This is a backport of mainline commit 92e788b74986. 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") Cc: <stable@vger.kernel.org> # 4.3 and earlier Signed-off-by: Will Deacon <will.deacon@arm.com> --- arch/arm64/kernel/setup.c | 4 ++++ 1 file changed, 4 insertions(+) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
