256KiB pages

configname: CONFIG_PAGE_SIZE_256KB

MMU page size
└─>256KiB pages
In linux kernel since version 3.1 (release Date: 2011-10-24)  
256KiB pages have little practical value due to their extreme
memory usage. The kernel will only be able to run applications
that have been compiled with '-zmax-page-size' set to 256KiB
(the default is 64KiB or 4KiB on most architectures).
