31 * followed by an unstructured (vmx_reserve) field of 69 doublewords. This

35 * either NULL (if this processor does not support the VMX feature) or the
36 * address of the first quadword within the allocated (vmx_reserve) area.
37 *
38 * The pointer (v_regs) of vector type (elf_vrreg_t) is type compatible with
39 * an array of 34 quadword entries (elf_vrregset_t). The entries with
40 * indexes 0-31 contain the corresponding vector registers. The entry with
41 * index 32 contains the vscr as the last word (offset 12) within the
42 * quadword. This allows the vscr to be stored as either a quadword (since
43 * it must be copied via a vector register to/from storage) or as a word.
44 * The entry with index 33 contains the vrsave as the first word (offset 0)
45 * within the quadword.
46 *
47 * Part of the VSX data is stored here also by extending vmx_restore
48 * by an additional 32 double words. Architecturally the layout of
49 * the VSR registers and how they overlap on top of the legacy FPR and

13 * Memory barrier.
14 * The sync instruction guarantees that all memory accesses initiated
15 * by this processor have been performed (with respect to all other
16 * mechanisms that access memory). The eieio instruction is a barrier
17 * providing an ordering (separately) for (a) cacheable stores and (b)
18 * loads and stores to non-cacheable memory (e.g. I/O devices).
19 *
20 * mb() prevents loads and stores being reordered across this point.
21 * rmb() prevents loads being reordered across this point.
22 * wmb() prevents stores being reordered across this point.
23 * read_barrier_depends() prevents data-dependent loads being reordered
24 * across this point (nop on PPC).
25 *
26 * *mb() variants without smp_ prefix must order all types of memory
27 * operations with one another. sync is the only instruction sufficient
28 * to do this.
29 *
30 * For the smp_ barriers, ordering is for cacheable memory operations
31 * only. We have to use the sync instruction for smp_mb(), since lwsync
32 * doesn't order loads with respect to previous stores. Lwsync can be
33 * used for smp_rmb() and smp_wmb().
34 *
35 * However, on CPUs that don't support lwsync, lwsync actually maps to a
36 * heavy-weight sync, so smp_wmb() can be a lighter-weight eieio.
