===============================

* linux/aarch64/*.h: Include the existing 2 ARM personalities, move
the AArch64 personality to #2.

* defs.h: Copy in the definition of arm_pt_regs and the accessor
macros, so it's possible to build on AArch64 without needing ARM
system headers. Include the existing 2 ARM personalities and make #2
(AArch64) the default.

* syscall.c: (update_personality) Add debug output for AArch64.
(get_scno): On AArch64, determine if we're in ARM or AArch64 mode by
checking the size of the returned uio structure from PTRACE_GETREGSET and
interpret the structure accordingly.
(get_syscall_result): Likewise.
(get_syscall_args): Merge the AArch64 and ARM sections so that on
AArch64 we can fall back to supporting ARM personalities.
(get_error): Likewise.
