CONFIG_HAVE_ARCH_PREL32_RELOCATIONS (not configurable)

configname: CONFIG_HAVE_ARCH_PREL32_RELOCATIONS

Linux Kernel Configuration
└─>General architecture-dependent options
└─>HAVE_ARCH_PREL32_RELOCATIONS
In linux kernel since version 4.2 (release Date: 2015-08-30)  
May be selected by an architecture if it supports place-relative
32-bit relocations, both in the toolchain and in the module loader,
in which case relative references can be used in special sections
for PCI fixup, initcalls etc which are only half the size on 64 bit
architectures, and don't require runtime relocation on relocatable
kernels.
