函数名称：分配mpi空间

函数原型：MPI mpi_alloc(unsigned nlimbs)

返回类型：MPI

参数：

类型参数名称
unsignednlimbs
34  a等于kmalloc(sizeof * a, GFP_KERNEL)
35  如果非a则返回:a
38  如果nlimbs则
39  array with the limbs 等于mpi_alloc_limb_space(nlimbs)
40  如果非 array with the limbs 则
41  kfree(a)
42  返回:NULL
44  否则
45  array with the limbs = NULL
48  array size (# of allocated limbs) 等于nlimbs
49  number of valid limbs 等于0
50  indicates a negative number 等于0
51  bit 0: array must be allocated in secure memory space 等于0
