Kumar Gala 27e6672bb9 [LMB]: Fix initial lmb add region with a non-zero base 
If we add to an empty lmb region with a non-zero base we will not
coalesce the number of regions down to one.  This causes problems on
ppc32 for the memory region as its assumed to only have one region.

We can fix this be easily specially casing the initial add to just
replace the dummy region.

David S. Miller eea89e13a9 [LMB]: Fix bug in __lmb_alloc_base(). 
We need to check lmb_add_region() for errors, it can run out
of regions etc.

Also, the size needs to be padded to the given alignment
or else the lmb.reserved regions don't get expanded and
instead we get tons of holes and eventually run out of
regions prematurely.
