- pointer to something in the first four arguments, just
- declare it as a pointer, not u32. On the other side,
- arguments from 5th onwards should be declared as u32
- for pointers, and need AA() around each usage.
- A() macro should be used for places where you e.g.
- have some internal variable u32 and just want to get
- rid of a compiler warning. AA() has to be used in
- places where you want to convert a function argument
- to 32bit pointer or when you e.g. access pt_regs
- structure and want to consider 32bit registers only.
