Make the page size 256k.

The kernel will only be able to run applications that have been compiled with '-zmax-page-size' set to 256K (the default is 64K) using binutils later than 2.17.50.0.3, or by patching the ELF_MAXPAGESIZE definition from 0x10000 to 0x40000 in older versions.

Make the page size 256k.

As the ELF standard only requires alignment to support page sizes up to 64k, you will need to compile all of your user space applications with a non-standard binutils settings (see the STDBINUTILS description for details).

Say N unless you know what you are doing.
