Revision 8fa80c503b484ddc1abbd10c7cb2ab81f3824a50 authored by Will Deacon on 05 February 2018, 14:16:06 UTC, committed by Ingo Molnar on 15 February 2018, 00:15:51 UTC
For architectures providing their own implementation of
array_index_mask_nospec() in asm/barrier.h, attempting to use WARN_ONCE() to
complain about out-of-range parameters using WARN_ON() results in a mess
of mutually-dependent include files.

Rather than unpick the dependencies, simply have the core code in nospec.h
perform the checking for us.
