    ARM: 6435/1: Fix HWCAP_TLS flag for ARM11MPCore/Cortex-A9 · c0bb5862
    Tony Lindgren authored
    Commit 14eff181 added proper
    detection for ARM11MPCore/Cortex-A9 instead of detecting them
    as ARMv7. However, it was missing the HWCAP_TLS flags.
    
    HWCAP_TLS is needed if support for earlier ARMv6 is compiled
    into the same kernel. Without HWCAP_TLS flags the userspace
    won't work unless nosmp is specified:
