This test is only covering various edge cases of the
KVM_SET_NESTED_STATE ioctl. Running the VM does not really
add anything.

new_entry is reassigned a new value next line. So
it's redundant and remove it.

This is probably overdue---KVM x86 has quite a few contributors that
usually review each other's patches, which is really helpful to me.
Formalize this by listing them as reviewers. I am including people
with various expertise:
- Joerg for SVM (with designated reviewers, it makes more sense to have
him in the main KVM/x86 stanza)
- Sean for MMU and VMX
- Jim for VMX
- Vitaly for Hyper-V and possibly SVM
- Wanpeng for LAPIC and paravirtualization.
Please ack if you are okay with this arrangement, otherwise speak up.
In other news, Radim is going to leave Red Hat soon. However, he has
not been very much involved in upstream KVM development for some time,
and in the immediate future he is still going to help maintain kvm/queue
while I am on vacation. Since not much is going to change, I will let
him decide whether he wants to keep the maintainer role after he leaves.

KVM/s390 does not have a list of its own, and linux-s390 is in the
loop anyway thanks to the generic arch/s390 match. So use the generic
KVM list for s390 patches.

recalculate_apic_map does not santize ldr and it's possible that
multiple bits are set. In that case, a previous valid entry
can potentially be overwritten by an invalid one.
This condition is hit when booting a 32 bit, >8 CPU, RHEL6 guest and then
triggering a crash to boot a kdump kernel. This is the sequence of
events:
1. Linux boots in bigsmp mode and enables PhysFlat, however, it still
writes to the LDR which probably will never be used.
2. However, when booting into kdump, the stale LDR values remain as
they are not cleared by the guest and there isn't a apic reset.
3. kdump boots with 1 cpu, and uses Logical Destination Mode but the
logical map has been overwritten and points to an inactive vcpu.
