Linus Torvalds 32d687cad3 Merge branch 'fixes-for-3.6' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull DMA-mapping fixes from Marek Szyprowski:
 "Another set of fixes for ARM dma-mapping subsystem.

  Commit e9da6e9905 replaced custom consistent buffer remapping code
  with generic vmalloc areas.  It however introduced some regressions
  caused by limited support for allocations in atomic context.  This
  series contains fixes for those regressions.

  For some subplatforms the default, pre-allocated pool for atomic
  allocations turned out to be too small, so a function for setting its
  size has been added.

  Another set of patches adds support for atomic allocations to
  IOMMU-aware DMA-mapping implementation.

  The last part of this pull request contains two fixes for Contiguous
  Memory Allocator, which relax too strict requirements."

Linus Torvalds bf71d0e18e Bug-fixes:
* Fix for TLB flushing introduced in v3.6
  * Fix Xen-SWIOTLB not using proper DMA mask - device had 64bit but
    in a 32-bit kernel we need to allocate for coherent pages from a
    32-bit pool.
  * When trying to re-use P2M nodes we had a one-off error and triggered
    a BUG_ON check with specific CONFIG_ option.
  * When doing FLR in Xen-PCI-backend we would first do FLR then save the
    PCI configuration space. We needed to do it the other way around.

Mauro Carvalho Chehab 1daae517b3 [media] move i2c files into drivers/media/i2c
Based on a patch from Sylvester Nawrocki

This fixes regression introduced with commmit cb7a01ac32,
"[media] move i2c files into drivers/media/i2c".

The linked order affect what drivers will be initialized first, when
they're built-in at Kernel. While there are macros that allow changing
the init order, like subsys_initcall(), late_initcall() & friends,
when all drivers  linked belong to the same subsystem, it is easier
to change the order at the Makefile.

All I2C modules must be linked before any drivers that actually use it,
in order to ensure proper module initialization order.

Also, the core drivers should be initialized before the drivers that use
them.

This patch reorders the drivers init, in order to fulfill the above
requirements.

Konrad Rzeszutek Wilk 80ba77dfbc xen/pciback: Fix proper FLR steps.
When we do FLR and save PCI config we did it in the wrong order.
The end result was that if a PCI device was unbind from
its driver, then binded to xen-pciback, and then back to its
driver we would get:

> lspci -s 04:00.0
04:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection

e1000e: probe of 0000:04:00.0 failed with error -2

This fixes it by first saving the PCI configuration space, then
doing the FLR.

Ronny Hegewald b5031ed1be xen: Use correct masking in xen_swiotlb_alloc_coherent.
When running 32-bit pvops-dom0 and a driver tries to allocate a coherent
DMA-memory the xen swiotlb-implementation returned memory beyond 4GB.

The underlaying reason is that if the supplied driver passes in a
DMA_BIT_MASK(64) ( hwdev->coherent_dma_mask is set to 0xffffffffffffffff)
our dma_mask will be u64 set to 0xffffffffffffffff even if we set it to
DMA_BIT_MASK(32) previously. Meaning we do not reset the upper bits.
By using the dma_alloc_coherent_mask function - it does the proper casting
and we get 0xfffffffff.

This caused not working sound on a system with 4 GB and a 64-bit
compatible sound-card with sets the DMA-mask to 64bit.

On bare-metal and the forward-ported xen-dom0 patches from OpenSuse a coherent
DMA-memory is always allocated inside the 32-bit address-range by calling
dma_alloc_coherent_mask.

This patch adds the same functionality to xen swiotlb and is a rebase of the
original patch from Ronny Hegewald which never got upstream b/c the
underlaying reason was not understood until now.

The original email with the original patch is in:
http://old-list-archives.xen.org/archives/html/xen-devel/2010-02/msg00038.html
the original thread from where the discussion started is in:

Paul Walmsley 75b53aee2f mmc: omap: fix broken PIO mode
After commit 26b88520b8 ("mmc:
omap_hsmmc: remove private DMA API implementation"), the Nokia N800
here stopped booting:

[    2.086181] Waiting for root device /dev/mmcblk0p1...
[    2.324066] Unhandled fault: imprecise external abort (0x406) at 0x00000000
[    2.331451] Internal error: : 406 [#1] ARM

[    2.348602] LR is at trace_hardirqs_on_caller+0x15c/0x1b0

...

