m68k: use tracehook_report_syscall_entry/exit for ColdFire MMU ptrace path (8b38f3c9) · Commits · 戴 / test

The existing ColdFire code (which is all non-mmu) for system call entry and exit uses the more modern tracehook_report_syscall_entry()/exit() into the ptrace code. Now that we are supporting ColdFire with MMU we need the same hooks for these. Signed-off-by:
