Now I'm working on LXRT. After that I will look in more detail into the performance issues.
That is a good news, as having the possibility of finally running LXRT on a non x86 arch will be an important improvement. It will allow a better streamlining of many ix86 biased points.
First hint: mind if the process stack addr space is reacheable directly from the kernel as on ix86. Such a trick is exploited in a few places to avoid copy_from/to user space and knowing it exists might avoid you a few questions (headacks? :-)
