+Subject: [PATCH] Revert "target/ppc: Move SPR_DSISR setting to powerpc_excp"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit 336e91f85332dda0ede4c1d15b87a19a0fb898a2.
+
+It breaks the --disable-tcg build:
+
+ ../target/ppc/excp_helper.c:463:29: error: implicit declaration of
+ function ‘cpu_ldl_code’ [-Werror=implicit-function-declaration]
+
+We should not have TCG code in powerpc_excp because some kvm-only
+routines use it indirectly to dispatch interrupts. See
+kvm_handle_debug, spapr_mce_req_event and
+spapr_do_system_reset_on_cpu.
+
+We can re-introduce the change once we have split the interrupt
+injection code between KVM and TCG.
