HAVE_FTRACE_SYSCALLS
HAVE_SYSCALL_TRACEPOINTS
---------------------
<details to be filled>
You need very few things to get the syscalls tracing in an arch.
- 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
- 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.
