Sony laptops apparently write 4-bytes (rather than 1 byte)
to debug port 0x80, which spews error messages:
Denied AML access to port 0x00000080/4 (DMA1 0x0081-0x0083) [20090320]

> BUG: unable to handle kernel NULL pointer dereference at (null)
What happens is that the battery module's init sections are being freed
before the async callback (which was marked __init) has run. This theory
is supported by the fact that the bad RIP value is a vmalloc address.
The immediate fix is to make this a non-init call.
(A better long-term fix is of course to wait with init-section unloading
until a module's async initcalls have been run, which would allow us to
discard this function which is still only run once, after all. Perhaps a
new async_initcall() function for the async/module API, if this is needed
for other modules in the future?)

This makes the defautl ext3 data ordering mode (when no explicit
ordering is set) configurable, so as to allow people to default to
'data=writeback' and get the resulting latency improvements.
This is a non-issue if a filesystem has been explicitly set to some
ordering (with 'tune2fs').

There are various bits of code here that are unfinished and instead of
being harmless either confuse or spew stuff into the logs at higher than

mxser_check_modem_status is called with tty parameter, so the
reference should be increased by callers already -- for ioctl
syscall it is held whole time gap since open to close, for
interrupt, the reference count is increased in the irq handler.
There is no tty_kref_put in that function, so this also fixes
a refcounting bug.
