Will Newton 229cc58ba2 mtd_dataflash: fix probing of AT45DB321C chips.
Commit 771999b65f ("[MTD] DataFlash: bugfix,
binary page sizes now handled") broke support for probing AT45DB321C flash
chips.  These chips do not support the "page size" status bit, so if we
match the JEDEC id return early.

Yinghai Lu 2f68891314 x86/agp: tighten check to update amd nb aperture
Impact: fix bug to make agp work with dri

Jeffrey reported that dri does work with 64bit, but doesn't work with
32bit it turns out NB aperture is 32M, aperture on agp is 128M

64bit is using 64M for vaidation for 64 iommu/gart 32bit is only using
32M..., and will not update the nb aperture.

So try to compare nb apterture and agp apterture before leaving not
touch nb aperture.

Darrick J. Wong c15ade6578 lm85: fix the version check that broke adt7468 probing
The verstep check in the lm85 driver fails because the upper nibble of
the version register is 0x7, not 0x6, on the adt7468 chip.  Probing of
all adt7468s was broken by 69fc1feba2
("hwmon: (lm85) Rework the device detection"), and this patch fixes
that.  Also add in a missing i2c_device_id that accidentally got dropped
from the original patch.

Roel Kluin 4750498099 mm: get_nid_for_pfn() returns int
get_nid_for_pfn() returns int

Presumably the (nid < 0) case has never happened.

We do know that it is happening on one system while creating a symlink for
a memory section so it should also happen on the same system if
unregister_mem_sect_under_nodes() were called to remove the same symlink.

The test was actually added in response to a problem with an earlier
version reported by Yasunori Goto where one or more of the leading pages
of a memory section on the 2nd node of one of his systems was
uninitialized because I believe they coincided with a memory hole.

That earlier version did not ignore uninitialized pages and determined
the nid by considering only the 1st page of each memory section.  This
caused the symlink to the 1st memory section on the 2nd node to be
incorrectly created in /sys/devices/system/node/node0 instead of
/sys/devices/system/node/node1.  The problem was fixed by adding the
test to skip over uninitialized pages.

I suspect we have not seen any reports of the non-removal
of a symlink due to the incorrect declaration of the nid
variable in unregister_mem_sect_under_nodes() because
  - systems where a memory section could have an uninitialized
    range of leading pages are probably rare.
  - memory remove is probably not done very frequently on the
    systems that are capable of demonstrating the problem.
  - lingering symlink(s) that should have been removed may
    have simply gone unnoticed.

Johannes Weiner 96fe2ab830 HID: fix waitqueue usage in hiddev
DECLARE_WAITQUEUE doesn't initialize the wait descriptor's task_list
to 'empty' but to zero.

prepare_to_wait() will not enqueue the descriptor to the waitqueue and
finish_wait() will do list_del_init() on a list head that contains
NULL pointers, which oopses.

This was introduced by 079034073 "HID: hiddev cleanup -- handle all
error conditions properly".

The prior code used an unconditional add_to_waitqueue() which didn't
care about the wait descriptor's list head and enqueued the thing
unconditionally.

The new code uses prepare_to_wait() which DOES check the prior list
state, so use DEFINE_WAIT instead.

Chris Leech 55c8bafba5 [SCSI] fcoe: fix handling of pending queue, prevent out of order frames (v3)
In fcoe_check_wait_queue() the queue length could temporarily drop to 0,
before the last frame was successfully sent.  This resulted in out of order
data frames within a single sequence, leading to IO timeout errors.

This builds on the approach from Vasu Dev to only fix the queue management in
fcoe_check_wait_queue, where my first patch added locking to the transmit
path even when the pending queue was not in use.

This patch continues to use fcoe_pending_queue.qlen instead of introducing a
new length counter, but takes precautions to ensure it never drops to 0 before
the final frame in the queue has successfully been passed to the netdev qdisc
layer.  It also includes some cleanup of fcoe_check_wait_queue and removes the
fcoe_insert_wait_queue(_head) wrapper functions.

Vasu Dev c826a31457 [SCSI] fcoe: Out of order tx frames was causing several check condition SCSI status
frames followed by these errors in log.

	[sdp] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK
	[sdp] Sense Key : Aborted Command [current]
	[sdp] Add. Sense: Data phase error

This was causing some test apps to exit due to write failure under heavy
load.

