If anyone has any objections, please let me know. ------------------ From: Patrik Jakobsson commit 4f7dfb6788dd022446847fbbfbe45e13bedb5be2 upstream. The Intel PRM says the M1 and M2 divisors must be in the range of 10-20 and 5-9. Since we do all calculations based on them being register values (which are subtracted by 2) we need to specify them accordingly.