This turned out to be due to memory corruption caused by long-broken
PIO code in drivers/mmc/host/omap.c.  (Previously, this driver had
been using DMA; but the above commit caused the MMC driver to fall
back to PIO mode with an unmodified Kconfig.)

The PIO code, added with the rest of the driver in commit
730c9b7e66 ("[MMC] Add OMAP MMC host
driver"), confused bytes with 16-bit words.  This bug caused memory
located after the PIO transfer buffer to be corrupted with transfers
larger than 32 bytes.  The driver also did not increment the buffer
pointer after the transfer occurred.  This bug resulted in data
corruption during any transfer larger than 64 bytes.

Ian Chen 3550ccdb9d mmc: card: Skip secure erase on MoviNAND; causes unrecoverable corruption.
For several MoviNAND eMMC parts, there are known issues with secure
erase and secure trim.  For these specific MoviNAND devices, we skip
these operations.

Specifically, there is a bug in the eMMC firmware that causes
unrecoverable corruption when the MMC is erased with MMC_CAP_ERASE
enabled.

Doug Anderson 9623b5b919 mmc: dw_mmc: Disable low power mode if SDIO interrupts are used
The documentation for the dw_mmc part says that the low power
mode should normally only be set for MMC and SD memory and should
be turned off for SDIO cards that need interrupts detected.

The best place I could find to do this is when the SDIO interrupt
was first enabled.  I rely on the fact that dw_mci_setup_bus()
will be called when it's time to reenable.

Seungwon Jeon e74f3a9c99 mmc: dw_mmc: fix error handling in PIO mode
Data transfer will be continued until all the bytes are transmitted,
even if data crc error occurs during a multiple-block data transfer.
This means RXDR/TXDR interrupts will occurs until data transfer is
terminated. Early setting of host->sg to NULL prevents going into
xxx_data_pio functions, hence permanent unhandled RXDR/TXDR interrupts
occurs. And checking error interrupt status in the xxx_data_pio functions
is no need because dw_mci_interrupt does do the same. This patch also
removes it.

Datasheet of SYNOPSYS mentions that DTO(Data Transfer Over) interrupt
will be raised even if some error interrupts, however it is actually
found that DTO does not occur. SYNOPSYS has confirmed this issue.
Current implementation defers the call of tasklet_schedule until DTO
when the error interrupts is happened. This patch fixes error handling.

Seungwon Jeon 182c908159 mmc: dw_mmc: amend using error interrupt status
RINTSTS status includes masked interrupts as well as unmasked.
data_status and cmd_status are set by value of RINTSTS in interrupt handler
and tasklet finally uses it to decide whether error is happened or not.
In addition, MINTSTS status is used for setting data_status in PIO.
Masked error interrupt will not be handled and that status can be considered
non-error case.

Even if the datasheet says that the not busy flag has to be used only
for write operations, it's false except for version lesser than v2xx.

Not waiting on the not busy flag for read operations can cause the
controller to hang-up during the initialization of some SD cards
with DMA after the first CMD6 -- the next command is sent too early.

Artem Bityutskiy 78b495c39a UBI: fix a horrible memory deallocation bug
UBI was mistakingly using 'kfree()' instead of 'kmem_cache_free()' when
freeing "attach eraseblock" structures in vtbl.c. Thankfully, this happened
only when we were doing auto-format, so many systems were unaffected. However,
there are still many users affected.

It is strange, but the system did not crash and nothing bad happened when
the SLUB memory allocator was used. However, in case of SLOB we observed an
crash right away.

This problem was introduced in 2.6.39 by commit
"6c1e875 UBI: add slab cache for ubi_scan_leb objects"

A note for stable trees:
  Because variable were renamed, this won't cleanly apply to older kernels.
  Changing names like this should help:
	1. ai -> si
	2. aeb_slab_cache -> seb_slab_cache
	3. new_aeb -> new_seb

Bruce Allan d821a4c4d1 e1000e: DoS while TSO enabled caused by link partner with small MSS
With a low enough MSS on the link partner and TSO enabled locally, the
networking stack can periodically send a very large (e.g.  64KB) TCP
message for which the driver will attempt to use more Tx descriptors than
are available by default in the Tx ring.  This is due to a workaround in
the code that imposes a limit of only 4 MSS-sized segments per descriptor
which appears to be a carry-over from the older e1000 driver and may be
applicable only to some older PCI or PCIx parts which are not supported in
e1000e.  When the driver gets a message that is too large to fit across the
configured number of Tx descriptors, it stops the upper stack from queueing
any more and gets stuck in this state.  After a timeout, the upper stack
assumes the adapter is hung and calls the driver to reset it.

