GCC6 (and Linaro's 2015.12 snapshot of GCC5) has a new default that uses adrp/ldr or adrp/add to address literal pools. When CONFIG_ARM64_ERRATUM_843419 is enabled, modules built with this toolchain fail to load: [ 2.156817] module libahci: unsupported RELA relocation: 275 v2: Unconditionally use flag for both kernel and modules, as Ard notes we have no requirement for supporting literals >1 MB away. v3: Drop reference to -mfix-cortex-a53-843419.
