[PATCH] ARM: SMP build fix for entry-macro-multi.S

[PATCH] ARM: SMP build fix for entry-macro-multi.S

[Magnus Damm]

From: Magnus Damm <damm@opensource.se>

The assembly code in entry-macro-multi.S does not build without
the include asm/assembler.h in the case of CONFIG_SMP=y.

Fixes the rather theoretical SMP build of mach-shmobile/entry-intc.c:

arch/arm/include/asm/entry-macro-multi.S: Assembler messages:
arch/arm/include/asm/entry-macro-multi.S:20: Error: bad instruction `alt_smp(test_for_ipi r0,r6,r5,lr)'
arch/arm/include/asm/entry-macro-multi.S:20: Error: bad instruction `alt_up_b(9997f)'
make[1]: *** [arch/arm/mach-shmobile/entry-intc.o] Error 1
make: *** [arch/arm/mach-shmobile] Error 2
make: *** Waiting for unfinished jobs....

 This could also be fixed by adding the following line to entry-intc.c:
 #include <asm/assembler.h>
 But that would require all users of entry-macro-multi to do the same.
