I had moved it to mm/vmalloc.c in response to previous review comments
(namely, its not Xen specific, so it shouldn't live in the Xen part of
the tree).

Then the call will have to be CONFIG_X86. I hadn't realised powerpc were
also using lock_vm_area. However I suspect that the x86 issue that those
functions were written doesn't even exist on powerpc, or any other non-x86
architecture.

Hmmm... Actually looks like a bunch of architectures do lazy sync of the
vmalloc area, although neither ia64 nor powerpc does so. However, all
current users of the alloc_vm_area() function would be okay since none of
the other lazy-syncing architectures are supported by Xen.
