i860mach3.h

这个是LINUX下的GDB调度工具的源码

/* This is an ugly way to hack around the incorrect
 * definition of UPAGES in i386/machparam.h.
 *
 * The definition should specify the size reserved
 * for "struct user" in core files in PAGES,
 * but instead it gives it in 512-byte core-clicks
 * for i386 and i860. UPAGES is used only in trad-core.c.