This was due to a race around adding and removing tx frame skb in
fcoe_pending_queue, Chris Leech helped me to find that brief unlocking
period when pulling skb from fcoe_pending_queue in various contexts
(fcoe_watchdog and fcoe_xmit) and then adding skb back into fcoe_pending_queue
up on a failed fcoe_start_io could change skb/tx frame order in
fcoe_pending_queue. Thanks Chris.

This patch allows only single context to pull skb from fcoe_pending_queue
at any time to prevent above described ordering issue/race by use of
fcoe_pending_queue_active flag.

This patch simplified fcoe_watchdog with modified fcoe_check_wait_queue by
use of FCOE_LOW_QUEUE_DEPTH instead previously used several conditionals
to clear and set lp->qfull.

I think FCOE_MAX_QUEUE_DEPTH with FCOE_LOW_QUEUE_DEPTH  will work better
in re/setting lp->qfull and these could be fine tuned for performance.

unneeded/undesirable cast of void*.  There are probably zillions of
instances of this - there always are.

This whole inline function was unnecessary. The FCoE layer knows
that it's data structure is stored in the lport private data, it

This reverts commit e088e4c9cd.

Removing the sysfs interface for p4-clockmod was flagged as a
regression in bug 12826.

Course of action:
 - Find out the remaining causes of overheating, and fix them
   if possible. ACPI should be doing the right thing automatically.
   If it isn't, we need to fix that.
 - mark p4-clockmod ui as deprecated
 - try again with the removal in six months.

It's not really feasible to printk about the deprecation, because
it needs to happen at all the sysfs entry points, which means adding
a lot of strcmp("p4-clockmod".. calls to the core, which.. bleuch.

Robert Love efaf5c085d [SCSI] libfc: check for err when recv and state is incorrect
If we've just created an interface and the an rport is
logging in we may have a request on the wire (say PRLI).
If we destroy the interface, we'll go through each rport
on the disc->rports list and set each rport's state to NONE.
Then the lport will reset the EM. The EM reset will send a
CLOSED event to the prli_resp() handler which will notice
that the state != PRLI. In this case it frees the frame
pointer, decrements the refcount and unlocks the rport.

The problem is that there isn't a frame in this case. It's
just a pointer with an embedded error code. The free causes
an Oops.

This patch moves the error checking to be before the state
checking.

Steve Ma f7db2c150c [SCSI] libfc: exch mgr is freed while lport still retrying sequences
When a sequence cannot be delivered to the target, the local
port will schedule retries, While this process is in progress,
if we destroy the FCoE interface, the fcoe_sw_destroy routine is
entered, and the fc_exch_mgr_free(lp->emp) is called.  Thus
if fc_exch_alloc() is called when retrying the sequence,
the mempool_alloc() will fail to allocate the exchange because
the mempool of the exchange manager has already been released.
This patch is to cancel any pending retry work of the local
port before we start to destroy the interface.

Also, when resetting the local port, we should also stop the
scheduled pending retries.

Chris Leech 6755db1cd4 [SCSI] libfc: rport retry on LS_RJT from certain ELS
This allows any rport ELS to retry on LS_RJT.

The rport error handling would only retry on resource allocation failures
and exchange timeouts.  I have a target that will occasionally reject PLOGI
when we do a quick LOGO/PLOGI.  When a critical ELS was rejected, libfc would
fail silently leaving the rport in a dead state.

The retry count and delay are managed by fc_rport_error_retry.  If the retry
count is exceeded fc_rport_error will be called.  When retrying is not the
correct course of action, fc_rport_error can be called directly.

Vasu Dev bc0e17f691 [SCSI] libfc, fcoe: fixed locking issues with lport->lp_mutex around lport->link_status
The fcoe_xmit could call fc_pause in case the pending skb queue len is larger
than FCOE_MAX_QUEUE_DEPTH, the fc_pause was trying to grab lport->lp_muex to
change lport->link_status and that had these issues :-

1. The fcoe_xmit was getting called with bh disabled, thus causing
"BUG: scheduling while atomic" when grabbing lport->lp_muex with bh disabled.

2. fc_linkup and fc_linkdown function calls lport_enter function with
lport->lp_mutex held and these enter function in turn calls fcoe_xmit to send
lport related FC frame, e.g. fc_linkup => fc_lport_enter_flogi to send flogi
req. In this case grabbing the same lport->lp_mutex again in fc_puase from
fcoe_xmit would cause deadlock.

The lport->lp_mutex was used for setting FC_PAUSE in fcoe_xmit path but
FC_PAUSE bit was not used anywhere beside just setting and clear this
bit in lport->link_status, instead used a separate field qfull in fc_lport
to eliminate need for lport->lp_mutex to track pending queue full condition
and in turn avoid above described two locking issues.

