17 * In a GENERIC kernel, we have lots of these vectors floating about,
18 * all but one of which we want to go away. In a non-GENERIC kernel,
19 * we want only one, ever.
20 *
21 * Accomplish this in the GENERIC kernel by puting all of the vectors
22 * in the .init.data section where they'll go away. We'll copy the
23 * one we want to the real alpha_mv vector in setup_arch.
24 *
25 * Accomplish this in a non-GENERIC kernel by ifdef'ing out all but
26 * one of the vectors, which will not reside in .init.data. We then
27 * alias this one vector to alpha_mv, so no copy is needed.
28 *
29 * Upshot: set __initdata to nothing for non-GENERIC kernels.
30 *
31 * Note we do the same thing for the UNKNOWN kernel, as we need to write
32 * to the machine vector while setting it up.
