parentIB/uverbs: Have the core code create the uverbs_root_spec (diff)
IB/uverbs: Build the specs into a radix tree at runtime
This radix tree datastructure is intended to replace the 'hash' structure used today for parsing ioctl methods during system calls. This first commit introduces the structure and builds it from the existing .rodata descriptions. The so-called hash arrangement is actually a 5 level open coded radix tree. This new version uses a 3 level radix tree built using the radix tree library. Overall this is much less code and much easier to build as the radix tree API allows for dynamic modification during the building. There is a small memory penalty to pay for this, but since the radix tree is allocated on a per device basis, a few kb of RAM seems immaterial considering the gained simplicity. The radix tree is similar to the existing tree, but also has a 'attr_bkey' concept, which is a small value'd index for each method attribute. This is used to simplify and improve performance of everything in the next patches.
