[PATCH 10/14] ARM: v6k: select TLS register code according to V6 variants

Russell King - ARM Linux linux at arm.linux.org.uk
Mon Jan 17 14:24:23 EST 2011


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.
