The current QMP UFS PHY bindings are based on the original MSM8996 PCIe
PHY binding which provided multiple PHYs per IP block and these in turn
were described by child nodes.
The QMP UFS PHY block only provide a single PHY and the remnant child
node does not really reflect the hardware.
The original MSM8996 binding also ended up describing the individual
register blocks as belonging to either the wrapper node or the PHY child
nodes.
This is an unnecessary level of detail which has lead to problems when
later IP blocks using different register layouts have been forced to fit
the original mould rather than updating the binding. The bindings are
arguable also incomplete as they only the describe register blocks used
by the current Linux drivers.
Add a new binding for the UFS QMP PHYs found on SC8280XP which further
bindings can be based on.
Note that the current binding is simply removed instead of being
deprecated as it was only recently merged and support for SC8280XP is
still under development.

In preparation for adding new bindings for SC8280XP which further

add a reference to the SC8280XP bindings.

Add i.MX8MP PCIe PHY binding.
On i.MX8MM, the initialized default value of PERST bit(BIT3) of
SRC_PCIEPHY_RCR is 1b'1.
But i.MX8MP has one inversed default value 1b'0 of PERST bit.
And the PERST bit should be kept 1b'1 after power and clocks are stable.
So add one more PERST explicitly for i.MX8MP PCIe PHY.

Pull more random number generator updates from Jason Donenfeld:
"This time with some large scale treewide cleanups.
The intent of this pull is to clean up the way callers fetch random
integers. The current rules for doing this right are:
- If you want a secure or an insecure random u64, use get_random_u64()
- If you want a secure or an insecure random u32, use get_random_u32()
The old function prandom_u32() has been deprecated for a while
now and is just a wrapper around get_random_u32(). Same for
get_random_int().
- If you want a secure or an insecure random u16, use get_random_u16()
- If you want a secure or an insecure random u8, use get_random_u8()
- If you want secure or insecure random bytes, use get_random_bytes().
The old function prandom_bytes() has been deprecated for a while
now and has long been a wrapper around get_random_bytes()
- If you want a non-uniform random u32, u16, or u8 bounded by a
certain open interval maximum, use prandom_u32_max()
I say "non-uniform", because it doesn't do any rejection sampling
or divisions. Hence, it stays within the prandom_*() namespace, not
the get_random_*() namespace.
I'm currently investigating a "uniform" function for 6.2. We'll see
what comes of that.
By applying these rules uniformly, we get several benefits:
- By using prandom_u32_max() with an upper-bound that the compiler
can prove at compile-time is ≤65536 or ≤256, internally
get_random_u16() or get_random_u8() is used, which wastes fewer
batched random bytes, and hence has higher throughput.
- By using prandom_u32_max() instead of %, when the upper-bound is
not a constant, division is still avoided, because
prandom_u32_max() uses a faster multiplication-based trick instead.
- By using get_random_u16() or get_random_u8() in cases where the
return value is intended to indeed be a u16 or a u8, we waste fewer
batched random bytes, and hence have higher throughput.
This series was originally done by hand while I was on an airplane
without Internet. Later, Kees and I worked on retroactively figuring
out what could be done with Coccinelle and what had to be done
manually, and then we split things up based on that.
So while this touches a lot of files, the actual amount of code that's
hand fiddled is comfortably small"

The prandom_u32() function has been a deprecated inline wrapper around
get_random_u32() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. The same also applies to get_random_int(), which is
just a wrapper around get_random_u32(). This was done as a basic find
and replace.

PSI accounts stalls for each cgroup separately and aggregates it
at each level of the hierarchy. This may cause non-negligible overhead
for some workloads when under deep level of the hierarchy.
commit 3958e2d0c34e ("cgroup: make per-cgroup pressure stall tracking configurable")
make PSI to skip per-cgroup stall accounting, only account system-wide
to avoid this each level overhead.
But for our use case, we also want leaf cgroup PSI stats accounted for
userspace adjustment on that cgroup, apart from only system-wide adjustment.
So this patch introduce a per-cgroup PSI accounting disable/re-enable
interface "cgroup.pressure", which is a read-write single value file that
allowed values are "0" and "1", the defaults is "1" so per-cgroup
PSI stats is enabled by default.
Implementation details:
It should be relatively straight-forward to disable and re-enable
state aggregation, time tracking, averaging on a per-cgroup level,
if we can live with losing history from while it was disabled.
I.e. the avgs will restart from 0, total= will have gaps.
But it's hard or complex to stop/restart groupc->tasks[] updates,
which is not implemented in this patch. So we always update
groupc->tasks[] and PSI_ONCPU bit in psi_group_change() even when
the cgroup PSI stats is disabled.

