From 39a3cb27c123df8e8461291cc9e86f1ac3f0ea06 Mon Sep 17 00:00:00 2001 From: Marcin Nowakowski Date: Mon, 21 Nov 2016 11:23:39 +0100 Subject: [PATCH] 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 Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/14586/ Signed-off-by: Ralf Baechle --- arch/mips/include/asm/elf.h | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/arch/mips/include/asm/elf.h b/arch/mips/include/asm/elf.h index f61a4a14bb56..7a6c466e5f2a 100644 --- a/arch/mips/include/asm/elf.h +++ b/arch/mips/include/asm/elf.h @@ -224,6 +224,9 @@ void mips_dump_regs64(u64 *uregs, const struct pt_regs *regs); */ #define ELF_CLASS ELFCLASS32 +#define ELF_CORE_COPY_REGS(dest, regs) \ + mips_dump_regs32((u32 *)&(dest), (regs)); + #endif /* CONFIG_32BIT */ #ifdef CONFIG_64BIT @@ -237,6 +240,9 @@ void mips_dump_regs64(u64 *uregs, const struct pt_regs *regs); */ #define ELF_CLASS ELFCLASS64 +#define ELF_CORE_COPY_REGS(dest, regs) \ + mips_dump_regs64((u64 *)&(dest), (regs)); + #endif /* CONFIG_64BIT */ /* -- 2.20.1
