Reimplement handling of barrier requests.
* Flexible handling to deal with various capabilities of
target devices.
* Retry support for falling back.
* Tagged queues which don't support ordered tag can do ordered.Signed-off-by: Tejun Heo

Separate out bio initialization part from __make_request. It
will be used by the following blk_ordered_reimpl.Signed-off-by: Tejun Heo

add @uptodate argument to end_that_request_last() and @error
to rq_end_io_fn(). there's no generic way to pass error code
to request completion function, making generic error handling
of non-fs request difficult (rq->errors is driver-specific and
each driver uses it differently). this patch adds @uptodate
to end_that_request_last() and @error to rq_end_io_fn().for fs requests, this doesn't really matter, so just using the
same uptodate argument used in the last call to
end_that_request_first() should suffice. imho, this can also
help the generic command-carrying request jens is working on.Signed-off-by: tejun heo

the patch below marks various read-only variables in block/* as const,
so that gcc can optimize the use of them; eg gcc will replace the use by
the value directly now and will even remove the memory usage of these.Signed-off-by: Arjan van de Ven

For filesystems with a blocksize < page size, we can merge same page
calls into the bio_vec at the end of the bio. This saves segments
on systems with a page size > the "normal" 4kb fs block size.Signed-off-by: Christoph Hellwig

streamline a few other things in this area.Signed-off-by: Jens Axboe

Unlike other ioscheds, as-iosched handles alias by chaing them using
rq->queuelist. As aliased requests are very rare in the first place,
this complicates merge/dispatch handling without meaningful
performance improvement. This patch updates as-iosched to dump
aliased requests into dispatch queue as other ioscheds do.Signed-off-by: Tejun Heo

Setting RF (resume flag) allows a debugger to resume execution after a
code breakpoint without tripping the breakpoint again. It is reset by
the CPU after execution of one instruction.Requested by Stephane Eranian:
"I am trying to the user HW debug registers on i386 and I am running
into a problem with ptrace() not allowing access to EFLAGS_RF for
POKEUSER (see FLAG_MASK). [ ... ] It avoids the need to remove the
breakpoint, single step, and reinstall. The equivalent functionality
exists on IA-64 and is allowed by ptrace()"Cc: Stephane Eranian

Export the stored values instead of re-reading everything in the socket

This adds PCMCIA support for both MPC885ADS and MPC866ADS.
This is established not together with FADS, because 885 does not have
io_block_mapping() for BCSR area.
Also, some cleanups done both for 885ADS and MBX.Signed-off-by: Vitaly Bordug

Some PCMCIA sockets have statically mapped memory windows, but dynamically
mapped IO windows. Using the "nonstatic" socket library is inpractical for
them, as they do neither need a resource database (as we can trust the
kernel resource database on m68k and ppc) nor lots of other features of that
library. Let them get a small "iodyn" socket library (105 lines of code)
instead.Signed-off-by: Dominik Brodowski

Update the PCMCIA sound drivers to handle the recent changes to the PCMCIA
core. A part of this merge was done by Takashi Iwai .Signed-off-by: Dominik Brodowski

Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:int (*probe) (struct pcmcia_device *dev);
void (*remove) (struct pcmcia_device *dev);int (*suspend) (struct pcmcia_device *dev);
int (*resume) (struct pcmcia_device *dev);Signed-off-by: Dominik Brodowski

The linked list of devices managed by each PCMCIA driver is, in very most
cases, unused. Therefore, remove it from many drivers.Signed-off-by: Dominik Brodowski

Remove the old "detach" mechanism as it is unused now.

Unify the "detach" and REMOVAL_EVENT handlers to one "remove" function.

Merge the suspend and resume methods for 16-bit PCMCIA cards into the
device model -- for both runtime power management and suspend to ram/disk.Bugfix in ds.c by Richard Purdie

Move the suspend and resume methods out of the event handler, and into
special functions. Also use these functions for pre- and post-reset, as
almost all drivers already do, and the remaining ones can easily be
converted.Bugfix to include/pcmcia/ds.c
