#     powerpc: Force inlining of cpu_has_feature() to avoid build failure
#     
#     The code relies on constant folding of cpu_has_feature() based
#     on possible and always true values as defined per
#     CPU_FTRS_ALWAYS and CPU_FTRS_POSSIBLE.
#     
#     Build failure is encountered with for instance
#     book3e_all_defconfig on kisskb in the AMDGPU driver which uses
#     cpu_has_feature(CPU_FTR_VSX_COMP) to decide whether calling
#     kernel_enable_vsx() or not.
#     
#     The failure is due to cpu_has_feature() not being inlined with
#     that configuration with gcc 4.9.
#     
#     In the same way as commit acdad8fb4a15 ("powerpc: Force inlining of
#     mmu_has_feature to fix build failure"), for inlining of
#     cpu_has_feature().
