kernel_execve to have struct kthread allocated for them. This struct
kthread going away during execve in turned made a use after free of
struct kthread possible.
Here, commit 343f4c49f243 ("kthread: Don't allocate kthread_struct for
init and umh") is enough to fix the use after free and is simple
enough to be backportable.
The rest of the changes pass struct kernel_clone_args to clean things
up and cause the code to make sense.
In making init and the user mode helpers tasks purely user mode tasks
I ran into two complications. The function task_tick_numa was
detecting tasks without an mm by testing for the presence of
PF_KTHREAD. The initramfs code in populate_initrd_image was using
flush_delayed_fput to ensuere the closing of all it's file descriptors
was complete, and flush_delayed_fput does not work in a userspace
thread.
I have looked and looked and more complications and in my code review
I have not found any, and neither has anyone else with the code
sitting in linux-next"

Pull ipc sysctl namespace updates from Eric Biederman:
"This updates the ipc sysctls so that they are fundamentally per ipc
namespace. Previously these sysctls depended upon a hack to simulate
being per ipc namespace by looking up the ipc namespace in read or
write. With this set of changes the ipc sysctls are registered per ipc
namespace and open looks up the ipc namespace.
Not only does this series of changes ensure the traditional binding at
open time happens, but it sets a foundation for being able to relax
the permission checks to allow a user namspace root to change the ipc
sysctls for an ipc namespace that the user namespace root requires. To
do this requires the ipc namespace to be known at open time"

Commit 23cfbc6ec44e ("firmware: Add the support for ZSTD-compressed
firmware files") added support for ZSTD compression, but in the process
also made the previously default XZ compression a config option.
That means that anybody who upgrades their kernel and does a
make oldconfig
to update their configuration, will end up without the XZ compression
that the configuration used to have.
Add the 'default y' to make sure this doesn't happen.
The whole compression question should probably be improved upon, since
it is now possible to "enable" compression in the kernel config but not
enable any actual compression algorithm, which makes it all very
useless. It makes no sense to ask Kconfig questions that enable
situations that are nonsensical like that.
This at least fixes the immediate problem of a kernel update resulting
in a nonbootable machine because of a missed option.

tc_redirect_dtime was reported flaky from time to time. It
always fails at the udp test and complains about the bpf@tc-ingress
got a skb->tstamp when handling udp packet. It is unexpected
because the skb->tstamp should have been cleared when crossing
different netns.
The most likely cause is that the skb is actually a tcp packet
from the earlier tcp test. It could be the final TCP_FIN handling.
This patch tightens the skb->tstamp check in the bpf prog. It ensures
the skb is the current testing traffic. First, it checks that skb
matches the IPPROTO of the running test (i.e. tcp vs udp).
Second, it checks the server port (dst_ns_port). The server
port is unique for each test (50000 + test_enum).
Also fixed a typo in test_udp_dtime(): s/P100/P101/

Pull initial Loongarch architecture code from Arnd Bergmann:
"This is the majority of the loongarch architecture code, including the
final system call interface and all core functionality.
It still misses three sets of peripheral but vital patches to add
support for other subsystems, which have yet to pass review:
- The drivers/firmware/efi stub for booting from a standard UEFI
firmware implementation. Both the original custom boot interface
and a draft implementation of the EFI stub did not make it, so it
is currently impossible to boot the kernel, until the loongarch
specific portions get accepted into the UEFI subsystem
- The drivers/irqchip/irq-loongson-*.c drivers are shared with the
the MIPS port, but currently lack support for ACPI based booting,
which will get merged through the irqchip subsystem.
- Similarly, the drivers/pci/controller/pci-loongson.c needs to be
modified for ACPI support, which will be merged through the PCI
subsystem.
While the port cannot actually be used before all the above are
merged, having it in 5.19 helps to establish the user space ABI for
the libc ports to build on, and to help any treewide changes in the
mainline kernel get applied here as well.
A gcc-12 based tool chains for build testing is now included in
https://mirrors.edge.kernel.org/pub/tools/crosstool/"
Original description from Huacai Chen:
"LoongArch is a new RISC ISA, which is a bit like MIPS or RISC-V.
LoongArch includes a reduced 32-bit version (LA32R), a standard 32-bit
version (LA32S) and a 64-bit version (LA64). LoongArch use ACPI as its
boot protocol LoongArch-specific interrupt controllers (similar to APIC)
are already added in the next revision of ACPI Specification (current
revision is 6.4).

cmd header to align w/ the up-to-date DMUB FW for PSR-SU support.
[how]
Add definitions and items below into dmub cmd header:
- DMUB psr version enumeration for PSR-SU
- dirty rectangle structure
- psr debug flag of forcing full frame update
- dmub command of updating dirty rectangle and cursor infor
- dmub psr command type of setting sink vtotal in PSR active
- dmub psr su debug flags structure
- dmub cmd structure for
- updating dirty rectangle
- cursor infor
- setting sink vtotal
- dmub ringbuffer command items

Revised validation logic when marking for seamless boot. Init resources
accordingly when Pre-OS has ODM enabled. Reset ODM when transitioning
Pre-OS odm to Post-OS non-odm to avoid corruption. Apply logic to set
odm accordingly upon commit.

[WHY & HOW]
Implements DTB ref clock switching with reg key default to OFF.
Refactors dccg DTBCLK logic to not store redundant state information
dccg. Also removes duplicated functions that should be inherited from
other dcn versions.

[Why]
Previously we used to send FCLK P-state enable messages upon each call
to update_clocks based on dml output. This resulted in increased message
transactions between DC and PMFW.
[How]
Update the code to check safe_to_lower status and send the message based
on dml input only on boot. This reduces message transactions. Also
remove other unwanted code based on current code status.

[why]
DCN has sidebands to control some clocks, it is useful for clk_mgr to
always update the clocks it explicitly controls rather than skip them
because it enables more configurations to work without SMU
[how]
only skip handling clocks where SMU manages the frequency for clocks
with DENTIST sideband (DISP/DPP), only skip the voltage request when SMU
not available, but otherwise proceed normally

[Why]
HUBP_UNBOUNDED_REQ_MODE and CURSOR_REQ_MODE are normally set together.
In hubp32_prepare_subvp_buffering() call, CURSOR_REQ_MODE is set based on
whether SubVP is enabled or not. For non MPO case, both REQ_MODE
registers are set to 1. But since SubVP is not enabled, then
CURSOR_REQ_MODE is set to 0, overriding the previous value.
[How]
Do not set CURSOR_REQ_MODE to 0 if SubVP is not enabled. This
will allow CURSOR_REQ_MODE to stay as 1 in the non MPO case.
Add note to follow up and check case for single pipe MPO and
SubVP enabled as this would cause both REQ_MODE registers to be
set to 0 but SubVP enabled would override CURSOR_REQ_MODE to 1.
