[PATCH] Make x86 latest boot with non-discontig boxes

[Glauber Costa <gcosta@redhat.com>]

Commit 0596152388e234efebce464355186ad9e16c8cb6
broke my box, since it removes completely the call to
memory_present() at e820 setup.

It seems to be really not needed with discontig memory,
but with flat and sparse, I get an early crash. The proposed patch
moves the call memory_present() to setup_memory, the one
present in setup_32.c.
