Paolo Bonzini 65c9d60a3a target-i386: correctly propagate retaddr into SVM helpers ... Commit 2afbdf8 ("target-i386: exception handling for memory helpers", 2015-09-15) changed tlb_fill's cpu_restore_state+raise_exception_err to raise_exception_err_ra. After this change, the cpu_restore_state and raise_exception_err's cpu_loop_exit are merged into raise_exception_err_ra's cpu_loop_exit_restore. This actually fixed some bugs, but when SVM is enabled there is a second path from raise_exception_err_ra to cpu_loop_exit. This is the VMEXIT path, and now cpu_vmexit is called without a cpu_restore_state before. The fix is to pass the retaddr to cpu_vmexit (via cpu_svm_check_intercept_param). All helpers can now use GETPC() to pass the correct retaddr, too.
