The following build regressions are noticed on the stable -rc 5.10.240-rc1
with gcc-12 and clang-20 toolchains for the arm, arm64, powerpc and s390.

First seen on the tag 5.10.240-rc1.
Good: 5.10.239
Bad:  5.10.240-rc1

Regression Analysis:
- New regression? Yes
- Reproducibility? Yes

Build regression: arm arm64 powerpc s390 drivers base cpu.c undefined
reference to `cpu_show_tsa'
