John Baldwin 0bbc882680 Overhaul the per-CPU support a bit: ... - The MI portions of struct globaldata have been consolidated into a MI struct pcpu. The MD per-CPU data are specified via a macro defined in machine/pcpu.h. A macro was chosen over a struct mdpcpu so that the interface would be cleaner (PCPU_GET(my_md_field) vs. PCPU_GET(md.md_my_md_field)). - All references to globaldata are changed to pcpu instead. In a UP kernel, this data was stored as global variables which is where the original name came from. In an SMP world this data is per-CPU and ideally private to each CPU outside of the context of debuggers. This also included combining machine/globaldata.h and machine/globals.h into machine/pcpu.h. - The pointer to the thread using the FPU on i386 was renamed from npxthread to fpcurthread to be identical with other architectures. - Make the show pcpu ddb command MI with a MD callout to display MD fields. - The globaldata_register() function was renamed to pcpu_init() and now init's MI fields of a struct pcpu in addition to registering it with the internal array and list. - A pcpu_destroy() function was added to remove a struct pcpu from the internal array and list. Tested on: alpha, i386 Reviewed by: peter, jake		2001-12-11 23:33:44 +00:00
