If CONFIG_CPU_V6 is enabled, we may or may not have the TLS register. Use the conditional code which copes with this variability. Otherwise, if CONFIG_CPU_32v6K is set, we know we have the TLS register on all supported CPUs, so use it unconditionally. Signed-off-by: Russell King <redacted>
Acked-by: Nicolas Pitre <redacted> Note: this is becoming a bit confusing and prone to mistake when we have: CONFIG_CPU_V6 CONFIG_CPU_V6K CONFIG_CPU_32v6 CONFIG_CPU_32v6K I don't know what to suggest for a less similar naming scheme between the CPU design and the allowed instruction set though.
