+Subject: arm64: restore bogomips information in /proc/cpuinfo
+
+From: Yang Shi <yang.shi@linaro.org>
+
+commit 92e788b749862ebe9920360513a718e5dd4da7a9 upstream.
+
+As previously reported, some userspace applications depend on bogomips
+showed by /proc/cpuinfo. Although there is much less legacy impact on
+aarch64 than arm, it does break libvirt.
+
+This patch reverts commit 326b16db9f69 ("arm64: delay: don't bother
+reporting bogomips in /proc/cpuinfo"), but with some tweak due to
+context change and without the pr_info().
+
+Fixes: 326b16db9f69 ("arm64: delay: don't bother reporting bogomips in /proc/cpuinfo")
