rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh https://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm

Install kernel-ml and kernel-ml-devel

yum --enablerepo=elrepo-kernel install -y kernel-ml kernel-ml-devel

To show installed kernels run command:

awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg

Set installed kernel as default for grub2 bootloader:

grub2-set-default 0

Reboot system and check kernel version
