AArch64: Autogenerated syscalls for AArch64 This patch adds AArch64 syscalls, autogenerated using: ./libc/tools/gensyscalls.py Change-Id: I1cc60430423ecb52a35448bf2c358b82136b2f16 Signed-off-by: Serban Constantinescu <serban.constantinescu@arm.com> 2013-10-11 00:05:06 +02:00			`/* Generated by gensyscalls.py.

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.
