[PATCH 01/20] powerpc/kernel: Add __init attribute to eligible functions
Nick Child
nnac123 at gmail.com
Thu Dec 16 03:12:24 AEDT 2021
Some functions defined in `arch/powerpc/kernel` (and one in `arch/powerpc/
kexec`) are deserving of an `__init` macro attribute. These functions are
only called by other initialization functions and therefore should inherit
the attribute.
Also, change function declarations in header files to include `__init`.
