[PATCH] lmb: Remove __init from lmb_end_of_DRAM()

[Benjamin Herrenschmidt]

We call lmb_end_of_DRAM() to test whether a DMA mask
is ok on a machine without IOMMU, but this function is
marked as __init.

I don't think there's a clean way to get the top of RAM
max_pfn doesn't appear to include highmem or I missed
(or we have a bug :-) so for now, let's just avoid having
a broken 2.6.31 by making this function non-__init and we
can revisit later.

David, you use lmb too, any objection there ?
