+         This option builds kernel modules using the large memory model in
+         order to avoid the use of the ADRP instruction, which can cause
+         a subsequent memory access to use an incorrect address on Cortex-A53
+         parts up to r0p4.

+         Note that the kernel itself must be linked with a version of ld
+         which fixes potentially affected ADRP instructions through the
+         use of veneers.
