Subject: [PATCH] Always access the instruction pointer intrinsic via macros
This allows architectures that do not really have an instruction pointer,
at least not a visible one, to use 0 instead (as a sentinel/dummy value).
The instruction pointer is used for debugging purposes in general kernel
code. Code that actually uses it as a jump target is arch-specific, and
there is thus no risk in not using the real program counter value.
