In a multiplatform kernel that includes both pxa and mmp, we get a link
failure from the clash of two pxa_register_device functions.
Rename the one in mach-mmp to mmp_register_device, along with with the
rename of pxa_device_desc.

There are two tavorevb boards in the kernel, one using a PXA930 chip in
mach-pxa, and one using the later PXA910 chip in mach-mmp. They use the
same board number, which is generally a bad idea, and in a multiplatform
kernel, we can end up with funny link errors like this one resulting
from two boards gettting controlled by the same Kconfig symbol:
arch/arm/mach-mmp/tavorevb.o: In function `tavorevb_init':
tavorevb.c:(.init.text+0x4c): undefined reference to `pxa910_device_uart1'
tavorevb.c:(.init.text+0x50): undefined reference to `pxa910_device_gpio'
tavorevb.o:(.arch.info.init+0x54): undefined reference to `pxa910_init_irq'
tavorevb.o:(.arch.info.init+0x58): undefined reference to `pxa910_timer_init'
The mach-pxa TavorEVB seems much more complete than the mach-mmp one
that supports only uart, gpio and ethernet. Further, I could find no
information about the board on the internet aside from references to
the Linux kernel, so I assume this was never available outside of Marvell
and can be removed entirely.
There is a third board named TavorEVB in the Kconfig description,
but this refers to the "TTC_DKB" machine. The two are clearly
related, so I change the Kconfig description to just list both
names.

The sa1111.h header defines some constants using the bitfield

The clock register definitions are now used (almost) exclusively in the
clk driver, and that relies on no other mach/*.h header files any more.
Remove the dependency on mach/pxa*-regs.h by addressing the registers
as offsets from a void __iomem * pointer, which is either passed from
a board file, or (for the moment) ioremapped at boot time from a hardcoded
address in case of DT (this should be moved into the DT of course).

To avoid dereferencing hardwired constant pointers from a global header
file, change the driver to use devm_platform_ioremap_resource for getting
an __iomem pointer, and then using readl/writel on that.
Each pointer dereference gets changed by a search&replace, which leads
to a few overlong lines, but seems less risky than trying to clean up
the code at the same time.

The Tosa device (Sharp SL-6000) has a mishmash driver set-up
for the Toshiba TC6393xb MFD that includes a battery charger
and touchscreen and has some kind of relationship to the SoC
sound driver for the AC97 codec. Other devices define a chip
like this but seem only half-implemented, not really handling
battery charging etc.
This patch switches the Toshiba MFD device to provide GPIO
descriptors to the battery charger and SoC codec. As a result
some descriptors need to be moved out of the Tosa boardfile
and new one added: all SoC GPIO resources to these drivers
now comes from the main boardfile, while the MFD provide
GPIOs for its portions.
As a result we can request one GPIO from our own GPIO chip
and drop two hairy callbacks into the board file.
This platform badly needs to have its drivers split up and
converted to device tree probing to handle this quite complex
relationship in an orderly manner. I just do my best in solving
the GPIO descriptor part of the puzzle. Please don't ask me
to fix everything that is wrong with these driver to todays
standards, I am just trying to fix one aspect. I do try to
use modern devres resource management and handle deferred
probe using new functions where appropriate.

Add fn and fn_arg members into struct kernel_clone_args and test for
them in copy_thread (instead of testing for PF_KTHREAD | PF_IO_WORKER).
This allows any task that wants to be a user space task that only runs
in kernel mode to use this functionality.
The code on x86 is an exception and still retains a PF_KTHREAD test
because x86 unlikely everything else handles kthreads slightly
differently than user space tasks that start with a function.
The functions that created tasks that start with a function
have been updated to set ".fn" and ".fn_arg" instead of
".stack" and ".stack_size". These functions are fork_idle(),
create_io_thread(), kernel_thread(), and user_mode_thread().

