Robin Murphy 0a532ea3ef arm64: Implement array_index_mask_nospec() ... Commit 022620eed3 upstream. Provide an optimised, assembly implementation of array_index_mask_nospec() for arm64 so that the compiler is not in a position to transform the code in ways which affect its ability to inhibit speculation (e.g. by introducing conditional branches). This is similar to the sequence used by x86, modulo architectural differences in the carry/borrow flags.
