This fixes a bug that happens when a request gets to the IDE layer for a
drive using ide-default (that is with no subdriver attached), like a
Power Management request.  In this case, the core will wait for the
device status to match drive->read_stat, but that field contains by
default a value that is not suitable for ATAPI devices.  This patch
fixes it.

This allows us to maintain quirks or capabilities on a per-port basis,
so we can handle buggy clones more effectively.

The dependencies for CONFIG_SERIAL_CORE / CONFIG_SERIAL_CORE_CONSOLE
were becoming very messy.  This cset converts the dependencies to
use "select" statements instead.

Since the driver model has transitioned away from using multi-level
device suspend/resume, we also drop the multi-level support from
the serial layer.

Update the 8250 and sa1100 drivers for this change.

Here's a patch to update the RxRPC driver. Most of it is CodingStyle fixes,
but it also includes a few miscellaneous bug fixes. stdint types are also
turned into C99 forms (eg: u32 -> uint32_t).

Benh saw some bugs where the queue would end up being in an invalid
state, and this could certainly explain one of them. We must not have a
stopped queue on the plug list, and blk_plug_device() right now will
happily plug a stopped queue.

We don't need to have it plugged either, blk_start_queue() will make
sure that request_fn gets run.

Code that includes seq_file.h uses a magic pointer "(void*)1"
to start a header seq_printf.

This patch adds a #define, so that people can start writing more
readable code.

This should fix the "ifconfig down ...  ifconfig up" problems some
people have seen.

Don't use C++ "argument declarations anywhere" in the kernel, even if
newer versions of gcc accept it.

For some reason, we had a structure field called 'current'.  This patch
fixes that.

Fix a couple of sn2 files.

Update the SA11x0 serial driver for the removal of system devices
from the driver model.  The driver becomes a platform device driver.
The driver is now known to the driver model and resource subsytems
as "sa11x0-uart".

	away static variables with no compiler-visible use.

This patch eliminates two unused SN2 header files:
include/asm-ia64/sn/klclock.h and include/asm-ia64/sn/ioc3.h.

Without this, if elv_try_last_merge() returns nonzero, we do not
initialise *req.  That results in a subsequent BUG_ON() in
__make_request() because req is NULL (or is just uninitialised).

Last round of changes broke sdla build if not a module.

drivers whose microcode load ioctl's used types with sizes that
overflow the ioctl number. Mark them _IOx_BAD() to document the fact.

This new version works with all compiler versions, and also catches the
case where somebody tries to pass in an array as an argument to the
ioctl macros.  Thus we verify that only proper types are used.

I have checked now that the object code for arch/s390/kernel/compat_ioctl.o
remains identical and that the whole kernel compiles for s390 and i386,
after fixing the broken ioctl numbers.
