Bug description:
After an ADT/DKMS modification (see
https://bugs.launchpad.net/ubuntu/+source/dkms/+bug/1915051) binary
DKMS packages without -dkms in the name started to get tested on ADT
run. This exposed a problem in the Nvidia proprietary DKMS modules for
linux-kvm build:
if we don't have CONFIG_X86_PAT set, the Nvidia drivers (all versions) set
NV_ENABLE_BUILTIN_PAT_SUPPORT to 1 and attempt to build the file
nvidia/nv-pat.c - two functions there make use of __flush_tlb() exported symbol.
But, after kernel v5.8, this symbol is not exported anymore [0][1], not even
flush_tlb_local() is available.
For the time being, we ADT-hinted linux-kvm package, but the driver
requires modifications, in order to fix that.
