That patch did not fix my issue. My problem turned out to be due to TLS
accesses to cp15 not being allowed by qemu in user mode, even though these
are permitted in ARMv6 and above architectures (e.g. see
http://infocenter.arm.com/help/topic/com.arm.doc.ddi0388f/CIHFGFGE.html).
This was corrected by patch: http://patchwork.ozlabs.org/patch/43797/ which
seems to be applied in trunk and will be released in 0.13.0
Thanks.
