To: Geert Uytterhoeven, Andrew Morton; +Cc: linux-arch, linux-mm, linux-kernel
The commit 2ae416b142b6 ("mm: new mm hook framework") introduced an empty
header file (mm-arch-hooks.h) for every architecture, even those which
doesn't need to define mm hooks.
As suggested by Geert Uytterhoeven, this could be cleaned through the use
of a generic header file included via each per architecture
asm/include/Kbuild file.
The powerpc architecture is not impacted here since this architecture has
to defined the arch_remap MM hook.

linux-kernel
The commit 2ae416b142b6 ("mm: new mm hook framework") introduced an empty
header file (mm-arch-hooks.h) for every architecture, even those which
doesn't need to define mm hooks.
As suggested by Geert Uytterhoeven, this could be cleaned through the use
of a generic header file included via each per architecture
asm/include/Kbuild file.
The PowerPC architecture is not impacted here since this architecture has
to defined the arch_remap MM hook.
Changes in V2:
--------------
- Vineet Gupta reported that the Kbuild files should be kept sorted.
- Add fix for the newly introduced H8/300 architecture.

So the way this works is that if an arch wants to override a hook, it
will remove the "generic-y += mm-arch-hooks.h" and add
arch/XXX/include/asm/mm-arch-hooks.h, yes?
And the new arch/XXX/include/asm/mm-arch-hooks.h only needs to define
the hook(s) which the arch wants to override?
So nothing will ever be added to include/asm-generic/mm-arch-hooks.h?
Seems fair enough.
Oleg is angling to remove arch_remap(), so there won't be anything left
in these files! But there are plenty of ad-hoc things which *should*
be moved over.

Yes, we do this to avoid patch collisions. Everyone always adds stuff
to the end of the list (Makefiles, #includes, etc etc), thus carefully
maximizing the number of patch collisions :(

Yes that's the way it should work.

This file is the fallback one when no hooks is defined. It is here for
the compiler happiness, and should be kept empty.

I'll try to move some hooks there as soon as I've so free time.
