The new PowerPC VMX fast path (__copy_tofrom_user_power7_vmx) is not
exercised by existing copyloops selftests. This patch updates
the selftest to exercise the VMX variant, ensuring the VMX copy path
is validated.
Changes include:
- COPY_LOOP=test___copy_tofrom_user_power7_vmx with -D VMX_TEST is used
in existing selftest build targets.
- Inclusion of ../utils.c to provide get_auxv_entry() for hardware
feature detection.
- At runtime, the test skips execution if Altivec is not available.
- Copy sizes above VMX_COPY_THRESHOLD are used to ensure the VMX
path is taken.
This enables validation of the VMX fast path without affecting systems
that do not support Altivec.
