As a replacement to pcmcia_get_{first,next}_tuple() and
pcmcia_get_tuple_data(), three new -- and easier to use --
functions are added:
- pcmcia_get_tuple() to get the very first CIS entry of one
type.
- pcmcia_loop_tuple() to loop over all CIS entries of one type.
- pcmcia_get_mac_from_cis() to read out the hardware MAC address
from CISTPL_FUNCE.
Only a handful of drivers need these functions anyway, as most
CIS access is already handled by pcmcia_loop_config(), which
now shares the same backed (pccard_loop_tuple()) with
pcmcia_loop_tuple().
A pcmcia_get_mac_from_cis() bug noted by Komuro
<komurojun-mbn@nifty.com> has been fixed in this revision.

For non hotplug PCI devices, the system firmware usually configures
CLS correctly. For pccard devices system firmware can't do it and
Linux PCI layer doesn't do it either. Unfortunately this leads to
poor performance for certain devices (sata_sil). Unless MWI, which
requires separate configuration, is to be used, CLS doesn't affect
correctness, so the configuration should be harmless.
This patch makes pci_set_cacheline_size() always built and export it
and make pccard call it during attach.
Please note that some other PCI hotplug drivers (shpchp and pciehp)
also configure CLS on hotplug.

Commit 0c570cdeb8
(PM / yenta: Fix cardbus suspend/resume regression) caused resume to
fail on systems with two CardBus bridges. While the exact nature
of the failure is not known at the moment, it can be worked around by
splitting the yenta resume into an early part, executed during the
early phase of resume, that will only resume the socket and power it
up if there was a card in it during suspend, and a late part,
executed during "regular" resume, that will carry out all of the
remaining yenta resume operations.
Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14334, which is a
listed regression from 2.6.31.

pccard_read_tuple(), which is only used by the PCMCIA core, should
handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which
may be 0) is requested, set tuple.Attributes = 0 as was done in all
PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the
"common" tuple. As to the callers of pccard_read_tuple():
- All calls to pcmcia_validate_cis() had set the "function" parameter to
BIND_FN_ALL. Therefore, remove the "function" parameter and make the
parameter to pccard_read_tuple explicit.
- Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL. This was
already the case for calls to CISTPL_LONGLINK_MFC.

Since 2.6.29 the PCI PM core have been restoring the standard
configuration registers of PCI devices in the early phase of
resume. In particular, PCI devices without drivers have been handled
this way since commit 355a72d75b
(PCI: Rework default handling of suspend and resume). Unfortunately,
this leads to post-resume problems with CardBus devices which cannot
be accessed in the early phase of resume, because the sockets they
are on have not been woken up yet at that point.
To solve this problem, move the yenta socket resume to the early
phase of resume and, analogously, move the suspend of it to the late
phase of suspend. Additionally, remove some unnecessary PCI code
from the yenta socket's resume routine.
Fixes http://bugzilla.kernel.org/show_bug.cgi?id=13092, which is a
post-2.6.28 regression.

"Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data

device driver's suspend_late() function or other hard to

PCMCIA abuses dev->private_data in the probe methods. Unfortunately it
continues to abuse it after calling drv->probe() which leads to crashes and
other nasties (such as bogus probes of multifunction devices) giving errors like
pcmcia: registering new device pcmcia0.1
kernel: 0.1: GetNextTuple: No more items
Extract the passed data before calling the driver probe function that way
we don't blow up when the driver reuses dev->private_data as its right.
As its close to the final release just move the hack so it works out,
hopefully someone will be sufficiently embarrassed to produce a nice rework
for 2.6.28.

The Arcom/Eurotech Viper needs some extra care to run. On this board,
the PC104 connector is actually wired to the second PCMCIA slot.
Therefore, this second socket needs to be enabled, despite not being

for example, use the PC104 bus without having the PCMCIA module loaded.

On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit
boundary. For example:
u64 val = PAGE_ALIGN(size);
always returns a value < 4GB even if size is greater than 4GB.
The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for
example):
#define PAGE_SHIFT 12
#define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT)
#define PAGE_MASK (~(PAGE_SIZE-1))
...
#define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK)
The "~" is performed on a 32-bit value, so everything in "and" with
PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary.
Using the ALIGN() macro seems to be the right way, because it uses
typeof(addr) for the mask.
Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in
include/linux/mm.h.

two reasons:
1. GPIO namings and their mode definitions are conceptually not part
of the PXA register definitions
2. this is actually a temporary move in the transition of PXA2xx to
use MFP-alike APIs (as what PXA3xx is now doing), so that legacy
code will still work and new code can be added in step by step

of_iomap calls ioremap, and so should be matched with an iounmap. At the
two error returns, the result of calling of_iomap is only stored in a local
variable, so these error paths need to call iounmap. Furthermore, this
function ultimately stores the result of of_iomap in an array that is local
to the file. These values should be iounmapped at some point. I have
added a corresponding call to iounmap at the end of the function
m8xx_remove.

