[PATCH 0/4] target/s390x/cpu: Restrict CPUS390XState declaration to 'cpu.h'

[Philippe Mathieu-Daudé]

In order to restrict CPUS390XState declaration to "cpu.h" (both
target-specific):
- have the following prototypes take a S390CPU* instead:
  . css_do_sic()
  . sclp_service_call()
  . sclp_service_call_protected()
- restrict cpu_get_tb_cpu_state() definition to TCG

[PATCH 1/4] hw/s390x/css: Have css_do_sic() take S390CPU instead of CPUS390XState

[Philippe Mathieu-Daudé]

"hw/s390x/css.h" is a header used by target-agnostic objects
(such hw/s390x/virtio-ccw-gpu.c), thus can not use target-specific
types, such CPUS390XState.

Have css_do_sic() take S390CPU a pointer, which is target-agnostic.

[PATCH 2/4] hw/s390x/sclp: Have sclp_service_call[_protected]() take S390CPU*

[Philippe Mathieu-Daudé]

"hw/s390x/sclp.h" is a header used by target-agnostic objects
(such hw/char/sclpconsole[-lm].c), thus can not use target-specific
types, such CPUS390XState.

Have sclp_service_call[_protected]() take a S390CPU pointer, which
is target-agnostic.

[PATCH 3/4] target/s390x/cpu: Restrict cpu_get_tb_cpu_state() definition to TCG

[Philippe Mathieu-Daudé]

cpu_get_tb_cpu_state() is TCG specific. Another accelerator
calling it would be a bug, so restrict the definition to TCG,
along with "tcg_s390x.h" header inclusion.

[PATCH 4/4] target/s390x/cpu: Restrict CPUS390XState declaration to 'cpu.h'

"target/s390x/cpu-qom.h" has to be target-agnostic. However, it
currently declares CPUS390XState, which is target-specific.
Move that declaration to "cpu.h".

Patches look reasonable. Thanks, queued them now!
