[PATCH v2] avr32: fix nop compile fails from system.h split up

From: Paul Gortmaker
Date: Tue Apr 03 2012 - 19:14:24 EST


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 ae473946586680b01c13975a3b674de23ad7c93e

"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

[v2: adopt dh's suggestion and assume new special_insns.h needs rm'ing]
