After mmc_block's remove function has exited, we must not
touch the card structure in any way. This means we not only
must remove the gendisk, we must also flush out any
remaning requests already queued up.
We previously removed the disk, but didn't flush it,
causing oops:es when removing a card in the middle of a

The SDHCI spec implies that is is incorrect to set a clock
frequency above 25 MHz without setting the high speed bit.
Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
Modern SD cards support a clock speed of 50 MHz. Make sure we test for
this capability and do the song and dance required to activate it.
Activating high speed support actually modifies the TRAN_SPEED field
of the CSD. But as the spec says that the cards must report 50 MHz,
we might as well skip re-reading the CSD.

Several fixes for mmc_delay():
* Repair if-clause that was supposed to detect sub-hz delays.
* Change yield() to cond_resched() as yield() no longer has the
semantics we desire.
* mmc_delay() is used to guarantee protocol delays, so we cannot
return early (i.e. use _interruptable).

This change adds support for the mmc4 4-bit wide-bus mode.
The mmc4 spec defines 8-bit and 4-bit transfer modes. As we do not support
any 8-bit hardware, this patch only adds support for the 4-bit mode, but
it can easily be built upon when the time comes.
The 4-bit mode is electrically compatible with SD's 4-bit mode but the
procedure for turning it on is different. This patch implements only
the essential parts of the procedure as defined by the spec. Two additional
steps are recommended but not compulsory. I am documenting them here so
that there's a record.
1) A bus-test mechanism is implemented using dedicated mmc commands which allow
for testing the functionality of the data bus at the electrical level. This is
pretty paranoid and they way the commands work is not compatible with the mmc
subsystem (they don't set valid CRC values).
2) MMC v4 cards can indicate they would like to draw more than the default
amount of current in wide-bus modes. We currently will never switch the card
into a higher draw mode. Supposedly, allowing the card to draw more current
will let it perform better, but the specs seem to indicate that the card will
function correctly without the mode change. Empirical testing supports this
interpretation.

This adds support for the high-speed modes defined by mmc v4
(assuming the host controller is up to it). On a TI sdhci controller,
it improves read speed from 1.3MBps to 2.3MBps. The TI controller can
only go up to 24MHz, but everything helps. Another person has taken
this basic patch and used it on a Nokia 770 to get a bigger boost
because that controller can run at 48MHZ.

JMicron AHCI controllers set PORT_IRQ_IF_ERR on device errors. The
IRQ status bit indicates interface error or protocol mismatch and ahci
driver interprets it into AC_ERR_ATA_BUS. So, whenever an ATAPI
device raises check condition, ahci interprets it as ATA bus error and
thus resets it which, in turn, raises check condition thus creating a
reset loop and rendering the device unuseable.
This patch makes JMB controllers ignore PORT_IRQ_IF_ERR when

- Some callers to rtc_update_irq() were not ensuring IRQs were blocked,

Not all graphic page remappers support physical addresses over the 4GB
mark for remapping, so while some do (the AMD64 GART always did, and I
just fixed the i965 to do so properly), we're safest off just forcing
GFP_DMA32 allocations to make sure graphics pages get allocated in the
low 32-bit address space by default.
AGP sub-drivers that really care, and can do better, could just choose
to implement their own allocator (or we could add another "64-bit safe"
default allocator for their use), but quite frankly, you're not likely
to care in practice.
So for now, this trivial change means that we won't be allocating pages
that we can't map correctly by mistake on x86-64.
[ On traditional 32-bit x86, this could never happen, because GFP_KERNEL
would never allocate any highmem memory anyway ]

This introduces a i965-specific "mask_memory()" function that knows
about the extended physical addresses that the i965 supports. This
allows us to correctly map in physical memory in the >4GB range into the
GTT.
Also simplify/clean-up the i965 case for the aperture sizing by just
returning the fixed 512kB size from "fetch_size()". We don't really
care that not all of the aperture may be visible - the only thing that
cares about the aperture size is the Intel "stolen memory" calculation,
which depends on the fixed size.

This is a quick hack to overcome the fact that SRCU currently does not

Currently we don't allow this at all for modules, and the only user that
needs is right now is cpufreq. As reported by Thomas Gleixner:

This same bug has now been introduced twice: it was done earlier by
commit b8d35192c5, only to be reverted
last time in commit 72945b2b90.
We must NOT try to queue up notify handlers to another thread than the
normal ACPI execution thread, because the notifications on some systems
seem to just keep on accumulating until we run out of memory and/or
threads.
Keeping events within the one deferred execution thread automatically
throttles the events properly.
At least the Compaq N620c will lock up completely on the first thermal

A curious thing happens, however, when ata_qc_new_init fails to get
an ata_queued_cmd:
First, ata_qc_new_init handles the failure like this:
cmd->result = (DID_OK << 16) | (QUEUE_FULL << 1);
done(cmd);
Then, we return to ata_scsi_translate and do this:
err_mem:
cmd->result = (DID_ERROR << 16);
done(cmd);
It appears to me that first we set a status code indicating that we're
ok but the device queue is full and finish the command, but then
we blow away that status code and replace it with an error flag and
finish the command a second time! That does not seem to be desirable
behavior since we merely want the I/O to wait until a command slot
frees up, not send errors up the block layer.
In the err_mem case, we should simply exit out of ata_scsi_translate
instead.

