[Qemu-devel] [PATCH 0/3] Remove may_overlap from MemoryRegion and use priorities instead

[Alexey Korolev]

At the moment may_overlap flag of MemoryRegion structure is used
inconsistently, and ignored by the address range assignment process.
In fact may_overlap flag can be fully substituted with priority
of the MemoryRegion structure. Also usage of MemoryRegion
priorities is a bit confusing. Exisiting priorities can take values
0,1,2 or even 1000.

This patch removes these drawbacks and introduces a predefined set
of priorities for MemoryRegion.

This code does not affect the exisiting memory topology build process,
so does not cause any issues related to change of regions visibility.

Alexey Korolev (3):
  Replacing memory_region_add_subregion_overlap
  Remove may_overlap flag from MemoryRegion structure
  Docs update: Overlapping memory regions and priority
