[Qemu-devel] [PATCH v8 2/3] libqos: define SPAPR libqos functions

[Laurent Vivier <lvivier@redhat.com>]

Define spapr_alloc_init()/spapr_alloc_init_flags()/spapr_alloc_uninit()

  to allocate and use SPAPR guest memory

Define qtest_spapr_vboot()/qtest_spapr_boot()/qtest_spapr_shutdown()

  to start SPAPR guest with QOSState initialized for it (memory management)

Move qtest_irq_intercept_in() from generic part to PC part.

v7:
- Add David's Rb

v6:
- rebase
- remove added include in tests/libqos/libqos.h
- add Greg's Rb
 
v5:
- replace "ppc64" by "spapr"
- Add test_spapr_vboot()/qtest_spapr_boot()/qtest_spapr_shutdown()
  and remove machine_alloc_XXX() fuctions
