└─>Patch physical to virtual translations at runtime
In linux kernel since version 2.6.39 (release Date: 2011-05-18)
Patch phys-to-virt and virt-to-phys translation functions at
boot and module load time according to the position of the
kernel in system memory.
This can only be used with non-XIP MMU kernels where the base
of physical memory is at a 16MB boundary.
Only disable this option if you know that you do not require
this feature (eg, building a kernel for a single machine) and
you need to shrink the kernel to the minimal size.