When ib_cancel_mad() is called, it puts the canceled send on a list
and schedules a "flushed" callback from process context. However,
this leaves a window where a receive completion could be processed
before the send is fully flushed.
This is fine, except that ib_find_send_mad() will find the MAD and
return it to the receive processing, which results in the sender
getting both a successful receive and a "flushed" send completion for
the same request. Understandably, this confuses the sender, which is
expecting only one of these two callbacks, and leads to grief such as
a use-after-free in IPoIB.
Fix this by changing ib_find_send_mad() to return a send struct only
if the status is still successful (and not "flushed"). The search of
the send_list already had this check, so this patch just adds the same
check to the search of the wait_list.

Fix MSPEC driver to build for non SN2 enabled configs as the driver should
work in cached and uncached modes (no fetchop) on these systems. In
addition make MSPEC select IA64_UNCACHED_ALLOCATOR, which is required for
it and move it to arch/ia64/Kconfig to avoid warnings on non ia64
architectures running allmodconfig. Once the Kconfig code is fixed, we can
move it back.

The PCI sysfs attributes are created after the initial PCI bus scan. With
the addition of more return value checking and assertions in the device and
sysfs layers we now can get dumps like this on sparc64:

It's triggering because removal of the "config" PCI sysfs file for the
device fails.
On sparc64, after probing the device, we'll delete the PCI device via
pci_remove_bus_device() if we cannot find the firmware device tree node
corresponding to it.
This is fine, but at this point the sysfs files for the PCI device won't be
setup yet.
So we should not try to do anything in pci_remove_sysfs_dev_files() if
pci_sysfs_init() has not run yet.

If there's a swap file on a software RAID, it should be possible to use this

For the above reasons it seems that md_threads should not be frozen during the

There is a race between dev_create() and find_device().
If the mdptr has not yet been stored against a device, find_device() needs to
behave as though no device was found. It already returns NULL, but there is a
dm_put() missing: it must drop the reference dm_get_md() took.
The bug was introduced by dm-fix-mapped-device-ref-counting.patch.
It manifests itself if another dm ioctl attempts to reference a newly-created
device while the device creation ioctl is still running. The consequence is
that the device cannot be removed until the machine is rebooted. Certain udev

This fixes a bug reported in:
http://bugzilla.kernel.org/show_bug.cgi?id=7438
tg3_close() turns off the PHY if WoL and ASF are both disabled. On
the next tg3_open(), some devices such as the 5752M will not be
brought up correctly without a PHY reset early in the reset sequence.
The PHY clock is needed for some internal MAC blocks to function
correctly.
This problem is fixed by always resetting the PHY early in
tg3_reset_hw() when it is called from tg3_open() or tg3_resume().
tg3_setup_phy() can then be called later in the sequence without the
reset_phy parameter set to 1, since the PHY reset is already done.

Fix mcs7830 patch
The recent mcs7830 update to make the MII support sharable goofed various
pre-existing configurations in two ways:
- it made the usbnet infrastructure reference MII symbols even
when they're not needed in the kernel being built
- it didn't enable MII along with the mcs7830 minidriver
This patch fixes these two problems.
However, there does seem to be a Kconfig reverse dependency bug in that MII
gets wrongly enabled in some cases (like USBNET=y and USBNET_MII=n); I think
I've noticed that same problem in other situations too. So the result can
mean kernels being bloated by stuff that's needlessly enabled ... better
than wrongly being disabled, but contributing to bloat.

When a front-end is disabled, card drivers that use it are compiled with
a stub version of the front-end's attach function. This way they have no
references to the front-end's code and don't need it to be loaded.
If a card driver is compiled into the kernel, and a front-end is a
module, then that front-end is effectively disabled wrt the card driver.
In this case, the card driver should get the stub version. This was not
happening.
The stub vs real attach function selection is changed so that when the
front-end is a module the real attach function is only used if the card
driver is a module as well. This means a module front-end will be
supported by card drivers that are modules and not supported by card
drivers compiled into the kernel.

