Bug Description
This is a public version of https:/
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

If the problem is solved, change the tag 'verification- needed- jammy-linux' to 'verification- done-jammy- linux'. If the problem still exists, change the tag 'verification- needed- jammy-linux' to 'verification- failed- jammy-linux' .
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
