Subject: IXP4xx: Indirect PCI MMIO compile failure

Hi,

Guess nobody uses indirect PCI MMIO on IXP4xx - since 2.6.29:
arch/arm/mach-ixp4xx/include/mach/io.h:70: error: 'VMALLOC_START' undeclared

(and so on)

That's a part of commit 4b78a9ffabbb03af4032ff704689912298e19070, dated
2008-11-29. Perhaps we should get rid of this hack (indirect MMIO) if
nobody uses it? 64 MB of MMIO PCI space should be more than enough for
everyone :-)

Since VMALLOC_START wants high_memory, I guess the correct patch is
(attached) and that's what I'm going to use if nobody comes with a
better idea.
