Linux Kernel Configuration
└─>Patch physical to virtual translations at runtime (EXPERIMENTAL)
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, or theoretically 64K
for the MSM machine class.
