tile: improve illegal translation interrupt handling
First, don't re-enable interrupts blindly in the Linux trap handler. We already handle page faults this way; synchronous interrupts like ILL_TRANS will fire even when interrupts are disabled, and we don't want to re-enable interrupts in that case. For ILL_TRANS, we now pass the ILL_VA_PC reason into the trap handler so we can report it properly; this is the address that caused the illegal translation trap. We print the address as part of the pr_alert() message now if it's coming from the kernel. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
