This patch adds additional CPU options to the Linux kernel.
The expanded microarchitectures include:
* AMD Improved K8-family
* AMD K10-family
* AMD Family 10h (Barcelona)
* AMD Family 14h (Bobcat)
* AMD Family 16h (Jaguar)
* AMD Family 15h (Bulldozer)
* AMD Family 15h (Piledriver)
* AMD Family 15h (Steamroller)
* AMD Family 15h (Excavator)
* AMD Family 17h (Zen)
* Intel Silvermont low-power processors
* Intel 1st Gen Core i3/i5/i7 (Nehalem)
* Intel 1.5 Gen Core i3/i5/i7 (Westmere)
* Intel 2nd Gen Core i3/i5/i7 (Sandybridge)
* Intel 3rd Gen Core i3/i5/i7 (Ivybridge)
* Intel 4th Gen Core i3/i5/i7 (Haswell)
* Intel 5th Gen Core i3/i5/i7 (Broadwell)
* Intel 6th Gen Core i3/i5/i7 (Skylake)
* Intel 6th Gen Core i7/i9 (Skylake X)
* Intel 8th Gen Core i3/i5/i7 (Cannon Lake)
* Intel 8th Gen Core i7/i9 (Ice Lake)
