Message:

Linux Host and Guest drivers: another attempt to introduce initial support for RHEL 8.5 kernels, bugref:4567.

CentOS kernel 4.18.0-326.el8 (RHEL 8,5) has backported commits from vanilla kernel 5.10+.
Fedora kernel 5.9.0-36.eln104 (RHEL 8,99) does not have some of these changes yet.
This commit attempts to move relevant code into RHEL 8,5 specific section. For some
parts of DRM code, changes are only affect RHEL 8,5 (8,99 is excluded) due to missing
commits (on 8,99) from newer kernels.
