└─>Support XIP filesystems on RAM block device
In linux kernel since version 2.6.25 (release Date: 2008-04-16)  
Support XIP filesystems (such as ext2 with XIP support on) on
top of block ram device. This will slightly enlarge the kernel, and
will prevent RAM block device backing store memory from being
allocated from highmem (only a problem for highmem systems).
