Subject: ARM: Fix !kuser helpers case
From: Russell King <rmk+kernel@xxxxxxxxxxxxxxxx>
commit 1b16c4bcf80e319b2226a886b72b8466179c8e3a upstream.
Fix yet another build failure caused by a weird set of configuration
settings:
LD init/built-in.o
arch/arm/kernel/built-in.o: In function `__dabt_usr':
/home/tom3q/kernel/arch/arm/kernel/entry-armv.S:377: undefined reference to `kuser_cmpxchg64_fixup'
arch/arm/kernel/built-in.o: In function `__irq_usr':
/home/tom3q/kernel/arch/arm/kernel/entry-armv.S:387: undefined reference to `kuser_cmpxchg64_fixup'
caused by:
CONFIG_KUSER_HELPERS=n
CONFIG_CPU_32v6K=n
CONFIG_NEEDS_SYSCALL_FOR_CMPXCHG=n
