4KiB pages

configname: CONFIG_PAGE_SIZE_4KB

MMU page size
└─>4KiB pages
In linux kernel since version 2.6.12  
This option select the standard 4KiB Linux page size and the only
available option on many architectures. Using 4KiB page size will
minimize memory consumption and is therefore recommended for low
memory systems.
Some software that is written for x86 systems makes incorrect
assumptions about the page size and only runs on 4KiB pages.
