netmap: Handle TX buffers larger than MCLBYTES
The generic netmap TX pool always allocates standard clusters
(zone_clust), even though the buffer size may be larger.
INVARIANTS kernels panic in nm_os_get_mbuf() on first transmit through a
non-native NIC (e.g. re or epair) using netmap with jumbo frames
configured. Release kernels silently truncate frames in
nm_os_generic_xmit_frame().
Implement cluster zone selection based on the requested size. Catch
oversized requests in nm_os_catch_tx() and return EINVAL. Add a KASSERT
before the truncation fallback in xmit. Make nm_os_get_mbuf() take a
uint32_t size, matching the type of the value passed to it.
Tested using epair, pkt-gen, and tcpdump on release (15.1) and
INVARIANTS (main) kernels at buffer sizes 2048/4096/9216/16384.

[LoongArch] Load suitable immediates with LU12I.W+SLLI.D (#242357)
In V8[^0] and (in the future) SpiderMonkey[^1], immediates with fewer
than 19 significant bits in the upper word and all zeros in the lower
word are loaded with `LU12I.W; SLLI.D`. This shortens the current
loading sequence by 1 instruction. It especially benefits large
constants like NaN, floating-point constants, large addresses, etc.
A bonus effect is that many FP loads that originally go through constant
pools can now enjoy immediate loading with `LU12I.W; SLLI.D; MOVGR2FR.D`
and others. (See also the test changes for this.)

[LoongArch] Properly mask bits of LU{32,52}I.D in foldLargeOffset() (#242356)
`LU32I.D` sets the upper 32 bits by sign extension, and `LU52I.D` sets
the upper 12 bits[^0]. However, the current code only *toggles* bits
32--51 for `LU32I.D`, and bits 52--63 for `LU52I.D`. This leads to two
problems:
1. `LU32I.D` under-masks.
2. Bits toggled off by any of these two instructions that come first
will be toggled back on by the next.
Since the ranges of `LU32I.D` and `LU52I.D` overlap, both problems would
manifest.
Fix this by extending the upper bound of `LU32I.D`'s range to bit 63,
and using `Mask &= ~PATTERN`.

devel/jsonnet: Update to 0.22.0
- Build with USE_SYSTEM_RAPIDYAML, so jsonnet keeps the system

necessary.
- Add two upstream fixes for USE_SYSTEM_RAPIDYAML: the find_package()
call for ryml, and the ryml_std.hpp include in vm.cpp.
- Remove the patches for files that upstream removed or changed.
- Do not build the man pages. They need help2man.
The new CMakeLists.txt requires CMake 3.15 or later, so the port builds
with CMake 4.

[mlir][scf] Compare vector reads and writes fully in parallel loop fusion (#241398)
`scf-parallel-loop-fusion` fuses a loop that writes a buffer with a later loop that reads it, when each iteration reads only what the same iteration of the first loop wrote. For vector reads it didn't check this fully: it ignored the vector types, the permutation maps, and a `vector.mask` around the write. A scalar `memref.load` after a masked `vector.transfer_write` had the same gap. After fusion, such a read can see elements before another iteration writes them.
For example, a `vector<1xf32>` write and then a `vector<4xf32>` read at the same index:
```mlir
func.func @xfer_type(%A: memref<8xf32>, %B: memref<8xf32>) {
%c0 = arith.constant 0 : index
%c1 = arith.constant 1 : index
%c5 = arith.constant 5 : index
%pad = arith.constant 0.0 : f32
%one = arith.constant dense<1.0> : vector<1xf32>
scf.parallel (%i) = (%c0) to (%c5) step (%c1) {
vector.transfer_write %one, %A[%i] {in_bounds = [true]} : vector<1xf32>, memref<8xf32>
scf.reduce
}
scf.parallel (%i) = (%c0) to (%c5) step (%c1) {
%r = vector.transfer_read %A[%i], %pad {in_bounds = [true]} : memref<8xf32>, vector<4xf32>

[libc][math] Add coshbf16 math function (#240859)
Closes #233065. Part of #177259.
Adds `coshbf16`, built on the shared `sinhcoshbf16_utils.h` helpers that
landed with `sinhbf16` (#224645). It computes
`eval_sinh_or_cosh</*IsSinh=*/false>` in the middle range and
`exp_half(|x|)` for |x| >= 6.875, and handles these cases directly:
- |x| <= 0x1.68p-4 rounds to 1 (or to the next value above 1 in RU).
- |x| >= 89.5 overflows to +Inf.
- NaN and Inf.
Testing:
- The exhaustive MPFR test (all bf16 inputs, all rounding modes, 0.5
ULP) passes.
- The smoke and shared-math tests pass.
Bazel targets are included, mirroring `sinhbf16`, but I haven't built
them locally.

[flang] Cache host variable lists for global captures (#240308)
This change addresses redundant work when lowering internal procedures
that access host globals: each internal procedure rebuilds the same host
variable list and reruns dependency analysis.
It caches the ordered variable list and selects the captured globals and
their EQUIVALENCE storage once per host. The list is reused when
lowering the host, and the selected bindings are reused by its internal
procedures in their original list order.
The cached host list and binding pointers are released after all entry
points and internal procedures have been lowered to bound retained
memory.
Tests cover host-associated scalar and EQUIVALENCE bindings across MAIN
and procedure scopes, including module storage, multiple internal
procedures and ENTRY points, zero-sized storage collisions, and mixed
EQUIVALENCE/THREADPRIVATE captures.

[X86] Enable SlotIndexes compaction by default
Compacting SlotIndexes before greedy allocation drops the entries of
erased instructions, so live range sizes and instruction distances
reflect the code being allocated rather than how much was erased
before it. AMDGPU has done this since #235806; do the same for X86.
Codegen changes only through allocation: no new crashes, verifier
errors or allocation failures in the lit suites, including
EXPENSIVE_CHECKS, and a stage-2 build of LLVM, clang and lld with
-verify-machineinstrs passes its own tests. On llvm-test-suite at -O3,
spills drop 0.3% and .text 0.06%, with compile time unchanged.
Most test updates are regenerated checks. misched-matmul now inserts
20 spills instead of 24. live-debug-vars-stale-slotindexes.mir gets
one more use of %27 so that accumulate_fit still reaches the stale
index path it was written for.
[X86][APX] Test the relocation of an NF add
test_regclass_not_updated_by_regalloc_2 only produced an NDD/NF add
with a GOT operand because the allocator happened to give the add a
destination different from its source. With SlotIndexes compaction it
picks the same register, so the add is compressed to the legacy form
and the CODE_6 TODO lost its test.
Add a function whose add keeps its source live, so it stays NDD and
becomes NF under any allocation.
