This commit only added a new occurence of this error :)
It seems that the problem is caused by nommu defintion of pfn_valid() in
microblaze:

define pfn_valid(pfn)       (((pfn) >= min_low_pfn) && \
			       ((pfn) <= (min_low_pfn + max_mapnr)))

but I could not reproduce the error with nommu_defconfig.

I think we can do better than that. The below patch is build-tested
only.

Subject: [PATCH] microblaze: cleanup memory start aliases

There are several variables that have the same meaning and value, but they
are used with different configuration options:

- memory_start - "main memory where the kernel is"
- __page_offset - an alias for memory_start disguised as PAGE_OFFSET fot
  no-MMU case
- min_low_pfn - a legacy from i386 memory layout weirdness, an alias for
  (memory_start >> PAGE_SHIFT)

Since there are "different" variables that point to the start of the
memory, MMU and no-MMU variants of pfn_valid() and ARCH_PFN_OFFSET used
memory_start and __page_offset with min_low_pfn respectively.

Use memory_start for both MMU and no-MMU versions of pfn_valid() and
ARCH_PFN_OFFSET and get rid of __page_offset entirely.

Looks like we have precedence for min_low_pfn failures and we can't blame 
this poor commit :)

I wonder why we don't simply do EXPORT_SYMBOL() in mm/memblock.c, 
non-microblaze architectures do this themselves because it doesn't get 
generically exported:

arch/ia64/kernel/ia64_ksyms.c:EXPORT_SYMBOL(min_low_pfn);       /* defined by bootmem.c, but not exported by generic code */
arch/sh/kernel/sh_ksyms_32.c:EXPORT_SYMBOL(min_low_pfn);

Adding Mike Rapoport.
