Replace Erich Keane as Attributes maintainer (#177005)
During the Clang maintainers list refresh, Erich mentioned he would like
me to resume ownership of Clang attributes due to time constraints.
He'll continue to help out as he can but this frees him up for other
efforts. Thank you for your help in this role!
[clang][ssaf] Fix instantiations of `Registry<TUSummaryExtractor, TUSummaryBuilder &>` (#176730)
This patch fixes the incorrect explicit instantiation
declaration/definition added in #173290, and adds checks to prevent
similar errors.
MinGW/Cygwin with `-DCLANG_LINK_CLANG_DYLIB=ON` require proper
declarations of the template instantiations to share data symbols across
DLL boundaries.
[MLIR][OpenMP] Simplify OpenMP device codegen
After removing host operations from the device MLIR module, it is no longer
necessary to provide special codegen logic to prevent these operations from
causing compiler crashes or miscompilations.
This patch removes these now unnecessary code paths to simplify codegen logic.
Some MLIR tests are now replaced with Flang tests, since the responsibility of
dealing with host operations has been moved earlier in the compilation flow.
MLIR tests holding target device modules are updated to no longer include now
unsupported host operations.
tcp: fix checksum calculation bug
The new function in_delayed_cksum_o() was introduced to compute
the checksum in the case the mbuf chain does not start with the
IP header. The offset of the IP header is specified by the
parameter iph_offset.
If iph_offset was positive, the function computed an incorrect
checksum.

[Flang][OpenMP] Minimize host ops remaining in device compilation
This patch updates the function filtering OpenMP pass intended to remove host
functions from the MLIR module created by Flang lowering when targeting an
OpenMP target device.
Host functions holding target regions must be kept, so that the target regions
within them can be translated for the device. The issue is that non-target
operations inside these functions cannot be discarded because some of them hold
information that is also relevant during target device codegen. Specifically,
mapping information resides outside of `omp.target` regions.
This patch updates the previous behavior where all host operations were
preserved to then ignore all of those that are not actually needed by target
device codegen. This, in practice, means only keeping target regions and mapping
information needed by the device. Arguments for some of these remaining
operations are replaced by placeholder allocations and `fir.undefined`, since
they are only actually defined inside of the target regions themselves.

vtnet: improve consistency
Use sbuf_new_for_sysctl() instead of sbuf_new_auto() when exposing
the flags via sysctl.

vtnet: expose features via sysctl tree
Right now the 64-bit flags field needs to be casted to a 32-bit field,
because clang warns if more than 32-bits are used.
Once clang is fixed, this restriction will be removed and more bits
will be added.

This will be usable after clang has been extended to accept length
