BTW, the question is: which Linux distributions have binary kernels 
compiled w/increased RLIMIT_MEMLOCK value ?

It's necessary for work with Infiniband/OFED environment. And AFAIK 
it's therefore necessary (for increase of this value) to recompile the 
kernel: increasing of the corresponding value in 
/etc/security/limits.conf can't help. 

But (liked by me) OpenSuSE distros, for example, have 
RLIMIT_MEMLOCK=32 only (although I didn't check versions after 10.1).
