-This patch has been tested on and known to work with kernel versions from 3.2
-up to the latest git version (pulled on 12/14/2013).
-
-This patch will expand the number of microarchitectures to include new
-processors including: AMD K10-family, AMD Family 10h (Barcelona), AMD Family
-14h (Bobcat), AMD Family 15h (Bulldozer), AMD Family 15h (Piledriver), AMD
-Family 16h (Jaguar), Intel 1st Gen Core i3/i5/i7 (Nehalem), Intel 2nd Gen Core
-i3/i5/i7 (Sandybridge), Intel 3rd Gen Core i3/i5/i7 (Ivybridge), and Intel 4th
-Gen Core i3/i5/i7 (Haswell). It also offers the compiler the 'native' flag.
-
-Small but real speed increases are measurable using a make endpoint comparing
-a generic kernel to one built with one of the respective microarchs.
-
-See the following experimental evidence supporting this statement:
-https://github.com/graysky2/kernel_gcc_patch
-
-REQUIREMENTS
-linux version >=3.15
-gcc version <4.9
