+QEMU SVM VMCB exit_code is uint32_t when AMD spec requires uint64_t
+Description of problem:
+QEMU's SVM implementation incorrectly uses a 32-bit parameter for the exit code in the `cpu_vmexit` function, despite the AMD SVM specification requiring a 64-bit exit code field in the VMCB (Virtual Machine Control Block).
+
+I think the issue is in `target/i386/svm.c` in the `cpu_vmexit` function.
+
+The `exit_code` parameter is declared as `uint32_t` but should be `uint64_t` according to the AMD SVM specification. This causes exit codes to be truncated to 32 bits, resulting in values like 0xffff_ffff instead of the expected 0xffff_ffff_ffff_ffff.
+Steps to reproduce:
