No change to the grub default setting
The kernel rpm installation on rehl/centos is using grubby to setup the
default kernel entry, so we should not change the grub default set from
saved to 0.

Add host environment setup scripts
Testing KVM4NFV project requires special host environment to get the
best result.
Two scrripts are used to setup the environment. The host-setup0.sh setup
the environment that should take effect before the kernel is bringup,
mostly the grub entries. The host-setup1.sh setup the environment that
takes effect after the kernel is up, like some sysfs entry, interrupt
affinity etc. The host-config provides the configurations.

kvmclock: add a new function to update env->tsc.
(Back port from upstream, commit id:
0fd7e098db30e302d27920487f0afec)
The commit
317b0a6d8 fixed an issue which caused by the outdated
env->tsc value, but the fix lead to 'cpu_synchronize_all_states()'
called twice during live migration. The 'cpu_synchronize_all_states()'
takes about 130us for a VM which has 4 vcpus, it's a bit expensive.
Synchronize the whole CPU context just for updating env->tsc is too
wasting, this patch use a new function to update the env->tsc.
Comparing to 'cpu_synchronize_all_states()', it only takes about 20us.

Merge "Make vfio MSI interrupt be non-threaded."
Yunhong Jiang [Tue, 18 Aug 2015 18:27:04 +0000 (11:27 -0700)]
Make vfio MSI interrupt be non-threaded.
Currently the vfio msi interrupt is kept as IRQ thread, this is not good
for NFV scenerio because in NFV scenerio, we want to inject the interrupt
to the guest asap. A threaded IRQ introduces schedule latency.
However, this change is like a quick and dirty and may bring
potential deadlock, because the spinlock_irqsave() from eventfd_signal()
is preemptible in RT kernel, which should not be held on IRQ context. But
changing it to be raw_spinlock is bad because it will increase the latency
a lot if the eventfd is accessed by user space.
The deadlock should be ok since for vfio MSI handler is purely kernel story
and the lock is a per-eventfd lock and seems no one else is using it for the
vfio msi scenario.

Force tick interrupt and get rid of softirq magic
This is a backporting from upstream linux, please refer to
http://marc.info/?t=
142904577100001&r=1&w=2 for more information, the
corresponding kernel commit is
0ff53d09642204c64842 (tick: sched: Force
tick interrupt and get rid of softirq magic).
The purpose of this patch is, if a tick_sched interrupt is missed, don't
try to raise softirq, instead, we can simply trigger the timer interrupt.
The reason is, softirq requires context switch and has much higher overhead
than interrupt.

migration: do cleanup operation after completion
Because of the patch
3ea3b7fa9af067982f34b of kvm, now the migration_end()
is a time consuming operation, which takes about dozens of milliseconds, and
will prolong VM downtime. Such an operation should be done after migration
completion.
For a VM with 8G RAM, this patch can reduce the VM downtime about 32 ms during
