[mlir][Linalg] Promote lhs/rhs when vectorizing conv1D as outerproduct (#179883)
-- vector.outerproduct requires lhs/rhs to have same element type as the
result.
-- This commit adds a fix to promote lhs/rhs to have result's element
type when vectorizing conv1D slice to vector.outerproduct.
-- This is along the similar lines of what happens when we are
vectorizing conv1D slice to vector.contract - the corresponding
CHECK line was incorrect and this commit fixes that too.

kernel - Fix overflow in alist and blist code
* This code tracks swap space and large blocks of contiguous DMA memory.
* Fix overflows in array size calculations that did not take into
account terminator entries.
(a) Remove terminals from alists entirely.
(b) Account for space used by the terminator in blists.

[X86] AMD Zen 6 Initial enablement (#179150)
This patch adds initial support for AMD Zen 6 architecture (znver6):
- Added znver6 CPU target recognition in Clang and LLVM
- Updated compiler-rt CPU model detection for znver6
- Added znver6 to target parser and host CPU detection
- Added znver6 to various optimizer tests
znver6 features: FP16, AVXVNNIINT8, AVXNECONVERT, AVXIFMA (without BMM).

ftp: simplify socket buffer handling to improve performance
Only set the socket buffer sizes if the user explicitly sets the
rcvbuf (SO_RCVBUF) or sndbuf (SO_SNDBUF) to a positive value.
Otherwise leave to the operating system default.
Determine the transfer size based on the socket buffer size
clamped to 1 KiB .. 128 KiB, using using the maximum (128 KiB)
if the socket buffer size is 0 (autodetect).
Improves transfer performance on long fat links.
Bump version to 20260207.

chat/ejabberd: Update to 26.01
Drop NetBSD su patch because upstream merged it!
## Version 26.01
#### Compile and Start
- Remove dependencies, macros and code for Erlang/OTP older than 25
- Require Elixir 1.14 or higher, that's the lowest we can test automatically
- `ejabberdctl`: Support NetBSD and OpenBSD `su` ([#4320](https://github.com/processone/ejabberd/issues/4320))
- `ejabberdctl.template`: Show meaningful error when `ERL_DIST_PORT` is in use
- `ejabberd_app`: Print address and port where listens for erlang node connections
- `Makefile.in`: Add `make relivectl` similar to `relive` but using `ejabberdctl`
#### Databases
- Add db_serialize support in mnesia modules
- Add db serialization to `mod_muc_sql`

CodeGen, Driver: Add -fsanitize-trap-loop option.
This option may be used to opt into infinite loops for failed UBSan and
CFI checks. It causes Clang to generate an llvm.cond.loop intrinsic call
instead of a conditional branch to a trap instruction when generating
code for a conditional trap.

Add llvm.cond.loop intrinsic.
The llvm.cond.loop intrinsic is semantically equivalent to a conditional
branch conditioned on ``pred`` to a basic block consisting only of an
unconditional branch to itself. Unlike such a branch, it is guaranteed
to use specific instructions. This allows an interrupt handler or
other introspection mechanism to straightforwardly detect whether
the program is currently spinning in the infinite loop and possibly
terminate the program if so. The intent is that this intrinsic may
be used as a more efficient alternative to a conditional branch to
a call to ``llvm.trap`` in circumstances where the loop detection
is guaranteed to be present. This construct has been experimentally
determined to be executed more efficiently (when the branch is not taken)
than a conditional branch to a trap instruction on AMD and older Intel
microarchitectures, and is also more code size efficient by avoiding the
need to emit a trap instruction and possibly a long branch instruction.
On i386 and x86_64, the infinite loop is guaranteed to consist of a short
conditional branch instruction that branches to itself. Specifically,
