Subject: [PATCH 4/8] x86-64, ia32: Move compat_ni_syscall into C and its own file
Date: Thu, 17 Nov 2011 14:37:22 -0800	[thread overview]
Message-ID: <1321569446-20433-5-git-send-email-hpa@linux.intel.com> (raw)
In-Reply-To: <1321569446-20433-1-git-send-email-hpa@linux.intel.com>

From: "H. Peter Anvin" <hpa@linux.intel.com>

Move compat_ni_syscall out of ia32entry.S and into its own .c file.
Although this is a trivial function, it is not performance-critical,
and this will simplify further cleanups.
