/*
 * To maintain compatibility with current implementations the sigcontext is
 * extended by appending a pointer (v_regs) to a quadword type (elf_vrreg_t)
 * followed by an unstructured (vmx_reserve) field of 101 doublewords. This
 * allows the array of vector registers to be quadword aligned independent of
 * the alignment of the containing sigcontext or ucontext. It is the
 * responsibility of the code setting the sigcontext to set this pointer to
 * either NULL (if this processor does not support the VMX feature) or the
 * address of the first quadword within the allocated (vmx_reserve) area.
 *
 * The pointer (v_regs) of vector type (elf_vrreg_t) is type compatible with
 * an array of 34 quadword entries (elf_vrregset_t).  The entries with
 * indexes 0-31 contain the corresponding vector registers.  The entry with
 * index 32 contains the vscr as the last word (offset 12) within the
 * quadword.  This allows the vscr to be stored as either a quadword (since
 * it must be copied via a vector register to/from storage) or as a word.
 * The entry with index 33 contains the vrsave as the first word (offset 0)
 * within the quadword.
 *
 * Part of the VSX data is stored here also by extending vmx_restore
 * by an additional 32 double words.  Architecturally the layout of
 * the VSR registers and how they overlap on top of the legacy FPR and
 * VR registers is shown below:
 *
 *                    VSR doubleword 0               VSR doubleword 1