Also added check for lp->qfull in fc_fcp_lport_queue_ready to trigger
SCSI_MLQUEUE_HOST_BUSY when lp->qfull is set to prevent more scsi-ml cmds
while lp->qfull is set.

This patch eliminated FC_LINK_UP and FC_PAUSE and instead used dedicated
fields in fc_lport for this, this simplified all related conditional
code.

Also removed fc_pause and fc_unpause functions and instead used newly added
lport->qfull directly in fcoe.

orion5x_wdt no longer compiled after the changes in commit
ebe35aff88 ("Orion: prepare for

The tick rate define (ORION5X_TCLK) was removed in favor of a runtime
detection. The quick fix is to add the define in the watchdog driver.
The fix is not correct for all supported orion5x platforms, but since
the supported platforms right now are 133 Mhz and 166 Mhz, it won't
be _that_ far off. ;-) A fix that uses the runtime-determined timer
tick rate will be applied later.

Robert Hancock 968e594afd libata: Don't trust current capacity values in identify words 57-58
Hanno Böck reported a problem where an old Conner CP30254 240MB hard drive
was reported as 1.1TB in capacity by libata:

http://lkml.org/lkml/2009/2/13/134

This was caused by libata trusting the drive's reported current capacity in
sectors in identify words 57 and 58 if the drive does not support LBA and the
current CHS translation values appear valid. Unfortunately it seems older
ATA specs were vague about what this field should contain and a number of drives
used values with wrong byte order or that were totally bogus. There's no
unique information that it conveys and so we can just calculate the number
of sectors from the reported current CHS values.

While we're at it, clean up this function to use named constants for the
identify word values.

Tejun Heo d6515e6ff4 libata: make sure port is thawed when skipping resets
When SCR access is available and the link is offline, softreset is
skipped as it only wastes time and some controllers don't respond very
well.  However, the skip path forgot to thaw the port, which not only
blocks further event notification from the port but also causes
repeated EH invocations on the same event on drivers which rely on
->thaw() to clear events if the IRQ is shared with another device or
port.

This problem has always been there but is uncovered by recent sata_nv
nf2/3 change which dropped hardreset support while maintaining SCR
access.  nf2/3 doesn't clear hotplug event mask from the interrupt
handler but relies on ->thaw() to clear them.  When the hardreset was
there, the reset action was never skipped and the port was always
thawed but, with the hardreset gone, ->prereset() determines that
there's no need for softreset and both ->softreset() and ->thaw() are
skipped.  This leads to stuck hotplug event in the IRQ status register
triggering hotplug event whenever IRQ is delieverd on the same IRQ.
As the controller shares the same IRQ for both ports, this happens on
every IO if one port is occpupied and the other isn't.

This patch fixes the problem by making sure that the port is thawed on
reset-skip path.

bko#11615 reports this problem.

dma_unmap_sg(),which is the misuse of dma_unmap_sg().

DMA-mapping.txt says:

To unmap a scatterlist, just call:

	pci_unmap_sg(pdev, sglist, nents, direction);

Again, make sure DMA activity has already finished.

PLEASE NOTE:  The 'nents' argument to the pci_unmap_sg call must be
              the _same_ one you passed into the pci_map_sg call,
	      it should _NOT_ be the 'count' value _returned_ from the
              pci_map_sg call.

Kris Shannon a1a15ac5f9 Fix kernel NULL pointer dereference in xen-blkfront
When booting Xen Dom0 on a pre-release 3.2.1 hypervisor the system Oopses on a
"Unable to handle kernel NULL pointer dereference" in xenwatch.

From the backtrace it looks like backend_changed is calling bdget_disk
with a NULL pointer.  Checking for NULL and returning ENODEV instead
allows the kernel to boot.

Commit 6833c043f9 introduced the phy
auto-powerdown capability.  While the APD feature only works for 5761
and 5784 asic revisions, the (harmless portion of the) code was applied
to all 5705 and newer devices.  However, the 5906 phy departs from the
usual design.  This commit was interfering with the 5906's ability to
negotiate link against some switches.  This patch corrects the problem.

The following patch enables SMC911x support to work on the OMAP LDP
board.  Although the SMC911x driver will eventually be obsoleted, the

Rather than risk destablising smsc911x, this simpler patch is preferred
to allow the network interface to work.

