The kernel config was derived from the 4.19.13 kernel config
run through the 'make oldconfig' with all defaults accepted,
except for:
- NET_VENDOR_MICROCHIP (defauly 'y', set to 'n')

We already have 4.9.x, 4.14.x, and 4,19.x as LTS releases.
4.9.x has a longer lifetime as 4.4.x as well and fewer security
fixes can be backported to 4.4.x. Remove it.

packet.net will soon have x86 and arm64 machines with NFPs.
Enable the driver for it.
The 4.9 kernel only has support for the NFP VF driver,
so don't enable it there.

A previosu commit removed suppoer for 4.18.x kernels for
arm64 and s390x but did not remove the config files. Fix it.

The logic for perf became too complex. Just build for latest LTS
and latest stable.
Disable for arm64 for now as it is broken for 4.19 due to a header
mismatch:

The kernel configs were constructed by running the 4.18.x config
through the 4.19 oldconfig process.
The 4.19.x has a new option, RANDOM_TRUST_CPU, which indicates
if the CPUs random instruction is to be trusted. It defaults to
"no" and this default was accepted.
Most of the defaults were accepted, except for:
BLK_CGROUP_IOLATENCY=y
NFT_TUNNEL=y
NFT_OSF=y
NFT_TPROXY=y
NETFILTER_XT_MATCH_SOCKET=y
NET_VENDOR_CADENCE=n
NET_VENDOR_NETERION=n
NET_VENDOR_PACKET_ENGINES=n
We also disallow CIFS for insecure legacy servers:
CIFS_ALLOW_INSECURE_LEGACY=n
For arm64, the following changes were made to the default:
SENSORS_RASPBERRYPI_HWMON=y
CRYPTO_DEV_QCOM_RNG=m
CRYPTO_DEV_HISI_SEC=m
For s390x, the additional changes were made to the default:
KERNEL_BZIP2 (default is gzip)
GCC_PLUGINS=y
GCC_PLUGIN_STRUCTLEAK=y
GCC_PLUGIN_STRUCTLEAK_BYREF_ALL=y
GCC_PLUGIN_RANDSTRUCT=y
GCC_PLUGIN_RANDSTRUCT_PERFORMANCE=y
Running the 4.18 and 4.19 kernel config through
./scripts/kconfig-split.py yields the following 4.19.x
only config options for x86_64:

After 'make oldconfig' we check that that the kernel config
is as we expect and error if they don't. We used to print
the default 'diff' output on a mismatch but a unified diff
is easier to read.
