acpi_spmc(4): Small probe improvements/fixes
Remove the test on presence of an ACPI handle, this is implied by
ACPI_ID_PROBE() succeeding.
Set 'sc->dev' early, so that acpi_spmc_check_dsm_set() using
device_printf() will print the driver name.
Add a missing newline after printing that more DSM functions are
implemented then expected.

[LFI][Doc] Update documentation for planned features (#192128)
This PR updates the LFI documentation to be a little less
AArch64-specific in anticipation of x86-64 support. I've also updated
the planned names for the `no-lfi-stores`/`no-lfi-loads` features, and
updated the planned rewrite sequence for `x30` modifications to make it
more PAC-compatible for when we include support for that.
[RISCV] Support emitting plui.h for i32 constants on RV64. (#192534)
If the constant was originally i32, it will be sign or zero
extended to i64 during type legalization. If we can prove the
upper bits aren't used we can duplicate the lower bits to allow
RISCVMatInt to select plui.h.
[lit] Fix tests when run via symlinks (#192530)
If the path to Inputs/filter-failed was a symlink, it would copy the
symlinks, and then edit the same files, leading to flaky failures if the
tests ran in parallel.
[ThinLTO] Drop !inline_history metadata when importing functions (#192564)
In #190876 we now have functions in ValueAsMetadata (!inline_history
metadata). This has caused undefined symbol linker errors in some
ThinLTO builds. The following is what's going on:
@f in module A is getting imported from module A to module B, and it has
a call with !inline_history pointing to @g in module A, so a declaration
for @g is also imported into module B. But @g gets internalized in
module A, causing the undefined symbol error at link time due to
memprof's ICP in module B creating a call to @g since we can ICP a call
to any declaration.
To avoid pulling in a function declaration that may be wrong, simply
drop !inline_history metadata when importing functions. They aren't
necessary for correctness, they only prevent inlining explosion in some
recursive edge cases. Worst case is we do another round of inlining
through mutually recursive functions and then stop again due to newly
added !inline_history metadata, which should be fine; the inlining
explosion typically happens because we keep inlining through mutually
recursive functions.
Attempt to load the right device tree from the riscv64-specmit-dtb
firmware package on SpacemiT K1 boards. The only viable way to do this
seems to be basing this on the "model" property of the root node of
the device tree provided by the device. This is still a bit of a guess
since the Milk-V Jupiter advertises itself as "spacemit k1-x evb board"
and the Banana Pi BPI-F3 seems to say it is a "spacemit k1-x deb1 board".

uart/pci: recover ADL AMT device after FIFO size probing
When the Alder Lake Serial-over-LAN device is put into loopback mode and
repeated writes are performed to the data register it results in the device
ending up in a non-functional state afterwards.
Recovering the device to a working state requires re-writing the LCR
register with it's current value (no effective change). This should be
harmless on all other devices.

uart/pci: use different probe return values
For PCI devices listed in pci_ns8250_ids return BUS_PROBE_SPECIFIC, while
for generic UART devices not explicitly listed in pci_ns8250_ids return
BUS_PROBE_GENERIC. This allows more specific drivers to take over those
devices, and the generic UART PCI driver will only be used as a fallback.
This fixes an issue where the UART PCI driver would attach to multiport PCI
UART devices, that instead need to use the puc(4) driver to multiplex the
device.

If you use the floppy, fw_update for some drivers will not work, you will
have to figure out the names of the missing firmwares and request them
manually.
The pci strings in the kernel have become too large, and I'm being told I
may not shorten them.

[lldb] Assert lack of trailing period or newlines in diagnostics (#191447)
This PR adds an assert to `CommandReturnObject::{AppendNote,
AppendWarning}` to ensure the diagnostics don't end with a newline,
which is added by the function, or a period, which goes against the
coding standards.
I added a little helper that asserts in assert-enabled builds and trim
the diagnostic otherwise. I know that goes against the notion that
"asserts are preconditions" and therefore you shouldn't handle the case
where they don't hold (something I generally advocate for) but I think
we should prioritize a consistent user experience over purity.
We should do the same thing for `AppendError`, but currently there are
still too many violations that need to be cleaned up and if the compiler
emits non-compliant diagnostics, we may not be able to do this at all.
