Public bug reported:
This is a public version of https://bugs.launchpad.net/bugs/2044822
SRU Justification:
[Impact]
Fix tsc clocksource on 4 sockets x86 servers was wrongly judged as 'unstable'
by 'jiffies' and other watchdogs, and disabled
[Fix]
cherry-pick
233756a640be x86/tsc: Extend watchdog check exemption to 4-Sockets platform
from upstream fixes this
[Test Plan]
This has been tested by intel, and has been upstreamed for a while.
[Where problems could occur]
This is a fairly narrow change, and extends a behaviour correction to cover up
to 4-socket machines, rather than just 2 socket machines
