Input: applespi - replace zero-length array with DECLARE_FLEX_ARRAY() helper
Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members, instead. So, replace zero-length arrays
declarations in anonymous union with the new DECLARE_FLEX_ARRAY()
helper macro.
This helper allows for flexible-array members in unions.
rmi_f34v7_enter_flash_prog() already enables IRQs and checks the flash
status - there's no need for rmi_f34v7_start_reflash() to do the same just
before calling rmi_f34v7_enter_flash_prog().
All register offsets are fixed, and a number of places even read or
write multiple registers as a block, so there is no way to support
reordering them without move involved changes. Remove the unneeded level
of indirection in the register access.
Input: synaptics-rmi4 - make rmi_f34v7_erase_all() use the "erase all" command
A full erase is required to recover from error conditions like "Bad
Partition Table". Various individual partition erase commands can be
(and need to be) omitted, as they will fail until a new partition table
has been written.
Input: synaptics-rmi4 - reset after writing partition table
When recovering from a bad partition table (for example after an
interrupted update), a reset is necessary for the new partition table to
become effective. Without this reset, writing the core code partition
will fail with status 0x03 (Invalid Command).
Preparation for use of the "erase application" command, which is required
to recover from a bad partition table error condition. Rather than adding
complex fallback error paths for such errors, it seems more robust to do
the full erase unconditionally.
Input: synaptics-rmi4 - fix command completion check for bootloader v7/v8
The command register is reset to 0 when a command has completed. Check
for this condition instead of the error status, which will not accurately
reflect completion. In particular, the incorrect condition caused every
command error to be reported as a timeout.
Add a function that waits for the last command to complete and checks
the status, and use it where appropriate. This prepares for the subsequent
fix of the completion condition in rmi_f34_attention(), which would
previously lead to a timeout instead of a more detailed error message
whenever a command was unsuccessful with v7/v8 bootloaders.

This patch also introduces correct handling for the Elite 1 controller
and properly suppresses paddle inputs when using a custom profile slot.

We must first manually enable this extra packet in order to correctly

Input: adp5588-keys - support gpi key events as 'gpio keys'
This change replaces the support for GPIs as key event generators.
Instead of reporting the events directly, we add a gpio based irqchip
so that these events can be consumed by keys defined in the gpio-keys
driver (as it's goal is indeed for keys on GPIOs capable of generating
interrupts). With this, the gpio-adp5588 driver can also be dropped.
The basic idea is that all the pins that are not being used as part of
the keymap matrix can be possibly requested as GPIOs by gpio-keys
(it's also fine to use these pins as plain interrupts though that's not
really the point).
Since the gpiochip now also has irqchip capabilities, we should only
remove it after we free the device interrupt (otherwise we could, in
theory, be handling GPIs interrupts while the gpiochip is concurrently
removed). Thus the call 'adp5588_gpio_add()' is moved and since the
setup phase also needs to come before making the gpios visible, we also
need to move 'adp5588_setup()'.
While at it, always select GPIOLIB so that we don't need to use #ifdef
guards.

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.
