Hi All,

The kernel exception handling code for 32 bit (transfer_to_handler in 
entry_32.S) clear DBSR and load DBCR0 with 0 (global_dbcr0 variable, which is 
zero) if user space used debug (DBCR0.IDM set).

But I do not same (clearing DBCR0 and DBSR) in 64bit exception handler. Is this 
an issue or I am missing something?

Thanks
-Bharat