Now PSI already tracked workload pressure stall information for
CPU, memory and IO. Apart from these, IRQ/SOFTIRQ could have
obvious impact on some workload productivity, such as web service
workload.
When CONFIG_IRQ_TIME_ACCOUNTING, we can get IRQ/SOFTIRQ delta time
from update_rq_clock_task(), in which we can record that delta
to CPU curr task's cgroups as PSI_IRQ_FULL status.
Note we don't use PSI_IRQ_SOME since IRQ/SOFTIRQ always happen in
the current task on the CPU, make nothing productive could run
even if it were runnable, so we only use PSI_IRQ_FULL.

Cortex-A55 is affected by an erratum where in rare circumstances the
CPUs may not handle a race between a break-before-make sequence on one
CPU, and another CPU accessing the same page. This could allow a store
to a page that has been unmapped.
Work around this by adding the affected CPUs to the list that needs
TLB sequences to be done twice.

The device trees produced automatically for the virt and spike machines

Patches been sent that fix the QEMU issues [0], but a couple of them

compatibles for "riscv,{clint,plic}0" which are present in drivers and
the auto generated QEMU dtbs.
Thanks to Rob Herring for reporting these issues [1],
Conor.
To reproduce the errors:
./build/qemu-system-riscv64 -nographic -machine virt,dumpdtb=qemu.dtb
dt-validate -p /path/to/linux/kernel/Documentation/devicetree/bindings/processed-schema.json qemu.dtb
(The processed schema needs to be generated first)

The QEMU virt and spike machines currently export a riscv,isa string of
"rv64imafdcsuh",
While the RISC-V foundation has been ratifying a bunch of extenstions
etc, the kernel has remained relatively static with what hardware is
supported - but the same is not true of QEMU. Using the virt machine
and running dt-validate on the dumped dtb fails, partly due to the
unexpected isa string.
Rather than enumerate the many many possbilities, change the pattern
to a regex, with the following assumptions:
- ima are required
- the single letter order is fixed & we don't care about things that
can't even do "ima"
- the standard multi letter extensions are all in a "_z<foo>" format
where the first letter of <foo> is a valid single letter extension
- _s & _h are used for supervisor and hyper visor extensions
- convention says that after the first two chars, a standard multi
letter extension name could be an english word (ifencei anyone?) so
it's not worth restricting the charset
- as the above is just convention, don't apply any charset restrictions
to reduce future churn
- vendor ISA extensions begind with _x and have no charset restrictions
- we don't care about an e extension from an OS pov
- that attempting to validate the contents of the multiletter extensions
with dt-validate beyond the formatting is a futile, massively verbose
or unwieldy exercise at best
The following limitations also apply:
- multi letter extension ordering is not enforced. dt-schema does not
appear to allow for named match groups, so the resulting regex would
be even more of a headache
- ditto for the numbered extensions
Finally, add me as a maintainer of the binding so that when it breaks
in the future, I can be held responsible!

Microchip RISC-V devicetrees for v6.1
Fixups, reference design changes and new boards:
- The addition of QSPI support for mpfs had a corresponding change to
the devicetree node.
- The v2022.{09,10} reference designs brought with them several memory
map changes which are not backwards compatible. The old devicetrees
from the v2022.08 and earlier releases still work with current
kernels.
- Two new devicetrees for a first-party development kit and for the
Aries Embedded M100FPSEVP kit.
- Corresponding dt-bindings changes for the above.

The icicle kit reference design's v2022.09 release made some changes
to the memory map - including adding the ability to read the fabric
clock controllers via the system controller bus & making the PCI
controller work with upstream Linux.
While the PCI was not working in the v2022.03 design, so nothing is
broken there in terms of backwards compatibility, the fabric clocks
used in the v2022.03 design were chosen by the individual run of the
synthesis tool. In the v2022.09 reference design, the clocks are fixed
to use the "north west" fabric Clock Conditioning Circuitry.
In the v2022.10 release, the memory map on the DDR side is also
changing, so to avoid making a breaking change here twice, jump over the
v2022.09 release and straight to the v2022.10 one.
Make use of a new compatible to denote that v2022.{09,10} reference
design releases are not backwards compatible.

The RISC-V ISA manual used to mandate that misaligned accesses were
supported in user mode, but that requirement was removed in 2018 via
riscv-isa-manual commit 61cadb9 ("Provide new description of misaligned
load/store behavior compatible with privileged architecture."). Since
the Linux uABI was already frozen at that point it's just been demoted
to part of the uABI, but that was never written down.

The kernel size changes due to many factors, such as compiler
version, configuration, and the build environment. This makes
size comparison figures irrelevant to reader's setup.
Remove these figures and describe the effects of page owner
to the kernel size in general instead.

constructive suggestions.
