5ae256dcd9 ARM: OMAP: serial: Fix the ocp smart idlemode handling bug
The current serial UART code, while fidling with ocp idlemode bits,
forget about the smart idle wakeup bit even if it is supported by
UART IP block. This will lead to missing the module wakeup on OMAP's
where the smart idle wakeup is supported.

This was the root cause of the console sluggishness issue, I have been
observing on OMAP4 devices and also can be potential reason for some
other UART wakeup issues.

bce492c04b ARM: OMAP2+: UART: Fix incorrect population of default uart pads
Commit (7496ba3  ARM: OMAP2+: UART: Add default mux for all uarts)
wrongly added muxing of default pads for all uarts. This causes
breakage on multiple boards using uart pins for alternate functions.

For example, on zoom3 random oopses can be seen with nfsroot as
the smsc911x ethernet FIFO timings on GPMC bus are controlled
by gpmc_wait2 and gpmc_wait3 pins. This means we can't mux these
pads to uart4 functionality as commit 7496ba3 was doing.

Not all boards tend to use all uarts and most of unused uart pins
are muxed for other purpose. This commit breaks the modules which
where trying to use unused uart pins on their boards.

So remove the default pad muxing. Note that this is not a complete
fix, as we now rely on bootloader set muxing for the uart wake-up
events. Further patching is needed to enable wake-up events for
uarts that are already muxed to uart mode.

e8e937be97 xen/gntdev: do not set VM_PFNMAP
Since we are using the m2p_override we do have struct pages
corresponding to the user vma mmap'ed by gntdev.

Removing the VM_PFNMAP flag makes get_user_pages work on that vma.
An example test case would be using a Xen userspace block backend

938ed25008 m68knommu: make sure 2nd FEC eth interface pins are enabled on 5275 ColdFire

But it is still being used to set the multi-function pins when compiling
for a ColdFire 527[45] SoC that has 2 ethernet interfaces. Remove the
last remaining uses of this define, and so fix the setting of the pins
for the 2nd ethernet interface.

cdd5983063 virtio: fixes on top of 3.4-rc2
Here are some virtio fixes for 3.4:
 a test build fix, a patch by Ren fixing naming for systems with a massive
 number of virtio blk devices, and balloon fixes for powerpc
 by David Gibson.
 
 There was some discussion about Ren's patch for virtio disc naming: some people
 wanted to move the legacy name mangling function to the block core.  But
 there's no concensus on that yet, and we can always deduplicate later.
 Added comments in the hope that this will stop people from
 copying this legacy naming scheme into future drivers.

a6cb9ee7ca PCI: Retry BARs restoration for Type 0 headers only
Some shortcomings introduced into pci_restore_state() by commit
26f41062f2 ("PCI: check for pci bar restore completion and retry")
have been fixed by recent commit ebfc5b802f ("PCI: Fix regression in
pci_restore_state(), v3"), but that commit treats all PCI devices as
those with Type 0 configuration headers.

That is not entirely correct, because Type 1 and Type 2 headers have
different layouts.  In particular, the area occupied by BARs in Type 0
config headers contains the secondary status register in Type 1 ones and
it doesn't make sense to retry the restoration of that register even if
the value read back from it after a write is not the same as the written
one (it very well may be different).

For this reason, make pci_restore_state() only retry the restoration
of BARs for Type 0 config headers.  This effectively makes it behave
as before commit 26f41062f2 for all header types except for Type 0.

c76f39bddb ia64: fix futex_atomic_cmpxchg_inatomic()
Michel Lespinasse cleaned up the futex calling conventions in commit
37a9d912b2 ("futex: Sanitize cmpxchg_futex_value_locked API").

But the ia64 implementation was subtly broken.  Gcc does not know that
register "r8" will be updated by the fault handler if the cmpxchg
instruction takes an exception.  So it feels safe in letting the
initialization of r8 slide to after the cmpxchg.  Result: we always
return 0 whether the user address faulted or not.

Fix by moving the initialization of r8 into the __asm__ code so gcc
won't move it.

1fcb57d0f6 ARM: OMAP3: USB: Fix the EHCI ULPI PHY reset issue
It is observed that the echi ports of 3430 sdp board
are not working due to the random timing of programming
the associated GPIOs of the ULPI PHYs of the EHCI for reset.
If the PHYs are reset at during usbhs core driver, host ports will
not work because EHCI driver is loaded after the resetting PHYs.
The PHYs should be in reset state while initializing the EHCI
controller.
The code which does the GPIO pins associated with the PHYs
are programmed to reset is moved from the USB host core driver
to EHCI driver.

edffaa031e usb: fixes for v3.4-rc cycle
Here are the fixes I have queued for v3.4-rc cycle so far.
 
 It includes fixes on many of the gadget drivers and a few
 of the UDC controller drivers.
 
 For musb we have a fix for a kernel oops when unloading
 omap2430.ko glue layer, proper error checking for pm_runtime_*,
 fix for the ULPI transfer block, and a bug fix in musb_cleanup_urb
 routine.
 
