all: go fmt ./...
...
Make all our package sources use Go 1.17 gofmt format
(adding //go:build lines).
Not strictly necessary but will avoid spurious changes
as files are edited.
Part of //go:build change (#41184 ).
See https://golang.org/design/draft-gobuild

cpu: read ARM64 registers using sysctl(3) on netbsd/arm64
...
Use sysctl("machdep.cpu0.cpu_id") to retrieve the ARM64 cpu_id
information on netbsd/arm64. This includes the ISAR0, ISAR1 and PFR0
registers which can be parsed using existing functionality.
In order to use sysctl(3) without depending on x/sys/unix, some
functionality needed to be copied and slightly adjusted.

cpu: support reading arm64 CPU feature registers
...
This allows to detect ARM64 CPU features on non-Linux systems. On Linux,
this is used in case /proc/self/auxv cannot be read.

cpu: fix build for GOARCH=arm64 on GOOS!=linux
...
The current implementation for arm64 only supports linux (through HWCaps
read from /proc/self/auxv) and fails to build e.g. on darwin/arm64.
Fixes golang/go#30237
