[RFC PATCH 0/8] Remove unneccessary included headers

[RFC PATCH 0/8] Remove unneccessary included headers

[Christophe Leroy]

The purpose of this serie is to limit the number of includes to
only the necessary ones in order to reduce the number of files
recompiled everytime a header file is modified.

This is the start of the work, please provide feedback if any so
that I don't go in the wrong direction.

Christophe Leroy (8):
  powerpc: remove kdump.h from page.h
  powerpc: remove unneeded inclusions of cpu_has_feature.h
  powerpc: remove superflous inclusions of asm-compat.h
  powerpc: remove superflous inclusions of asm/feature-fixups.h
  powerpc: remove superflous inclusions of asm/fixmap.h
  powerpc: declare set_breakpoint() static
  powerpc/book3s: Remove PPC_PIN_SIZE
  powerpc: fix includes in asm/processor.h

Thanks for starting on this.

There's a few build errors, summary below.
