One open question: At this stage the convenience aliases that you
kept in include/asm/lpae.h are used in a very limited number of places.
I am not sure I would call it very limited:
42sh> ack "(FIRST|SECOND|THIRD)_(ORDER|SHIFT|MASK)" | wc -l
65
That's including the 9 definitions.
Could we remove those and use only XEN_PT_LEVEL_* to make the
code a bit more coherent.
I made an attempt in the past and it resulted to longer line in
assembly. So I am on the fence to whether the aliases should be
completely removed.
At the same time, XEN_PT_LEVEL(...) is handy for places where we don't
know at compile time the level.
Cheers,
