Both Hyper-V tsc page and Hyper-V tsc MSR code use variable
hv_sched_clock_offset for their sched clock callback and so
define the variable regardless of CONFIG_HYPERV_TSCPAGE setting.

CONFIG_HYPERV_TSCPAGE is gone after my "x86/hyper-v: enable TSC page
clocksource on 32bit" patch. Do we still have an issue to fix?

Yes. Let's get it fixed on older kernels (as such we need to tag this
one for stable). The 32bit TSC patch won't come in before 5.4 anyway.

Vitaly, does can you ack this patch? It might require you to re-spin
your patch.

Hi Sasha:
               Thomas has foled this fix into original patch.
