2798ee63b0 hw/isa/i82378: Propagate error if PC_SPEAKER device creation failed
In commit 40f8214fcd ("hw/audio/pcspk: Inline pcspk_init()")
we neglected to give a change to the caller to handle failed
device creation cleanly. Respect the caller API contract and
propagate the error if creating the PC_SPEAKER device ever
failed. This avoid yet another bad API use to be taken as
example and copy / pasted all over the code base.

9348028e7e target: Move ArchCPUClass definition to 'cpu.h'
The OBJECT_DECLARE_CPU_TYPE() macro forward-declares each
ArchCPUClass type. These forward declarations are sufficient
for code in hw/ to use the QOM definitions. No need to expose
these structure definitions. Keep each local to their target/

... the cpu state is not synchronized when the apic-id is available as

The cpu state should be synchronized when apic-id is available. Otherwise
the "info lapic <apic-id>" always returns stale data.

27a6e78ef0 target/riscv: Move TYPE_RISCV_CPU_BASE definition to 'cpu.h'
TYPE_RISCV_CPU_BASE depends on the TARGET_RISCV32/TARGET_RISCV64
definitions which are target specific. Such target specific
definition taints "cpu-qom.h".

Since "cpu-qom.h" must be target agnostic, remove its target
specific definition uses by moving TYPE_RISCV_CPU_BASE to
"target/riscv/cpu.h".

"target/riscv/cpu-qom.h" is now fully target agnostic.
Add a comment clarifying that in the header.

Our convention is to add such target agnostic QOM declarations in

6ee45fac56 target: Unify QOM style
Enforce the style described by commit 067109a11c ("docs/devel:
mention the spacing requirement for QOM"):

  The first declaration of a storage or class structure should
  always be the parent and leave a visual space between that
  declaration and the new code. It is also useful to separate
  backing for properties (options driven by the user) and internal
  state to make navigation easier.
