Subject: [patch 0/2] tsc/adjust: Cure suspend/resume issues and prevent TSC
 deadline timer irq storm

Roland reported interesting TSC ADJUST register wreckage on his DELL
machine, which seems to populate that MSR with a random number generator.

Deeper investagation into fixing this wreckage unearthed another special
feature which is designed by Intel: Negative TSC adjuste values cause
interrupt storms on the TSC deadline timer. Further details in patch 2/2

Thanks