UART 0 to 2 do not have DMA support, while UART 3 to 7 do.
Fill the "dmas" and "dma-names" properties for each of these nodes.
Please mind that these nodes go through the dmamux node which will
redirect the requests to the right DMA controller. The first 4 cells of
the "dmas" properties will be transferred as-is to the DMA
controllers. The last 2 cells are consumed by the dmamux. Which means
cell 0 and 4 are almost redundant, one giving the controller request ID
and the other the dmamux channel which is a 1:1 translation of the
request IDs, shifted by 16 when pointing to the second DMA controller.

Even smaller embedded systems are using systemd these days, as
are test automation systems like KernelCI, so it is useful to be
able to use systemd on these boards by default. Enable options
that are missing in the at91_dt_defconfig, cgroups which is
critical and autofs4 which is less critical but causes warnings
on boot when not available.

Address read only block filesystems like SquashFS, and use MTD_UBI_BLOCK

Using mtdblock on raw flashes is generally a bad idea as it lacks
wear-leveling, bad block handling or power-cut management.
What happens when you use mtdblock and you change any sector of your
mtdblockX device, is that it reads the whole corresponding eraseblock into
the memory, erases the eraseblock, changes the sector in RAM, and writes
the whole eraseblock back. If you have a power failure when the eraseblock
is being erased, you lose all the block device sectors in it. The flash
will likely decay soon because the eraseblocks will wear out.
Remove this archaic tool as its use case should rather be only for debug
purposes. This means that write-capable block file systems like ext2,
ext3, FAT, etc. will no longer be addressed with at91 defconfigs. For
read only block filesystems like SquashFS, use MTD_UBI_BLOCK instead and
benefit of UBI's bit-flip handling and wear-levelling.

Attempting to boot my Udoo Dual and Quad with mainline hangs during boot
after printing:
[ 3.270471] imx_usb 2184000.usb: No over current polarity defined
[ 3.922502] mxs_phy 20c9000.usbphy: Data pin can't make good contact.
[ 3.940097] imx_usb 2184200.usb: No over current polarity defined
where imx_usb 2184200.usb is usbh1 in the DT. Adding debug prints to the
code seems to show that we lock up at the first read in usbmisc_imx6q_init()
which in combination with the above logging about the USB controllers
suggests that we lock up on the first read in usbmisc_imx6q_init(). Looking
at some of the other i.MX6 boards and the warning messages that are being
printed suggests that there is bitrot in the DTS for the device so disable
it for now, with it disabled the board boots successfully. Clearly this is
not a real fix, but it does allow some use of the board with mainline.
Similar behaviour is seen all the way back as far as v4.19, I tried going
back to when the board was added but had toolchain issues. Vendor provided
binaries seem fine on the boards so it seems likely that the hardware is
fine and the issue is with some combination of the DT and kernel. This
should obviously be resolved properly but for now this at least allows
the kernel to boot with reduced functionality on these systems.

Configure the touchscreen found on the new display module of the FP2.
To add some detail, FP2 has two different screen/touchscreen variants
("display module"), the old module has Synaptics touchscreen, the new
one this Ilitek touchscreen.
We're only supporting the new display module for now.

After converting to multiplatform the old IXP4xx defconfig
doesn't even activate the ethernet driver anymore, we need
to refresh this thoroughly.
- Drop options that ARCH_MULTI_V5 selects for us.
- Some options moved around because of multiplatform and
because generic Kconfig movements.
- Drop all MACH_* that do not exist anymore.
- Compress the kernel and initramfs with XZ as the memory
is often limited for these machines.
- Make sure IXP4XX_QMGR and IXP4XX_NPE is selected.
- Make sure the MTD_PHYSMAP_IXP4XX is selected and not
the old MTD_IXP4XX (will be deleted).
- Activate CRYPTO_DEV_IXP4XX
- Add some very basic default drivers such as AT24 EEPROMs
used in many routers.
- Add some kernel configs needed to bring up OpenWrt
which is the only userspace for these devices:
CGROUPS, DEVTMPFS, INOTIFY_USER, SIGNALFD, TIMERFD,
EPOLL, OVERLAY_FS and SQUASHFS.

