modpost: Amend ppc64 save/restfpr symnames for -Os build

2026-03-04T12:20:24+00:00

[ Upstream commit 3cd9763ce4ad999d015cf0734e6b968cead95077 ]

Building a size optimized ppc64 kernel (-Os), gcc emits more FP
save/restore symbols, that the linker generates on demand into the
.sfpr section. Explicitly allow-list those in scripts/mod/modpost.c,
too. They are needed for the amdgpu in-kernel floating point support.

scripts: generate_rust_analyzer: Add compiler_builtins -> core dep

2026-02-06T15:44:17+00:00

commit 5157c328edb35bac05ce77da473c3209d20e0bbb upstream.

Add a dependency edge from `compiler_builtins` to `core` to
`scripts/generate_rust_analyzer.py` to match `rust/Makefile`. This has
been incorrect since commit 8c4555ccc55c ("scripts: add
`generate_rust_analyzer.py`")

kbuild: Use CRC32 and a 1MiB dictionary for XZ compressed modules

2026-01-11T14:19:15+00:00

commit fbf5892df21a8ccfcb2fda0fd65bc3169c89ed28 upstream.

Kmod is now (since kmod commit 09c9f8c5df04 ("libkmod: Use kernel
decompression when available")) using the kernel decompressor, when
loading compressed modules.

However, the kernel XZ decompressor is XZ Embedded, which doesn't
handle CRC64 and dictionaries larger than 1MiB.

Use CRC32 and 1MiB dictionary when XZ compressing and installing
kernel modules.

kbuild: Use objtree for module signing key path

2026-01-11T14:18:40+00:00

[ Upstream commit af61da281f52aba0c5b090bafb3a31c5739850ff ]

When building out-of-tree modules with CONFIG_MODULE_SIG_FORCE=y,
module signing fails because the private key path uses $(srctree)
while the public key path uses $(objtree). Since signing keys are
generated in the build directory during kernel compilation, both
paths should use $(objtree) for consistency.

This causes SSL errors like:
  SSL error:02001002:system library:fopen:No such file or directory
  sign-file: /kernel-src/certs/signing_key.pem

The issue occurs because:
- sig-key uses: $(srctree)/certs/signing_key.pem (source tree)
- cmd_sign uses: $(objtree)/certs/signing_key.x509 (build tree)

But both keys are generated in $(objtree) during the build.

This complements commit 25ff08aa43e37 ("kbuild: Fix signing issue for
external modules") which fixed the scripts path and public key path,
but missed the private key path inconsistency.

Fixes out-of-tree module signing for configurations with separate
source and build directories (e.g., O=/kernel-out).

gcc-plugins: Remove TODO_verify_il for GCC >= 16

2025-10-15T09:56:20+00:00

commit a40282dd3c484e6c882e93f4680e0a3ef3814453 upstream.

GCC now runs TODO_verify_il automatically[1], so it is no longer exposed to
plugins. Only use the flag on GCC < 16.

kconfig: lxdialog: fix 'space' to (de)select options

2025-08-28T14:26:02+00:00

[ Upstream commit 694174f94ebeeb5ec5cc0e9de9b40c82057e1d95 ]

In case a menu has comment without letters/numbers (eg. characters
matching the regexp '^[^[:alpha:][:digit:]]+$', for example - or *),
hitting space will cycle through those comments, rather than
selecting/deselecting the currently-highlighted option.

This is the behaviour of hitting any letter/digit: jump to the next
option which prompt starts with that letter. The only letters that
do not behave as such are 'y' 'm' and 'n'. Prompts that start with
one of those three letters are instead matched on the first letter
that is not 'y', 'm' or 'n'.

Fix that by treating 'space' as we treat y/m/n, ie. as an action key,
not as shortcut to jump to  prompt.
