Message-ID: <384EDFC5.FFAE939A@ti.com> (raw)
I have been working through the initialization code for the MIPS/Linux
kernel and have traced through to the point
where the MIPS exceptions are installed. I have not been able to locate
the following routines
handle_adel
handle_ades
handle_sys
handle_bp
handle_n
handle_cpu
handle_ov
handle_tr
handle_fpe
I see where these are defined by "extern asmlinkage" references but
can't locate the actual implementation of these
exceptions. Any idea what files these routines might be located in?
Any help would be greatly appreciated
Thank you,
Jeff Harrell
