Assumption that irq numbers of asic3 gpios start at
IRQ_BOARD_START is certainly wrong - driver may as well
use any other base for its irqs (consider for example
the imaginary case of two ASIC3 chips onboard)
Furthermore, some platforms even don't have IRQ_BOARD_START
defined, so driver will fail to build on them:
-------------------------------------------------------
drivers/mfd/asic3.c: In function 'asic3_gpio_to_irq':
drivers/mfd/asic3.c:530: error: 'IRQ_BOARD_START' undeclared (first use in this function)

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.

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.

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.

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.

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.

Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE
register states are not saved/restored at context switch. The default state
of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the
ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour
when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing
covert communication - eg between userspace tasks running inside chroot
jails.
This patch sets up TEECR in order to prevent user-space access to TEEHBR
when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to
access TEEHBR.

During booting of cpu1, there is a short window where cpu1
is online, but not active where cpu1 is occupied by waiting
to become active. If cpu0 then decides to schedule something
on cpu1 and wait for it to complete, before cpu0 has set
cpu1 active, we have a deadlock.
Typically it's this CPU frequency transition that happens at
this time, so let's just not wait for it to happen, it will
happen whenever the CPU eventually comes online instead.

Commit 26f41062f2 ("PCI: check for pci bar restore completion and
retry") attempted to address problems with PCI BAR restoration on
systems where FLR had not been completed before pci_restore_state() was
called, but it did that in an utterly wrong way.
First off, instead of retrying the writes for the BAR registers only, it
did that for all of the PCI config space of the device, including the
status register (whose value after the write quite obviously need not be
the same as the written one). Second, it added arbitrary delay to
pci_restore_state() even for systems where the PCI config space
restoration was successful at first attempt. Finally, the mdelay(10) it
added to every iteration of the writing loop was way too much of a delay
for any reasonable device.
All of this actually caused resume failures for some devices on Mikko's
system.
To fix the regression, make pci_restore_state() only retry the writes
for BAR registers and only wait if the first read from the register
doesn't return the written value. Additionaly, make it wait for 1 ms,
instead of 10 ms, after every failing attempt to write into config
space.

Commit 18a4d0a22e ("[SCSI] Handle disk devices which can not process
medium access commands") introduced a bug in which we would attempt to
dereference the scsi driver even when the device had no ULD attached.
Ensure that a driver is registered and make the driver accessor function
more resilient to errors during device discovery.

As reported by David Gibson, current code handles PAGE_SIZE != 4k
completely wrong which can lead to guest memory corruption errors:
- page_to_balloon_pfn is wrong: e.g. on system with 64K page size
it gives the same pfn value for 16 different pages.
- we also need to convert back to linux pfns when we free.
- for each linux page we need to tell host about multiple balloon
pages, but code only adds one pfn to the array.
This patch fixes all that, tested with a 64k ppc64 kernel.

Although virtio config space fields are usually in guest-native endian,
the spec for the virtio balloon device explicitly states that both fields
in its config space are little-endian.
However, the current virtio_balloon driver does not have a suitable endian
swap for the 'num_pages' field, although it does have one for the 'actual'
field. This patch corrects the bug, adding sparse annotation while we're
at it.

Now that we have OPP layer, and OMAP CPUfreq driver is using it, we no
longer need/use the clock framework code for filling up CPUfreq
tables. Remove it.
Removing this code also eliminates build errors when CPU_FREQ_TABLE
support is not enabled.
Thanks to Russell King for pointing out the parts I missed under
plat-omap in the original version and also pointing out the build
errors when CPUFREQ_TABLE support was not enabled.

These were incorrectly introduced and can cause problems for of_irq_init.

If a '$PERF_BUILDID_DIR'(typically $HOME/.debug) is a symbolic link
directory, cutting of the path will fail.
Here is an example where a buildid directory is a symbolic link.
/ # ls -al /root
lrwxrwxrwx 1 root root 13 Mar 26 2012 /root -> opt/home/root
/ # cd ~
/opt/home/root # perf record -a -g sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.322 MB perf.data (~14057 samples) ]
/opt/home/root # perf archive
tar: Removing leading `/' from member names
Now please run:
$ tar xvf perf.data.tar.bz2 -C ~/.debug
wherever you need to run 'perf report' on.
/opt/home/root # mkdir temp
/opt/home/root # tar xf perf.data.tar.bz2 -C ./temp
/opt/home/root # find ./temp -name "*kernel*"
./temp/opt/home/root/.debug/[kernel.kallsyms]
-> If successfully cut off the path, [kernel.kallsyms] is located
in top of the archived file.
This patch enables to cut correctly even if the buildid directory
is a symbolic link.

Currently the parsers objects (bison/flex related) are each time perf
is built. No matter the generated files are already in place, the
parser generation is executed every time.
Changing the rules to have proper flex/bison objects generation
dependencies.
The parsers code is not rebuilt until the flex/bison source files
are touched. Also when flex/bison source is changed, only dependent
objects are rebuilt.

GCC's NULL is actually __null, which allows detecting some questionable
NULL usage and warn about it. Moreover each platform/compiler should
have its own stddef.h anyway (which is different from linux/stddef.h).
So there's no good reason to leak kernel's NULL to userspace and
override what the compiler provides.
