arm64: dts: ti: k3-j7200: Enable PCIe nodes at the board level

PCIe node defined in the top-level J7200 SoC dtsi file is incomplete
and will not be functional unless it is extended with a SerDes PHY.

As the PHY and mode is only known at the board integration level, this
node should only be enabled when provided with this information.

Disable the PCIe node in the dtsi files and only enable when it is
actually pinned out on a given board.

arm64: dts: ti: k3-am625-beagleplay: Use the builtin mdio bus

The beagleplay dts was using a bit-bang gpio mdio bus as a work-around
for errata i2329. However since commit d04807b80691 ("net: ethernet: ti:
davinci_mdio: Add workaround for errata i2329") the mdio driver itself
already takes care of this errata for effected silicon, which landed
well before the beagleplay dts. So i suspect the reason for the
workaround in upstream was simply due to copying the vendor dts.

Switch the dts to the ti,cpsw-mdio instead so it described the actual
hardware and is consistent with other AM625 based boards

bcachefs: Prep work for variable size btree node buffers

bcachefs btree nodes are big - typically 256k - and btree roots are
pinned in memory. As we're now up to 18 btrees, we now have significant
memory overhead in mostly empty btree roots.

And in the future we're going to start enforcing that certain btree node
boundaries exist, to solve lock contention issues - analagous to XFS's
AGIs.

Thus, we need to start allocating smaller btree node buffers when we
can. This patch changes code that refers to the filesystem constant
c->opts.btree_node_size to refer to the btree node buffer size -
btree_buf_bytes() - where appropriate.

======================================================

In __bch2_ioctl_subvolume_create(), we grab s_umount unconditionally
and unlock it at the end of the function. There is a comment
"why do we need this lock?" about the lock coming from
commit 42d237320e98 ("bcachefs: Snapshot creation, deletion")
The reason is that __bch2_ioctl_subvolume_create() calls
sync_inodes_sb() which enforce locked s_umount to writeback all dirty
nodes before doing snapshot works.

Fix it by read locking s_umount for snapshotting only and unlocking
s_umount after sync_inodes_sb().

media: solo6x10: replace max(a, min(b, c)) by clamp(b, a, c)

This patch replaces max(a, min(b, c)) by clamp(b, a, c) in the solo6x10
driver.  This improves the readability and more importantly, for the
solo6x10-p2m.c file, this reduces on my system (x86-64, gcc 13):

 - the preprocessed size from 121 MiB to 4.5 MiB;

 - the build CPU time from 46.8 s to 1.6 s;

 - the build memory from 2786 MiB to 98MiB.

In fine, this allows this relatively simple C file to be built on a
32-bit system.

coccinelle: device_attr_show: simplify patch case

Replacing the final expression argument by ... allows the format
string to have multiple arguments.

It also has the advantage of allowing the change to be recognized as
a change in a single statement, thus avoiding adding unneeded braces.

execve: open the executable file before doing anything else

No point in allocating a new mm, counting arguments and environment
variables etc if we're just going to return ENOENT.

This patch does expose the fact that 'do_filp_open()' that execve() uses
is still unnecessarily expensive in the failure case, because it
allocates the 'struct file *' early, even if the path lookup (which is
heavily optimized) fails.

So that remains an unnecessary cost in the "no such executable" case,
but it's a separate issue.  Regardless, I do not want to do _both_ a
filename_lookup() and a later do_filp_open() like the origin patch by
Josh Triplett did in [1].