The clksel related registers on omap3 cause unique_unit_address and
node_name_chars_strict warnings with the W=1 or W=2 make flags enabled.
With the clock drivers updated, we can now avoid most of these warnings
by grouping the TI component clocks using the TI clksel binding, and
with the use of clock-output-names property to avoid non-standard node

Patch series "Convert vmcore to use an iov_iter", v5.
For some reason several people have been sending bad patches to fix
compiler warnings in vmcore recently. Here's how it should be done.
Compile-tested only on x86. As noted in the first patch, s390 should take
this conversion a bit further, but I'm not inclined to do that work
myself.
This patch (of 3):
Instead of passing in a 'buf' and 'userbuf' argument, pass in an iov_iter.
s390 needs more work to pass the iov_iter down further, or refactor, but
I'd be more comfortable if someone who can test on s390 did that work.
It's more convenient to convert the whole of read_from_oldmem() to take an
iov_iter at the same time, so rename it to read_from_oldmem_iter() and add
a temporary read_from_oldmem() wrapper that creates an iov_iter.

Moving sram code from plat-omap got the attention of the kernel test robot.
I found a few more places with related warnings because the sram
references are a mix of kernel pointers and __iomem pointers:

mach-omap1/board-ams-delta.c:667:9: warning: incorrect type in argument 1 (different base types)

There is no good solution here, as sram is a bit special in this
regard. Change the annotations to at least shut up the warnings.

In a recent discussion[1] it was reported that the binfmt_flat library
support was only ever used on m68k and even on m68k has not been used
in a very long time.
The structure of binfmt_flat is different from all of the other binfmt
implementations because of this shared library support and it made
life and code review more effort when I refactored the code in fs/exec.c.
Since in practice the code is dead remove the binfmt_flat shared library
support and make maintenance of the code easier.

With SIGTRAP on perf events, we have encountered termination of
processes due to user space attempting to block delivery of SIGTRAP.
Consider this case:
<set up SIGTRAP on a perf event>
...
sigset_t s;
sigemptyset(&s);
sigaddset(&s, SIGTRAP | <and others>);
sigprocmask(SIG_BLOCK, &s, ...);
...
<perf event triggers>
When the perf event triggers, while SIGTRAP is blocked, force_sig_perf()
will force the signal, but revert back to the default handler, thus
terminating the task.
This makes sense for error conditions, but not so much for explicitly
requested monitoring. However, the expectation is still that signals
generated by perf events are synchronous, which will no longer be the
case if the signal is blocked and delivered later.
To give user space the ability to clearly distinguish synchronous from
asynchronous signals, introduce siginfo_t::si_perf_flags and
TRAP_PERF_FLAG_ASYNC (opted for flags in case more binary information is
required in future).
The resolution to the problem is then to (a) no longer force the signal
(avoiding the terminations), but (b) tell user space via si_perf_flags
if the signal was synchronous or not, so that such signals can be
handled differently (e.g. let user space decide to ignore or consider
the data imprecise).
The alternative of making the kernel ignore SIGTRAP on perf events if
the signal is blocked may work for some usecases, but likely causes
issues in others that then have to revert back to interception of
sigprocmask() (which we want to avoid). [ A concrete example: when using
breakpoint perf events to track data-flow, in a region of code where
signals are blocked, data-flow can no longer be tracked accurately.
When a relevant asynchronous signal is received after unblocking the
signal, the data-flow tracking logic needs to know its state is
imprecise. ]

This is the full series for converting OMAP1 to multiplatform, rebased
from my 2019 attempt to do the same thing. The soc tree contains simpler
patches to do the same for iop32x, ixp4xx, ep93xx and s3c24xx, which
means we are getting closer to completing this for all ARMv5 platforms
(I have patches for PXA, which is the last one remaining).
Janusz already tested the branch separately and did the missing work
for the common-clk conversion after my previous approach was broken.
