[Xen-devel] ns16550.c's poll_port variable

["Jan Beulich" <JBeulich@xxxxxxxx>]

Hi Keir,

does this really need to be a per-CPU variable? Can't a timer run only
once at a time on the entire system (the more that it gets re-armed only
at the end of the poll function, whereas the variable is consumed at the
start), and hence the variable can be a simple one? Or else, what
subtlety am I overlooking?

Thanks, Jan
