Dhighmem.rst55 * 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，
67 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。
69 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），
71 请参见kmap_local_page() kdocs（包含在 "函数 "部分）。
80 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()。
97 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

Dhighmem.rst56 * kmap_local_page(). This function is used to require short term mappings.
76 kmap_local_page() always returns a valid virtual address and it is assumed
83 always safe to use kmap_local_page() / kunmap_local().
95 kmap_local_page().
97 Nesting kmap_local_page() and kmap_atomic() mappings is allowed to a certain

114 users should prefer kmap_local_page() instead of kmap_atomic().
