This chunk is rejected when applied to linux-3.14, because of the reference to SELTEST.
The last three context lines should rather read:
FTR_SECTION_ELSE
b memcpy_power7
ALT_FTR_SECTION_END_IFCLR(CPU_FTR_VMX_COPY)
Same issue with [PATCH 16/33] powerpc: Fix unsafe accesses to parameter area in ELFv2.
