    Subject[PATCH 3.14 59/59] arm64: restore bogomips information in /proc/cpuinfo
    Date
    3.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    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")
