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

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. Change-Id: I9354d2e0dc47c689296a34b5b229fc9ba75f1a83

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

Fix x86 cfi directives for syscalls. The syscall generation always used 4 bytes for each push cfi directive. However, the first push should always use an offset of 8 bytes, each subsequent push after that is only 4 bytes though. Change-Id: Ibaabd107f399ef67010b9a08213783957c2f74a9