Remove the unnecessary limitation of using up to only 4 MSS-sized segments
per Tx descriptor, and put in a hard failure test to catch when attempting
to check for message sizes larger than would fit in the whole Tx ring.
Refactor the remaining logic that limits the size of data per Tx descriptor
from a seemingly arbitrary 8KB to a limit based on the dynamic size of the
Tx packet buffer as described in the hardware specification.

Also, fix the logic in the check for space in the Tx ring for the next
largest possible packet after the current one has been successfully queued
for transmit, and use the appropriate defines for default ring sizes in
e1000_probe instead of magic values.

This issue goes back to the introduction of e1000e in 2.6.24 when it was
split off from e1000.

I'm slightly concerned by the "only in exceptional circumstances"
comment on __pskb_pull_tail but the structure of an skb just created
by netfront shouldn't hit any of the especially slow cases.

This approach still does slightly more work than the old way, since if
we pull up the entire first frag we now have to shuffle everything
down where before we just received into the right place in the first
place.

Forest Bond 4a68a74ba0 gma500: Consider CRTC initially active.
[this one ideally should make 3.6 - it fixes the very annoying mode setting bug]

This causes the pipe to be forced off prior to initial mode set, which
roughly mirrors the behavior of the i915 driver.  It fixes initial mode
setting on my Intel DN2800MT (Cedarview) board.  Without it, mode
setting triggers an out-of-range error from the monitor for most modes,
but only on initial configuration (i.e. they can be configured
successfully from userspace after that).

Against -net.

In the patch "netpoll: re-enable irq in poll_napi()", I tried to

by reenabling IRQ before calling ->poll, but it seems more
problems are introduced after that patch:

http://ozlabs.org/~akpm/stuff/IMG_20120824_122054.jpg
http://marc.info/?l=linux-netdev&m=134563282530588&w=2

So it is safe to fix be2net driver code directly.

This patch reverts the offending commit and fixes be_poll() by
avoid disabling BH there, this is okay because be_poll()
can be called either by poll_napi() which already disables
IRQ, or by net_rx_action() which already disables BH.

radeon_ring_restore is freeing the memory for the saved

restore the ring data again on the next try. Additional
to that it shouldn't try the reset infinitely if we have

Alex Deucher c205b232a6 drm/radeon/atom: powergating fixes for DCE6
Power gating is per crtc pair, but the powergating registers
should be called individually.  The hw handles power up/down
properly.  The pair is powered up if either crtc in the pair
is powered up and the pair is not powered down until both
crtcs in the pair are powered down.  This simplifies
programming and should save additional power as the previous
code never actually power gated the crtc pair.

Alex Deucher 8d1af57ae3 drm/radeon/atom: rework DIG modesetting on DCE3+
The ordering is important and the current drm code
wasn't cutting it for modern DIG encoders.  We need
to have information about crtc before setting up
the encoders so I've shifted the ordering a bit.
Probably we'll need a full rework akin to danvet's
recent intel patchs.  This patch fixes numerous
issues with DP bridge chips and makes link training
much more reliable.

Checking of the second colorbuffer was skipped on r700, because
CB_TARGET_MASK was 0xf. With r600, CB_TARGET_MASK is changed to 0xff,
so we must set the number of samples of the second colorbuffer to 1 in order
to pass the CS checker.
The DRM version is bumped, because RESOLVE_BOX is always rejected without this

 - Improvements to the buffered and direct write IO plugging from

 - Abstract out the mapping of a bio in a request, and use that to

   instead of a full request.

 - Regression fix from Hugh, fixing up a patch that went into the
   previous release cycle (and marked stable, too) attempting to prevent
   a loop in __getblk_slow().

 - Updates to discard requests, fixing up the sizing and how we align
   them.  Also a change to disallow merging of discard requests, since
   that doesn't really work properly yet.

