+------
+When ptracing system calls (PTRACE_SYSCALL), the pt_regs.trap value contains
+the system call type that can be used to distinguish between sc and scv 0
+system calls, and the different register conventions can be accounted for.

+If the value of (pt_regs.trap & 0xfff0) is 0xc00 then the system call was
