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.

Move away from the __ARCH_WANT_SYSCALL_NO_AT system calls. Modern architectures only get the *at(2) system calls. For example, aarch64 doesn't have open(2), and expects userspace to use openat(2) instead. Change-Id: I87b4ed79790cb8a80844f5544ac1a13fda26c7b5 2013-10-22 22:28:46 +02:00			`ENTRY(mknodat)`
