[PATCH] x86: mark some mpspec inline functions as __init

From: Arnd Bergmann
Date: Thu Feb 25 2021 - 06:23:48 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

clang-13 sometimes decides to not inline early_get_smp_config(),
which leads to a link-time warning:

WARNING: modpost: vmlinux.o(.text+0x838cc): Section mismatch in reference from the function early_get_smp_config() to the variable .init.data:x86_init
The function early_get_smp_config() references
the variable __initdata x86_init.
This is often because early_get_smp_config lacks a __initdata
annotation or the annotation of x86_init is wrong.

There are two other functions which may run into the same issue,
so mark all three as __init.
