RE: [v3] x86/tsc: Unset TSC_KNOWN_FREQ and TSC_RELIABLE flags on Intel Bay Trail SoC

[Kumar, Vipul]

Hi Sasha,

As this patch is based on commit f3a02ecebed7 ("x86/tsc: Set TSC_KNOWN_FREQ and TSC_RELIABLE flags on Intel Atom SoCs") which was introduced in 4.14.

So, this patch is not applicable for kernel versions prior to 4.14.

As this patch is under review, can we put it on hold ?

Regards,
Vipul
