{linux,bsd}-user: Introduce get_task_state()

2024-03-06T12:35:19Z

A CPU's TaskState is stored in the CPUState's void *opaque field, accessing which is somewhat awkward due to having to use a cast. Introduce a wrapper and use it everywhere.

ppc: spapr: cleanup cr get/set with helpers.

2023-05-05T15:34:22Z

The bits in cr reg are grouped into eight 4-bit fields represented by env->crf[8] and the related calculations should be abstracted to keep the calling routines simpler to read. This is a step towards cleaning up the related/calling code for better readability.
