this patch turns the netdev timeout WARN_ON_ONCE() into a WARN_ONCE(),
so that the device and driver names are inside the warning message.
This helps automated tools like kerneloops.org to collect the data
and do statistics, as well as making it more likely that humans
cut-n-paste the important message as part of a bugreport.Signed-off-by: Arjan van de Ven

Patch : http://lkml.org/lkml/2008/7/22/364with what I believe is a better fix than the one referenced
in the regression entry above.These PNP header interfaces try to work in such a way that
you can reference some of them even if PNP is not enabled,
and the compiler was expected to optimize everything away.Which is mostly fine, except that there was one interface
for which there was not provided an inline "NOP" implementation.Once we add that, all of these compile failures cannot handle
any more.pnp: Provide NOP inline implementation of pnp_get_resource() when !PNP

- 8-bit interface mode never worked properly. The only adapter I have
which supports the 8b mode (the Jmicron) had some problems with its
clock wiring and they discovered it only now. We also discovered that
ProHG media is more sensitive to the ordering of initialization
commands.- Make the driver fall back to highest supported mode instead of always
falling back to serial. The driver will attempt the switch to 8b mode
for any new MSPro card, but not all of them support it. Previously,
these new cards ended up in serial mode, which is not the best idea
(they work fine with 4b, after all).- Edit some macros for better conformance to Sony documentation

When suspending the system with atmel_lcdfb enabled, I sometimes see
this:atmel_lcdfb atmel_lcdfb.0: FIFO underflow 0x10
Which can be explained by the fact that we're not stopping the LCD
controller and its DMA engine when suspending, we're just gating the
clocks to them.There's another potential issue which may be harder to trigger but
much more nasty: If we gate the clocks at _just_ the right moment,
e.g. when the DMA engine is doing a bus transaction, we may cause the
DMA engine to violate the system bus protocol and cause a lockup.Avoid these issues by shutting down the LCD controller before entering
suspend (and restarting it when resuming). This prevents the underrun
from happening in the first place, and prevents whatever nastiness is
happening when the bus clock stops in the middle of a DMA transfer.Signed-off-by: Haavard Skinnemoen

If you are on ia64 and you modprobe xpc then modprobe -r xpc, you
immediately get a panic. xpc depends on xp which depends on gru for a
symbol. That symbol is only used when we are running on UV hardware.Currently, the GRU driver detects we are not on UV hardware and does no
initializing. It does not do the same check when unloading. As a result,
the gru driver attempts to tear down stuff that was not setup.This is a simple two-line workaround to get us through this release. Once
2.6.28 is opened, we need to rework the symbols that xp is depending on
from gru so the gru driver can properly fail to load when hardware is not
available.Signed-off-by: Robin Holt

The iterator for_each_zone_zonelist() uses a struct zoneref *z cursor when
scanning zonelists to keep track of where in the zonelist it is. The
zoneref that is returned corresponds to the the next zone that is to be
scanned, not the current one. It was intended to be treated as an opaque
list.When the page allocator is scanning a zonelist, it marks elements in the
zonelist corresponding to zones that are temporarily full. As the
zonelist is being updated, it uses the cursor here;if (NUMA_BUILD)
zlc_mark_zone_full(zonelist, z);This is intended to prevent rescanning in the near future but the zoneref
cursor does not correspond to the zone that has been found to be full.
This is an easy misunderstanding to make so this patch corrects the
problem by changing zoneref cursor to be the current zone being scanned
instead of the next one.Signed-off-by: Mel Gorman

Fixes two DMA bugs in the pxa2xx_spi driver. The first bug is in all
versions of this driver; the second was introduced in the 2.6.20 kernel,
and prevents using the driver with chips like m25p16 flash (which can
issue large DMA reads).1. Zero length transfers are permitted for use to insert timing,
but pxa2xx_spi.c will fail if this is requested in DMA mode.
Fixed by using programmed I/O (PIO) mode for such transfers.2. Transfers larger than 8191 are not permitted in DMA mode. A
test for length rejects all large transfers regardless of DMA
or PIO mode. Worked around by rejecting only large transfers
with DMA mapped buffers, and forcing all other transfers
larger than 8191 to use PIO mode. A rate limited warning is
issued for DMA transfers forced to PIO mode.This patch should apply to all kernels back to and including 2.6.20;
it was test patched against 2.6.20. An additional patch would be
required for older kernels, but those versions are very buggy anyway.Signed-off-by: Ned Forrester

Fixes several chipselect bugs in the pxa2xx_spi driver. These bugs are in
all versions of this driver and prevent using it with chips like m25p16
flash.1. The spi_transfer.cs_change flag is handled too early:
before spi_transfer.delay_usecs applies, thus making the
delay ineffective at holding chip select.2. spi_transfer.delay_usecs is ignored on the last transfer
of a message (likewise not holding chipselect long enough).3. If spi_transfer.cs_change is set on the last transfer, the
chip select is always disabled, instead of the intended
meaning: optionally holding chip select enabled for the
next message.Those first three bugs were fixed with a relocation of delays
and chip select de-assertions.4. If a message has the cs_change flag set on the last transfer,
and had the chip select stayed enabled as requested (see 3,
above), it would not have been disabled if the next message is
for a different chip. Fixed by dropping chip select regardless
of cs_change at end of a message, if there is no next message
or if the next message is for a different chip.This patch should apply to all kernels back to and including 2.6.20;
it was test patched against 2.6.20. An additional patch would be
required for older kernels, but those versions are very buggy anyway.Signed-off-by: Ned Forrester

(http://www.t13.org/Documents/UploadedDocuments/project/d1410r3b-ATA-ATAPI-6.pdf)8.15.29 Word (61:60): Total number of user addressable sectors
This field contains a value that is one greater than the total number
of user addressable sectors (see 6.2). The maximum value that shall
be placed in this field is 0FFFFFFFh.So the driver shouldn't use the value of 0xfffffff for LBA28 request
as this exceeds maximum user addressable sector. The logical maximum
value for LBA28 is 0xffffffe.The obvious fix is to cut "- 1" part, and the patch attached just do
that. I've been using the patched kernel for about a month now, and
the same fix is also floating on the net for some time. So I believe
this fix works reliably.Just FYI, many Windows/Intel platform users also seems to be struck
by this, and HGST has issued a note pointing to Intel ICH8/9 driver."28-bit LBA command is being used to access LBAs 29-bits in length"
