Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.
As a minor optimization, this also lets us drop of_match_ptr(), as we
now know what it will resolve to, we might as well save cpp some work.

The current code will, if we do not specify unique labels
for the SRAM subnodes, fail to register several nodes named
the same.
Example:
sram@40020000 {
(...)
sram@0 {
(...)
};
sram@1000 {
(...)
};
};
Since the child->name in both cases will be "sram" the
gen_pool_create() will fail because the name is not unique.
Use dev_name() for the device as this will have bus ID
set to the fully translated address for the node, and that
will always be unique.

Function ll_rw_block was removed in commit 79f597842069 ("fs/buffer:
remove ll_rw_block() helper"). There is no unified function to sumbit
read or write buffer in block layer for now. Consider similar sematics,
we can choose submit_bh() to replace ll_rw_block() as predefined crash
point. In submit_bh(), it also takes read or write flag as the first
argument and invoke submit_bio() to submit I/O request to block layer.

Add a Device Feature List (DFL) feature id as a generic mechanism
to expose a vendor-specific FPGA IP to user space. The feature id
is intended for use with IPs that do not need any kernel services
beyond exposure to user space through the UIO DFL driver.
The feature id is used in, e.g., Intel Oak Springs Canyon IPUs
to expose various IPs to user space, e.g., Network Controller
Sideband Interface (NC-SI), BaseNIC, and VirtIO management.

The inode can be different in a container, for example, a docker and host
both open the same uacce parent device, which uses the same uacce struct
but different inode, so uacce->inode is not enough.
What's worse, when docker stops, the inode will be destroyed as well,
causing use-after-free in uacce_remove.

- binder fixes and reverts for reported problems and regressions in

There have not been a lot of fixes for for the soc tree in 6.4, but
these have been sitting here for too long.
For the devicetree side, there is one minor warning fix for vexpress,
the rest all all for the the NXP i.MX platforms: SoC specific bugfixes
for the iMX8 clocks and its USB-3.0 gadget device, as well as board
specific fixes for regulators and the phy on some of the i.MX boards.
The microchip risc-v and arm32 maintainers now also add a shared
maintainer file entry for the arm64 parts.
The remaining fixes are all for firmware drivers, addressing mistakes in
the optee, scmi and ff-a firmware driver implementation, mostly in the
error handling code, incorrect use of the alloc_workqueue() interface in
SCMI, and compatibility with corner cases of the firmware implementation.

When media is not ready do not assume that the capacity information from

zero out the capacity resources and exit early.
Given zero-init of those fields this patch is functionally equivalent to

I tried to streamline our user memory copy code fairly aggressively in
commit adfcf4231b8c ("x86: don't use REP_GOOD or ERMS for user memory
copies"), in order to then be able to clean up the code and inline the
modern FSRM case in commit 577e6a7fd50d ("x86: inline the 'rep movs' in
user copies for the FSRM case").
We had reports [1] of that causing regressions earlier with blogbench,
but that turned out to be a horrible benchmark for that case, and not a
sufficient reason for re-instating "rep movsb" on older machines.
However, now Eric Dumazet reported [2] a regression in performance that
seems to be a rather more real benchmark, where due to the removal of
"rep movs" a TCP stream over a 100Gbps network no longer reaches line
speed.
And it turns out that with the simplified the calling convention for the
non-FSRM case in commit 427fda2c8a49 ("x86: improve on the non-rep
'copy_user' function"), re-introducing the ERMS case is actually fairly
simple.
Of course, that "fairly simple" is glossing over several missteps due to
having to fight our assembler alternative code. This code really wanted
to rewrite a conditional branch to have two different targets, but that
made objtool sufficiently unhappy that this instead just ended up doing
a choice between "jump to the unrolled loop, or use 'rep movsb'
directly".
Let's see if somebody finds a case where the kernel memory copies also
care (see commit 68674f94ffc9: "x86: don't use REP_GOOD or ERMS for
small memory copies"). But Eric does argue that the user copies are
special because networking tries to copy up to 32KB at a time, if
order-3 pages allocations are possible.
In-kernel memory copies are typically small, unless they are the special
"copy pages at a time" kind that still use "rep movs".
