In the remoteproc core, it's now possible to mark the sysfs attributes
read only on a per-instance basis, which is then used by the TI wkup M3
driver. The rproc_shutdown() interface propagates errors to the caller
and an array underflow is fixed in the debugfs interface. The
rproc_da_to_va() API is moved to the public API to allow e.g. child
rpmsg devices to acquire pointers to memory shared with the remote
processor.
The TI K3 R5F and DSP drivers gains support for attaching to instances
already started by the bootloader, aka IPC-only mode.
The Mediatek remoteproc driver gains support for the MT8186 SCP. The
driver's probe function is reordered and moved to use the devres version
of rproc_alloc() to save a few gotos. The driver's probe function is
also transitioned to use dev_err_probe() to provide better debug
support.
Support for the Qualcomm SC7280 Wireless Subsystem (WPSS) is introduced.
The Hexagon based remoteproc drivers gains support for voting for
interconnect bandwidth during launch of the remote processor. The modem
subsystem (MSS) driver gains support for probing the BAM-DMUX
driver, which provides the network interface towards the modem on a set
of older Qualcomm platforms.
In addition a number a bug fixes are introduces in the Qualcomm drivers.
Lastly Qualcomm ADSP DeviceTree binding is converted to YAML format, to
allow validation of DeviceTree source files.

The major part of the rpmsg changes for v5.18 relates to improvements in
the rpmsg char driver, which now allow automatically attaching to rpmsg
channels as well as initiating new communication channels from the Linux
side.
The SMD driver is moved to arch_initcall with the purpose of registering
root clocks earlier during boot. Also in the SMD driver, a workaround
for the resource power management (RPM) channel is introduced to resolve
an issue where both the RPM and Linux side waits for the other to close
the communication established by the bootloader - this unblocks support
for clocks and regulators on some older Qualcomm platforms.

clk_set_rate_range() works so that the frequency is re-evaulated each time the
rate is changed. Previously we wouldn't let clk providers see a rate that was
different if it was still within the range, which could be bad for power if the
clk could run slower when a range expands. Now the clk provider can decide to
do something differently when the constraints change. This broke Nvidia's clk
driver so we had to wait for the fix for that to bake a little more in -next.
The rate range patch series also introduced a kunit suite for the clk framework
that we're going to extend in the next release. It already made it easy to find
corner cases in the rate range patches so I'm excited to see it cover more clk
code and increase our confidence in core framework patches in the future. I
also added a kunit test for the basic clk gate code and that work will continue
to cover more basic clk types: muxes, dividers, etc.
Beyond the core code we have the usual set of clk driver updates and additions.
Qualcomm again dominates the diffstat here with lots more SoCs being supported
and i.MX follows afer that with a similar number of SoCs gaining clk drivers.
Beyond those large additions there's drivers being modernized to use
clk_parent_data so we can move away from global string names for all the clks
in an SoC. Finally there's lots of little fixes all over the clk drivers for
typos, warnings, and missing clks that aren't critical and get batched up
waiting for the next merge window to open. Nothing super big stands out in the
driver pile. Full details are below.
Core:
- Make clk_set_rate_range() re-evaluate the limits each time
- Introduce various clk_set_rate_range() tests

Jason Donenfeld reports that my commit 1c24a186398f ("fs: fd tables have
to be multiples of BITS_PER_LONG") doesn't work, and the reason is an
embarrassing brown-paper-bag bug.
Yes, we want to align the number of fds to BITS_PER_LONG, and yes, the
reason they might not be aligned is because the incoming 'max_fd'
argument might not be aligned.
But aligining the argument - while simple - will cause a "infinitely
big" maxfd (eg NR_OPEN_MAX) to just overflow to zero. Which most
definitely isn't what we want either.
The obvious fix was always just to do the alignment last, but I had
moved it earlier just to make the patch smaller and the code look
simpler. Duh. It certainly made _me_ look simple.

This has always been the rule: fdtables have several bitmaps in them,
and as a result they have to be sized properly for bitmaps. We walk
those bitmaps in chunks of 'unsigned long' in serveral cases, but even
when we don't, we use the regular kernel bitops that are defined to work
on arrays of 'unsigned long', not on some byte array.
Now, the distinction between arrays of bytes and 'unsigned long'
normally only really ends up being noticeable on big-endian systems, but
Fedor Pchelkin and Alexey Khoroshilov reported that copy_fd_bitmaps()
could be called with an argument that wasn't even a multiple of
BITS_PER_BYTE. And then it fails to do the proper copy even on
little-endian machines.
The bug wasn't in copy_fd_bitmap(), but in sane_fdtable_size(), which
didn't actually sanitize the fdtable size sufficiently, and never made
sure it had the proper BITS_PER_LONG alignment.
That's partly because the alignment historically came not from having to
explicitly align things, but simply from previous fdtable sizes, and
from count_open_files(), which counts the file descriptors by walking
them one 'unsigned long' word at a time and thus naturally ends up doing
sizing in the proper 'chunks of unsigned long'.
But with the introduction of close_range(), we now have an external
source of "this is how many files we want to have", and so
sane_fdtable_size() needs to do a better job.
This also adds that explicit alignment to alloc_fdtable(), although
there it is mainly just for documentation at a source code level. The
arithmetic we do there to pick a reasonable fdtable size already aligns
the result sufficiently.
In fact,clang notices that the added ALIGN() in that function doesn't
actually do anything, and does not generate any extra code for it.
It turns out that gcc ends up confusing itself by combining a previous
constant-sized shift operation with the variable-sized shift operations
in roundup_pow_of_two(). And probably due to that doesn't notice that
the ALIGN() is a no-op. But that's a (tiny) gcc misfeature that doesn't
matter. Having the explicit alignment makes sense, and would actually
matter on a 128-bit architecture if we ever go there.
This also adds big comments above both functions about how fdtable sizes
have to have that BITS_PER_LONG alignment.

