To fix:
In file included from kernel/exit.c:61:
arch/avr32/include/asm/mmu_context.h: In function 'enable_mmu':
arch/avr32/include/asm/mmu_context.h:135: error: implicit declaration of function 'nop'
It needs an include of the new file created in commit ae47394658
("Disintegrate asm/system.h for AVR32"), but since that file only
contains "nop", and since other arch already have precedent of putting
nop in asm/barrier.h we should just delete the new file and put nop in
barrier.h
