Commit 14eff1812679c76564b775aa95cdd378965f6cfb 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: Kernel panic - not syncing: Attempted to kill init!
