[Qemu-devel] [PATCH 00/19] Split cpu_exec_init() into an init and a realize part

[Laurent Vivier]

Since commit 42ecaba ("target-i386: Call cpu_exec_init() on realize"),
, commit 6dd0f83 ("target-ppc: Move cpu_exec_init() call to realize function"),
and commit c6644fc ("s390x/cpu: Get rid of side effects when creating a vcpu"),
cpu_exec_init() has been moved to realize function for some architectures
to implement CPU htoplug. This allows any failures from cpu_exec_init() to be
handled appropriately.

This series tries to do the same work for all the other CPUs.

But as the ARM Virtual Machine ("virt") needs the "memory" property of the CPU
in the machine init function (the "memory" property is created in
cpu_exec_init() we want to move to the realize part), split cpu_exec_init() in
two parts: a realize part (cpu_exec_realize(), adding the CPU in the
environment) and an init part (cpu_exec_init(), initializing the CPU, like
adding the "memory" property).

For target-i386, target-s390 and target-ppc, we move back the cpu_exec_init()
into the init part, and put the cpu_exec_realize() into the realize part.
For all the other CPUs, we add the cpu_exec_realize() function into the
realize part.

This also allows to remove all the "cannot_destroy_with_object_finalize_yet"
properties from the CPU device class.
