H A 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，
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

H A Dhighmem.rst54 * kmap_local_page(), kmap_local_folio() - These functions are used to create
78 kmap_local_page(), as well as kmap_local_folio() always returns valid virtual
97 kmap_local_page() or kmap_local_folio().
99 Nesting kmap_local_page() and kmap_atomic() mappings is allowed to a certain
101 because the map implementation is stack based. See kmap_local_page() kdocs
105 * kmap_atomic(). This function has been deprecated; use kmap_local_page().
107 NOTE: Conversions to kmap_local_page() must take care to follow the mapping
108 restrictions imposed on kmap_local_page(). Furthermore, the code between
112 both must be made in conjunction with the use of kmap_local_page().
127 users should prefer kmap_local_page() instead of kmap_atomic().
