phy: Add RGMII support on lan966x

The serdes driver contains also a mux to decide which interface type to
use. Currently the driver supports GMII/SGMII/QSGMII and partially RGMII.
As it doesn't support all the other RGMII interfaces like
RGMII_TXID/RXID/ID and it could run only at 1G.
Therefore extend this for all the other speeds(10/100) and also allow
the other interfaces.

phy: rockchip-inno-usb2: Return zero after otg sync

The otg sync state patch reuses the ret variable, but fails to set it to
zero after use. This leads to a situation when the otg port is in
peripheral mode where the otg phy aborts halfway through setup.  It also
fails to account for a failure to register the extcon notifier. Fix this
by using our own variable and skipping otg sync in case of failure.

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.

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.
