You need very few things to get the syscalls tracing in an arch.
- Support HAVE_ARCH_TRACEHOOK (see arch/Kconfig).
- Have a NR_syscalls variable in <asm/unistd.h> that provides the number
of syscalls supported by the arch.
- Implement arch_syscall_addr() that resolves a syscall address from a
syscall number.
- Support the TIF_SYSCALL_TRACEPOINT thread flags
- Support the TIF_SYSCALL_TRACEPOINT thread flags.
- Put the trace_sys_enter() and trace_sys_exit() tracepoints calls from ptrace
in the ptrace syscalls tracing path.
- Tag this arch as HAVE_SYSCALL_TRACEPOINTS.