Calvin Walton a51d4ed01e i915: Quirk no_lvds on Gigabyte GA-D525TUD ITX motherboard
This board is incorrectly detected as having an LVDS connector,
resulting in the VGA output (the only available output on the board)
showing the console only in the top-left 1024x768 pixels, and an extra
LVDS connector appearing in X.

It's a desktop Mini-ITX board using an Atom D525 CPU with an NM10

noticed the issue because I've been running it headless for most of its

Tomi Valkeinen 35d6786648 OMAPDSS: Fix SDI PLL locking
Commit f476ae9dab (OMAPDSS: APPLY: Remove
DISPC writes to manager's lcd parameters in interface) broke the SDI
output, as it causes the SDI PLL locking to fail.

LCLK and PCLK divisors are located in shadow registers, and we normally
write them to DISPC registers when enabling the output.  However, SDI
uses pck-free as source clock for its PLL, and pck-free is affected by
the divisors. And as we need the PLL before enabling the output, we need
to write the divisors early.

It seems just writing to the DISPC register is enough, and we don't need
to care about the shadow register mechanism for pck-free. The exact
reason for this is unknown.

Dave Airlie d8636a2717 fbcon: fix race condition between console lock and cursor timer (v1.1)
So we've had a fair few reports of fbcon handover breakage between
efi/vesafb and i915 surface recently, so I dedicated a couple of
days to finding the problem.

Essentially the last thing we saw was the conflicting framebuffer
message and that was all.

So after much tracing with direct netconsole writes (printks
under console_lock not so useful), I think I found the race.

Thread A (driver load)    Thread B (timer thread)
  unbind_con_driver ->              |
  bind_con_driver ->                |
  vc->vc_sw->con_deinit ->          |
  fbcon_deinit ->                   |
  console_lock()                    |
      |                             |
      |                       fbcon_flashcursor timer fires
      |                       console_lock() <- blocked for A
      |
      |
fbcon_del_cursor_timer ->
  del_timer_sync
  (BOOM)

Of course because all of this is under the console lock,
we never see anything, also since we also just unbound the active
console guess what we never see anything.

Hopefully this fixes the problem for anyone seeing vesafb->kms
driver handoff.

v1.1: add comment suggestion from Alan.

Pull networking update from David Miller:
 "A couple weeks of bug fixing in there.  The largest chunk is all the
  broken crap Amerigo Wang found in the netpoll layer."

 1) netpoll and it's users has several serious bugs:
    a) uses GFP_KERNEL with locks held
    b) interfaces requiring interrupts disabled are called with them
       enabled
    c) and vice versa
    d) VLAN tag demuxing, as per all other RX packet input paths, is not
       applied

    All from Amerigo Wang.

 2) Hopefully cure the ipv4 mapped ipv6 address TCP early demux bugs for
    good, from Neal Cardwell.

 3) Unlike AF_UNIX, AF_PACKET sockets don't set a default credentials
    when the user doesn't specify one explicitly during sendmsg().
    Instead we attach an empty (zero) SCM credential block which is
    definitely not what we want.  Fix from Eric Dumazet.

 4) IPv6 illegally invokes netdevice notifiers with RCU lock held, fix
    from Ben Hutchings.

 5) inet_csk_route_child_sock() checks wrong inet options pointer, fix
    from Christoph Paasch.

 6) When AF_PACKET is used for transmit, packet loopback doesn't behave
    properly when a socket fanout is enabled, from Eric Leblond.

 7) On bluetooth l2cap channel create failure, we leak the socket, from
    Jaganath Kanakkassery.

 8) Fix all the netprio file handling bugs found by Al Viro, from John
    Fastabend.

 9) Several error return and NULL deref bug fixes in networking drivers
    from Julia Lawall.

10) A large smattering of struct padding et al.  kernel memory leaks to
    userspace found of Mathias Krause.

11) Conntrack expections in netfilter can access an uninitialized timer,
    fix from Pablo Neira Ayuso.

12) Several netfilter SIP tracker bug fixes from Patrick McHardy.

13) IPSEC ipv6 routes are not initialized correctly all the time,
    resulting in an OOPS in inet_putpeer().  Also from Patrick McHardy.

