Subject: [Qemu-devel] [PATCH 4/6 v7] linux-user: Support tilegx architecture in syscall
Date: Fri, 20 Mar 2015 23:27:56 +0800	[thread overview]
Message-ID: <BLU436-SMTP23580C2FFC82D1D7ABE322B90E0@phx.gbl> (raw)
In-Reply-To: <550C3B78.3050802@hotmail.com>

Add tilegx architecture in "syscall_defs.h", all related features (ioctrl,
and stat) are based on Linux kernel tilegx 64-bit implementation.
