[RFC][PATCH 33/34] x86/cpu: Make get_cpu_address_sizes() static and __init

From: Dave Hansen
Date: Thu Feb 22 2024 - 13:50:32 EST



From: Dave Hansen <dave.hansen@xxxxxxxxxxxxxxx>

Now that all the other users are gone and the final user is in the same file
and __init, get_cpu_address_sizes() can be static and __init.
