dt-bindings: rng: omap_rng: Drop requirement for clocks

For K3 devices the clock fed into the RNG module is shared with the rest
of the Crypto module, it is not dedicated to the RNG module and cannot be
controlled by the RNG driver. The driver does not require this clock to
always be defined and the DT binding should not force it either.

Remove this so we can start dropping out the clock properties as needed.

of: irq: Report individual failures in of_irq_init()

New pr_err(), a copy of preceeding pr_debug(), faciliates debugging.

This change was inspired by a long lasting debugging of the
octeon_irq_init_ciu() which fails completely silently and leaves the
interrupt controller half-way configured which in turn had very non-obvious
effects.

dt-bindings: misc: fastrpc convert bindings to yaml

Convert Qualcomm FastRPC bindings to yaml format, so that we could validate
dt-entries correctly and any future additions can go into yaml format.

Use compute-cb@ subnodes instead of just cb@. Add qcom,glink-channels and
qcom,smd-channels missing properties to make sure dtbs_check doesn't fail
right off the bat. Correct the name of the parent node in the example from
smd-edge to glink-edge.

Since now the qcom,fastrpc bindings document is yaml, update the
reference to it in qcom,glink-edge and also use $ref.

Also update the MAINTAINERS file to point to the yaml version.

Merge tag 'powerpc-6.0-2' of git://git./linux/kernel/git/powerpc/linux

Pull powerpc fixes from Michael Ellerman:

 - Ensure we never emit lwarx with EH=1 on 32-bit, because some 32-bit
   CPUs trap on it rather than ignoring it as they should.

 - Fix ftrace when building with clang, which was broken by some
   refactoring.

 - A couple of other minor fixes.

Thanks to Christophe Leroy, Naveen N.  Rao, Nick Desaulniers, Ondrej
Mosnacek, Pali Rohár, Russell Currey, and Segher Boessenkool.

afs: Enable multipage folio support

Enable multipage folio support for the afs filesystem.

Support has already been implemented in netfslib, fscache and cachefiles
and in most of afs, but I've waited for Matthew Wilcox's latest folio
changes.

Note that it does require a change to afs_write_begin() to return the
correct subpage.  This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.

perf test: Refactor shell tests allowing subdirs

This is a prelude to adding more tests to shell tests and in order to
support putting those tests into subdirectories, I need to change the
test code that scans/finds and runs them.

To support subdirs I have to recurse so it's time to refactor the code
to allow this and centralize the shell script finding into one location
and only one single scan that builds a list of all the found tests in
memory instead of it being duplicated in 3 places.

This code also optimizes things like knowing the max width of desciption
strings (as we can do that while we scan instead of a whole new pass of
opening files).

It also more cleanly filters scripts to see only *.sh files thus
skipping random other files in directories like *~ backup files, other
random junk/data files that may appear and the scripts must be
executable to make the cut (this ensures the script lib dir is not seen
as scripts to run).

This avoids perf test running previous older versions of test scripts
that are editor backup files as well as skipping perf.data files that
may appear and so on.

perf jevents: Fold strings optimization

If a shorter string ends a longer string then the shorter string may
reuse the longer string at an offset. For example, on x86 the event
arith.cycles_div_busy and cycles_div_busy can be folded, even though
they have difference names the strings are identical after 6
characters. cycles_div_busy can reuse the arith.cycles_div_busy string
at an offset of 6.

In pmu-events.c this looks like the following where the 'also:' lists
folded strings:

/* offset=177541 */ "arith.cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000" /* also: cycles_div_busy\000\000pipeline\000Cycles the divider is busy\000\000\000event=0x14,period=2000000,umask=0x1\000\000\000\000\000\000\000\000\000 */

As jevents.py combines multiple strings for an event into a larger
string, the amount of folding is minimal as all parts of the event must
align. Other organizations can benefit more from folding, but lose space
by say recording more offsets.

perf jevents: Compress the pmu_events_table

The pmu_events array requires 15 pointers per entry which in position
independent code need relocating. Change the array to be an array of
offsets within a big C string. Only the offset of the first variable is
required, subsequent variables are stored in order after the \0
terminator (requiring a byte per variable rather than 4 bytes per
offset).

The file size savings are:

no jevents - the same 19,788,464bytes
x86 jevents - ~16.7% file size saving 23,744,288bytes vs 28,502,632bytes
all jevents - ~19.5% file size saving 24,469,056bytes vs 30,379,920bytes
default build options plus NO_LIBBFD=1.

For example, the x86 build savings come from .rela.dyn and
.data.rel.ro becoming smaller by 3,157,032bytes and 3,042,016bytes
respectively. .rodata increases by 1,432,448bytes, giving an overall
4,766,600bytes saving.

To make metric strings more shareable, the topic is changed from say
'skx metrics' to just 'metrics'.

To try to help with the memory layout the pmu_events are ordered as used
by perf qsort comparator functions.

perf pmu-events: Don't assume pmu_event is an array

The current code assumes that a struct pmu_event can be iterated over
forward until a NULL pmu_event is encountered.

This makes it difficult to refactor pmu_event.

Add a loop function taking a callback function that's passed the struct
pmu_event.

This way the pmu_event is only needed for one element and not an entire
array.

Switch existing code iterating over the pmu_event arrays to use the new
loop function pmu_events_table_for_each_event.

which is putting events with descriptions and topics before those

fs: don't randomize struct kiocb fields

This is a size sensitive structure and randomizing can introduce extra
padding that breaks io_uring's fixed size expectations. There are few
fields here as it is, half of which need a fixed order to optimally

dt-bindings: gpio: sifive: add gpio-line-names

Fix device tree schema validation messages like 'gpio-line-names'
does not match any of the regexes: 'pinctrl-[0-9]+' From schema: ...
sifive,gpio.yaml'.

The bindings were missing the gpio-line-names element, which was
causing the dt-schema checker to trip-up.

wireguard: selftests: set CONFIG_NONPORTABLE on riscv32

When the CONFIG_PORTABLE/CONFIG_NONPORTABLE switches were added, various
configs were updated, but the wireguard config was forgotten about. This
leads to unbootable test kernels, causing CI fails. Add
CONFIG_NONPORTABLE=y to the wireguard test suite configuration for
riscv32.

RISC-V: KVM: Support sstc extension

Sstc extension allows the guest to program the vstimecmp CSR directly
instead of making an SBI call to the hypervisor to program the next
event. The timer interrupt is also directly injected to the guest by
the hardware in this case. To maintain backward compatibility, the
hypervisors also update the vstimecmp in an SBI set_time call if
the hardware supports it. Thus, the older kernels in guest also
take advantage of the sstc extension.
