config TRANSPARENT_HUGEPAGE

	bool "Transparent Hugepage Support" if EMBEDDED

	default y

	help

	  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.
