ARM: kprobes: Reject probing of all coprocessor instructions
The kernel doesn't currently support VFP or Neon code, and probing of
code with CP15 operations is fraught with bad consequences. Therefore we
don't need the ability to probe coprocessor instructions and the code to
support this can be removed.
The removed code also had at least two bugs:
- MRC into R15 should set CPSR not trash PC
- LDC and STC which use PC as base register needed the address offset by 8
