I am fine with having the CMA config selected whenever someone selects 
INFINIBAND so adding the help text and making it visible are not a must 
per my taste. However, are you fine with changing the **name** of the 
config directive to CONFIG_INFINIBAND_RDMA_CM so its better understood?

As Erez wrote you on the other thread, we must depend on the CMA else a 
user running make rndconfig would be able to produce a config file where 
  INFINIBAND is selected but the CMA (RDMA_ADDR_TRANS) config is not 
selected so linkage will fail.

Or.
