-WARNING
-This patch works with gcc versions 4.9+ and with kernel version 3.15+ and should
-NOT be applied when compiling on older versions of gcc due to key name changes
-of the march flags introduced with the version 4.9 release of gcc.[1]
-
-Use the older version of this patch hosted on the same github for older
-versions of gcc.
-
-FEATURES
-This patch adds additional CPU options to the Linux kernel accessible under:
- Processor type and features  --->
-  Processor family --->
-
-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)
-
-It also offers to compile passing the 'native' option which, "selects the CPU
-to generate code for at compilation time by determining the processor type of
-the compiling machine. Using -march=native enables all instruction subsets
-supported by the local machine and will produce code optimized for the local
-machine under the constraints of the selected instruction set."[3]
-
-MINOR NOTES
-This patch also changes 'atom' to 'bonnell' in accordance with the gcc v4.9
-changes. Note that upstream is using the deprecated 'match=atom' flags when I
-believe it should use the newer 'march=bonnell' flag for atom processors.[2]
-
-It is not recommended to compile on Atom-CPUs with the 'native' option.[4] The
-recommendation is to use the 'atom' option instead.
-
-BENEFITS
-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 && <4.13
-gcc version >=4.9
-
-ACKNOWLEDGMENTS
-This patch builds on the seminal work by Jeroen.[5]
