7 * Note that this file has dual use: when building the kernel
8 * natively, the file is translated into a binary and executed. When
9 * building the kernel in a cross-development environment, this file
10 * gets translated into an assembly file which, in turn, is processed
11 * by awk to generate offsets.h. So if you make any changes to this
12 * file, be sure to verify that the awk procedure still works (see
13 * prin_offsets.awk).
