[PATCH OLK-6.6] kbuild: userprogs: use correct linker when mixing clang and GNU ld
by Tengda Wu 06 Aug '25
by Tengda Wu 06 Aug '25
06 Aug '25
From: Thomas Weißschuh <thomas.weissschuh(a)linutronix.de>
mainline inclusion
from mainline-v6.17
commit 936599ca514973d44a766b7376c6bbdc96b6a8cc
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/ICRNOY
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
The userprogs infrastructure does not expect clang being used with GNU ld
and in that case uses /usr/bin/ld for linking, not the configured $(LD).
This fallback is problematic as it will break when cross-compiling.
Mixing clang and GNU ld is used for example when building for SPARC64,
as ld.lld is not sufficient; see Documentation/kbuild/llvm.rst.
Relax the check around --ld-path so it gets used for all linkers.
Fixes: dfc1b168a8c4 ("kbuild: userprogs: use correct lld when linking through clang")

hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/ICE7WC
--------------------------------
This feature allows users to use CPU quota more flexibly when CPU is
idle and it will cause the CPU quota to be exceeded. So, it cannot be
used in scenarios where there are strict restrictions on the use of the
CPU quota, such as some commercial scenarios that charge based on the
use of CPU quota.
