BugLink: BugLink: https://bugs.launchpad.net/bugs/2054699 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 -- Feng Tang (1): x86/tsc: Extend watchdog check exemption to 4-Sockets platform arch/x86/kernel/tsc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
