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.
