#     powerpc/fscr: Enable interrupts earlier before calling get_user()
#     
#     The function get_user() can sleep while trying to fetch instruction
#     from user address space and causes the following warning from the
#     scheduler.
#     
#     BUG: sleeping function called from invalid context
#     
#     Though interrupts get enabled back but it happens bit later after
#     get_user() is called. This change moves enabling these interrupts
#     earlier covering the function get_user(). While at this, lets check
#     for kernel mode and crash as this interrupt should not have been
#     triggered from the kernel context.
