Fixes this section mismatch:
WARNING: vmlinux.o(.text+0x145e4): Section mismatch in reference from the function
smp_add_present_cpu() to the function .cpuinit.text:register_cpu()
The function smp_add_present_cpu() references
the function __cpuinit register_cpu().
This is often because smp_add_present_cpu lacks a __cpuinit
annotation or the annotation of register_cpu is wrong.

The debug_register/unregister_view() functions call debugfs_remove()
while holding the debug_info spinlock. Because debugfs_remove() takes
a mutex and therefore can sleep this is not allowed. To fix the problem
we give up the debug_info lock before calling debugfs_remove().
The following shows the lockdep message:

Noticed while reviewing the fence locking in the radeon pageflip
handler.
v2: Instead of grabbing the bdev->fence_lock in object_transfer just
move the single callsite of that function a few lines, so that it is
protected by the fence_lock. Suggested by Jerome Glisse.
v3: Fix typo in commit message.

With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.
Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.

Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem
makes memory leak. release function of dma-buf cannot be called because f_count
of dma-buf increased by importing gem and gem ref count cannot be decrease
because of exported dma-buf.
So I add dma_buf_put() for imported gem come from its own gem into each drivers
having prime_import and prime_export capabilities. With this, only gem ref
count is increased if importing gem exported from gem of same driver.

Summary:
- change exynos file license
. Most of exynos files had been copied from some randome
file and not updated correctly(wrong company name used).
This was our mistakes so chagnes it correctly. For this,
I'm not sure that this patch should go to -fix or -next.
So please give me any comment if there is any problem.
- consider buffer allocation without iommu
. Without iommu, dma_alloc_attrs function allocates some
memory region and returns cpu address so this patch makes
the cpu address to be set to buf->kvaddr correctly
- cleanups to ipp relevant codes.
- use common finish page flip function
. to avoid the duplication of same code, use
exynos_drm_crtc_finish_pageflip function commonly instead
of each one.
- fix fimd resume issue.
. when fimd was turned off by suspend, there was one issue that
the fimd wasn't turned on by resume so fix it chaing resume
condition.

This solves runtime failures while trying to enable WDT3 related
functionality on firmware load, however it does affect other clocks
controlled by the driver. Seen on 3.8-rc1.
CCF provides clk_prepare and clk_unprepare for enable and disable
operations respectively, this needs to be called in the correct
order while handling clocks.
Code path to enable/disable dsp clocks can still be reached from an
atomic context, hence we can't use clk_prepare_enable and
clk_disable_unprepare yet.

Éric Piel reported a kernel oops in the "comedi_test" module. It was a
NULL pointer dereference within `waveform_ai_interrupt()` (actually a
timer function) that sometimes occurred when a running asynchronous
command is cancelled (either by the `COMEDI_CANCEL` ioctl or by closing
the device file).
This seems to be a race between the caller of `waveform_ai_cancel()`
which on return from that function goes and tears down the running
command, and the timer function which uses the command. In particular,
`async->cmd.chanlist` gets freed (and the pointer set to NULL) by
`do_become_nonbusy()` in "comedi_fops.c" but a previously scheduled
`waveform_ai_interrupt()` timer function will dereference that pointer
regardless, leading to the oops.
Fix it by replacing the `del_timer()` call in `waveform_ai_cancel()`
with `del_timer_sync()`.

When a low-level comedi driver auto-configures a device, a `struct
comedi_dev_file_info` is allocated (as well as a `struct
comedi_device`) by `comedi_alloc_board_minor()`. A pointer to the
hardware `struct device` is stored as a cookie in the `struct
comedi_dev_file_info`. When the low-level comedi driver
auto-unconfigures the device, `comedi_auto_unconfig()` uses the cookie
to find the `struct comedi_dev_file_info` so it can detach the comedi
device from the driver, clean it up and free it.
A problem arises if the user manually unconfigures and reconfigures the
comedi device using the `COMEDI_DEVCONFIG` ioctl so that is no longer
associated with the original hardware device. The problem is that the
cookie is not cleared, so that a call to `comedi_auto_unconfig()` from
the low-level driver will still find it, detach it, clean it up and free
it.
Stop this problem occurring by always clearing the `hardware_device`
cookie in the `struct comedi_dev_file_info` whenever the
`COMEDI_DEVCONFIG` ioctl call is successful.

