Guo, this is a really nice work, and I'm looking forward having generic
entry support for RV. However, there are many patches in this series
that really shouldn't be part of the series.

Patch 2, 3, 4, and 10 should defintely be pulled out.

I'm not sure 7, 8, and 9 belong to series, as it's really a separate
feature.

Dito for patch 11, it just makes the series harder to review.

For GENERIC_ENTRY support only patch 1, 5, 6, 12, 13, and 14, really
required. The others are unrelated.


Thanks,
Björn
