rge: make rx_process_limit a sysctl tunable
The number of packets processed per interrupt was hardcoded to 16.
Add a per-interface sysctl dev.rge.%d.rx_process_limit tunable so
users can adjust this value at runtime.

rge.4: fix incorrect speed range in HARDWARE section
The HARDWARE section stated "PCIe 1GB to 1GB Ethernet devices"
which is incorrect. The RTL8125/8126/8127 chips support speeds
from 1Gbps to 10Gbps. Correct the range.

rge.4: note that the driver manages PHY directly
The rge(4) driver does not use the miibus(4) interface for PHY
management. Instead, it accesses PHY registers directly via the
chip's OCP (On-Chip Peripheral) bus. Document this in the
DESCRIPTION section.

[flang][acc] Handle fir.undefined with OutlineRematerializationOpInterface in OffloadLiveInValueCanonicalization (#188325)
Example:
```fortran
!$ACC KERNELS PRESENT(CG, W1)
CG(1:W1%WDES1%NPL, NN) = W1%CPTWFP(1:W1%WDES1%NPL)
CPROJ(:, NN) = W1%CPROJ(1:SIZE(CPROJ,1))
!$ACC END KERNELS
```
When compiling OpenACC kernels containing array section assignments of
rank-2 arrays with a scalar index in one dimension (e.g. `CG(1:NPL,
NN)`), the Fortran lowering creates a `fir.slice` where collapsed
(scalar) dimensions use `fir.undefined index` as the stop/step values.
`SliceOp::getOutputRank()` relies on `getDefiningOp()` returning
`fir::UndefOp` to identify these collapsed dimensions and compute the
correct output rank.
When `fir.undefined` values defined outside an offload region are used

[libc] Wrong guards for `totalorderbf16` and `totalordermagbf16` (#188241)
Currently the guards for `totalorderbf16` and `totalordermagbf16` are as
follows:
```
#ifndef LLVM_LIBC_SRC_MATH_TOTALORDERMAGF16_H
#define LLVM_LIBC_SRC_MATH_TOTALORDERMAGF16_H
-
#endif // LLVM_LIBC_SRC_MATH_TOTALORDERMAGF16_H
```
and
```
#ifndef LLVM_LIBC_SRC_MATH_TOTALORDERF16_H
#define LLVM_LIBC_SRC_MATH_TOTALORDERF16_H
-
#endif // LLVM_LIBC_SRC_MATH_TOTALORDERF16_H
```
As we can see these are for F16 and not BF16 .
This Pr intends to fix that with correct guards as `TOTALORDERBF16` and
`TOTALORDERMAGBF16`

realpath: Improve prev_len logic
* Save prev_len after having checked for and appended a trailing slash,
not before. This requires us to back up if we end up returning a
partial result, but previously we would sometimes return a partial
result with a trailing slash and sometimes without.
* Replace strlcat() with a faster strlcpy() since we know exactly how
far into the buffer we are.

* Stop abbreviating macro names half-randomly to 8 chars, this is no

* Likewise for function names (in particular use doindex for a function
that is notably different from the classic index function).
* Rename a few things for more fidelity: eval is the builtin name, not
expr and your maketemp/mkstemp conform to mkstemp semantics for better
security.
* Rewrap a few comments that were ludicrously short.
No functional changes except improved accuracy of some error messages.

[lld][WebAssembly] Propagate +atomics for ThinLTO when using --shared-memory (#188381)
When compiling WebAssembly with ThinLTO, functions are partitioned into
isolated `.bc` modules and dispatched to individual LTO backend threads.
During code generation, the `CoalesceFeaturesAndStripAtomics` pass
iterates over the module to gather the union of target features (like
`+atomics`) attached to defined functions. In particular when not using
threads, it lowers away atomics and TLS variables to their
single-threaded equivalents.
However, if a partitioned module only contains globally defined TLS
variables (e.g. there are no functions, or all functions were fully
inlined or stripped by dropDeadSymbols before ThinLTO optimization), the
module becomes completely devoid of function definitions. The coalescing
pass then falls back to fetching features from the `TargetMachine`.
Because in LTO the `TargetMachine` defaults to a generic target without
atomics enabled, the TLS is lowered away and the `wasm-feature-atomics`
flag is omitted from the resulting ThinLTO object partition, causing
`wasm-ld` to immediately reject it.
