This patch adds a new driver for "Option" cards. This is a GSM data card,
controlled by three "serial ports" which are connected via an OHCI adapter,
all located on an oversized PC-Card. It's sold by several GSM service
providers.

Traditionally, this card has been accessed via the standard serial driver
and appropriate vendor= and product= options. However, testing has
revealed several problems with this approach, including hung data transfers
and lost data blocks when receiving.

Therefore, I've written a separate driver.

Instead of going to the complexity of using a thread info bit, just set and

Fix a bug in list scanning that can cause us to skip the last buffer on the
checkpoint list (and hence fail to do any progress under some rather
unfavorable conditions).

The problem is we first do jh=next_jh and then test

} while (jh!=last_jh);

Hence we skip the last buffer on the list (if it was not the only buffer on
the list). As we already do jh=next_jh; in the beginning of the loop we
are safe to just remove the assignment in the end. It can happen that 'jh'
will be freed at the point we test jh != last_jh but that does not matter
as we never *dereference* the pointer.

Firstly, if the direction is TODEVICE, then dirty data in the
streaming cache is impossible so we can elide the flush-flag
synchronization in that case.

Next, the context allocator is broken. It is highly likely
that contexts get used multiple times for different dma
mappings, which confuses the strbuf flushing code and makes
it run inefficiently.

Avoid console spam with ext3 aborted journal.

ext3 usually reports error conditions that it detects in its environment.
But when its journal gets aborted due to such errors, it can sometimes
continue to report that condition forever, spamming the console to such
an extent that the initial first cause of the journal abort can be lost.

When the journal aborts, we put the filesystem into readonly mode. Most
subsequent filesystem operations will get rejected immediately by checks
for MS_RDONLY either in the filesystem or in the VFS. But some paths do
not have such checks --- for example, if we continue to write to a file
handle that was opened before the fs went readonly. (We only check for
the ROFS condition when the file is first opened.) In these cases, we
can continue to generate log errors similar to

EXT3-fs error (device $DEV) in start_transaction: Journal has aborted

for each subsequent write.

There is really no point in generating these errors after the initial
error has been fully reported. Specifically, if we're starting a
completely new filesystem operation, and the filesystem is *already*
readonly (ie. the ext3 layer has already detected and handled the
underlying jbd abort), and we see an EROFS error, then there is simply
no point in reporting it again.

The driver model has a "detach_state" mechanism that:

- Has never been used by any in-kernel drive;
- Is superfluous, since driver remove() methods can do the same thing;
- Became buggy when the suspend() parameter changed semantics and type;
- Could self-deadlock when called from certain suspend contexts;
- Is effectively wasted documentation, object code, and headspace.

This removes that "detach_state" mechanism; net code shrink, as well
as a per-device saving in the driver model and sysfs.

This patch fixes "grave" bugs in i2c-ali1563 driver. It seems on recent
chipset revisions the HSTS_DONE is set only for block transfers, so we
must detect the end of ordinary transaction other way. Also due to missing
and mask, setting other transfer modes was not possible. Moreover the
continous byte mode transfer uses DAT0 for command rather than CMD command.
All those changes were tested with help of Chunhao Huang from Winbond.

I'm willing to maintain the driver. Second patch adds me as maintainer
if this is neccessary.

Even after the previous fix you can still set CONFIG_ACPI_BOOT
indirectly even without CONFIG_ACPI by choosing CONFIG_PCI and
CONFIG_PCI_MMCONFIG.

That doesn't build very well either.

This makes PCI_MMCONFIG depend on ACPI, fixing that hole.

[ I guess in theory Kconfig could follow the whole chain of dependencies
for things that get selected, but that sounds insanely complicated, so
we'll just fix up these things by hand. --Linus ]
