That is the conclusion I came to in:

Saving in the PT_SCRATCH area (pad0 in C) was a solution for 2.4. Unfortunately, syscall arguments are stored there (and that's why pad0 exists in pt_regs after all). So, using PT_SCRATCH as a temporary storage for t2 will break tracing syscalls with more than 4 args for o32 ABI.
