3.19.8-ckt15 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------ From: dann frazier <[email protected]> commit 67dfa1751ce71e629aad7c438e1678ad41054677 upstream. 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: module libahci: unsupported RELA relocation: 275 This patch fixes the problem by passing '-mpc-relative-literal-loads' to the compiler.
