#     powerpc/fsl: Fix the flush of branch predictor.
#     
#     The commit identified below adds MC_BTB_FLUSH macro only when
#     CONFIG_PPC_FSL_BOOK3E is defined. This results in the following error
#     on some configs (seen several times with kisskb randconfig_defconfig)
#     
#     arch/powerpc/kernel/exceptions-64e.S:576: Error: Unrecognized opcode: `mc_btb_flush'
#     make[3]: *** [scripts/Makefile.build:367: arch/powerpc/kernel/exceptions-64e.o] Error 1
#     make[2]: *** [scripts/Makefile.build:492: arch/powerpc/kernel] Error 2
#     make[1]: *** [Makefile:1043: arch/powerpc] Error 2
#     make: *** [Makefile:152: sub-make] Error 2
#     
#     This patch adds a blank definition of MC_BTB_FLUSH for other cases.
#     
#     Fixes: 10c5e83afd4a ("powerpc/fsl: Flush the branch predictor at each kernel entry (64bit)")
