These configs are:
- HYPERVISOR_GUEST
- PCI_XEN
- XEN_ACPI_PROCESSOR
- XEN_DEBUG_FS
- XEN_MCE_LOG
- XEN_PCIDEV_BACKEND
- XEN_PCIDEV_FRONTEND

This patch also replaces config 'XEN_SCRUB_PAGES' with the
'XEN_SCRUB_PAGES_DEFAULT', because it was renamed since 4.19 release.

This BPF_UNPRIV_DEFAULT_OFF option was introduced in v5.13 in
08389d888287 ("bpf: Add kconfig knob for disabling unpriv bpf by
default")
But it was added as one of those somewhat confusing double negative
things, and so the implicit "default n" that Kconfig processing meant
that unpriv eBPF was enabled by default in v5.13 through v5.15.
In v5.16 it was corrected with commit 8a03e56b253e ("bpf: Disallow
unprivileged bpf by default") since there were security concerns
relating to having it enabled.
In that commit we see "Sync with what many distros are currently
applying already, and disable unprivileged BPF by default."
In a generic x86-64 Yocto boot we currently see this in dmesg as:
Spectre V2 : WARNING: Unprivileged eBPF is enabled with eIBRS on,
data leaks possible via Spectre v2 BHB attacks!
I've suggested the stable team do a backport to v5.15, but in any
event, it probably makes sense for us to be explicit on our default.

Since we run under emulation, we need CONFIG_PCI_HOST_GENERIC to get
the right devices enabled.
We include the feature fragment that enables that, only where we need
it. For the moment, -tiny won't support things like graphical boot.

We are working a bit ahead of the aufs project itself, but we can
fix the issues iwth 5.18+ by following the pattern of other

Move the USB and VIRTIO GPU stuff out of gfx, as those should be handled
in the usb and virtio scc files. Add the PCI scc for virtio (which
thinks it's PCI on this QEMU setup), and add a tiny.scc/cfg to get tiny
working.
Also, EARLY_PRINTK does not exist for arm64. So remove those from the
common configs.

https://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git/commit/?h=for-next&id=55de8686df7ed2b5237867b130e30c728bbd9db4
kconfig: change .config format to use =n instead of "is not set"
The .config file uses "# CONFIG_FOO is not set" form to represent
disabled options. In the old days, it was useful because the .config
was directly included from Makefiles. For example, you can use
"ifdef CONFIG_FOO" in Makefiles to check if the option is enabled.
Commit c955ccafc38e ("kconfig: fix .config dependencies") introduced
include/config/auto.conf, which mirrors the .config, but trims down
all disabled options.
Since then, include/config/auto.conf defines CONFIG options during the
build. The .config is used just for storing the user's configuration.
I do not see a strong reason to use a particular pattern of comment
for disabled options.
With this commit, Kconfig will output disable options in a more natural
form, "CONFIG_FOO=n".
Kconfig accepts both "# CONFIG_FOO is not set" and "CONFIG_FOO=n" as a
valid input. You do not need to update arch/*/configs/*_defconfig files
for now. "git bisect" should be able to cross the commit in both ways
without any issue.
A problem may occur if you parse the .config for the "# ... is not set"
patterns.
I adjusted streamline_config.pl, merge_config.sh,
scripts/kconfig/tests/.
