It was a driver for a USB FM tuner that was available in the market in 2002. I
wrote the driver in 2003. I've not used it since 2005 or so, so it's time to
retire this driver. No userland code ever interfaced to the special device it
created. There's no user base: the last bug I received on this driver was in
2004.
Relnotes: Yes
This was discussed in arch@ a while ago. Most of the 16-bit drivers that it
relied on have been removed. There's only a few other drivers remaining that
support it, and those are very rare the days (even the once ubiquitious wi(1)
is now quite rare).
Indvidual drivers will be handled separately before pccard itself is removed.
This is only needed when linking and fixes various "unused command
line argument" warnings during the lib32 build.

Add prng(9) as a replacement for random(9) in the kernel.
There are two major differences from random(9) and random(3):
- General prng(9) APIs (prng32(9), etc) do not guarantee an
implementation or particular sequence; they should not be used for
repeatable simulations.
- However, specific named API families are also exposed (for now: PCG),
and those are expected to be repeatable (when so-guaranteed by the named
algorithm).
Some minor differences from random(3) and earlier random(9):
- PRNG state for the general prng(9) APIs is per-CPU; this eliminates
contention on PRNG state in SMP workloads. Each PCPU generator in an
SMP system produces a unique sequence.
- Better statistical properties than the Park-Miller ("minstd") PRNG
(longer period, uniform distribution in all bits, passes
BigCrush/PractRand analysis).
- Faster than Park-Miller ("minstd") PRNG -- no division is required to
step PCG-family PRNGs.
For now, random(9) becomes a thin shim around prng32(). Eventually I
would like to mechanically switch consumers over to the explicit API.

These tools require a bootstrap llvm-tblgen/clang-tblgen and that cannot
be built with the current make infrastructure: the config header is not
correct for Linux/macOS and we don't include the CMakeLists.txt in contrib
so we can't generate one that would be correct.

Since the make variable STRIP is already used for other purposes, this
uses STRIPBIN (which is also used for the same purpose by install(1).
This allows using LLVM objcopy to strip binaries instead of the in-tree
elftoolchain objcopy. We make use of this in CheriBSD since passing
binaries generated by our toolchain to elftoolchain strip sometimes results
in assertion failures.
This allows working around https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=248516
by specifying STRIPBIN=/path/to/llvm-strip

These functions were introduced before UMA started ensuring that freed
memory gets placed in domain-local caches. They no longer serve any
purpose since UMA now provides their functionality by default. Remove
them to simplyify the kernel memory allocator interfaces a bit.

- In the initial description of si_addr, do not claim that it is
always the faulting instruction.
- For si_addr, document that it is generally set to the PC for
synchronous signals, but that it can be set to the the address of
the faulting memory reference for some signals including SIGSEGV and
SIGBUS. In particular, while SIGSEGV generally sets si_addr to the
faulting memory reference, SIGBUS can vary. On some platforms, some
SIGBUS signals set si_addr to the PC and other SIGBUS signals set
si_addr to the faulting address depending on the specific hardware
exception.
- For si_trapno, synchronous signals should set this to some value.

For purposes of handling hardware error reported via NMIs I need a way to
escape NMI context, being too restrictive to do something significant.
To do it this change introduces new swi_sched() flag SWI_FROMNMI, making
it careful about used KPIs. On platforms allowing IPI sending from NMI
context (x86 for now) it immediately wakes clk_intr_event via new IPI_SWI,
otherwise it works just like SWI_DELAY. To handle the delayed SWIs this
patch calls clk_intr_event on every hardclock() tick.
