Linux Kernel Configuration
└─>Transparent Hugepage Support
In linux kernel since version 2.6.38 (release Date: 2011-03-14)  
Transparent Hugepages allows the kernel to use huge pages and
huge tlb transparently to the applications whenever possible.
This feature can improve computing performance to certain
applications by speeding up page faults during memory
allocation, by reducing the number of tlb misses and by speeding
up the pagetable walking.

If memory constrained on embedded, you may want to say N.
