This series introduces stack check instrumentation on Arm. This is
helpful for safety certification efforts. I'm sending this in an RFC
state because I wanted to gather opinions on the approach of using
-finstrument-functions.
Stewart Hildebrand (3):
xen: add no_instrument_function attributes
xen: silence maybe-unitialized warning
xen/arm: stack check instrumentation
