Same kind of comment as the other soft mask stuff. Again not a big deal
but there might be a way to improve it. For example make a
debug_syscall_entry(regs) function that ppc64 could put the soft mask
checks into.
No big deal, if you don't make any changes now I might see about doing
something like that after your series goes in.
