函数名称：FPU state for core dumps.* This is only used for a.out dumps now.* It is declared generically using elf_fpregset_t (which is* struct user_i387_struct) but is in fact only used for 32-bit* dumps, so on 64-bit it is really struct user_i387_ia32_struct.

函数原型：int dump_fpu(struct pt_regs *regs, struct user_i387_struct *ufpu)

返回类型：int

参数：
