Subject[PATCH v3 0/3] fix function type mismatches in syscall wrappers
From
These patches fix type mismatches in arm64 syscall wrapper
definitions, which trip indirect call checks with Control-Flow
Integrity.

Changes in v3:
- instead of SYSCALL_DEFINE0, just define __arm64_sys_ni_syscall
with the correct type to avoid unnecessary error injection

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
