This patchseries fixes up our somewhat broken handling of mmu_idx values:
 * implement the full set of 7 mmu_idxes we need for supporting EL2 and EL3
 * pass the mmu_idx in the TB flags rather than EL or a priv flag,
   so we can generate code with the correct kind of access
 * identify the correct mmu_idx to use for AT/ATS system insns
 * pass mmu_idx into get_phys_addr() and use it within that family
   of functions as an indication of which translation regime to do
   a v-to-p lookup for, instead of relying on an is_user flag plus the
   current CPU state
 * some minor indent stuff on the end

It does not contain:
 * complete support for EL2 or 64-bit EL3; in some places I have added
   the code where it was obvious and easy; in others I have just left
   TODO marker comments
 * the 'tlb_flush_for_mmuidx' functionality I proposed in a previous mail;
   I preferred to get the semantics right in this patchset first before
   improving the efficiency later
