Comment # 15 on bug 1189965 from Michal Kube������ek

Looking at mainline commit d5ebde1e2b46 ("hyperv: simplify and rename
generate_guest_id") (to appear in 6.1-rc1), it seems that

- Microsoft does not seem to have any plans to formalize the vendor fields
  in guest os id
- we only set d1 on x86_64 and leave it zero on arm64 without anyone
  noticing or complaining
- d2 was always zero anywhere and we never attempted to set it to anything
  meaningful

Therefore I believe it's time to revisit the question if our patch
patches.suse/suse-hv-guest-os-id.patch is still useful and worth dragging
and refreshing.

My suggestion would be to keep it in SLE15 (all current and future service
packs) for backward compatibility but to drop it in master (i.e. Tubmleweed
in near future) and also in ALP.

Any objections or other ideas?
