From 786d35d45cc40b2a51a18f73e14e135d47fdced7 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 28 Sep 2012 14:31:03 +0930 Subject: Make most arch asm/module.h files use asm-generic/module.h Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela, ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version into asm-generic/module.h for all arches bar MIPS. Also, use the generic definition mod_arch_specific where possible. To this end, I've defined three new config bools: (*) HAVE_MOD_ARCH_SPECIFIC Arches define this if they don't want to use the empty generic mod_arch_specific struct. (*) MODULES_USE_ELF_RELA Arches define this if their modules can contain RELA records. This causes the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be defined by the arch rather than have the core emit an error message. (*) MODULES_USE_ELF_REL Arches define this if their modules can contain REL records. This causes the Elf_Rel mapping to be emitted and allows apply_relocate() to be defined by the arch rather than have the core emit an error message. Note that it is possible to allow both REL and RELA records: m68k and mips are two arches that do this. With this, some arch asm/module.h files can be deleted entirely and replaced with a generic-y marker in the arch Kbuild file. Additionally, I have removed the bits from m32r and score that handle the unsupported type of relocation record as that's now handled centrally.
