Summary:
Add support for building ossl(4) on powerpc64* by implementing ossl_cpuid and
other support functions for powerpc. The required assembly files for ppc were
already present in-tree.

Test Plan: The changes were tested using the in-tree tools/tools/crypto/cryptocheck.c tool on both powerpc64 and powerpc64le on a POWER9 system.

sdt: Implement SDT probes using hot-patching

The idea here is to avoid a memory access and conditional branch per
probe site. Instead, the probe is represented by an "unreachable"
unconditional function call. asm goto is used to store the address of
the probe site (represented by a no-op sled) and the address of the
function call into a tracepoint record. Each SDT probe carries a list
of tracepoints.

When the probe is enabled, the no-op sled corresponding to each
tracepoint is overwritten with a jmp to the corresponding label. The
implementation uses smp_rendezvous() to park all other CPUs while the
instruction is being overwritten, as this can't be done atomically in
general. The compiler moves argument marshalling code and the
sdt_probe() function call out-of-line, i.e., to the end of the function.

Per gallatin@ in D43504, this approach has less overhead when probes are
disabled. To make the implementation a bit simpler, I removed support
for probes with 7 arguments; nothing makes use of this except a
regression test case. It could be re-added later if need be.

The approach taken in this patch enables some more improvements:
1. We can now automatically fill out the "function" field of SDT probe
names. The SDT macros let the programmer specify the function and
module names, but this is really a bug and shouldn't have been
allowed. The intent was to be able to have the same probe in
multiple functions and to let the user restrict which probes actually
get enabled by specifying a function name or glob.
2. We can avoid branching on SDT_PROBES_ENABLED() by adding the ability
to include blocks of code in the out-of-line path. For example:

if (SDT_PROBES_ENABLED()) {
int reason = CLD_EXITED;

if (WCOREDUMP(signo))
reason = CLD_DUMPED;
else if (WIFSIGNALED(signo))
reason = CLD_KILLED;
SDT_PROBE1(proc, , , exit, reason);
}

could be written

SDT_PROBE1_EXT(proc, , , exit, reason,
int reason;

reason = CLD_EXITED;
if (WCOREDUMP(signo))
reason = CLD_DUMPED;
else if (WIFSIGNALED(signo))
reason = CLD_KILLED;
);

In the future I would like to use this mechanism more generally, e.g.,
to remove branches and marshalling code used by hwpmc, and generally to
make it easier to add new tracepoint consumers without having to add
more conditional branches to hot code paths.

Consistently provide ffs/fls using builtins

Use of compiler builtin ffs/ctz functions will result in optimized
instruction sequences when possible, and fall back to calling a function
provided by the compiler run-time library. We have slowly shifted our
platforms to take advantage of these builtins in 60645781d613 (arm64),
1c76d3a9fbef (arm), 9e319462a03a (powerpc, partial).

Some platforms still rely on the libkern implementations of these
functions provided by libkern, namely riscv, powerpc (ffs*, flsll), and
i386 (ffsll and flsll). These routines are slow, as they perform a
linear search for the bit in question. Even on platforms lacking
dedicated bit-search instructions, such as riscv, the compiler library
will provide better-optimized routines, e.g. by using binary search.

Consolidate all definitions of these functions (whether currently using
builtins or not) to libkern.h. This should result in equivalent or
better performing routines in all cases.

One wart in all of this is the existing HAVE_INLINE_F*** macros, which
we use in a few places to conditionally avoid the slow libkern routines.
These aren't easily removed in one commit. For now, provide these
defines unconditionally, but marked for removal after subsequent
cleanup.

Removal of the now unused libkern routines will follow in the next
commit.

This interface already existed in the standalone out-of-tree
1.34.2 driver; this commit adds and enables it in the in-kernel
driver.

Note:

Adds hack to module Makefile to compile interface/.m files

These are required for the RDMA client interface, but they don't
build as-is like the normal .c files. The source directory doesn't
seem to be included by default, so add lines that specifically
add them as libraries so that ice_rdma.h can be found and the
interface files will compile.

Summary:
Disable timebase on (some) AIM platforms (tested on PowerMac G4) prior

Some platforms use a GPIO to enable and disable timebase, while others

This mirrors 0d69f00b on mpc85xx.

Todo:
* Implement various G5 timebase controls.
* Print out platform code on unknown G5s so we can collect it.
* Change API to be give/take pairs like Linux does so it's possible to
do a software sync protocol.

in_cksum() and related routines are implemented separately for each
platform, but only i386 and arm have optimized versions. Other
platforms' copies of in_cksum.c are identical except for style
differences and support for big-endian CPUs.

Deduplicate the implementations for the rest of the platforms. This
will make it easier to implement in_cksum() for unmapped mbufs. On arm
and i386, define HAVE_MD_IN_CKSUM to mean that the MI implementation is
not to be compiled.
