| H A D | highmem.rst | 55 * kmap_local_page()。这个函数是用来要求短期映射的。它可以从任何上下文（包括中断）中调用，
70 kmap_local_page()总是返回一个有效的虚拟地址，并且假定kunmap_local()不会失败。
74 page_address()。然而，使用kmap_local_page() / kunmap_local()总是安全的。
81 kmap()，将页面映射到将被使用的同一线程中，并优先使用kmap_local_page()。
83 嵌套kmap_local_page()和kmap_atomic()映射在一定程度上是允许的（最多到KMAP_TYPE_NR），
85 请参见kmap_local_page() kdocs（包含在 "函数 "部分）。
94 未预期延迟的来源之一。因此用户应该选择kmap_local_page()而不是kmap_atomic()。
111 在64位系统中，调用kmap_local_page()、kmap_atomic()和kmap()没有实际作用，因为64位