Convert the io_req_t members to unsigned int, to allow use on machines with
more than 16 bits worth of IO ports (i.e. secondary busses on ppc64, etc).
There was only a couple of places in drivers where a change was needed. I
left printk formats alone (there are lots of %04x-style formats in there),
mostly to not change the format on the platforms that only have 16-bit io
addresses, but also because the padding doesn't really add all that much value
most of the time.
I found only one sprintf of an address, and upsized the string accordingly (I
doubt anyone will have anywhere near INT_MAX as irq value, but at least
there's room for it now).

to do one modification to drivers/pcmcia/pxa2xx_base.c to get the interface
working with orinoco gold PCMCIA card (wired pcnet_cs ethernet card worked
even without this modification).
The issue has something to do with assert time on PCMCIA bus, but I'm not
really sure what -- I found the working value just by trial&error approach.
I'm not sure how is the assert value in pxa2xx_mcxx_asst calculated (I
know, simple formula, but the reason why is it calculated that way is not
obvious for me), neither that my modification is correct. It just works
with iPAQ.

Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves. This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.
It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.
The patch causes all kernel threads to be nonfreezable by default (ie. to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE. It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear. Additionally, it updates documentation to
describe the freezing of tasks more accurately.

Well, first of all, I don't want to change so many files either.
What I do:
Adding a new parameter "struct bin_attribute *" in the
.read/.write methods for the sysfs binary attributes.
In fact, only the four lines change in fs/sysfs/bin.c and
include/linux/sysfs.h do the real work.
But I have to update all the files that use binary attributes
to make them compatible with the new .read and .write methods.
I'm not sure if I missed any. :(
Why I do this:
For a sysfs attribute, we can get a pointer pointing to the
struct attribute in the .show/.store method,
while we can't do this for the binary attributes.
I don't know why this is different, but this does make it not
so handy to use the binary attributes as the regular ones.
So I think this patch is reasonable. :)
Who benefits from it:
The patch that exposes ACPI tables in sysfs
requires such an improvement.
All the table binary attributes share the same .read method.
Parameter "struct bin_attribute *" is used to get
the table signature and instance number which are used to
distinguish different ACPI table binary attributes.
Without this parameter, we need to offer different .read methods
for different ACPI table binary attributes.
This is impossible as there are various ACPI tables on different
platforms, and we don't know what they are until they are loaded.

sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.
This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.

of_device, so only arch/powerpc stuff is capable to use it, which now implies
only mpc885ads reference board.
To cope with the code that should be hooked inside driver, but is really board
specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds
necessary function pointers that are filled in the BSP code.

Fix enable_irq_wake and disable_irq_wake symmetry in at91 pcmcia driver
disable_irq_wake call must be symmetric with enable_irq_wake. This patch
fix that problem for the at91_pcmia driver. It seems that this patch was
forgotten when we've fixed irq_wake symmetry in all at91 related drivers.
It was discussed in the "at91 drivers and [enable/disable]_irq_wake
(wrong?) usage" thread on the linux-arm-kernel mailing list.

We've had various reports of some legacy "probe the hardware" style
platform drivers having nasty problems with hotplug support.
The core issue is that those legacy drivers don't fully conform to the
driver model. They assume a role that should be the responsibility of
infrastructure code: creating device nodes.
The "modprobe" step in hotplugging relies on drivers to have split those
roles into different modules. The lack of this split causes the problems.
When a driver creates nodes for devices that don't exist (sending a hotplug
event), then exits (aborting one modprobe) before the "modprobe $MODALIAS"
step completes (by failing, since it's in the middle of a modprobe), the
result can be an endless loop of modprobe invocations ... badness.
This fix uses the newish per-device flag controlling issuance of "add"
events. (A previous version of this patch used a per-device "driver can
hotplug" flag, which only scrubbed $MODALIAS from the environment rather
than suppressing the entire hotplug event.) It also shrinks that flag to
one bit, saving a word in "struct device".
So the net of this patch is removing some nasty failures with legacy
drivers, while retaining hotplug capability for the majority of platform
drivers.

PCI drivers have the new_id file in sysfs which allows new IDs to be added
at runtime. The advantage is to avoid re-compilation of a driver that
works for a new device, but it's ID table doesn't contain the new device.
This mechanism is only meant for testing, after the driver has been tested
successfully, the ID should be added in source code so that new revisions
of the kernel automatically detect the device.
The implementation follows the PCI implementation. The interface is documented
in Documentation/pcmcia/driver.txt. Computations should be done in userspace,
so the sysfs string contains the raw structure members for matching.

This is a minor correctness fix: since the at91_cf driver probe() routine
is in the init section, it should use platform_driver_probe() instead of
leaving that pointer around in the driver struct after init section
removal.

I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.
In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.
My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.

Convert omap_cf into a platform_driver ... this resolves oopsing during
suspend/resume.
Evidently folk haven't tried suspend/resume on an OSK (the main platform
for this driver) since September or so, which is when platform_device
learned about suspend_late()/resume_early() and stopped being able to
suspend/resume without a platform_driver.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).
