From 83a44a4f47ad20997aebb311fc678a13cde391d7 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 14 Mar 2022 12:48:41 -0700 Subject: x86: Remove toolchain check for X32 ABI capability Commit 0bf6276392e9 ("x32: Warn and disable rather than error if binutils too old") added a small test in arch/x86/Makefile because binutils 2.22 or newer is needed to properly support elf32-x86-64. This check is no longer necessary, as the minimum supported version of binutils is 2.23, which is enforced at configuration time with scripts/min-tool-version.sh. Remove this check and replace all uses of CONFIG_X86_X32 with CONFIG_X86_X32_ABI, as two symbols are no longer necessary. [nathan: Rebase, fix up a few places where CONFIG_X86_X32 was still used, and simplify commit message to satisfy -tip requirements] Signed-off-by: Masahiro Yamada Signed-off-by: Nathan Chancellor Signed-off-by: Peter Zijlstra (Intel) Link: https://lore.kernel.org/r/20220314194842.3452-2-nathan@kernel.org --- sound/core/control_compat.c | 16 ++++++++-------- sound/core/pcm_compat.c | 20 ++++++++++---------- 2 files changed, 18 insertions(+), 18 deletions(-) (limited to 'sound/core') diff --git a/sound/core/control_compat.c b/sound/core/control_compat.c index edff063e088d..d8a86d1a99d6 100644 --- a/sound/core/control_compat.c +++ b/sound/core/control_compat.c @@ -150,7 +150,7 @@ struct snd_ctl_elem_value32 { unsigned char reserved[128];
