hwpmc: fix IBS fetch and op NMI handling
Service each IBS unit with a valid bit set when fetch and op share an
NMI. Otherwise, op samples can be lost. Treat the extra NMI that follows
as expected (skip it).

ipmi: Add some additional diagnostic output on errors
Add some additional diagnostic output for IPMI code,
particularly on error paths. This has been found to be helpful at
$WORK and seems generally useful, so contributing the changes back to
upstream.

math/metis: switch integers size to 32 bits by default
Previously we had INTSIZE64 (and -fdefault-integer-8 for Fortran)
on 64 bits archs, but most consumers programs expect 32 bits
integers by default, and this causes more problems than benefits.
64 bits integers are used only for matrices with more than 2³¹
unknowns, which is not the common case!
llvm: add LoongArch target support, not enabled by default
Note there is ongoing work to add LoongArch support to the base system,
but having target support in llvm is an essential component.
This must be explicitly enabled using WITH_LLVM_TARGET_LOONGARCH.

bhyve: fix boot device ordering
EDK2's QemuBootOrderLib inspects the bootorder file provided
via fw_cfg and requires it to be NUL-terminated. Otherwise,
it rejects the supplied bootorder and falls back to its
default boot order.
Currently, bhyve registers bootorder with qemu_fwcfg_add_file()
using bootorder_len returned by open_memstream(), which excludes
the trailing NUL byte.
Fix that by passing bootorder_len + 1 to qemu_fwcfg_add_file() so
the fw_cfg payload is properly NUL-terminated.

libkvm: support powerpc64 radix minidumps
PowerPC64 radix minidumps use a 64KB root directory followed by three
levels of 4KB page tables. Add an MMU backend which walks those tables,
handles large-page leaves, and decodes their always-big-endian entries
on both powerpc64 and powerpc64le.
Reject old radix minidumps whose pmap section is empty with a specific
diagnostic. Add a synthetic powerpc64le dump test which reads a page
through both its kernel and direct-map addresses.

powerpc/radix: include page tables in minidumps
The radix pmap did not implement the minidump pmap callbacks, so radix
minidumps were emitted with an empty pmap section. Such dumps do not
contain enough information for libkvm to translate kernel virtual
addresses.
Snapshot the 64KB radix root table in the pmap section, add lower-level
page-table pages to the sparse dump, and include pages backing non-DMAP
kernel mappings. Keep the bulk direct map out of the dump while
retaining the relocated kernel image.

arm: pad minidump page table
libkvm locates the sparse page array after the page-rounded PTE table
size, but the ARM minidump writer emitted only the unrounded size. When
the table size was not page-aligned, libkvm therefore read every dumped
physical page at the wrong offset.
The mismatch was introduced when libkvm began rounding ptesize. It has
affected ARM minidumps since ffdeef323449 ("libkvm: Improve physical
address lookup scaling."). It is exposed when the dumped KVA span is not
a multiple of 4 MiB.
Zero-pad the final PTE page and include the padding in the dump size.

powerpc/radix: synchronize temporary kernel mappings
The radix kremove implementation cleared a kernel PTE without
invalidating its TLB entry. Reusing crashdumpmap could therefore keep
accessing an old physical page, causing minidumps to contain repeated
stale page contents.
Invalidate the removed kernel mapping and synchronize newly installed
kernel PTEs before they are accessed.
