3.5-rc1 do_mmap implicit-function-declaration error

I applied vbox_kernel3.2.0_patch then hit this error.

How does a 3.2 patch fix a 3.5rc error?

I am not saying it should fix the error, I am just providing information on what I did.
This is an error that cropped up late in 3.4.0-git and in 3.5-rc1 as a result of a change in the kernel.

r41660 contains a changeset which should allow it to compile VirtualBox against Linux 3.5. Apply the same change to the files in /usr/src/vboxhost-*/.
