Jaeden Amero	97cc3b1354	gf128mul: Remove the jump table ... If we're unlucky with memory placement, gf128mul_table_bbe may spread over two cache lines and this would leak b >> 63 to a cache timing attack. Instead, take an approach that is less likely to make different memory loads depending on the value of b >> 63 and is also unlikely to be compiled to a condition.	2018-06-13 12:03:29 +01:00
