lib: Redirect illegal instruction trap to S-mode when not handled

2018-12-31T03:58:26Z

Currently, we fail with error SBI_ENOTSUPP when we are not able to handle illegal instruction trap. Instead, we should just redirect illegal instruction trap to S-mode when not handled. This redirection of illegal instruction trap will help lazy save/restore of floating point registers to work correctly in Linux kernel. Signed-off-by: Anup Patel
