This is v2 of the patchset. It is *identical* to v1, but v1 missed patches #20-24 since I hit a mail batch limit with my email provider.
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.
