+WARNING
+This patch works with gcc versions 9.1+ and with kernel version 4.13+ 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)
+* AMD Family 17h (Zen 2)
+* Intel Silvermont low-power processors
+* Intel Goldmont low-power processors (Apollo Lake and Denverton)
+* Intel Goldmont Plus low-power processors (Gemini Lake)
+* 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 10th Gen Core i7/i9 (Ice Lake)
+* Intel Xeon (Cascade Lake)
+
+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.
+
