memblock_end_of_DRAM() returns end_address + 1, not end address.
While some code assumes that it returns end address.

Shouldn't we instead fix it the other way around ? IE, make
memblock_end_of_DRAM() does what the name implies, which is to return
the last byte of DRAM, and fix the -other- callers not to make bad
assumptions ?

That was my impression too when I saw this patch.
