fix include order in mthca_memfree.c

About commit fdca124a1bcc7e624f6b887c6f26153f40ee43ee ("missing include in mthca"):

- Out of curiousity, what arch and/or config requires <linux/mm.h>? I regularly cross-compile drivers/infiniband for i386, x86_64, ppc64, ia64, sparc64 and ppc, and I haven't needed <linux/mm.h> in mthca_memfree.c.

- When making changes to drivers/infiniband, can you please cc the maintainers or at least a public mailing list? As far as I can tell, the patch went directly to Linus with no public review, which doesn't seem appropriate, no matter how trivial the change.

- When adding includes, please match the existing style and put <linux/xxx.h> includes before any local "yyy.h" includes.

Linus, please apply the patch below to move the include where it belongs.

Thanks,
Roland

alpha, for instance. You are using lowmem_page_address(). That's from linux/mm.h and that's an inline function, so missing include is fatal.

FWIW, the chain of includes that leads to mm.h on i386 is mthca_memfree.h -> linux/pci.h -> asm-i386/pci.h -> linux/mm.h. Other platforms differ...

Sure, no problem.
