Sort the syscalls.mk files, give all generated files the same header. No non-comment changes to the .S files. Change-Id: Iafcfd004c3ea92b64268f80ab16df615b97cefac

/* Generated by gensyscalls.py. Do not edit. */
Use the correct names for the __ARM_NR_* syscalls. This lets us move all the ARM syscall stubs over to the kernel <asm/unistd.h>. Our generated <sys/linux-syscalls.h> is now unused, but I'll remove that in a later change. Change-Id: Ie5ff2cc4abce1938576af7cbaef615a79c7f310d

Use the kernel's MAX_ERRNO in the syscall stubs. Bug: http://code.google.com/p/android/issues/detail?id=53104 Change-Id: Iaabf7025b153e96dc5eca231a33a32d4cb7d8116

Add extended attribute (xattr) system call wrappers to bionic. The xattr system calls are required for the SE Android userspace in order to get and set file security contexts. In particular, libselinux requires these calls. Change-Id: I78f5eb3d8f3384aed0a5e7c6a6f001781d982017

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.
