Sort the syscalls.mk files, give all generated files the same header. No non-comment changes to the .S files. Change-Id: Iafcfd004c3ea92b64268f80ab16df615b97cefac 2013-10-16 23:27:59 +02:00			`/* Generated by gensyscalls.py. Do not edit. */`

Stop using the non-uapi <linux/err.h> header file. We only need it for MAX_ERRNO, and it's time we had somewhere to put the little assembler utility macros we've been putting off writing.

Remove dependencies on obsolete __ARCH_WANT_SYSCALL_NO_FLAGS syscalls. (aarch64 kernels only have the newer system calls.) Also expose the new functionality that's exposed by glibc in our header files. Change-Id: I45d2d168a03f88723d1f7fbf634701006a4843c5 2013-10-23 18:48:29 +02:00			`ENTRY(dup3)`
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`
