8ad928d52e ACPI / PM: Use ACPI_STATE_D3_COLD instead of ACPI_STATE_D3 everywhere
There are several places in the tree where ACPI_STATE_D3 is used
instead of ACPI_STATE_D3_COLD which should be used instead for
clarity.  Modify them all to use ACPI_STATE_D3_COLD as appropriate.

[The definition of ACPI_STATE_D3 itself cannot go away at this point
 as it is part of ACPICA.]

02aa2a3763 drivers: avoid format string in dev_set_name
Calling dev_set_name with a single paramter causes it to be handled as a
format string.  Many callers are passing potentially dynamic string
content, so use "%s" in those cases to avoid any potential accidents,
including wrappers like device_create*() and bdi_register().

fe31edc8a3 Drivers: ide: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

9974e43d90 ide: fix generic_ide_suspend/resume Oops
This patch fixes a regresion introduced by commit 0998d063 (device-core: Ensure
drvdata = NULL when no driver is bound).

Suspend oopses in generic_ide_suspend() because dev_get_drvdata()

prepared for this.

Fix is based on Alan Stern's suggestion.

839e7306e5 IDE: Don't powerdown Compaq Triflex IDE device on suspend
Don't powerdown Compaq Triflex IDE device on suspend

This fixes APM suspend on Compaq Armada 7400.
APM BIOS doesn't suspend if IDE is powered down when suspending.
The Triflex controller is found only on old Compaq boards,
so this patch will hopefully have no side effects.

This patch fixes a suspend regression introduced in

2c8fc86760 ide-disk: Fix request requeuing
Simon Kirby reported that on his RAID setup with idedisk underneath
the box OOMs after a couple of days of runtime. Running with
CONFIG_DEBUG_KMEMLEAK pointed to idedisk_prep_fn() which unconditionally
allocates an ide_cmd struct. However, ide_requeue_and_plug() can be
called more than once per request, either from the request issue or the
IRQ handler path and do blk_peek_request() ends up in idedisk_prep_fn()
repeatedly, allocating a struct ide_cmd everytime and "forgetting" the
previous pointer.

Make sure the code reuses the old allocated chunk.

   legacy/fringe drivers")

 - 7eec77a181 ("ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd
   and ide-cd")

because of conflicts with the "g->flags" updates near-by by commit
d4dc210f69 ("block: don't block events on excl write for non-optical

As a result, we re-introduced the hanging behavior due to infinite disk
media change reports.

Tssk, tssk, people! Don't do back-merges at all, and *definitely* don't
do them to hide merge conflicts from me - especially as I'm likely

d4dc210f69 block: don't block events on excl write for non-optical devices
Disk event code automatically blocks events on excl write.  This is
primarily to avoid issuing polling commands while burning is in
progress.  This behavior doesn't fit other types of devices with
removeable media where polling commands don't have adverse side
effects and door locking usually doesn't exist.

This patch introduces new genhd flag which controls the auto-blocking
behavior and uses it to enable auto-blocking only on optical devices.

7eec77a181 ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd and ide-cd
check_events() implementations in both ide-gd and ide-cd are
inadequate for in-kernel event polling.  Both generate media change
events continuously when certain conditions are met causing infinite
event loop between the driver and userland event handler.

As disk event now supports suppression of unlisted events, simply
de-listing DISK_EVENT_MEDIA_CHANGE from disk->events resolves the
problem.  Internal handling around media revalidation will behave the
same while userland will fall back to userland event polling after
detecting the device doesn't support disk events.

7eaceaccab block: remove per-queue plugging
Code has been converted over to the new explicit on-stack plugging,
and delay users have been converted to use the new API for that.
So lets kill off the old plugging along with aops->sync_page().

5b03a1b140 ide: Convert to bdops->check_events()
Convert ->media_changed() to the new ->check_events() method.  The
conversion is mostly mechanical.  The only notable change is that
cdrom now doesn't generate any event if @slot_nr isn't CDSL_CURRENT.
It used to return -EINVAL which would be treated as media changed.  As
media changer isn't supported anyway, this doesn't make any
difference.

This makes ide emit the standard disk events and allows kernel event
polling.  Currently, only MEDIA_CHANGE event is implemented.  Adding
support for EJECT_REQUEST shouldn't be difficult; however, given that
ide driver is already deprecated, it probably is best to leave it
alone.

6a108a14fa kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

dd8717da6d ide: clean up timed out request handling
8f6205cd57 introduced a bug where a
timed out DMA request is never requeued and lost.
6072f7491f fixed this by making
ide_dma_timeout_retry() requeue the request itself.  While the fix is
correct, it makes DMA and non-DMA paths asymmetric regarding how the
in flight request is requeued.

As long as hwif->rq is set, the IDE driver is assuming ownership of
the request and the request should either be completed or requeued
when clearing hwif->rq.  In the timeout path, the ide driver holds
onto the request as long as the recovery action (ie. reset) is in
progress and clears it after the state machine is stopped (ide_stopped
return), so the existing requeueing logic is correct.  The bug
occurred because ide_dma_timeout_retry() explicitly clears hwif->rq
without requeueing it.

ide_dma_timeout_retry() is called only by ide_timer_expiry() and
returns ide_started only when ide_error() would return it - ie. after
reset state machine has started in which case the state machine will
eventually end up executing the ide_stopped path in ide_timer_expiry()
after reset protocol is complete.  So, there is no need to clear
hwif->rq from ide_dma_timeout_retry().  ide_timer_expiry() will handle
it the same way as PIO timeout path.

Kill hwif->rq clearing and requeueing from ide_dma_timeout_retry() and
let ide_timer_expiry() deal with it.  The end result should remain the
same.

grepping shows ide_dma_timeout_retry() is the only site which clears
hwif->rq without taking care of the request, so there shouldn't be
similar fallouts.

6038f373a3 llseek: automatically add .llseek fop
All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.

The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.

New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time.  Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.

The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.

Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.

Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

1ac71e5a35 pcmcia: convert pcmcia_request_configuration to pcmcia_enable_device
pcmcia_enable_device() now replaces pcmcia_request_configuration().
Instead of config_req_t, all necessary flags are either passed as
a parameter to pcmcia_enable_device(), or (in rare circumstances)
set in struct pcmcia_device -> flags.

With the last remaining user of include/pcmcia/cs.h gone, remove
all references.

7feabb6412 pcmcia: move config_{base,index,regs} to struct pcmcia_device
Several drivers prefer to explicitly set config_{base,index,regs},
formerly known as ConfigBase, ConfigIndex and Present. Instead of
passing these values inside config_req_t, store it in struct
pcmcia_device.

37979e1546 pcmcia: simplify IntType
IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO
(all other drivers). As this flags seems to relate to ioport access, make
it conditional to the driver having requested IO port access. There are two
drivers which do not request IO ports, but did set INT_MEMORY_AND_IO:
ray_cs and b43. For those, we consistently only set INT_MEMORY in future.
