Hi All,

Here is v4 of my patch to address the E820 reservations vs PCI host bridge
ranges issue which are causing touchpad and/or thunderbolt issues on many
different laptop models.

I believe that this is ready for merging now.

Bjorn, can you review/ack this please ?

x86/tip folks it would be ideal if you can pick this up and send it out
as a fix to Linus for 5.15. This fixes a bug which has been plaguing a
lot of users (see all the bug links in the commit msg).

Regards,

Hans

FWIW, I think there's a v5 coming.
