With the availability of a fruity range of arm64 systems, it becomes
obvious that QEMU doesn't deal very well with limited IPA ranges when
used as a front-end for KVM.
This short series aims at making usable on such systems:
- the first patch makes the creation of a scratch VM IPA-limit aware
- the second one actually removes the highmem devices from the
computed IPA range when highmem=off
- the last one addresses an imprecision in the documentation for the
highmem option
This has been tested on an M1-based Mac-mini running Linux v5.14-rc6.
