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.

When this driver was written it made sense to make this default to off,
but these days almost all BIOSses will do the right thing. Furthermore
non-mmio communication only works on Intel architectures.
So lets default to allowing mmio, but not change the semantics of the
AHC_ALLOW_MEMIO flag to not break existing installs. Also document the
already existing hint.ahc.<unit>.allow_memio.

For a very long time, the NFS client has done readahead for
directory blocks. Unlike data blocks, the readahead cannot
begin until the Readdir RPC reply has been received, since
the directory offset cookie in that Readdir RPC reply is needed.
As such, the readahead is serialized and does not seem to
provide any real benefit.
Recent testing/benchmarking shows that removing this
readahead code for Readdir does not have a negative impact
on performance.
Therefore, this patch deletes the readahead code for Readdir,
which simplifies the code and may make future changes simpler.

Introduce hw.bus.devctl_nomatch_enabled and use it to suppress NOMATCH
until devmatch runs
There's a lot of NOMATCH events generated at boot. We also run devmatch
once during early boot to load unmatched devices. To avoid redundant
work, don't start generating NOMATCH events until after devmatch runs.
Set hw.bus.devctl_nomatch_enabled=1 just before we run devmatch. The
kernel will suppress NOMATCH events until this is set to true.
This saves about 170ms from the boot on aarch64 running atop Apple
M-series processors and the VMWare Fusion hypervisor.
