In -tip there are many instances where multiple ifdefs are used which
can be easily avoidable to make core more readable and consistent.
Like multiple 'ifdef __KERNEL__' in asm/bitops.h :
diff --git a/arch/x86/include/asm/bitops.h b/arch/x86/include/asm/bitops.h

Similarly in ifdef __KERNEL__ in asm/e820.h and asm/signal.h
And similarly others ifdef block.
