Are you sure about enabling interrupts before going to "no_context" ? If somebody does a user access "in atomic" with interrupt disabled (with the expectation that a fault would be caught by search_exception_tables and returned as -EFAULT), such code probably doesn't expect interrupts to be re-enabled implicitely.
I hadn't considered that... I'll review this and make sure this isn't what we intended (it probably isn't) and get it fixed. Thanks, Richard Kuo -- Sent by an employee of the Qualcomm Innovation Center, Inc. The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum.