This is done by
1) Wake up lock waiters when we close the master file descriptor.
   Not when the master structure is removed, since the latter
   requires the waiters themselves to release the refcount on the
   master structure -> Deadlock.
2) Send a SIGTERM to all clients waiting for the lock.
   Normally these clients will get a SIGPIPE when the X server dies,
   but clients may also spin trying to grab the DRM lock, without
   getting any sort of notification.

Bjørn Mork cac477e8f1 cdc_ether: add usb id for Ericsson F3507g
The Ericsson F3507g wireless broadband module provides a CDC Ethernet
compliant interface, but identifies it as a "Mobile Direct Line" CDC
subclass, thereby preventing the CDC Ethernet class driver from picking
it up.  This patch adds the device id to cdc_ether.c as a workaround.

Ericsson has provided a "class" driver for this device:
http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094
But closer inspection of that driver reveals that it adds little more
than duplication of code from cdc_ether.c.  See also

Ivan Vecera 6709fe9a27 r8169: read MAC address from EEPROM on init (2nd attempt)
This is 2nd attempt to implement the initialization/reading of MAC address
from EEPROM. The first used PCI's VPD and there were some problems, some
devices are not able to read EEPROM content by VPD. The 2nd one uses direct
access to EEPROM through bit-banging interface and my testing results seem
to be much better.

I tested 5 systems each with different Realtek NICs and I didn't find any
problem. AFAIK Francois's NICs also works fine.

Original description:
This fixes the problem when MAC address is set by ifconfig or by
ip link commands and this address is stored in the device after
reboot. The power-off is needed to get right MAC address.
This is problem when Xen daemon is running because it renames the device
name from ethX to pethX and sets its MAC address to FE:FF:FF:FF:FF:FF.
After reboot the device is still using FE:FF:FF:FF:FF:FF.

Feeding 32-bit length cast down to 'u16' to min() to calculate the FIFO

transfer sizes over 64 KB.

Similarly, although data transfer size shouldn't exceed 65535 bytes for

with possibly oversized buffer will not hurt either...

For some strange reason the host side musb_giveback() decides
that it's always got an IN transfer when the hardware endpoint

may also cause unneeded reloading of RX endpoint registers.

The musb_h_disable() routine can oops in some cases:

 - It's not safe to read hep->hcpriv outside musb->lock,
   since it gets changed on completion IRQ paths.

 - The list iterators aren't safe to use in that way;
   just remove the first element while !list_empty(),
   so deletions on other code paths can't make trouble.

We need two "scrub the list" loops because only one branch
should touch hardware and advance the schedule.

The urb_dequeue() method forgets to unlink 'struct musb_qh' from the
control or bulk schedules when the URB being cancelled is the only
one queued to its endpoint.  That will cause musb_advance_schedule()
to block once it reaches 'struct musb_qh' with now empty URB list, so
URBs queued for other endpoints after the one being dequeued will not
be served.

Fix by unlinking the QH from the list except when it's already being
handled (typically by musb_giveback).  Since a QH with an empty URB
list is now supposed to be freed, do that.  And remove a now-useless
check from musb_advance_schedule().

Now that the musb build fixes for DaVinci got merged (RC3?), kick in
the other bits needed to get it finally *working* in mainline:

 - Use clk_enable()/clk_disable() ... the "always enable USB clocks"
   code this originally relied on has since been removed.

 - Initialize the USB device only after the relevant I2C GPIOs are
   available, so the host side can properly enable VBUS.

 - Tweak init sequencing to cope with mainline's relatively late init
   of the I2C system bus for power switches, transceivers, and so on.

Sanity tested on DM6664 EVM for host and peripheral modes; that system
won't boot with CONFIG_PM enabled, so OTG can't yet be tested.  Also
verified on OMAP3.

Alan Stern 67f5a4ba97 USB: usb_get_string should check the descriptor type
This patch (as1218) fixes a problem with a radio-control joystick used
in the "walkera 4#3" helicopter.  This device responds to the initial
Get-String-Descriptor request for string 0 (which is really the list
of supported languages) by sending its config descriptor!  The
usb_get_string() routine needs to check whether it got the right
type of descriptor.

Oddly enough, this sort of check is already present in
usb_get_descriptor().  The patch changes the error code from -EPROTO
to -ENODATA, because -EPROTO shows up in so many other contexts to
indicate a hardware failure rather than a firmware error.

This patch (as1219) adds the IGNORE_RESIDUE flag to the unusual_devs

usually gets the residue correct, there is one command crucial to the
operation of CD and DVD drives which it messes up.

