We plan to use jump label for cpu_has_feature. In order to implement this we need to include the linux/jump_label_base.h in asm/cputable.h. But it seems that asm/cputable.h is so basic header file for ppc that it is almost included by all the other header files. The including of the linux/jump_label_base.h will introduces various recursive inclusion. And it is very hard to fix that. So we choose to move the function cpu_has_feature to a separate header file before using the jump label for it. No functional change.
