* The purpose of this file is to provide essential/minimal architecture-
9
* specific structure definitions to be included in generic kernel
10
* structures.
11
*
12
* The following rules must be observed:
13
* 1. arch/structs.h shall not depend on kernel.h both directly and
14
* indirectly (i.e. it shall not include any header files that include
15
* kernel.h in their dependency chain).
16
* 2. kernel.h shall imply arch/structs.h via kernel_structs.h , such that
17
* it shall not be necessary to include arch/structs.h explicitly when
18
* kernel.h is included.
