These patches fix type mismatches in arm64 syscall wrapper
definitions, which trip indirect call checks with Control-Flow
Integrity.

Changes in v2:
- more informative commit message for the syscall_fn_t change
- added a patch for fixing sys_ni_syscall

Sami Tolvanen (3):
  arm64: fix syscall_fn_t type
  arm64: use the correct function type in SYSCALL_DEFINE0
  arm64: use the correct function type for __arm64_sys_ni_syscall
