[Qemu-devel] [PATCH v2 0/2] memory: extend "info mtree" with flat view dump

[Peter Xu <peterx@redhat.com>]

v2:
- fix a size error in patch 2
- add r-b for Marc-André in patch 1

Each address space has its own flatview. It's another way to observe
memory info besides the default memory region hierachy, for example,
if we want to know which memory region will handle the write to
specific address, a flatview will suite more here than the default
hierachical dump.

I used it to debug a vt-d memory region overlap issue. Do we need
this? I think we can at least consider patch 1, which is a cleanup of
existing codes. :)

Please review. Thanks,

Peter Xu (2):
  memory: provide common macros for mtree_print_mr()
  memory: hmp: dump flat view for 'info mtree'
