From 6c34f1f5424395994c125f8c68bed395920ecc58 Mon Sep 17 00:00:00 2001 From: Kyle McMartin Date: Tue, 16 Sep 2014 22:37:18 +0100 Subject: aarch64: filter $x from kallsyms Similar to ARM, AArch64 is generating $x and $d syms... which isn't terribly helpful when looking at %pF output and the like. Filter those out in kallsyms, modpost and when looking at module symbols. Seems simplest since none of these check EM_ARM anyway, to just add it to the strchr used, rather than trying to make things overly complicated. initcall_debug improves: dmesg_before.txt: initcall $x+0x0/0x154 [sg] returned 0 after 26331 usecs dmesg_after.txt: initcall init_sg+0x0/0x154 [sg] returned 0 after 15461 usecs Signed-off-by: Kyle McMartin Acked-by: Rusty Russell Signed-off-by: Catalin Marinas --- scripts/kallsyms.c | 2 +- scripts/mod/modpost.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'scripts') diff --git a/scripts/kallsyms.c b/scripts/kallsyms.c index dc7aa45e80ce..c6d33bd15b04 100644 --- a/scripts/kallsyms.c +++ b/scripts/kallsyms.c @@ -84,7 +84,7 @@ static void usage(void) */ static inline int is_arm_mapping_symbol(const char *str) { - return str[0] == '$' && strchr("atd", str[1]) + return str[0] == '$' && strchr("axtd", str[1]) && (str[2] == '\0' || str[2] == '.'); } diff --git a/scripts/mod/modpost.c b/scripts/mod/modpost.c index 091d90573b63..3017ec20e9f8 100644 --- a/scripts/mod/modpost.c +++ b/scripts/mod/modpost.c @@ -1146,7 +1146,7 @@ static Elf_Sym *find_elf_symbol(struct elf_info *elf, Elf64_Sword addr, static inline int is_arm_mapping_symbol(const char *str) { - return str[0] == '$' && strchr("atd", str[1]) + return str[0] == '$' && strchr("axtd", str[1]) && (str[2] == '\0' || str[2] == '.'); } -- cgit v1.2.3-58-ga151
