Subject: [PATCH] riscv: fix sifive and thead section mismatches in errata
Date: Fri, 28 Apr 2023 21:35:30 -0700	[thread overview]
Message-ID: <20230429043530.20503-1-rdunlap@infradead.org> (raw)

When CONFIG_MODULES is set, __init_or_module becomes <empty>, but when
CONFIG_MODULES is not set, __init_or_module becomes __init.
In the latter case, it causes section mismatch warnings:

WARNING: modpost: vmlinux.o: section mismatch in reference: riscv_fill_cpu_mfr_info (section: .text) -> sifive_errata_patch_func (section: .init.text)
WARNING: modpost: vmlinux.o: section mismatch in reference: riscv_fill_cpu_mfr_info (section: .text) -> thead_errata_patch_func (section: .init.text)

It appears that CONFIG_MODULES not set is not tested very much.

Fixes: a8e910168bba ("riscv: implement module alternatives")
Fixes: a35707c3d850 ("riscv: add memory-type errata for T-Head")
