Meltdown fixes for RHEL 7, CentOS7, CentOS7 Plus, Proxmox VE 3.10, CloudLinux 6h, CloudLinux 7

[Irina Semenova]

Dear Customers,

We have released patches for Meltdown vulnerability for above-mentioned distributions. Our internal tests, as well as tests with live customers, didn't reveal any crashes.

Systems with AUTO_UPDATE=True (DEFAULT) in /etc/sysconfig/kcare/kcare.conf will automatically update, and no action is needed for them.

You can manually update the server by running:

# /usr/bin/kcarectl --update
