Enable commonly used DRM/FB drivers for VMs. We may need to enable more
DRM drivers later but for now, just enabled these VM drivers.
Also update changelog. Latest OC public iso is already using OC 5.4
kernel as default kernel.

included by perf.
Keep the python2, python-perf name and libraries location
for backward compatibility.

Tmanager generates tag to build kernel when branch specified.
The tag starts with x86, which leads to the build process failing
to parse the tag.
Modify the generate-rpms.sh to support building with "x86-*" tags.

Hyperv is a native hypervisor that can create virtual machine on x86-64
platform. Enable all hyperv configurations for linux, then it can run
on windows hyperv.

ZRAM is a memory compression method that used for anon swap out/in,
it could help system reclaim more free memory when the applications
have consumed too much memory. So we introduce the ZRAM by kernel
modules, user could insmod it as needed.

BPF CO-RE applications like libbpf are need kernel
headers with all types, so it require BTF type
information built-in.
CONFIG_DEBUG_INFO_BTF have already enabled in x86_64,

Httpchaos need both CONFIG_NETFILTER_XT_MATCH_SOCKET and
CONFIG_NETFILTER_XT_TARGET_TPROXY, these config were aleady opened in x86, but
not on arm64, so just open it.
generate-rpms.sh add parse parameters 'k' for build config of type.
usage: generate-rpms.sh -k config_type
config type is 'kasan' or 'nosign'.

csig need enable support for block device writeback throttling,
so open CONFIG_BLK_WBT and CONFIG_BLK_WBT_MQ.
To sync the config to the same with x86's config, we open:
CONFIG_RT_GROUP_SCHED, CONFIG_SLUB_MEMCG_SYSFS_ON, CONFIG_BLK_CGROUP_IOLATENCY,
CONFIG_BLK_RQ_ALLOC_TIME, CONFIG_BLK_CGROUP_IOCOST, CONFIG_NET_CLS_CGROUP;
To sync the config to the same with x86's config, we close:
CONFIG_NUMA_BALANCING_DEFAULT_ENABLED, CONFIG_SLAB_MERGE_DEFAULT,
CONFIG_CMDLINE_PARTITION

SLI is used for cgroup performance monitoring, but it is not
necessary for some cases(such as running the linux without
cgroups on the embedded device). Therefor we add this
configuration to decide whether package SLI into kernel or not.

centos aarch64 has enabled these configs , and tencent os x86_64 has also enabled these configs.
This option enables a transparent branch optimization that
makes certain almost-always-true or almost-always-false branch
conditions even cheaper to execute within the kernel.
The number of nodes will exceed 16(2^4) for arm64 server(such as
phytium cpu), so we should change the max number of nodes to adapt
these equipment. There is something wrong with IOMMU compatibility
of phytium CPU, so we have to set IOMMU as default passthrough mode
to avoid this isssue. And we can change the IOMMU mode by cmdline
on other arm64 hardware.
