Make calls to ct_user_enter when the kernel is exited
and ct_user_exit when the kernel is entered (in el0_da,
el0_ia, el0_svc, el0_irq and all of the "error" paths).
These macros expand to function calls which will only work
properly if el0_sync and related code has been rearranged
(in a previous patch of this series).
The calls to ct_user_exit are made after hw debugging has been
enabled (enable_dbg_and_irq).
The call to ct_user_enter is made at the beginning of the
kernel_exit macro.
This patch is based on earlier work by Kevin Hilman.
Save/restore optimizations were also done by Kevin.