The minimum period was set to 357 ns, while the divider for these boards is 50
ns. This prevented to output at maximum speed as ni_ao_cmdtest() would return
357 but would not accept it.
Not sure why it was set to 357 ns (this was done before the git history,
which starts 5 years ago). My guess is that it comes from reading the
specification stating a 2.8 MHz rate (~ 357 ns). The latest
specification states a 2.86 MHz rate (~ 350 ns), which makes a lot
more sense.

This patch changes the omapdrm KMS to bypass the omapdss "compat"
layer and use the core omapdss API directly. This solves some layering
issues that would cause unpin confusion vs GO bit status, because we
would not know whether a particular pageflip or overlay update has hit
the screen or not. Now instead we explicitly manage the GO bits in
dispc and handle the vblank/framedone interrupts ourself so that we
always know which buffers are being scanned out at any given time, and
so on.
As an added bonus, we no longer leave the last overlay buffer pinned
when the display is disabled, and have been able to add the previously
missing vblank event handling.

Recent versions of udev cause synchronous firmware loading from the
probe routine to fail because the request to user space would time
out. The original fix for b43 (commit 6b6fa58) moved the firmware
load from the probe routine to a work queue, but it still used synchronous
firmware loading. This method is OK when b43 is built as a module;
however, it fails when the driver is compiled into the kernel.
This version changes the code to load the initial firmware file
using request_firmware_nowait(). A completion event is used to
hold the work queue until that file is available. This driver
reads several firmware files - the remainder can be read synchronously.
On some test systems, the async read fails; however, a following synch
read works, thus the async failure falls through to the sync try.

by Stefan Richter, update the TODO file.
- Clarify purpose of TODO file
- Remove firewire item #4. As discussed in this conversation
https://lkml.org/lkml/2012/11/13/564 knowing the AR buffer size
is not a hard requirement. The required rx buffer size can be
determined experimentally.
- Remove firewire item #5. This was a private note for further
experimentation.
- Change firewire item #1. Change suggested header from uapi header
to kernel-only header.

Debug port in-use determination must be done before the controller gets
reset the first time, i.e. before the call to ehci_setup() as of commit
1a49e2ac9651df7349867a5cf44e2c83de1046af. That commit effectively
rendered commit 9fa5780beea1274d498a224822397100022da7d4 useless.
While moving that code around, also fix the BAR determination - the
respective capability field is a 3- rather than a 2-bit one -, and use
PCI_CAP_ID_DBG instead of the literal 0x0a.
It's unclear to me whether the debug port functionality is important
enough to warrant fixing this in stable kernels too.

This patch (as1639) fixes a minor bug in the usbtest driver. Due to
concurrent changes, a test originally written as number 17 got changed
to number 24, but the corresponding change was not made in the log
message. This updates the log message.

Users of mei_amthif_read() expect it leaves dev->device_lock held,
while there is a path where mei_amthif_read() unlocks device_lock
and returns -ERESTARTSYS.
The patch move code locking device_lock back before the return.

Sarah says:
usb-linus: USB core fixes for warm reset
Hi Greg,
Happy New Year! Here's some bug fixes for 3.8. I have usb-next
patches that are based on this set, so please merge your usb-linus
branch into usb-next after this set is applied.
The bulk of the patchset (patches 2-7) improve the USB core's warm
reset error handling.
There's also one patch that fixes an arithmetic error in the xHCI
driver, and another to avoid the "dead ports" issue caused by
unhandled port status change events.
These are all marked for stable.
Sarah Sharp
