This patchset introduces the new helper macro MMU_INDEX().
whill will (after applying the last patch) allow to generate
smaller code by the tcg.
Patch #1 adds the MMU_INDEX() helper macro, which simply wraps
the given value.
Patches #2-#23 are trivial patches which convert each target to use the MMU_INDEX()
macro.
Patch #24 switches MMU_INDEX() to return a new MMU idx which
is counts down from (NB_MMU_MODES-1). That change reduces the needed
negative offset to access the TLB entry which in turn let the tcg compiler
generates smaller instructions.
Please review.
