commit ac8672ea922bde59acf50eaa1eaa1640a6395fd2 upstream.
ata_tf_read_block() has off-by-one error when converting CHS address
to LBA. The bug isn't very visible because ata_tf_read_block() is
used only when generating sense data for a failed RW command and CHS
addressing isn't used too often these days.
This problem was spotted by Atsushi Nemoto.

commit ec57935837a78f9661125b08a5d08b697568e040 upstream.
When probing the device in tpm_tis_init the call request_locality
uses timeout_a, which wasn't being initalized until after
request_locality. This results in request_locality falsely timing
out if the chip is still starting. Move the initialization to before
request_locality.
This probably only matters for embedded cases (ie mine), a BIOS likely
gets the TPM into a state where this code path isn't necessary.

commit bc00351edd5c1b84d48c3fdca740fedfce4ae6ce upstream.
A workaround for flash memory I/O errors when the PS3 internal
hard disk has not been formatted for OtherOS use.
This error condition mainly effects 'Live CD' users who have not
formatted the PS3's internal hard disk for OtherOS.
Fixes errors similar to these when using the ps3-flash-util
or ps3-boot-game-os programs:
ps3flash read failed 0x2050000
os_area_header_read: read error: os_area_header: Input/output error
main:627: os_area_read_hp error.

[ Upstream commit 6ff9c2e7fa8ca63a575792534b63c5092099c286 ]
E100 places it's RX packet descriptors inside skb->data and uses them
with bidirectional streaming DMA mapping. Data in descriptors is
accessed simultaneously by the chip (writing status and size when
a packet is received) and CPU (reading to check if the packet was
received). This isn't a valid usage of PCI DMA API, which requires use
of the coherent (consistent) memory for such purpose. Unfortunately e100
chips working in "simplified" RX mode have to store received data
directly after the descriptor. Fixing the driver to conform to the API
would require using unsupported "flexible" RX mode or receiving data
into a coherent memory and using CPU to copy it to network buffers.
This patch, while not yet making the driver conform to the PCI DMA API,
allows it to work correctly on X86 with swiotlb (while not breaking
other architectures).

commit 96bcc722c47d07b6fd05c9d0cb3ab8ea5574c5b1 upstream
[SCSI] sr: report more accurate drive status after closing the tray.
So, what's happening here is that the drive is reporting a sense of
2/4/1 ("logical unit is becoming ready") from sr_test_unit_ready(), and
then we ask for the media event notification before checking that result
at all. The check_media_event_descriptor() call isn't getting a check
condition, but it's also reporting that the tray is closed and that
there's no media. In actuality it doesn't yet know if there's media or
not, but there's no way to express that in the media event status field.
My current thought is that if it told us the device isn't yet ready, we
should return that immediately, since there's nothing that'll tell us
any more data than that reliably:

commit 05ad709d04799125ed85dd816fdb558258102172 upstream
parport: quickfix the proc registration bug
Ideally we should have a directory of drivers and a link to the 'active'
driver. For now just show the first device which is effectively the existing
semantics without a warning.
This is an update on the original buggy patch that I then forgot to
resubmit. Confusingly it was proposed by Red Hat, written by Etched Pixels
fixed and submitted by Intel ...

commit 18753ebc8a98efe0e8ff6167afb31cef220c8e50 upstream.
access_ok() checks must be done on every part of the userspace structure
that is accessed. If access_ok() on one part of the struct succeeded, it
does not imply it will succeed on other parts of the struct. (Does
depend on the architecture implementation of access_ok()).
This changes the __get_user() users to first check access_ok() on the
data structure.

commit 7a777919bbeec3eac1d7904a728a60e9c2bb9c67 upstream.
Requests to get max LUN, for certain USB storage devices, require a
longer timeout before a correct reply is returned. This happens for a
Realtek USB Card Reader (0bda:0152), which has a max LUN of 3 but is set
to 0, thus losing functionality, because of the timeout occurring too
quickly.
Raising the timeout value fixes the issue and might help other devices
to return a correct max LUN value as well.

