commit 61d152dcd195d745a57c73c8f26d99eef255b172
Author: Mark Wielaard <mjw@redhat.com>

    Remove stack-x64x.c specific fallback for _stp_stack_print_fallback().
    
    If the standard kernel based _stp_stack_print_fallback() isn't available
    don't try to be smart and guess at stack addresses ourselves. Just give
    up. Dwarf based unwinding is good enough now and the kernel dump_stack()
    does a much better job than we can at guessing stack values.

commit 7e46daf103bea7dcc92e255629e8412e8f608215

    Remove STP_USE_FRAME_POINTER support and merge i386/x86_64 into stack-x86.c
    
    The only real difference between stack-i386.c and stack-x86_64 was that
    the former supported a buggy frame pointer based unwind. Which we never
    used and for which the kernel has a better fallback (dump_trace).
