25 * test handling of TF in syscall/sysret: #DB is raised if TF
26 * is 1 at the *end* of syscall/sysret.
28 * This uses 32-bit syscall/sysret because KVM emulates it on Intel processors.
29 * However, the same bug happens with 64-bit syscall/sysret if two vCPUs
30 * "race" to force the emulation of syscall/sysret.
