[PATCH 01/30] asm-generic: add .data.rel.ro sections to __ro_after_init

[Ard Biesheuvel]

When running in PIC mode, the compiler will emit const structures
containing runtime relocatable quantities into .data.rel.ro.* sections,
so that the linker can be smart about placing them together in a segment
that is read-write initially, and is remapped read-only afterwards. This
is exactly what __ro_after_init aims to provide, so move these sections
together.
