From 0dc690e4ef5b901e9d4b53520854fbd5c749e09d Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Tue, 15 Feb 2022 13:41:03 +0100 Subject: asm-generic: Define 'func_desc_t' to commonly describe function descriptors We have three architectures using function descriptors, each with its own type and name. Add a common typedef that can be used in generic code. Also add a stub typedef for architecture without function descriptors, to avoid a forest of #ifdefs. It replaces the similar 'func_desc_t' previously defined in arch/powerpc/kernel/module_64.c Signed-off-by: Christophe Leroy Reviewed-by: Kees Cook Acked-by: Arnd Bergmann Acked-by: Helge Deller Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/f1f91b142b3c1082bdc1586ce71c9bac1e75213c.1644928018.git.christophe.leroy@csgroup.eu --- arch/powerpc/include/asm/sections.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'arch/powerpc/include/asm') diff --git a/arch/powerpc/include/asm/sections.h b/arch/powerpc/include/asm/sections.h index 7728a7a146c3..fddfb3937868 100644 --- a/arch/powerpc/include/asm/sections.h +++ b/arch/powerpc/include/asm/sections.h @@ -6,6 +6,10 @@ #include #include +#ifdef CONFIG_HAVE_FUNCTION_DESCRIPTORS +typedef struct func_desc func_desc_t; +#endif + #include extern char __head_end[]; -- cgit v1.2.3
