Subject: [RESEND PATCH 4/6] x86/unistd: define X32_NR_syscalls only for 64-bit kernel
Date: Mon, 17 May 2021 16:38:12 +0900 [thread overview]
Message-ID: <20210517073815.97426-5-masahiroy@kernel.org> (raw)
In-Reply-To: <20210517073815.97426-1-masahiroy@kernel.org>
X32_NR_syscalls is needed only when building arch/x86/entry/common.c
for x86_64 kernel. It is not used for i386 kernel.
Move it to the else part of #ifdef CONFIG_X86_32.
