We get a build warning about the newly introduced code in intel_pstate_init_cpu() that references an __initconst variable after it has been freed: WARNING: vmlinux.o(.text+0xf9eca2): Section mismatch in reference from the function intel_pstate_init_cpu() to the variable .init.rodata:intel_pstate_hwp_boost_ids The function intel_pstate_init_cpu() references the variable __initconst intel_pstate_hwp_boost_ids. This is often because intel_pstate_init_cpu lacks a __initconst annotation or the annotation of intel_pstate_hwp_boost_ids is wrong. This removes the annotation to keep the variable around at runtime.
