The LVM label is stored on any of the first four sectors, and the
PV (physical volume) header is stored within the same sector following
the LVM label. The current implementation does not fully check the
offset of PV header, when attaching a bad formatted LVM PV the kernel
may crash due to out-of-bounds memory read.

For backward compatibility, the ACPI tables are loaded into the guest
memory. Windows scans the memory, finds the ACPI tables and uses them.
It ignores the ACPI tables provided by the UEFI. We are patching the
ACPI tables in the guest memory, so that's mostly fine. However, Windows
will break when the ACPI tables become to large or when we add entries
which can't be patched by bhyve. One example of an unpatchable entry, is
a TPM log. The TPM log has to be allocated by the guest firmware. As the
address of the TPM log is unpredictable, bhyve can't assign it in the
memory version of the ACPI tables. Additionally, this makes it
impossible for bhyve to calculate a correct checksum of the table.
By default ACPI tables are still loaded into guest memory for backward
compatibility. The new acpi_tables_in_memory config value can be set to
false to avoid this behaviour.

Notably, define AES_ASM which is required for any AES acceleration
(OpenSSL 1.0 gated all AES acceleration on OPENSSL_CPUID_OBJ instead).
Enabling this exposed that new assembly files added in OpenSSL 3.0
needed to be included in the build (aes-x86-64.S and aes-586.S). Both
of these files supplant both aes_core.c and aes_cbc.c. The last file
had to be moved out of the MI SRCS line for aes and into each ASM_*
for non-x86.
As part of this I audited the generated configdata.pm for amd64, i386,
and aarch64 and found the following additional discrepecancies that are
fixed here as well:
- Enabled BSAES_ASM on amd64 which requires bsase-x86_64.S
- Enabled WHIRLPOOL_ASM on amd64 (asm sources already built)
- Enabled CMLL_ASM on amd64 and i386 (asm sources already built)
aarch64 had no discreprecancies in configdata.pm, and no *.pl asm
generators were missing for aarch64 in Makefile.asm. I did not check
powerpc or armv7, but for armv7 all of the asm generators seem to be
present in Makefile.asm.

We can end up with a domain having no CPUs capable of receiving I/O
interrupts. This can occur, for example, when all APIC IDs in a given
domain are 256 or greater, and we have no IOMMU.
In this case disable per-domain interrupt support, effectively reverting
to the behaviour before commit a48de40bcc ("Only use CPUs in the
domain the device is attached to for default"). This has a performance
impact but at least allows the system to be functional. It is a stop-
gap until we can rely on the presence of an IOMMU on all x86 platforms.
Thanks to AMD for providing the high-thread-count machine I used for
testing this change, and to cperciva for testing on other hardware.

This changeset adds a baseline implementation of memcmp and bcmp
for amd64. The same code is used for both functions with conditional
code were the behaviour differs (we need more precise output for the
memcmp case).
FreeBSD documents that memcmp returns the difference between the
mismatching characters. Slightly faster code would be possible could
we relax this requirement to the ISO/IEC 9899:1999 requirement of
merely returning a negative/positive integer or zero.
Performance is better than bionic and glibc, except for long strings
were the two are 13% faster. This could be because they use SSE4
ptest which we cannot use in a baseline kernel.

Restructure parts of pctrie code to make it more compatible with the
needs of vm_radix code.
1. End passing function pointers for memory management.
By breaking insertion into two functions, the call for allocating
memory can happen at the top level and be inlined, rather than
happening via an function pointer to a memory allocator.
By changing the remove function slightly, freeing of memory, when
necessary, can happen at the top level and be inlined.
By turning the reclamation code into two functions, one for starting
iteration over to-be-freed nodes and the other continuing it, all the
freeing can happen at the top level and be inlined.
2. Offer a version of remove that does not panic and returns the freed
value (or NULL).
3. Offer a 'replace' operation, to replace one leaf with another that
has the same key.
These are three of the roadblocks that prevent code sharing between
pctrie and vm_radix code.

The method might require resolving and binding symbols, which means
recursing on the bind lock. It is safe to unlock the bind lock,
since we operate on the private object list, and user attempting to
unload an object from the list of not yet fully loaded objects caused
self-inflicted race.
It is similar to how we treat user' init/fini methods.
