[SLP] Drop nuw when add/sub interchange negates a nonzero constant
sub nuw X, C requires X u>= C, but add nuw X, -C requires X u< C, so
nuw must always be dropped on interchange.

comms/ebook2cw: chase addition of libmpg123
From LAME 3.101 July 09 2026
Use external libmpg123 instead of internal mpglib for mpeg decoding
(unix-like systems which use the autotools ("configure; make; make install")
build system). There are years of improvements in libmpg123 which we do not
have in mpglib. Patch by Thomas Orgis of the mpg123 project.
- upstream ebook2cw does not have this change yet
- there is no static library for libmpg123 so remove that from Makefile for now
- fix bogus /usr/local that crept in
- Finally bumped PORTREVISION

Pull s390 fixes from Vasily Gorbik:
- Fix missing array_index_nospec() call in diag310 memory topology code
to prevent speculative execution with a user controlled array index
- Fix get_align_mask() return type to match vm_unmapped_area_info
align_mask, avoiding possible truncation for future larger masks
- Remove empty zcrypt CEX2 files left over after CEX2 and CEX3 driver
removal
- Add build salt to the vDSO so it gets a unique build id, similar to
the kernel and modules

bluetooth: signal devd on netgraph device events
Currently, devd emits events for external adapters only.
Send Netgraph init/disconnect events to devd so the internal adapter's
state could be asserted from userland.

Pull RISC-V fixes from Paul Walmsley:
"The most notable change involves the rseq kselftest common Makefile
(as it is not RISC-V-specific). The basic approach in the patch
appears similar to one used in the KVM and S390 selftests (grep for
LINUX_TOOL_ARCH_INCLUDE and SUBARCH), and the rseq kselftests pass a
quick build test on x86 after this.
- Avoid a null pointer deference in machine_kexec_prepare() that the
IMA subsystem can trigger
- Bypass libc in part of the ptrace_v_not_enabled kselftest to avoid
noise from child atfork handlers that libc might run
- Include Kconfig support for UltraRISC SoCs, already referenced by
some device drivers; and enable it in our defconfig
- Fix the build of the rseq kselftest for RISC-V by borrowing a

[ELF] --discard-{locals,all}: mark local symbols referenced by retained non-SHF_ALLOC sections (#209042)
With --gc-sections, mark() does not scan relocations of retained
non-SHF_ALLOC sections, so local symbols referenced only by such
sections (e.g. .L symbols in .debug_str_offsets referenced by
.debug_info) do not get the USED flag.
-r/--emit-relocs with --discard-{locals,all} would discard the symbols
and rewrite relocations to reference the null symbol, corrupting DWARF
in the output. This is common on RISC-V, where
RISCVELFObjectWriter::needsRelocateWithSymbol returns true, but is also
possible on other targets with --reloc-section-sym=none.
Call markUsedLocalSymbols from the retention loop (introduced by
#209035)
to set the flag.
Fix #160789
[SLP] Fix miscompile from unsafe operand-order normalization
IsCommutative(MainOp) is also true for a Sub/FSub feeding only
fabs/icmp-eq-0, but that doesn't make every lane swappable: a
converted Add/FAdd lane's operand order is fixed to preserve its
value, and swapping it into a native Sub/FSub's layout negates it.
Re-check each lane before swapping instead of trusting MainOp's.
