<para revision="239268">ARM support has been greatly improved, including support
for ARMv6 and ARMv7, SMP and thread-local storage (TLS).
Additionally support for some newer SoC like the MV78x60 and OMAP4 was added.

<para revision="254918">Superpages support on ARM has been added. Superpages support
provides improved performance and scalability by allowing TLB
translations to dynamically cover large physical memory regions.
All ARMv6 and ARMv7-based platforms can take advantage of this feature.
