Add unshare() syscall. Bug: 6925012 Change-Id: I2530a8f6cea49eb32b60f8f9c4d86963773456ca 2012-08-10 20:17:59 +02:00			`/* autogenerated by gensyscalls.py */`

arm syscall : for eabi call_default don't use stack In the default case, we don't need to use the stack, we can save r7 with ip register (that what does eglibc). This allow to fix vfork data corruption (see 3884bfe9661955543ce203c60f9225bbdf33f6bb), because vfork now don't use the stack. 2013-01-16 14:02:50 +01:00			`mov ip, r7`
