Hmm, this breaks the build for me..

arch/i386/kernel/traps.c: In function 'show_trace_log_lvl':
arch/i386/kernel/traps.c:195: error: invalid type argument of '->'
arch/i386/kernel/traps.c:198: error: invalid type argument of '->'
arch/i386/kernel/traps.c:199: error: invalid type argument of '->'
make[1]: *** [arch/i386/kernel/traps.o] Error 1

(The line numbers are different to mainline due to some unrelated
patches, they point to the UNW_PC/UNW_SP usages),


Also, shouldn't this..

	print_symbol("DWARF2 unwinder stuck at %s\n",
		UNW_PC(info.regs));

be using %p ?