Freescale Layerscape Lynx 28G SerDes PHYs are only present on
Freescale/NXP Layerscape SoCs.
Move PHY_FSL_LYNX_28G outside the block for ARCH_MXC, as the latter
is meant for i.MX8 SoCs, which is a different family than Layerscape.
Add a dependency on ARCH_LAYERSCAPE, to prevent asking the user about
this driver when configuring a kernel without Layerscape SoC support.

'dma-ranges' in the example is written for cell sizes of 2 cells, but
the schema and example specify sizes of 1 cell. As the h/w has a bus
address of >32-bits, cell sizes of 2 is correct. Update the schema's
'#address-cells' and '#size-cells' to be 2 and adjust the example
throughout.
There's no error currently because dtc only checks 'dma-ranges' is a
correct multiple number of cells (3) and the schema checking is based on
bracketing of entries.

To avoid failure of dt_binding_check perform a slight refactoring
of the examples: the main block is kept, but that required fixing
the address and size cells, plus the inclusion of missing dt-bindings
headers, required to parse some of the values assigned to various
properties.

This set of changes removes tracehook.h, moves modification of all of
the ptrace fields inside of siglock to remove races, adds a missing
permission check to ptrace.c
The removal of tracehook.h is quite significant as it has been a major
source of confusion in recent years. Much of that confusion was
around task_work and TIF_NOTIFY_SIGNAL (which I have now decoupled
making the semantics clearer).
For people who don't know tracehook.h is a vestiage of an attempt to
implement uprobes like functionality that was never fully merged, and
was later superseeded by uprobes when uprobes was merged. For many
years now we have been removing what tracehook functionaly a little
bit at a time. To the point where now anything left in tracehook.h is
some weird strange thing that is difficult to understand.
Eric W. Biederman (15):
ptrace: Move ptrace_report_syscall into ptrace.h
ptrace/arm: Rename tracehook_report_syscall report_syscall
ptrace: Create ptrace_report_syscall_{entry,exit} in ptrace.h
ptrace: Remove arch_syscall_{enter,exit}_tracehook
ptrace: Remove tracehook_signal_handler
task_work: Remove unnecessary include from posix_timers.h
task_work: Introduce task_work_pending
task_work: Call tracehook_notify_signal from get_signal on all architectures
task_work: Decouple TIF_NOTIFY_SIGNAL and task_work
signal: Move set_notify_signal and clear_notify_signal into sched/signal.h
resume_user_mode: Remove #ifdef TIF_NOTIFY_RESUME in set_notify_resume
resume_user_mode: Move to resume_user_mode.h
tracehook: Remove tracehook.h
ptrace: Move setting/clearing ptrace_message into ptrace_stop
ptrace: Return the signal to continue with from ptrace_stop
Jann Horn (1):
ptrace: Check PTRACE_O_SUSPEND_SECCOMP permission on PTRACE_SEIZE

The current autocork algorithms will delay the data transmission
in BH context to smc_release_cb() when sock_lock is hold by user.
So there is a possibility that when connection is being actively
closed (sock_lock is hold by user now), some corked data still
remains in sndbuf, waiting to be sent by smc_release_cb(). This
will cause:
- smc_close_stream_wait(), which is called under the sock_lock,
has a high probability of timeout because data transmission is
delayed until sock_lock is released.
- Unexpected data sends may happen after connction closed and use
the rtoken which has been deleted by remote peer through
LLC_DELETE_RKEY messages.
So this patch will try to send out the remaining corked data in
sndbuf before active close process, to ensure data integrity and
avoid unexpected data transmission after close.

Only a single patch this cycle. Fix an obvious mistake with the
kdb memory accessors. It was a stupid mistake (to/from backwards)
but it has been there for a long time since many architectures
tolerated it with surprisingly good grace.

The bug is here:
return rule;
The list iterator value 'rule' will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the
iterator value will be NULL if the list is empty or no element
is found.
To fix the bug, return 'rule' when found, otherwise return NULL.

cc1: all warnings being treated as errors
This is due to the function ptp_find_pin() returning a pin ID of -1 when
a valid pin is not found and this error never being checked.
Change the TSIO_PIN_VALID() function to also check that a pin ID is not
negative and use this macro in bnxt_ptp_enable() to check the result of
the calls to ptp_find_pin() to return an error early for invalid pins.
This fixes the compilation error.

Here are the big set of tty and serial driver changes for 5.18-rc1.
Nothing major, some more good cleanups from Jiri and 2 new serial
drivers. Highlights include:
- termbits cleanups
- export symbol cleanups and other core cleanups from Jiri Slaby
- new sunplus and mvebu uart drivers (amazing that people are
still creating new uarts...)
- samsung serial driver cleanups
- ldisc 29 is now "reserved" for experimental/development line
disciplines
- lots of other tiny fixes and cleanups to serial drivers and
bindings
All of these have been in linux-next for a while with no reported
issues.
