Patch phys-to-virt translation functions at runtime according to
the position of the kernel in system memory.
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 with MMU kernels where
the base of physical memory is at a 16MB boundary.
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.

This option extends the physical to virtual translation patching
to allow physical memory down to a theoretical minimum of 64K
boundaries.
