+ * and three XORs.  Semi-formally, the definition of these tables is:

+ * mds[2][i] = MDS (0 0 q1[i] 0)^T  mds[3][i] = MDS (0 0 0 q0[i])^T
+ * where ^T means "transpose", the matrix multiply is performed in GF(2^8)
+ * represented as GF(2)[x]/v(x) where v(x)=x^8+x^6+x^5+x^3+1 as described
+ * by Schneier et al, and I'm casually glossing over the byte/word

+/* The exp_to_poly and poly_to_exp tables are used to perform efficient
+ * operations in GF(2^8) represented as GF(2)[x]/w(x) where
+ * w(x)=x^8+x^6+x^3+x^2+1.  We care about doing that because it's part of the
+ * definition of the RS matrix in the key schedule.  Elements of that field
+ * are polynomials of degree not greater than 7 and all coefficients 0 or 1,
+ * which can be represented naturally by bytes (just substitute x=2).  In that
+ * form, GF(2^8) addition is the same as bitwise XOR, but GF(2^8)
+ * multiplication is inefficient without hardware support.  To multiply
+ * faster, I make use of the fact x is a generator for the nonzero elements,
+ * so that every element p of GF(2)[x]/w(x) is either 0 or equal to (x)^n for
+ * some n in 0..254.  Note that that caret is exponentiation in GF(2^8),
+ * *not* polynomial notation.  So if I want to compute pq where p and q are
+ * in GF(2^8), I can just say:
+ *    1. if p=0 or q=0 then pq=0
+ *    2. otherwise, find m and n such that p=x^m and q=x^n
+ *    3. pq=(x^m)(x^n)=x^(m+n), so add m and n and find pq
+ * The translations in steps 2 and 3 are looked up in the tables
+ * poly_to_exp (for step 2) and exp_to_poly (for step 3).  To see this
+ * in action, look at the CALC_S macro.  As additional wrinkles, note that
+ * one of my operands is always a constant, so the poly_to_exp lookup on it
+ * is done in advance; I included the original values in the comments so
+ * readers can have some chance of recognizing that this *is* the RS matrix
+ * from the Twofish paper.  I've only included the table entries I actually
+ * need; I never do a lookup on a variable input of zero and the biggest
+ * exponents I'll ever see are 254 (variable) and 237 (constant), so they'll
+ * never sum to more than 491.	I'm repeating part of the exp_to_poly table
+ * so that I don't have to do mod-255 reduction in the exponent arithmetic.
+ * Since I know my constant operands are never zero, I only have to worry
+ * about zero values in the variable operand, and I do it with a simple
+ * conditional branch.	I know conditionals are expensive, but I couldn't
+ * see a non-horrible way of avoiding them, and I did manage to group the
+ * statements so that each if covers four group multiplications. */