The IR chip has no address decoding, so the IR data is always present in
the high byte when doing a read from the saa7146 chip. This means that
the DEBI address used is irrelevant to the IR decoding logic.
DEBI addresses 0x1XXX are mapped to the registers on the CI module
itself, but only the lowest two bits are actually used (see EN50221,
section A.2.2.1), meaning that 0x1234 is equivalent to 0x1000 which maps
to register 0 (the data register). A read from the data register is
supposed to be preceded by a read from the size register, so some CI
modules will be confused (the AlphaCrypt CAM will hang completely).
The attached patch changes the address used when reading the IR data to
use 0x4000 instead. This is the CI version address, which is a safer
default, works with the AlphaCrypt CAM and matches the behaviour of the
Windows driver (AFAIK).

[PATCH] libata: unexport ata_dev_revalidate()
[PATCH] Add 0x7110 piix to ata_piix.c
[PATCH] sata_sis: fix flags handling for the secondary port
This patch fixes a few issues in offb:
- A test was inverted causing the palette hack to never work
(no device node was passed down to the init function)
- Some cards seem to have their assigned-addresses property in a random
order, thus we need to try using of_get_pci_address() first, which will
fail if it's not a PCI device, and fallback to of_get_address() in that
case. of_get_pci_address() properly parsees assigned-addresses to test
the BAR number and thus will get it right whatever the order is.
- Some cards (like GXT4500) provide a linebytes of 0xffffffff in the
device-tree which does no good. This patch handles that by using the
screen width when that happens. (Also fixes btext.c while at it).
- Add detection of the GXT4500 in addition to the GXT2000 for the
palette hacks (we use the same hack, palette is linear in register space
at offset 0x6000).

This fixes a netdev watchdog timeout problem.
The software needs to call netif_tx_disable before running the
hardware calibration code. The problem condition can be shown by the
following timegraph.
|---5secs - ~10 jiffies time---|---|OOPS
^ ^
last real TX periodic work stops netif
At OOPS, the following happens:
The watchdog timer triggers, because the timeout of 5secs
is over. The watchdog first checks for stopped TX.
_Usually_ TX is only stopped from the TX handler to indicate
a full TX queue. But this is different. We need to stop TX here,
regardless of the TX queue state. So the watchdog recognizes
the stopped device and assumes it is stopped due to full
TX queues (Which is a _wrong_ assumption in this case). It then
tests how far the last TX has been in the past. If it's more than
5secs (which is the case for low or no traffic), it will fire
a TX timeout.

The length of the manfid CIS should be at least 4, and it's normally 4.
It's incorrect to require it to be at least 5. This breaks support for
most (if not all) cards.
The right place to ensure that we don't access beyond the CIS buffer is
to strengthen another check. Make sure that the next tuple begins at
least at the CIS buffer end (in which case we stop processing) or
before that.

about the relationship between network device and NAPI that aren't correct
on the second port, this will cause the port to never clear work.
Most systems, just have single port, so not a big issue.

Ray Lehtiniemi reported that an incoming UDP packet flood can lock up
the ep93xx ethernet driver. Herbert Valerio Riedel noted that due to
the way ep93xx_eth manages the RX/TXstatus rings, it cannot distinguish
a full ring from an empty one, and correctly suggested that this was
likely to be causing this lockup to occur.
Instead of looking at the hardware's RX/TXstatus ring write pointers
to determine when to stop reading from those rings, we should just check
every individual RX/TXstatus descriptor's valid bit instead, since there
is no other way to distinguish an empty ring from a full ring, and if
there is a descriptor waiting, we take the hit of reading the descriptor
from memory anyway.

This reverts commit a2b98a697f.
As per Guennadi Liakhovetski, the mac address change support code breaks
some normal uses (_without_ any address changes), and until it's all
sorted out, we're better off without it.
Says Francois:
"Go revert it.
Despite what I claimed, I can not find a third-party confirmation by
email that it works elsewhere.
It would probably be enough to remove the call to
__rtl8169_set_mac_addr() in rtl8169_hw_start() though."

The PXA2xx PCMCIA driver was registering a device_driver with the

The multithreaded-probing code has a problem: after one initcall level (eg,
core_initcall) has been processed, we will then start processing the next
level (postcore_initcall) while the kernel threads which are handling
core_initcall are still executing. This breaks the guarantees which the
layered initcalls previously gave us.
IOW, we want to be multithreaded _within_ an initcall level, but not between
different levels.
Fix that up by causing the probing code to wait for all outstanding probes at
one level to complete before we start processing the next level.

Considering below scenario:
1.Unload a PCI device's driver, the device ->current remains in PCI_D0.
2.Do suspend/resume circle. After that, BIOS puts the device to D3.
3.Reload the device driver. The calling pci_set_power_state in the
driver can't change the state to D0, as set_power_state thinks the
device is already in D0.
A bug is reported at http://bugzilla.kernel.org/show_bug.cgi?id=6024
Pat attached a patch at
http://marc.theaimsgroup.com/?l=linux-pci&m=114049761428561&w=2 for this
issue, but it's lost. As pci_set_power_state can handle D3 -> D0
correctly (restore config space), I simplified Patrick's patch.
