/* For 64-bit kernels with Altivec support, a machine context is exactly
* a sigcontext. For older kernel (without Altivec) the sigcontext matches
* the mcontext upto but not including the v_regs field. For kernels that
* don't AT_HWCAP or return AT_HWCAP without PPC_FEATURE_HAS_ALTIVEC the
* v_regs field may not exit and should not be referenced. The v_regd field
* don't set AT_HWCAP or return AT_HWCAP without PPC_FEATURE_HAS_ALTIVEC the
* v_regs field may not exist and should not be referenced. The v_regd field
* can be refernced safely only after verifying that PPC_FEATURE_HAS_ALTIVEC
* is set in AT_HWCAP. */
