* remotes/ehabkost/tags/machine-next-pull-request:
MAINTAINERS: Update git URLs for my trees
hw/acpi-build: Fix SRAT memory building in case of node 0 without RAM
NUMA: Replace MAX_NODES with nb_numa_nodes in for loop
numa: cpu: calculate/set default node-ids after all -numa CLI options are parsed
arm: drop intermediate cpu_model -> cpu type parsing and use cpu type directly
pc: use generic cpu_model parsing
vl.c: convert cpu_model to cpu type and set of global properties before machine_init()
cpu: make cpu_generic_init() abort QEMU on error
qom: cpus: split cpu_generic_init() on feature parsing and cpu creation parts
hostmem-file: Add "discard-data" option
osdep: Define QEMU_MADV_REMOVE
vl: Clean up user-creatable objects when exiting
