For quite a while, there has existed a hypervisor bug on legacy iSeries which means that we do not get the boot time set in the kernel. This patch works around that bug. This was most noticable when the root partition needed to be checked at every boot as the kernel thought it was some time in 1905 until user mode reset the time correctly.
