Document that the only way to get the interrupt thread is to use
curthread->td_intr_frame, rather than the old-style of having a NULL
pointer for the interrupt thread. As of 38c35248fe, support for that
has been removed. I neglected to update that commit message with these
details.

While otherwise a handy potential approach, getting the trap frame via
the argument isn't documented and isn't supposed to be used. With all
uses removed, now remove support to end the mixed calling conventions.

GCC 13 complains that we might be writing too much to an on-stack buffer
when createing a filename.
In practice there is a check that filename isn't too long given the
time format and other static characters so GCC is incorrect, but GCC
isn't wrong that we're potentially trying to put a MAXPATHLEN length
string + some other characters into a MAXPATHLEN buffer (if you ignore
the check GCC can't realistically evaluate at compile time).
Switch to snprintf to populate filename to ensure that future logic
errors don't result in a stack overflow.
Shorten the questionably named yyyymmdd buffer enough to slience the
warning (checking the snprintf return value isn't sufficent) while
preserving maximum flexibility for admins who use the -F option.

It turns out this wasn't in 4.4BSD. I had a false positive for gdc.c
(which is in 4.4BSD, but part of gated, not this). gdc.c comes from the
ncurses tests, so it shouldn't have this copyright. This version is
mostly Amos Shapir and John Lupien's code. It comes from ncurses test
directory. ncurses has made dozens of improvements to this file since
we imported it in 1997 (which pre-dates their online history), so it's
not clear if their new copyright applies (which doesn't mention Amos
or John) or if some other copyright applies. In any case, it wasn't
4.4BSD, so revert this.
This reverts commit 6ed7d0e3ac.

Though the kernel build expects ${.OBJDIR} to be equal to ${.CURDIR}
that may not always be the case. Correctly generate fdt_static_dtb.h in

Summary:
In some cases the TPM utilities may read only a partial block, instead
of a full block. If a new command starts while in the middle of a read
it may cause the TPM to go catatonic and no longer respond to SPI.

Ensure the spintable release address is written back from the cache
to memory. The other CPUs reading this may not be reading it with the
cache enabled so ensure it is written to the point of coherency
before issuing the wakeup sev.
As cpu_dcache_wbinv_range includes the needed barrier remove it from
the inline asm before the sev instruction.
