This patch is update version for [1] as kernel
upgrad to v4.19.
It derives from [2] which has accept by kernel
community after v4.20. Modifacation has been done
to make it be able to enable memory hotplug using
probe method as it originally aims to using acpi.
Also some corresponding configurations in kernel
config are opened.

As memory hotplug for arm64 by acpi is not ready on qemu, we choose
"probe" instead. You can refer to [1] to get more infomation about
"probe". The process of memory hotplug by "probe" in kata lies below:
firstly, add memory in qemu qmp; secondly, echo the start phyical address
of that memory to /sys/devices/system/memory/probe, which will be done
through kata-agent; thirdly, excute online op, then this newly added
memory is capable to be used.
All functions in this patch will be called after "echo" op. It can be
divided into two parts:
1. create page table for that memory;
2. add that memory to memblock.
In this patch, NUMA must be turned off for not all arm64 machine supports
NUMA.
As the newly added memory should be placed from 2T to 6T which is decided
in qemu and phyical address and virtual address will be one-one mapping
when create pgd for that memory, we must config ARM64_VA_BITS as 48.
Also some configs should be turned on, especially "ARCH_MEMORY_PROBE".
We have tested this patch integrated with another patch which performed
that echo op. It works well when using "-m" in command line when start a
kata-container on aarch64 machine.
This patch derived from Maciej Bielski. You can refer to [2] to get full
infomation about it.

The Intel GPU support has been enabled in kata runtime, but the
guest kernel of kata container lacks the support of Intel GPU,
so this commit enables it as default in guest kernel.
CONFIG_DRM, CONFIG_DRM_I915 and CONFIG_DRM_I915_USERPTR are necessary.
Others are obtained by running command "make menuconfig" and selecting
the following options.

Current kata containers can't run with kernel 4.1 built from current x86 config,
it will report error:
```
$ docker run -ti --runtime kata busybox sh
docker: Error response from daemon: oci runtime error: rpc error: code = Internal
desc = Could not run process: container_linux.go:348: starting container process
caused "process_linux.go:402: container init caused \"open /dev/ptmx: no such
file or directory\"".
```
This is caused by bogus devpts mount options. When run container with docker,
docker will assign a default devpts mount for every container which equals to
command below:
```
$ mount -t devpts -o nosuid,noexec,newinstance,ptmxmode=0666,mode=0620,gid=5 \
devpts /dev/pts
```
This requires kernel config `CONFIG_DEVPTS_MULTIPLE_INSTANCES=y` to work properly
under kernel-4.1, but this option is already removed from latest kernel.
It's better to add it back for support older kernel than current 4.14.
