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>

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

Ensure __set_errno is still visible on LP32. The use of the .hidden directive to avoid going via the PLT for __set_errno had the side-effect of actually making __set_errno hidden (which is odd because assembler directives don't usually affect symbols defined in a different file --- you can't even create a weak reference to a symbol that's defined in a different file). This change switches the system call stubs over to a new always-hidden __set_errno_internal and has a visible __set_errno on LP32 just for binary compatibility with old NDK apps. (cherry-pick of 7efad83d430f4d824f2aaa75edea5106f6ff8aae.) Bug: 17423135 Change-Id: I6b6d7a05dda85f923d22e5ffd169a91e23499b7b

AArch64: Fix mmap64() definition for AArch64, X86_64 For 64bit Architectures mmap() is equivalent to mmap64(). This patch maps mmap64() to mmap() in a similar way to other syscalls that differ based on the size of off_t and off64_t Change-Id: If21b21ef71120bad23d9a608d02d4a7de5220a87 Signed-off-by: Serban Constantinescu <serban.constantinescu@arm.com>
