| From | Sami Tolvanen <> | Subject | [PATCH 10/15] arm64: disable ARM64_ERRATUM_843419 for clang LTO | Date | Fri, 3 Nov 2017 10:11:55 -0700 |
| |
CONFIG_CLANG_LTO depends on GNU gold, which can generate ADR_PREL_PG_HI21 relocations even with --fix-cortex-a53-843419.
Since ARM64_ERRATUM_843419 disables kernel support for these relocations, disable the erratum when LTO is used.
