UML build broken since 3.0.75 (also affects 3.2.x)

UML build broken since 3.0.75 (also affects 3.2.x)

[Antoine Martin]

Linus' vm patches broke the UML build in 3.0.75 onwards:

  CC      mm/memory.o
mm/memory.c: In function ‘vm_iomap_memory’:
mm/memory.c:2363:2: error: implicit declaration of function
‘io_remap_pfn_range’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[1]: *** [mm/memory.o] Error 1
make: *** [mm] Error 2


This fix is just a copy of what is found in later kernels.
Compiled and boot tested both 3.0.80 and 3.2.45, x86_64 and i386.

commit 4d94d6d030adfdea4837694d293ec6918d133ab2
Author: Richard Weinberger <richard@nod.at>
Date:   Tue Feb 7 01:22:47 2012 +0100

    um: Serve io_remap_pfn_range()

    At some places io_remap_pfn_range() is needed.
    UML has to serve it like all other archs do.

If at first you don't succeed, you're doing about average.
