MIPS: elfcore: add correct copy_regs implementations
MIPS does not currently define ELF_CORE_COPY_REGS macros and as a result the generic implementation is used. The generic version attempts to do directly map (struct pt_regs) into (elf_gregset_t), which isn't correct for MIPS platforms and also triggers a BUG() at runtime in include/linux/elfcore.h:16 (BUG_ON(sizeof(*elfregs) != sizeof(*regs))) [ralf@linux-mips.org: Add semicolons to the macro definitions as I do not apply https://patchwork.linux-mips.org/patch/14588/ for now.] Signed-off-by: Marcin Nowakowski <marcin.nowakowski@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/14586/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
