Warning messages:

WARNING: arch/x86/kernel/built-in.o(.text+0x7bc2): Section mismatch in reference from the function bad_addr() to the
variable .init.data:early_res
The function bad_addr() references
the variable __initdata early_res.
This is often because bad_addr lacks a __initdata
annotation or the annotation of early_res is wrong.

WARNING: arch/x86/kernel/built-in.o(.text+0x7c3b): Section mismatch in reference from the function bad_addr_size() to
the variable .init.data:early_res
The function bad_addr_size() references
the variable __initdata early_res.
This is often because bad_addr_size lacks a __initdata
annotation or the annotation of early_res is wrong.
