That's partly why there was a question mark in my unnecessarily snarky
reply. I was only thinking of who should read a manual that might need
a fork truck to lift were it on paper... and then give an answer...
you, me... or...

In any case, I do regret being snarky... and to maybe make up for
it... check out this link... where you'll find all sorts of ARM
manuals.
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.100095_0003_06_en/i
ndex.html

and download the "ARM Cortex-A72 MPCore Processor Technical Reference
Manual" where it will say about 1/3 down page 1-15 that the Cortex-A72
Processor implements the ARM v8-A architecture, which includes...
"Support for all Exception levels, EL0, EL1, EL2, EL3 in each
Execution state."

There are several more manuals, including more for the A72, at this
same link.

I Googled "arm a72 technical reference manual" and it was the first
link shown.
