This commit was manufactured to restore the state of the 5.4-RELEASE image.

It only expands to something on i386 and amd64, so the compiled code should be identical. Name of the macro found by: jhb Reviewed by: jhb Backed out previous commit.

This affects db_command.c and kern_shutdown.c. ia64: move all MD prototypes from cpu.h to md_var.h. This affects madt.c, interrupt.c and mp_machdep.c. Remove is_physical_memory(). It's not used (vm_machdep.c). alpha: the MD prototypes have been left in cpu.h with a comment that they should be there. Moving them is left for later. It was expected that the impact would be significant enough to be done in a seperate commit. powerpc: MD prototypes left in cpu.h. Comment added.

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.
