Since the ENTRY/END macros now have .cfi_startproc/.cfi_endproc, most of the custom arm assembly has no unwind information. Adding the proper cfi directives for these and removing the arm directives. Update the gensyscalls.py script to add these cfi directives for the generated assembly. Also fix the references to non-uapi headers to the proper uapi header. In addition, remove the kill.S, tkill.S, tgkill.S for arm since they are not needed at all. The unwinder (libunwind) is able to properly unwind using the normal abort. After this change, I can unwind through the system calls again. Bug: 11559337 Bug: 11825869 Bug: 11321283 Change-Id: I18b48089ef2d000a67913ce6febc6544bbe934a3
