Public bug reported: 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.
