Paolo,
Here's the first set of fixes for 6.1. The most interesting bit is
Oliver's fix limiting the S2 invalidation batch size the the largest
block mapping, solving (at least for now) the RCU stall problems we
have been seeing for a while. We may have to find another solution
when (and if) we decide to allow 4TB mapping at S2...
The rest is a set of minor selftest fixes as well as enabling stack
protection and profiling in the VHE code.
Please pull,
M.
