MIPS: Mark check_bugs() as __init
After commit ac7c3e4ff401 ("compiler: enable CONFIG_OPTIMIZE_INLINING
forcibly"), a compiler may choose not to inline a function marked with
just 'inline'. If check_bugs() is not inlined into start_kernel(), which
occurs when building with clang after commit 9ea7e6b62c2b ("init: Mark
[arch_call_]rest_init() __noreturn"), modpost complains with:
WARNING: modpost: vmlinux.o: section mismatch in reference: check_bugs (section: .text) -> check_bugs32 (section: .init.text)
check_bugs() is only called from start_kernel(), which itself is marked
__init, so there would not be any issues at run time. Make it obvious to
modpost that this call chain is safe by marking check_bugs() as __init,
which fixes the warning.
