4a565df5ed strategy for block and char devices are rightfully spec_strategy.
I feel like yanking all the "ISODEVMAP" stuff altogether, it looks
like a bad kludge...

911b598f11 1. If some output still present at the end of ttywait, kill it.
2. Even if ttywait() fails, call ttyflush(FREAD) in ttywflush.
This two fixes guarantee that queues are empty after calling ttywflush()
in any case

0217125f2b Carefully choose the value for vm_object_cache_max. The previous calculation
was rather bogus in most cases; the new value works very well for both
large and small memory machines.

25719d742a Remove the evil I perpetrated on this file in the name of the Cyclades driver,
now we're back to the old way.  By way of amends, I cleaned up all the
casting evils and generally neated this file up as much as possible.  It
still, however, needs to die.

95b44faffd Turn on "Capture Effect" avoidence. This modifies the collision algorithm
so that the interface won't have the effect of blocking other senders
during bulk transfers (i.e. hogging the ethernet). It improves performance
in all of my tests by reducing collisions and I believe it to be a Good
Thing.

TS_WOPEN state when CLOCAL is toggled from on to off while there
is no carrier.  There is no way back, and with sio there is no way
forward either (TS_ISOPEN will never be set again for the current
open).  This bug was observed in 1.1 and was fixed in 1.1.5.
