arm64: do not trace atomic operations
Atomic operation function symbols are exported,when CONFIG_ARM64_LSE_ATOMICS is defined. Prefix them with notrace, so that an user can not trace these functions. Tracing these functions causes kernel crash. Signed-off-by: Pratyush Anand <panand@redhat.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
