IB/core: Add mitigation for Spectre V1 [ Upstream commit 61f259821dd3306e49b7d42a3f90fb5a4ff3351b ] Some processors may mispredict an array bounds check and speculatively access memory that they should not. With a user supplied array index we like to play things safe by masking the value with the array size before it is used as an index.
