From 9b2ffa8d048656baf7f5e764d2586ba59927a25b Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 28 Mar 2012 16:20:20 +0900 Subject: [PATCH] sh: Avoid exporting unimplemented syscalls. Now that userspace is making use of kernel-provided sanitized headers for working out supported interfaces, we need to be a bit more diligent with matching the syscall definitions with their actual wiring/support state. In theory it shouldn't hurt anything since sys_ni_syscall will ultimately do the right thing, but there's also not much need to lie about legacy x86 syscalls that we've never supported. This tightens things up a bit for uClibc at least.
