From: Ard Biesheuvel <[email protected]> MIPS supports PC32 relocations like most other architectures, which will be used by kallsyms to make its symbol references visible to the linker.
Given that these are place-relative, they can be ignored by the 'relocs' tool, just like other PC type relocations.
