2011-02-02	ARM: v6k: select TLS register code according to V6 variants	Russell King
	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.

2010-07-09	ARM: 6207/1: Replace CONFIG_HAS_TLS_REG with HWCAP_TLS and check for it on V6	Tony Lindgren
	The TLS register is only available on ARM1136 r1p0 and later. Set HWCAP_TLS flags if hardware TLS is available and test for it if CONFIG_CPU_32v6K is not set for V6. Note that we set the TLS instruction in __kuser_get_tls dynamically as suggested by Jamie Lokier <jamie@shareable.org>. Also the __switch_to code is optimized out in most cases as suggested by Nicolas Pitre <nico@fluxnic.net>.
