Jessica Yu c8ebf64eab arm64/module: use plt section indices for relocations ... Instead of saving a pointer to the .plt and .init.plt sections to apply plt-based relocations, save and use their section indices instead. The mod->arch.{core,init}.plt pointers were problematic for livepatch because they pointed within temporary section headers (provided by the module loader via info->sechdrs) that would be freed after module load. Since livepatch modules may need to apply relocations post-module-load (for example, to patch a module that is loaded later), using section indices to offset into the section headers (instead of accessing them through a saved pointer) allows livepatch modules on arm64 to pass in their own copy of the section headers to apply_relocate_add() to apply delayed relocations.
