  "message": "cpu: conditionally re-enable AVX512 support on darwin/amd64\n\nDarwin opmask clobbering bug was fixed in kernel version 21.3.0\nas released in MacOS 12.2.0. This commit resolves issue by\nchecking for Darwin AVX512 support via a sysctl call with the\naddition of a kernel minimum version check.\n\nThe kernel version check is completed without adding new\ndependencies to x/sys/cpu. A sysctl call is accomplished by\ncopying a minimal amount of code from x/sys/unix, to retrieve\nonly the needed KERN_OSRELEASE value. This code is structured\nin the same manner as an existing analogous AIX/PPC64 syscall.\n\nThe resulting dotted version string value is then parsed for\nnumeric comparison with a dependency free function.\n\nAll code in this contribution is structured to ease removal of\nthe special darwin/amd64 codepaths when that OS/arch combination\nis eventually no longer supported by golang.\n\nResolves issue: golang/go#49233, reinstates fix for issue: golang/go#43089\n\nChange-Id: I4755fc8b3865eb6562b0959ecc910e2c46ac6cb4\nReviewed-on: https://go-review.googlesource.com/c/sys/+/620256\nReviewed-by: Keith Randall \u003ckhr@google.com\u003e\nReviewed-by: Keith Randall \u003ckhr@golang.org\u003e\nLUCI-TryBot-Result: Go LUCI \u003cgolang-scoped@luci-project-accounts.iam.gserviceaccount.com\u003e\nReviewed-by: Carlos Amedee \u003ccarlos@golang.org\u003e\nReviewed-by: vsivsi@yahoo.com \u003cvsivsi@yahoo.com\u003e\n",
