powerpc/fsl: Fix the flush of branch predictor.
commit 27da80719ef132cf8c80eb406d5aeb37dddf78cc upstream. 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.
