linux-next: build failure after merge of the tip tree

[Stephen Rothwell]

Hi all,

After merging the tip tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/video/fbdev/aty/atyfb_base.c: In function 'atyfb_setup_generic':
drivers/video/fbdev/aty/atyfb_base.c:3447:2: error: implicit declaration of function 'ioremap_uc' [-Werror=implicit-function-declaration]
  par->ati_regbase = ioremap_uc(info->fix.mmio_start, 0x1000);
  ^
drivers/video/fbdev/aty/atyfb_base.c:3447:19: warning: assignment makes pointer from integer without a cast
  par->ati_regbase = ioremap_uc(info->fix.mmio_start, 0x1000);
                   ^

Caused by commits

  3cc2dac5be3f ("drivers/video/fbdev/atyfb: Replace MTRR UC hole with strong UC")
  8c7ea50c010b ("x86/mm, asm-generic: Add IOMMU ioremap_uc() variant default")

The latter defines ioremap_uc() for x86 and those architectures that
use asm-generic/io.h - which is not all of them :-( .  The former commit
then uses ioremap_uc().

I have reverted commit 3cc2dac5be3f (and 7d89a3cb159a that follows it)
for today.

This should be fixed by:

http://git.kernel.org/tip/8c7ea50c010b2f1e006ad37c43f98202a31de2cb

The way it was defined was to return NULL if an arch does not have it,
*but* if the asm-generic io.h header is not included on some archs it will still
fail, which leaves us no option but to then poke and define its implementaiton
for archs which opt-out of asm-generic io.h

Benh, in this case I believe its OK to to just map it to ioremap(), let me know
what you think.

I checked and there are other architectures that do not include asm-generic/io.h,
so here is the full patch fix, which I'll post next.

From: "Luis R. Rodriguez" <mcgrof@suse.com>
Subject: [PATCH] arch/*/io.h: Add ioremap_uc() to all architectures

This adds ioremap_uc() only for architectures that do not
include asm-generic.h/io.h as that already provides a default
definition for them for both cases where you have CONFIG_MMU
and you do not, and because of this, the number of architectures
this patch address is less than the architectures that the
ioremap_wt() patch addressed, "arch/*/io.h: Add ioremap_wt() to all
architectures").

In order to reduce the number of architectures we have to
modify by adding new architecture IO APIs we'll have to review
the architectures in this patch, see why they can't add
asm-generic.h/io.h or issues that would be created by doing
so and then spread a consistent inclusion of this header
towards the end of their own header. For instance arch/metag
includes the asm-generic/io.h *before* the ioremap*()
definitions, this should be the other way around but only
once we have guard wrappers for the non-MMU case also for
asm-generic/io.h.
