└─>Kernel options
└─>64k page size
In linux kernel since version 2.6.15 (release Date: 2006-01-02)  
This option changes the kernel logical page size to 64k. On machines
without processor support for 64k pages, the kernel will simulate
them by loading each individual 4k page on demand transparently,
while on hardware with such support, it will be used to map
normal application pages.
