Ok. So there's no actual expected use of the remap interface.

Hi,
I'm trying to implement GICv3 (actually GIC-500) in order to support more than
8 cores for ARM64.
Up to 24 cores I didn't notice any significant problems (just slow boot) but
with 64 or 32 cores the Linux kernel is usually got stuck, seldom it completes
the boot.
When examining the
Machines types can have different requirement for default ram
size. Introduce a member in the machine class and set the current
default_ram_size to 128MB.
For QEMUMachine types override the value during the registration of
the machine and for MachineClass introduce the generic class init
setting
Current DEFAULT_RAM_SIZE(128MB) enforced by QEMU would not work for
all machines. Introduce a default_ram_size as part of MachineClass.
The below patches has following behaviour:
1) If the user does not provide -m option, machine's default ram
size will be picked.
2) In case the user
Rename the function so that the reason for its existence is clearer: it
does x86-specific initialization of TCG structures.

We already have pow2floor, mirror it and use instead of a function with
similar results (same in used domain), to clarify our intent.

PXB is a light-weight host bridge whose purpose is to enable
the main host bridge to support multiple PCI root buses.
As oposed to PCI-2-PCI bridge's secondary bus, PXB's bus
is a primary bus and can be associated with a NUMA node

To allow new code to ask the CPU classes for CPU model information and
allow QOM properties to be queried by qmp_device_list_properties(), we
need to be able to safely instantiate a X86CPU object without any
side-effects.
cpu_exec_init() has lots of side-effects on global QEMU state, move it

If multiple root busses are used, root bus 0 cannot use all the

primary busses.

Instead of initializing cpu-as and cpu-thread_id while holding
cpu_list_lock(), initialize it earlier.
This allows the code handling cpu_index and global CPU list to be
isolated from the rest.
