[PATCH for-7.2 00/21] accel/tcg: minimize tlb lookups during translate + user-only PROT_EXEC fixes

[Richard Henderson]

This is part of a larger body of work, but in the process of
reorganizing I was reminded that PROT_EXEC wasn't being enforced
properly for user-only.  As this has come up in the context of
some of Ilya's patches, I thought I'd go ahead and post this part.
