zstd: disable weak-symbol tracing hooks in the kernel
zstd's tracing API (zstd_trace.h) declares ZSTD_trace_compress_begin()
and friends as __attribute__((weak)) externals, gated on the
ZSTD_HAVE_WEAK_SYMBOLS compile-time probe. That probe has covered
x86_64 and i386 since at least zstd 1.5.6, and was extended to aarch64
and riscv in 1.5.7.
In a static kernel image there is no dynamic linker to patch the PLT GOT
entries at runtime. On amd64 the undefined weak symbols resolve directly
to NULL, so the "!= NULL" guard in the zstd source correctly suppresses
every call through the stubs. On aarch64 and riscv the ABI requires
GOT-based indirection for external calls: the PLT stub address is
non-NULL, the guard passes, and the call lands in an uninitialized GOT
slot. Because this happens before exception handlers are in place the
machine resets silently, making the kernel unbootable after the zstd
1.5.7 import.
The upstream-supported suppression is ZSTD_NO_TRACE (zstd_internal.h),

Emacs Lisp ports framework: Overhaul
This overhaul introduces four key changes to the elisp ports framework:
1. Remove support for packaged byte-compiled elisp.
The primary motivation is to remove a large number of flavor-specific
packages and to simplify the ports tree. As an example, supporting
byte-compiled elisp for devel/tablist required six packages, one for
each flavor of editors/emacs and editors/emacs-devel. With over 100
elisp ports and requests for new Emacs flavors, this was
unmanageable.
2. Install configuration to integrate with Emacs's native compilation
machinery, allowing elisp from ports to be compiled into the standard
cache under the user's home directory.
This matches the behavior of GNU ELPA packages and generally results
in a faster experience. Speedups vary depending on the

compat/linprocfs: Update /proc/partitions output
Linux /proc/partitions reports the major/minor pair, the device size in
1K blocks, and the device name. linprocfs still printed obsolete
statistics columns and reported the size in bytes.
Update linprocfs_dopartitions() to emit the Linux-style header and
report provider sizes in 1K blocks.