commit 550e7fd8afb7664ae7cedb398c407694e2bf7d3c upstream.
Currently, the ThinkPad-ACPI bay and dock drivers are completely
broken, and cause a NULL pointer derreference in kernel mode (and,
therefore, an OOPS) when they try to issue events (i.e. on dock,
undock, bay ejection, etc).
OTOH, the standard ACPI dock driver can handle the hotplug bays and
docks of the ThinkPads just fine (including batteries) as of 2.6.27.
In fact, it does a much better job of it than thinkpad-acpi ever did.
It is just not worth the hassle to find a way to fix this crap without
breaking the (deprecated) thinkpad-acpi dock/bay ABI. This is old,
deprecated code that sees little testing or use.
As a quick fix suitable for -stable backports, mark the thinkpad-acpi
bay and dock subdrivers as BROKEN in Kconfig. The dead code will be
removed by a later patch.
This fixes bugzilla #13669, and should be applied to 2.6.27 and later.

commit 5381837f125cc62ad703fbcdfcd7566fc81fd404 upstream.
There's a hotplug problem in the way libsas allocates ports: it loops over the
available ports first trying to add to an existing for a wide port and
otherwise allocating the next free port. This scheme only works if the port
array is packed from zero, which fails if a port gets hot unplugged and the
array becomes sparse. In that case, a new port is formed even if there's a
wide port it should be part of. Fix this by creating two loops over all the
ports: the first to see if the phy should be part of a wide port and the
second to form a new port in an empty port slot.

The issue was, that the locking code in mkiss was assuming it was only
ever being called in process or bh context. Fixed by converting the
involved locking code to use irq-safe locks.
Review of other networking line disciplines shows that 6pack, both sync
and async PPP and STRIP have similar issues. The ppp_async one is the
most interesting one as it sorts out half of the issue as far back as

[ Upstream commit f11a377b3f4e897d11f0e8d1fc688667e2f19708 ]
The 8169 chip only generates MSI interrupts when all enabled event
sources are quiescent and one or more sources transition to active. If
not all of the active events are acknowledged, or a new event becomes
active while the existing ones are cleared in the handler, we will not
see a new interrupt.
The current interrupt handler masks off the Rx and Tx events once the
NAPI handler has been scheduled, which opens a race window in which we
can get another Rx or Tx event and never ACK'ing it, stopping all
activity until the link is reset (ifconfig down/up). Fix this by always
ACK'ing all event sources, and loop in the handler until we have all
sources quiescent.

commit e705cee427e319665969ef7ac664f3612dec8899 upstream.
This patch adds DMI information to automatically load the correct
layout for the Maxdata Pro 7000X/DX notebook models. Such notebooks
are clones of Fujitsu Amilo V2000, the hook for the v2000 is being
used and I have tested that perfectly works.
The immediate result of integrating this patch is that the five
special buttons will work on these specific notebook models and that
the RF killswitch will not be activated after suspend. This patch
definitively obsoletes the fsam7400 module which I was still needing
to enable wifi and to fix the RF killswitch suspend problem; in the
current 2.6.30 kernel it is necessary to load the wistron_btns module
with options 'force=1 keymap=1557/MS2141', which was not anyway a
complete workaround.

commit 19bde778c1fd2574cc020a618d7d576f260271ca upstream.
6328a57401dc5f5cf9931738eb7268fcd8058c49
"Enable PNPACPI _PSx Support, v3"
added a call to acpi_bus_set_power(handle, ACPI_STATE_D3)
to pnpacpi_disable_resource() before the existing call
to evaluate _DIS on the device.
This caused suspend to fail on the system in
http://bugzilla.kernel.org/show_bug.cgi?id=13243
because the sanity check to verify we entered _PS3
failed on the serial port.
As a work-around, that sanity check can be disabled
system-wide with "acpi.power_nocheck=1"
Or perhaps we should just shrug off the _PS3 failure
and carry on with _DIS like we used to -- which is
what this patch does.

