 Module Name:	src

 Modified Files:
 	src/sys/arch/ia64/ia64: db_trace.c
 	src/sys/arch/ia64/unwind: stackframe.c
 
 Log Message:
 Don't check for unsigned variables being less than 0 in
 patchunwindframe(). Instead, check before subtracting, which in this
 case means at the call site.
 
 It would probably be better to change the call signature so the
 subtraction happens inside patchunwindframe(), but since I don't
 really know exactly what this code is trying to do I'm not comfortable
 changing it.
 
 Issue 1 in PR 51297 from David Binderman.