Karsten Wiese 9aa09d2f8f USB: EHCI: slow down ITD reuse
Currently ITDs are immediately recycled whenever their URB completes.
However, EHCI hardware can sometimes remember some ITD state.  This
means that when the ITD is reused before end-of-frame it may sometimes
cause the hardware to reference bogus state.

This patch defers reusing such ITDs by moving them into a new ehci member
cached_itd_list. ITDs resting in cached_itd_list are moved back into their
stream's free_list once scan_periodic() detects that the active frame has
elapsed.

This makes the snd_usb_us122l driver (in kernel since .28) work right
when it's hooked up through EHCI.

2) This fixes a bug where the device will come up with the enable-bit

With (some) Technisat cards you cannot run multiple DVB applications
in parallel and switch the channel at the same time.

There seems to be a problem on the interfaces or even inside the flexcop-device
that can't handle interruption on the streaming interface.

This patch adds a watchdog to check whether data is supposed to come in
(streaming PIDs are requested) and if no data is seen within 400ms (default) it
resets the streaming/pid-filtering hardware.

This patch is urgently needed to support the rev 2.8 of the hardware and solves
problem occassionally seen on older hardware.

Herbert Xu a760a6656e crypto: api - Fix module load deadlock with fallback algorithms
With the mandatory algorithm testing at registration, we have
now created a deadlock with algorithms requiring fallbacks.
This can happen if the module containing the algorithm requiring
fallback is loaded first, without the fallback module being loaded
first.  The system will then try to test the new algorithm, find
that it needs to load a fallback, and then try to load that.

As both algorithms share the same module alias, it can attempt
to load the original algorithm again and block indefinitely.

As algorithms requiring fallbacks are a special case, we can fix
this by giving them a different module alias than the rest.  Then
it's just a matter of using the right aliases according to what
algorithms we're trying to find.

For some reason, sata_mv doesn't clear interrupt status during init
when it's running on an SoC host adapter.  If the bootloader has
touched the SATA controller before starting Linux, Linux can end up
enabling the SATA interrupt with events pending, which will cause the
interrupt to be marked as spurious and then be disabled, which then
breaks all further accesses to the controller.

This patch makes the SoC path clear interrupt status on init like in
the non-SoC case.

Ondrej Zary 7ba07d16bd pata_it821x: resume from hibernation fails with RAID volume
Hibernation didn't work for me since I started to use IT8212 controller.
I did some debugging (booting with no_console_suspend init=/bin/sh).

Found that resume fails (2.6.28) with "serial number mismatch 'some
garbage' != 'some other garbage'" and "revalidation failed" messages.
That's because the controller firmware fills different serial number in
the IDENTIFY every boot.

The patch below fixes the resume simply clearing the serial number.  The
proper fix would be probably to fill in the serial number of the RAID
volume instead.  I assume that there must be something like that stored on
the drives but I don't know where.

Fix resume on pata_it821x RAID volume by clearing the serial number in
IDENTIFY data, which is otherwise different on each boot.

Roel Kluin f76bee16fc atiixp: fix missing parentheses
Fix missing parentheses so PIO/DMA timings for master device on the
second channel are programmed correctly (IOW "8 0 24 16" offset values
should be used instead of the current "8 0 16 16").

[ The bug went unnoticed because after PIO/DMA timings get programmed
  incorrectly for the third device they are overwritten with timings
  for the fourth device and since BIOS should also program timings for
  the third device everything should work fine until suspend/resume
  cycle or user requested transfer mode changes. ]

David Fries 0af80c04e2 ide: ide.c 'clear' fix, update "ide=nodma" documentation
Documentation/kernel-parameters.txt
- ide=nodma is no longer valid.

drivers/ide/Kconfig
- The module is ide-core.ko not ide.

drivers/ide/ide.c
- It took me a while to figure out what the arguments %d.%d:%d to nodma
  module parameter ment, so I added a comment to each.
- Added a comment to each of the sscanf lines.
- There is a bug, if j is 0 it would previously clear all the other bits
  except the current device, changed in three different places.
  mask &= (1 << i) should be mask &= ~(1 << i).

Fenghua Yu 6aa03ab069 Fix iwlan DMA mapping direction
When iwlan runs on IOMMU, IOMMU generates a lot of PTE write faults
because PTE write bit is not set on some of PTE's.  This is because
iwlan driver calls DMA mapping with PCI_DMA_TODEVICE which is read only
in mapping PTE.  But iwlan device actually writes to the mapped page to
update its contents.  This issue is not exposed in swiotlb.  But VT-d
hardware can capture this fault and stop the fault transaction.

The following patch fixes the issue.
