From dce0aa3b2ef28900cc4c779c59a870f1b4bdadee Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin (Intel)" Date: Mon, 10 May 2021 11:53:12 -0700 Subject: x86/syscall: Unconditionally prototype {ia32,x32}_sys_call_table[] Even if these APIs are disabled, and the arrays therefore do not exist, having the prototypes allows us to use IS_ENABLED() rather than using #ifdefs. If something ends up trying to actually *use* these arrays a linker error will ensue. Signed-off-by: H.
