+Subject: [PATCH] runtime, internal/cpu: fix build for ARM GNU/Linux
+
+Was failing with
+
+../../../libgo/go/internal/cpu/cpu.go:138:2: error: reference to undefined name 'doinit'
+  138 |  doinit()
+      |  ^
+
+Fix it by adding in Go 1.12 internal/cpu/cpu_arm.go, and the code in
+runtime that initializes the values.
+
+Fixes https://gcc.gnu.org/PR88927.
