-Subject: [PATCH 43/93] nospec: Include <asm/barrier.h> dependency
-
-commit eb6174f6d1be16b19cfa43dac296bfed003ce1a6 upstream.
-
-The nospec.h header expects the per-architecture header file
-<asm/barrier.h> to optionally define array_index_mask_nospec(). Include
-that dependency to prevent inadvertent fallback to the default
-array_index_mask_nospec() implementation.
-
-The default implementation may not provide a full mitigation
-on architectures that perform data value speculation.
