[RESEND][PATCH] x86: Fix warning about cast from pointer to integerof different size

[Alexander Duyck]

This patch fixes a warning reported by the kbuild test robot where we were
casting a pointer to a physical address which represents an integer of a
different size.  Per the suggestion of Peter Anvin I am replacing it and one
other spot where I made a similar cast with an unsigned long.

Resending patch as I realized I forgot to add --auto to stgit command line and
as such the Cc was ignored.  Sorry for the extra noise on the list.