 For s3c-hsotg we have mostly FIFO-related fixes (proper TX FIFO
 allocation, TX FIFO corruption fix in DMA mode) but also a couple
 of minor fixes (fixing maximum packet size for ep0 and fix for
 big transfers with DMA).
 
 For the dwc3 driver we have a memory leak fix, a very important
 fix for USB30CV with SetFeature tests and the hability to handle
 ep0 requests bigger than wMaxPacketSize.
 
 On top of that there's a bunch of gadget driver minor fixes adding
 proper section annotations, and fixing up the sysfs interface for
 doing device-initiated connect/disconnect and so on.
 
 All patches have been pending on the mailing list for quite a while
 and look good for your for-linus branch.

usb: fixes for v3.4-rc cycle

Here are the fixes I have queued for v3.4-rc cycle so far.

It includes fixes on many of the gadget drivers and a few
of the UDC controller drivers.

For musb we have a fix for a kernel oops when unloading
omap2430.ko glue layer, proper error checking for pm_runtime_*,
fix for the ULPI transfer block, and a bug fix in musb_cleanup_urb
routine.

For s3c-hsotg we have mostly FIFO-related fixes (proper TX FIFO
allocation, TX FIFO corruption fix in DMA mode) but also a couple
of minor fixes (fixing maximum packet size for ep0 and fix for
big transfers with DMA).

For the dwc3 driver we have a memory leak fix, a very important
fix for USB30CV with SetFeature tests and the hability to handle
ep0 requests bigger than wMaxPacketSize.

On top of that there's a bunch of gadget driver minor fixes adding
proper section annotations, and fixing up the sysfs interface for
doing device-initiated connect/disconnect and so on.

All patches have been pending on the mailing list for quite a while
and look good for your for-linus branch.

8eaeb93933 mfd: Convert twl6040 to i2c driver, and separate it from twl core
Complete the separation of the twl6040 from the twl core since
it is a separate chip, not part of the twl6030 PMIC.

Make the needed Kconfig changes for the depending drivers at the
same time to avoid breaking the kernel build (vibra, ASoC components).

4accdff7a3 mfd : Fix dbx500 compilation error
The ux500 default config enables the db5500 and the db8500.
The incoming cpuidle driver uses the 'prcmu_enable_wakeups'
and the 'prcmu_set_power_state' functions but these ones
are defined but not implemented for the db5500, leading to
an unresolved symbol error at link time. In order to compile,
we have to disable the db5500 support which is not acceptable
for the default config.

I noticed there are also some other functions which are
defined but not implemented.

This patch fix this by removing the functions definitions
and move out of the config section the empty functions which
are normally used when the DB550 config is disabled.
Only the functions which are not implemented are concerned
by this modification.

f9bef081c3 drm/i915: don't clobber the special upscaling lvds timings
This regression has been introduced in

commit ca9bfa7eed
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Sat Jan 28 14:49:20 2012 +0100

    drm/i915: fixup interlaced vertical timings confusion, part 1

Unfortunately that commit failed to take into account that the lvds
code does some special adjustements to the crtc timings for upscaling
an centering.

Fix this by explicitly computing crtc timings in the lvds mode fixup
function and setting a special flag in mode->private_flags if the crtc
timings have been adjusted.

v2: Add a comment to explain the new mode driver private flag,
suggested by Eugeni Dodonov.

v3: Kill the confusing and now redundant set_crtcinfo call in
intel_fixed_panel_mode, noticed by Chris Wilson.

89d786011f m68knommu: move and fix the 68VZ328 platform bootlogo.h
The 68EZ328/bootlogo.h is not actually used in the 68EZ328 platform code
at all. It is used by the 68VZ328 platform code though, so move it to be

Commit c0e0c89c08 ("fix broken boot logo

Modify 68VZ328/bootlogo.h so that the bootlogo bit map is named correctly
for direct use in the C code.

12e993b894 x86-32: fix up strncpy_from_user() sign error
The 'max' range needs to be unsigned, since the size of the user address
space is bigger than 2GB.

We know that 'count' is positive in 'long' (that is checked in the
caller), so we will truncate 'max' down to something that fits in a
signed long, but before we actually do that, that comparison needs to be
done in unsigned.

Bug introduced in commit 92ae03f2ef ("x86: merge 32/64-bit versions of
'strncpy_from_user()' and speed it up").  On x86-64 you can't trigger
this, since the user address space is much smaller than 63 bits, and on
x86-32 it works in practice, since you would seldom hit the strncpy
limits anyway.

I had actually tested the corner-cases, I had only tested them on
x86-64.  Besides, I had only worried about the case of a pointer *close*
to the end of the address space, rather than really far away from it ;)

This also changes the "we hit the user-specified maximum" to return
'res', for the trivial reason that gcc seems to generate better code
that way.  'res' and 'count' are the same in that case, so it really
doesn't matter which one we return.
