Revision eb6174f6d1be16b19cfa43dac296bfed003ce1a6 authored by Dan Williams on 16 February 2018, 21:20:54 UTC, committed by Ingo Molnar on 17 February 2018, 07:40:59 UTC
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.
