[PATCH-for-9.1 22/27] target/s390x: Convert to TCGCPUOps::get_cpu_state(


From: Philippe Mathieu-Daudé
Subject: [PATCH-for-9.1 22/27] target/s390x: Convert to TCGCPUOps::get_cpu_state()
Date: Tue, 19 Mar 2024 16:42:51 +0100

Convert cpu_get_tb_cpu_state() to TCGCPUOps::get_cpu_state().

Note, now s390x_get_cpu_state() is restricted to TCG.
