is more than one year old, which I wouldn't care about, if it didn't
introduce a regression on my mackerel
(arch/arm/mach-shmobile/board-mackerel.c) board. With it in place printing
a lot of text over ssh pauses the output multiple times for several
seconds. With this patch reverted the behaviour is back to normal. To
reproduce one can either cat a few largish files under /etc or just dmesg
- if there have been enough messages accumulated.

Thanks
