[Qemu-devel] [PATCH 03/10 v10] linux-user/syscall.c: Conditionalize sysc


From: Chen Gang
Subject: [Qemu-devel] [PATCH 03/10 v10] linux-user/syscall.c: Conditionalize syscalls which are not defined in tilegx
Date: Mon, 11 May 2015 06:40:07 +0800
User-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:31.0) Gecko/20100101 Thunderbird/31.6.0

Some of architectures (e.g. tilegx), several syscall macros are not
supported, so switch them.