14) Bridging does rcu_dereference() outside of RCU protected area, from

Alexandre Bounine 3670e7e12e rapidio/tsi721: fix inbound doorbell interrupt handling
Make sure that there is no doorbell messages left behind due to disabled
interrupts during inbound doorbell processing.

The most common case for this bug is loss of rionet JOIN messages in
systems with three or more rionet participants and MSI or MSI-X enabled.
As result, requests for packet transfers may finish with "destination
unreachable" error message.

Atsushi Nemoto 7dbfb315b2 drivers/rtc/rtc-rs5c348.c: fix hour decoding in 12-hour mode
Correct the offset by subtracting 20 from tm_hour before taking the
modulo 12.

[ "Why 20?" I hear you ask. Or at least I did.

  Here's the reason why: RS5C348_BIT_PM is 32, and is - stupidly -
  included in the RS5C348_HOURS_MASK define.  So it's really subtracting
  out that bit to get "hour+12".  But then because it does things modulo
  12, it needs to add the 12 in again afterwards anyway.

  This code is confused.  It would be much clearer if RS5C348_HOURS_MASK
  just didn't include the RS5C348_BIT_PM bit at all, then it wouldn't
  need to do the silly subtract either.

  Whatever. It's all just math, the end result is the same.   - Linus ]

Robin Holt 7838f994b4 drivers/misc/sgi-xp/xpc_uv.c: SGI XPC fails to load when cpu 0 is out of IRQ resources
On many of our larger systems, CPU 0 has had all of its IRQ resources
consumed before XPC loads.  Worst cases on machines with multiple 10
GigE cards and multiple IB cards have depleted the entire first socket
of IRQs.

This patch makes selecting the node upon which IRQs are allocated (as
well as all the other GRU Message Queue structures) specifiable as a
module load param and has a default behavior of searching all nodes/cpus
for an available resources.

Huang Ying 3d8387efe1 PCI/PM: Fix config reg access for D3cold and bridge suspending
This patch fixes the following bug:

http://marc.info/?l=linux-pci&m=134338059022620&w=2

Where lspci does not work properly if a device and the corresponding
parent bridge (such as PCIe port) is suspended.  This is because the
device configuration space registers will be not accessible if the
corresponding parent bridge is suspended or the device is put into
D3cold state.

To solve the issue, the bridge/PCIe port connected to the device is
put into active state before read/write configuration space registers.
If the device is in D3cold state, it will be put into active state
too.

To avoid resume/suspend PCIe port for each configuration register
read/write, a small delay is added before the PCIe port to go
suspended.

Huang Ying ea8c88f13d PCI/PM: Keep parent bridge active when probing device
This patch fixes the following bug:

http://marc.info/?l=linux-pci&m=134329923124234&w=2

The root cause of the bug is as follow.

If a device is not bound with the corresponding driver, the device
runtime PM will be disabled and the device will be put into suspended
state.  So that, the bridge/PCIe port connected to it may be put into
suspended and low power state.  When do probing for the device later,
because the bridge/PCIe port connected to it is in low power state,
the IO access to device may fail.

To solve the issue, the bridge/PCIe port connected to the device is
put into active state before probing.

Huang Ying 4f9c1397e2 PCI/PM: Enable D3/D3cold by default for most devices
This patch fixes the following bug:

http://marc.info/?l=linux-usb&m=134318961120825&w=2

Originally, device lower power states include D1, D2, D3.  After that,
D3 is further divided into D3hot and D3cold.  To support both scenario
safely, original D3 is mapped to D3cold.

When adding D3cold support, because worry about some device may have
broken D3cold support, D3cold is disabled by default.  This disable D3
on original platform too.  But some original platform may only have
working D3, but no working D1, D2.  The root cause of the above bug is
it too.

To deal with this, this patch enables D3/D3cold by default for most
devices.  This restores the original behavior.  For some devices that
suspected to have broken D3cold support, such as PCIe port, D3cold is
disabled by default.

Alan Cox f5869a8308 drm: stop vmgfx driver explosion
If you do a page flip with no flags set then event is NULL. If event is
NULL then the vmw_gfx driver likes to go digging into NULL and extracts
NULL->base.file_priv.

On a modern kernel with NULL mapping protection it's just another oops,
without it there are some "intriguing" possibilities.

What it should do is an open question but that for the driver owners to
sort out.
