This solved the MIPS and IA64 build problems, but there's still one bug left: UML 
does not build:

 /home/mingo/tip/mm/gup.c: In function âcheck_vma_flagsâ:
 /home/mingo/tip/mm/gup.c:456:2: error: implicit declaration of function âarch_vma_access_permittedâ [-Werror=implicit-function-declaration]
   if (!arch_vma_access_permitted(vma, write, false, foreign))
 [...]

Please send a delta patch for this too.

Thanks,
