From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
memblock_alloc_nid() used to fallback to allocating anywhere by using
memblock_alloc() as a fallback.
However, some of my previous patches limit memblock_alloc() to the region
covered by MEMBLOCK_ALLOC_ACCESSIBLE which is not quite what we want
for memblock_alloc_try_nid().
So we fix it by explicitely using MEMBLOCK_ALLOC_ANYWHERE.
Not that so far only sparc uses memblock_alloc_nid() and it hasn't been updated
to clamp the accessible zone yet. Thus the temporary "breakage" should have
no effect.
