we add the rough kernel config v4.19.23 for arm64, here we let
'make oldconfig'(setting default) to do the transformation from
v4.14.X to v4.19.X.

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.

Remove configs s390_kata_kvm_4.14.x
The patch 0003-serial-forbid-8250-on-s390 is no longer necessary as it
has been upstreamed since version 4.16
The kernel configs have been generated as described in https://github.com/kata-containers/packaging/issues/246
plus the vsock options have been manually enabled:
CONFIG_VSOCKETS=y
CONFIG_VIRTIO_VSOCKETS=y
CONFIG_VIRTIO_VSOCKETS_COMMON=y
