[Qemu-devel] [PULL 2/6] monitor: reuse user_creatable_add_opts() instead of user_creatable_add()

[Eduardo Habkost]

From: Igor Mammedov <imammedo@redhat.com>

Simplify code by dropping ~57LOC by merging user_creatable_add()
into user_creatable_add_opts() and using the later from monitor.
Along with it allocate opts_visitor_new() once in user_creatable_add_opts().

As result we have one less API func and a more readable/simple
user_creatable_add_opts() vs user_creatable_add().

[Qemu-devel] [PULL 3/6] monitor: fix qmp/hmp query-memdev not reporting IDs of memory backends

[Eduardo Habkost]

From: Igor Mammedov <imammedo@redhat.com>

Considering 'id' is mandatory for user_creatable objects/backends
and user_creatable_add_type() always has it as an argument
regardless of where from it is called CLI/monitor or QMP,
Fix issue by adding 'id' property to hostmem backends and
set it in user_creatable_add_type() for every object that
implements 'id' property. Then later at query-memdev time
get 'id' from object directly.

[Qemu-devel] [PULL 5/6] numa: make -numa parser dynamically allocate CPUs masks

[Eduardo Habkost]

From: Igor Mammedov <imammedo@redhat.com>

so it won't impose an additional limits on max_cpus limits
supported by different targets.

It removes global MAX_CPUMASK_BITS constant and need to
bump it up whenever max_cpus is being increased for
a target above MAX_CPUMASK_BITS value.

Use runtime max_cpus value instead to allocate sufficiently
sized node_cpu bitmasks in numa parser.

[Qemu-devel] [PULL 6/6] qmp: Report QOM type name on query-cpu-definitions

[Eduardo Habkost]

The new typename attribute on query-cpu-definitions will be used
to help management software use device-list-properties to check
which properties can be set using -cpu or -global for the CPU
model.
