[Bug 1562653] Re: Ubuntu 15.10: QEMU VM hang if memory >= 1T

[changlimin]

I delete cdrom and IDE controller, the vm start sucessfully.

But when I increate memory to 1100G, vm hang at hpet_enable when start.

The panic is page_fault when execute   hpet_period =
hpet_readl(HPET_PERIOD);

It seems that ioremap_nocache does not works correctly.

hpet_virt_address = ioremap_nocache(hpet_address, HPET_MMAP_SIZE);
