[Qemu-devel] [PATCH v3 00/10] Refactor cpu topo into machine properties

[Like Xu <like.xu@linux.intel.com>]

This patch series make existing cores/threads/sockets into machine
properties and get rid of global smp_* variables they use currently.

The purpose of getting rid of globals is disentangle layer violations and
let's do it one step at a time by replacing the smp_foo with qdev_get_machine()
as few calls as possible and delay other related refactoring efforts.

==changelog==

v3:

- rephrase commit messages
- s/of/of present/ for CpuTopology comment
- drop reduanct arguments such as cpu_type
- use ms instead of macs in migration context
- rebase to commit 1b46b4daa6

v2: https://patchwork.ozlabs.org/cover/1095727/

- pass MachineState via call chain with trivial fixups
- replace smp_cpus directly at places if it's only used once
- s/topo/smp/ and drop smp_ prefix inside CpuTopology structure
- add more commit messages to explaining what patch does
- fix Patchew build failure for xen usage
- use macs rather than ms in migration context for MigrationState
- cleanup unrelated and redundant changes
- spilt OpenRISC and RISC-V related patches
