[PATCH 1/1 (resend)] mthca: Modify to support embedded PowerPC platforms

["J.L. Burr" <jlburr-vna1KIf7WgpBDgjK7y7TUQ@public.gmane.org>]

Resending to fix mangling of patch.
---
Here's the patch described in part 0.

Use phys_addr_t, rather than unsigned long, for physical addresses to
accommodate embedded PowerPC processors which use a 36-bit physical address
on a 32-bit CPU.  phys_addr_t will be 64-bits on these platforms.

This patch is for Linux kernel 2.6.26.
