Commit 13d5097 (kvm tools: Fix reported year in RTC emulation)
attempted to fix wrongly reported RTC year. However, as pointed out by
hpa the proper way to deal with this is to support the RTC century
field.

no, just a security since kvm checks it.
Anyway you can ignore this patch if you want.

Description:
This patch set make the readonly memory in qemu really readonly by using
readonly memory slots feature in kvm to make qemu-kvm safer. Memory
regions with readonly property would be plug into kvm as readonly memory
slots.
Below module can test this feature:
static int rom_tester_probe(struct
let it not depend on __KVM_HAVE_READONLY_MEM to make it friendly
to userspace

In isapc, no i440x device exists in guest that means seabios can not
make 0xc to 0x100 writable
It works fine in current code since the guest can happily write readonly
memory. In order to support readonly slot in Qemu, we do not make the bios
readonly anymore

As readonly memory is support in kvm, this patch supports this feature
in qemu, mainly pluging the memory region with KVM_MEM_READONLY flag
to kvm
