There shouldn't be any changes for us w.r.t. data integrity and the
recent uncovered dnode dirtiness, as we backported those patches
already.

since e2d55709398e ("vfio: Fold vfio_virqfd.ko into vfio.ko") this
config isn't a tristate anymore but a bool, so adapt to that.
Luckily the kconfig script did the right thing and set (or at least
kept) this to yes anyway

the signed template together with the binary package(s) containing the unsigned
files form the input to our secure boot signing service.
the signed template consists of
- files.json (specifying which files are signed how and by which key)
- packaging template used to build the signed package(s)
the signing service
- extracts and checks the signed-template binary package
- extracts the unsigned package(s)
- signs the needed files
- packs up the signatures + the template contained in the signed-template
package into the signed source package
the signed source package can then be built in the regular fashion (in case of
the kernel packages, it will copy the kernel image, modules and some helper
files from the unsigned package, attach the signature created by the signing
service, and re-pack the result as signed-kernel package).

it's really not just ZFS and AMDGPU modules, but way more and
generating scary looking messages for these "issues" is just noise
that drown real issues. Disable this for now, maybe in another few
years.

makes it easier to cherry-pick newer stable release tags, that
sometimes contain new config values one must pick from.

it's mostly noise for users, and quiet some interpret this as real
problem and report it to us.
Ideally we'd either educate them, or take time ourself, to report this
upstream and see if the situation can be improved overall, but
currently that's not feasible. We should check this out a few releases
down, if the lower hanging fruits got fixed and noise got lower we
could enable it again to catch the more rare cases.

We have a slightly better fix where only a few targeted ZFS module
parts are added to the UBSAN ignore-list, so the rest of the kernel
still gets exposure.

This is generating far too much noise in the logs, so keep it at once
per boot until we (and other user space tools) adapted to the kernel
wanting user space to chose memfd execution behavior very explicitly.

This improves compatibility for guests w.r.t. live-migration, or live
snapshot rollback, to hosts with less (FPU) xfeatures supported, as
long as the set of features that was actually exposed to the guest is
still supported.
This improves on the ad856280ddea ("x86/kvm/fpu: Limit guest
user_xfeatures to supported bits of XCR0") bug fix.

this exposes the FLUSHBYASID CPU flag to nested VMs when running on an
AMD CPU. also reverts a made up check that would advertise
FLUSHBYASID as not supported. this enable certain modern hypervisors
such as VMWare ESXi 7 and Workstation 17 to run nested VMs properly
again.
