The function sfi_map_memory/sfi_unmap_memory uses
early_ioremap/early_iounmap respectively, which refers to a __init
function. And function sfi_check_table also refers to a __init function
sfi_verify_table. Since the references are valid, so use __ref to get rid
of the warnings.

The ACPI /proc write() code takes an unsigned length argument like any write()
function, but then assigned it to a *signed* integer called "len".
Only after this is a sanity check for len done to make it not larger than 4.
Due to the type change a len < 0 is in principle also possible; this patch

Fixes for the DMA transfer mode of the driver to try and improve the state
of the code:
- Ensure that dma_complete is set during the end of the command phase
so that transfers do not stall awaiting the completion
- Update the DMA debugging to provide a bit more useful information
such as how many DMA descriptors where not processed and print the
DMA addresses in hexadecimal.
- Fix the DMA channel request code to actually request DMA for the
S3CMCI block instead of whatever '0' signified.
- Add fallback to PIO if we cannot get the DMA channel, as many of the
devices with this block only have a limited number of DMA channels.
- Only try and claim and free the DMA channel if we are trying to use it.
This improves the driver DMA code to the point where it can now identify a
card and read the partition table. However the DMA can still stall when
trying to move data between the host and memory.

The controller supports SDIO IRQ detection so add support for hardware
assisted SDIO interrupt detection for the SDIO core. This improves the
response time for SDIO interrupts and thus the transfer rate from devices
such as the Marvel 8686.
As a note, it does seem that the controller will miss an IRQ than is held
asserted, so there are some manual checks to see if the SDIO interrupt is
active after a transfer.

This is based on Michal Schmidt fix for skge.
Most network drivers request their IRQ when the interface is activated.
sky2 does it in ->probe() instead, because it can work with two-port
cards where the two net_devices use the same IRQ. This works fine most
of the time, except in some situations when the interface gets renamed.
Consider this example:
1. modprobe sky2
The card is detected as eth0 and requests IRQ 17. Directory
/proc/irq/17/eth0 is created.
2. There is an udev rule which says this interface should be called
eth1, so udev renames eth0 -> eth1.
3. modprobe 8139too
The Realtek card is detected as eth0. It will be using IRQ 17 too.
4. ip link set eth0 up
Now 8139too requests IRQ 17.
The result is:
WARNING: at fs/proc/generic.c:590 proc_register ...
proc_dir_entry '17/eth0' already registered
The fix is for sky2 to name the irq based on the pci device, as is done
by some other devices DRM, infiniband, ... ie. sky2@pci:0000:00:00

And "ls /proc/irq/17" shows two subdirectories, both called eth0.
Fix it by using a unique name for skge's IRQ, based on the PCI address.
The naming from the example then looks like this:
$ grep skge /proc/interrupts

prepare_discard_fn() was being called in a place where memory allocation
was effectively impossible. This makes it inappropriate for all but
the most trivial translations of Linux's DISCARD operation to the block
command set. Additionally adding a payload there makes the ownership
of the bio backing unclear as it's now allocated by the device driver
and not the submitter as usual.
It is replaced with QUEUE_FLAG_DISCARD which is used to indicate whether
the queue supports discard operations or not. blkdev_issue_discard now
allocates a one-page, sector-length payload which is the right thing
for the common ATA and SCSI implementations.
The mtd implementation of prepare_discard_fn() is replaced with simply
checking for the request being a discard.
Largely based on a previous patch from Matthew Wilcox <matthew@wil.cx>
which did the prepare_discard_fn but not the different payload allocation
yet.

to read the partitions, cciss_open will be called for each logical

then the reading of the partition information during the initial

As noticed by Alan Stern, there is still one issue with the driver:
we disable PCI IRQ on suspend, but other devices on the same IRQ
line might still need the IRQ enabled to suspend properly.
Nowadays, PCI core handles all power management work by itself, with
one condition though: if we use dev_pm_ops. So, rework the driver to
only quiesce 3c59x internal logic on suspend, while PCI core will
manage PCI device power state with IRQs disabled.

