Description
The changes integrated as part of the Intel SpeedStep support included changes (two new
fields) to the processor_info_t structure. Unfortunately, the processor_info_t structure
is a public and stable interface returned by processor_info(2). processor_info(2) accepts,
as an argument, a pointer to a processor_info_t structure and copies the kernel
representation of the structure to the caller. Applications that call processor_info(2)
and are not recompiled with the new processor_info_t definition may have corruption to
their address spaces.
