From 1842bdfdbac2ec46f2934d8914c874db83dd1344 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Fri, 9 Oct 2015 17:17:17 +0200 Subject: linux-headers: add unistd.h MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New syscalls are not yet widely distributed. Add them to qemu linux-headers include directory. Update based on v4.3-rc3 kernel headers. Exclude mips for now, which is more problematic due to extra header inclusion and probably unnecessary here.
