Vineet Gupta 6128df5be4 ARC: mm: use SCRATCH_DATA0 register for caching pgdir in ARCv2 only ... MMU SCRATCH_DATA0 register is intended to cache task pgd. However in ARC700 SMP port, it has to be repurposed for re-entrant interrupt handling, while UP port doesn't. We currently handle these use-cases using a fabricated #define which has usual issues of dependency nesting and obvious ugliness. So clean this up: for ARC700 don't use to cache pgd (even in UP) and do the opposite for ARCv2. And while here, switch to canonical pgd_offset().
