fix deadlock in the 8139too driver: poll handlers should never forcibly
enable local interrupts, because they might be used by netpoll/printk
from IRQ context.

Currently WAN router drivers can be built in-kernel while the
register/unregister_wan_device interfaces are built as modules.
This causes:
drivers/built-in.o: In function `cycx_init':
cycx_main.c:(.init.text+0x5c4b): undefined reference to `register_wan_device'
drivers/built-in.o: In function `cycx_exit':
cycx_main.c:(.exit.text+0x560): undefined reference to `unregister_wan_device'
make: *** [.tmp_vmlinux1] Error 1
The problem is caused by tristate -> bool conversion (y or m => y),
so convert WAN_ROUTER_DRIVERS to a tristate so that the correct
dependency is preserved.

Fix sizing of big_bytes in the case of vlan frames. The 4
VLAN_HLEN bytes were omitted, leading to sizing the big buffer
4 bytes smaller than it should be. Due to how rx buffers are
carved from pages, this was harmless for the common (9000, 1500)
byte MTUs, but could lead to data corruption for some MTUs.

This is the grungy swap all the occurrences in the right places patch that
goes with the updates. At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to
begin turning new stuff on providing nobody reports lots of bugs
If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.
If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)
Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia

In order to sort out our struct termios and add proper speed control we need
to separate the kernel and user termios structures. Glibc is fine but the
other libraries rely on the kernel exported struct termios and we need to
extend this without breaking the ABI/API
To do so we add a struct ktermios which is the kernel view of a termios
structure and overlaps the struct termios with extra fields on the end for
now. (That limitation will go away in later patches). Some platforms (eg
alpha) planned ahead and thus use the same struct for both, others did not.
This just adds the structures but does not use them, it seems a sensible
splitting point for bisect if there are compile failures (not that I expect
them)

This allows workqueue users to run just their own pending work, rather
than wait for the whole workqueue to finish running. This solves the
deadlock with networking libphy that was due to other workqueue entries
possibly needing a lock that was held by the routine that wanted to
flush its own work.
It's not wonderful: if you absolutely need to synchronize with the work
function having been executed, any user strictly speaking should have
its own completion tracking logic, since when we run things explicitly
by hand, the generic workqueue layer can no longer help us synchronize.
Also, this is strictly only usable for work that has been scheduled
without any delayed timers. You can not mix the new interface with
schedule_delayed_work().
But it's better than what we had currently.

Pass struct dev pointer to dma_cache_sync()
dma_cache_sync() is ill-designed in that it does not have a struct device
pointer argument which makes proper support for systems that consist of a
mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync
to take a struct device pointer as first argument and fix all its callers
to pass it.
