Subject: Thumb Issue in ARM

Dear all,


We are facing one issue in user space, if we enable thumb mode and in kernel
whether we enable or disable thumb mode or code run in both scenario.
we could not understand the reason.

Our core is ARM cortex A15,
Kernel 3.8.13

One more issue if we disable THUMB in kernel we got undefined instruction in

Thanks
