From 854dd54245f7f1b1175b1bada613929396a571be Mon Sep 17 00:00:00 2001 From: Renat Valiullin Date: Thu, 13 Oct 2016 11:45:39 -0700 Subject: x86/vmware: Skip timer_irq_works() check on VMware The timer_irq_works() boot check may sometimes fail in a VM, when the Host is overcommitted or when the Guest is running nested. Since the intended check is unnecessary on VMware's virtual hardware, by-pass it.