David Howells noticed (due to the compiler warning about an unused

that implements TIOCSPTLCK for legacy pty handling. It's been that way
since 2.6.26, commit 3e8e88ca05 to be
exact ("pty: prepare for tty->ops changes").
DavidH initially submitted a patch just removing the dead code entirely,
and since nobody has apparently ever complained, I'm not entirely sure
that wouldn't be the right thing to do. But since the whole and only
point of the legacy pty code is to be compatible with legacy distros
that don't use the new unix98 pty model, let's just wire it up again.
And clean it up a bit while we're at it.

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

When hardware or uCode problem occurs driver captures significant
information from device to enable debugging. The format of this information
is different between 3945 and 4965 and later devices, yet currently the
3945 uses the 4965 and later format. Fix this by adding a new library call
that is initialized to the correct formatting routine based on device.
This moves the iwlagn event and error log handling back to iwl-agn.c to
make it part of iwlagn module.

We keep track of where to write into a buffer by keeping a count of how
much has been written so far. When writing to the buffer we thus take the
buffer pointer and adding the count of what has been written so far.
Keeping track of what has been written so far is done by incrementing
this number every time something is written to the buffer with how much has
been written at that time.
Currently this number is incremented incorrectly when using the
"hex_dump_to_buffer" call to add data to the buffer. Fix this by only
adding what has been added to the buffer in that call instead of what has
been added since beginning of buffer.
Issue was discovered and discussed during testing of
https://bugzilla.redhat.com/show_bug.cgi?id=464598 .

The SPIC irq is not really shareable, the IO port cannot be cleared and
always returns some data so there is no real way to understand if the irq
is for us or not. Moreover the _PRS acpi method says the irq is not
shareable.
In addition to this, in some cases, an additional write to the IO port has
to be performed in order to properly decode the event received from the
device. This generates another interrupt which may overlap with the
previous one. In the future this is going to be important for properly
decoding events.

The following commit made console open fails while booting:
commit b50989dc44
Author: Alan Cox <alan@linux.intel.com>
Date: Sat Sep 19 13:13:22 2009 -0700
tty: make the kref destructor occur asynchronously
Due to tty release routines run in a workqueue now, error like the
following will be reported while booting:
INIT open /dev/console Input/output error
It also causes hibernation regression to appear as reported at
http://bugzilla.kernel.org/show_bug.cgi?id=14229
The reason is that now there's latency issue with closing, but when
we open a "closing not finished" tty, -EIO will be returned.
Fix it as per the following Alan's suggestion:
Fun but it's actually not a bug and the fix is wrong in itself as
the port may be closing but not yet being destructed, in which case
it seems to do the wrong thing. Opening a tty that is closing (and
could be closing for long periods) is supposed to return -EIO.
I suspect a better way to deal with this and keep the old console
timing is to split tty->shutdown into two functions.
tty->shutdown() - called synchronously just before we dump the tty
onto the waitqueue for destruction
tty->cleanup() - called when the destructor runs.
We would then do the shutdown part which can occur in IRQ context
fine, before queueing the rest of the release (from tty->magic = 0
... the end) to occur asynchronously
The USB update in -next would then need a call like
if (tty->cleanup)
tty->cleanup(tty);
at the top of the async function and the USB shutdown to be split
between shutdown and cleanup as the USB resource cleanup and final
tidy cannot occur synchronously as it needs to sleep.
In other words the logic becomes
final kref put
make object unfindable
async
clean it up

I was recently lucky enough to get a 64-CPU system, so my kernel log
ends up with 64 lines like:
ACPI: CPU0 (power states: C1[C1] C2[C3])
This is pretty useless clutter because this info is already available
after boot from both /sys/devices/system/cpu/cpu*/cpuidle/state?/ as
well as /proc/acpi/processor/CPU*/power.
So just delete the code that prints the C-states in processor_idle.c.

The message "ACPI: Device needs an ACPI driver" is misleading. The
device _may_ need an ACPI driver, if the BIOS implemented a custom
API for the device in question (which, AFAIK, can't be checked.) If
not, then either a generic ACPI driver may be used (for example
"thermal"), or nothing can be done (other than a white list).
I propose to reword the message to:
ACPI: If an ACPI driver is available for this device, you should use
it instead of the native driver
which I think is more correct. Comments and suggestions welcome.
I also added a message warning about possible problems and system
instability when users pass acpi_enforce_resources=lax, as suggested
by Len.
