[PATCH v2 00/23] Introduce MMU_INDEX()

[Helge Deller]

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.