commit 6328a57401dc5f5cf9931738eb7268fcd8058c49 upstream.
(This is an update to the patch presented earlier in
http://lkml.org/lkml/2008/12/8/284, with new error handling.)
This patch sets the power of PnP ACPI devices to D0 when they
are activated and to D3 when they are disabled. The latter is
in correspondence with the ACPI 3.0 specification, whereas the
former is added in order to be able to power up a device after
it has been previously disabled (or when booting up a system).
(As a consequence, the patch makes the PnP ACPI code more ACPI
compliant.)
Section 6.2.2 of the ACPI Specification (at least versions 1.0b
and 3.0a) states: "Prior to running this control method [_DIS],
the OS[PM] will have already put the device in the D3 state."
Unfortunately, there is no clear statement as to when to put
a device in the D0 state. :-( Therefore, the patch executes the
method calls as _PS3/_DIS and _SRS/_PS0. What is clear: "If the
device is disabled, _SRS enables the device at the specified
resources." (From the ACPI 3.0a Specification.)
The patch fixes a problem with some IBM ThinkPads (at least the
600E and the 600X) where the serial ports have a dedicated
power source that needs to be brought up before the serial port
can be used. Without this patch, the serial port is enabled
but has no power. (In the past, the tpctl utility had to be
utilized to turn on the power, but support for this feature
stopped with version 5.9 as it did not support the more recent
kernel versions.)
The error handlers that handle any errors that can occur during
the power up/power down phases return the error codes to the
caller directly. Comments welcome! :-)
No regressions were observed on hardware that does not require
this patch.
The patch is applied against 2.6.27.x.

commit 4e19f220d4e84f5728cb7edde36352ab425cfba4 upstream.
The reworked Ethernet gadget has an RNDIS interop problem when used
with the CDC subset driver ... e.g. on PXA 2xx and 3xx hardware,
which currently has a hard time talking to MS-Windows hosts.
The issue is that Microsoft requires USB_CLASS_COMM. Fix by tweaking
the CDC subset driver to not switch to USB_CLASS_VENDOR_SPEC if RNDIS
is used in some other device configuration.

commit 9180135bc80ab11199d482b6111e23f74d65af4a upstream.
This patch (as1262) fixes a bug in usbfs: It refuses to accept
zero-length transfers, and it insists that the buffer pointer be valid
even if there is no data being transferred.
The patch also consolidates a bunch of repetitive access_ok() checks
into a single check, which incidentally fixes the lack of such a check
for Isochronous URBs.

commit d3a263a8168f78874254ea9da9595cfb0f3e96d7 upstream.
I recently discovered on my zalon that if the attachment fails because
of a bus misconfiguration (I scrapped my HVD array, so the card is now
unterminated) then the system oopses. The reason is that if
ncr_attach() returns NULL (signalling failure) that NULL is passed by
the goto failed straight into ncr_detach() which oopses.
The fix is just to return -ENODEV in this case.

commit 3730793d457fed79a6d49bae72996d458c8e4f2d upstream.
There's some odd bug in gcc-4.2 where it miscompiles a simple loop whent
he loop counter is of type 'unsigned char' and it should count to 128.
The compiler will incorrectly decide that a trivial loop like this:
unsigned char i, ...
for (i = 0; i < 128; i++) {
..
is endless, and will compile it to a single instruction that just
branches to itself.
This was triggered by the addition of '-fno-strict-overflow', and we
could play games with compiler versions and go back to '-fwrapv'
instead, but the trivial way to avoid it is to just make the loop
induction variable be an 'int' instead.
Thanks to Krzysztof Oledzki for reporting and testing and to Troy Moure
for digging through assembler differences and finding it.

commit 1f8ae0a21d83f43006d7f6d2862e921dbf2eeddd upstream.
The original patch was submitted last year but wasn't discussed or applied
because of missing maintainer's CCs. I only fixed some formatting errors,
but as I saw tulip is very badly formatted and needs further work.
Original description:
This patch fixes MTU problem, which occurs when using 802.1q VLANs. We
should allow receiving frames of up to 1518 bytes in length, instead of
1514.
Based on patch written by Ben McKeegan for 2.4.x kernels. It is archived
at http://www.candelatech.com/~greear/vlan/howto.html#tulip
I've adjusted a few things to make it apply on 2.6.x kernels.
Tested on D-Link DFE-570TX quad-fastethernet card.

commit a15a519ed6e5e644f5a33c213c00b0c1d3cfe683 upstream.
This fixes kernel.org bug #13584. The IOVA code attempted to optimise
the insertion of new ranges into the rbtree, with the unfortunate result
that some ranges just didn't get inserted into the tree at all. Then
those ranges would be handed out more than once, and things kind of go
downhill from there.
