DaVinci fixes for v3.6
Fix an interrupt handling issue with cp_intc which
was causing occasional spurious interrupts with DA850 EVM
* tag 'davinci-v3.6-fixes' of git://gitorious.org/linux-davinci/linux-davinci:
ARM: davinci: da8xx: fix interrupt handling
CP_INTC code in entry-macro.S code reads SECR1n register to see if
an interrupt was indeed pending. This register is actually marked as
write-only in the OMAP-L138 TRM. Moreover, the code just checks to see
the entire register is non-zero and does not check a specific interrupt
number.
Fix this to use interrupt pending bit in GIPR register for this purpose.
GIPR register is already being read to know the highest priority interrupt
pending.

commit 164e0cbf60 (ARM: OMAP3/4: consolidate cpuidle Makefile) added
an OMAP-specific dependency from CPU_IDLE to CONFIG_PM. This causes
some randconfig warnings when CONFIG_PM has unmet dependencies:
warning: (ARCH_OMAP3 && ARCH_OMAP4) selects PM which has unmet direct dependencies (PM_SLEEP || PM_RUNTIME)
warning: (ARCH_OMAP3 && ARCH_OMAP4) selects PM which has unmet direct dependencies (PM_SLEEP || PM_RUNTIME)
warning: (ARCH_OMAP3 && ARCH_OMAP4) selects PM which has unmet direct dependencies (PM_SLEEP || PM_RUNTIME)
Fix this by making the dependency on CONFIG_PM_RUNTIME (which in turn
will enable CONFIG_PM.)

Commit f948501b36c6 ("Make hard_irq_disable() actually hard-disable
interrupts") caused check_and_cede_processor to stop working.
->irq_happened will never be zero right after a hard_irq_disable
so the compiler removes the call to cede_processor completely.
The bug was introduced back in the lazy interrupt handling rework
of 3.4 but was hidden until recently because hard_irq_disable did
nothing.
This issue will eventually appear in 3.4 stable since the
hard_irq_disable fix is marked stable, so mark this one for stable
too.

As I was adding code that affects all archs, I started testing function
tracer against PPC64 and found that it currently locks up with 3.4
kernel. I figured it was due to tracing a function that shouldn't be, so
I went through the following process to bisect to find the culprit:
cat /debug/tracing/available_filter_functions > t
num=`wc -l t`
sed -ne "1,${num}p" t > t1
let num=num+1
sed -ne "${num},$p" t > t2
cat t1 > /debug/tracing/set_ftrace_filter
echo function /debug/tracing/current_tracer
<failed? bisect t1, if not bisect t2>
It finally came down to this function: restore_interrupts()
I'm not sure why this locks up the system. It just seems to prevent
scheduling from occurring. Interrupts seem to still work, as I can ping
the box. But all user processes freeze.
When restore_interrupts() is not traced, function tracing works fine.

In entry_64.S version of ret_from_except_lite, you'll notice that
in the !preempt case, after we've checked MSR_PR we test for any
TIF flag in _TIF_USER_WORK_MASK to decide whether to go to do_work
or not. However, in the preempt case, we do a convoluted trick to
test SIGPENDING only if PR was set and always test NEED_RESCHED ...
but we forget to test any other bit of _TIF_USER_WORK_MASK !!! So
that means that with preempt, we completely fail to test for things
like single step, syscall tracing, etc...
This should be fixed as the following path:
- Test PR. If not set, go to resume_kernel, else continue.
- If go resume_kernel, to do that original do_work.
- If else, then always test for _TIF_USER_WORK_MASK to decide to do
that original user_work, else restore directly.

During kernel init, the AM3505/AM3517 UART4 cannot complete its softreset:
omap_hwmod: uart4: softreset failed (waited 10000 usec)
This also results in another warning later in the boot process:
omap_hwmod: uart4: enabled state can only be entered from initialized, idle, or disabled state
From empirical observation, the AM35xx UART4 IP block requires either
uart1_fck or uart2_fck to be enabled while UART4 resets. Otherwise
the reset will never complete. So this patch adds uart1_fck as an
optional clock for UART4 and adds the appropriate hwmod flag to cause
uart1_fck to be enabled during the reset process. (The choice of
uart1_fck over uart2_fck was arbitrary.)
Unfortunately this observation raises many questions. Is it necessary
for uart1_fck or uart2_fck to be controlled with uart4_fck for the
UART4 to work correctly? What exactly do the AM35xx UART4 clock
tree and the related PRCM idle management FSMs look like? If anyone
has the ability to answer these questions through empirical functional
testing, or hardware information from the AM35xx designers, it would
be greatly appreciated.

Add missing terminators to the arrays of IRQ, DMA, and address space
structure records in the AM35xx UART4 hwmod data. Without these
terminators, the following warnings appear on boot:
omap_uart.3: failed to claim resource 58
omap_device: omap_uart: build failed (-16)
WARNING: at /home/paul/linux/arch/arm/mach-omap2/serial.c:375 omap_serial_init_port+0x198/0x284()
Could not build omap_device for omap_uart: uart4.
Also, AM35xx uart4_fck has an incorrect parent clock pointer. Fix it
and clean up a whitespace issue.
Fix some incorrectly-named macros related to AM35xx UART4.

Partially fix the hwmod data for the AM35xx USB OTG hwmod. This
should resolve the following boot warning on AM35xx platforms:
omap_hwmod: am35x_otg_hs: cannot be enabled for reset (3)
While here, also fix the clkdev records, to avoid warnings about
duplicate clock aliases.
The hwmod is also connected to the wrong interconnect. It should be
connected to the IPSS, not the L4 CORE. But that is left for a future
fix, since it probably has a dependency on some hwmod core changes.

The problem is that currently none of the clocks are being registered for
OMAP4470 devices and so on boot-up no clocks can be found and the kernel panics.
This fix allows the kernel to boot without failure using a simple RAMDISK file
system on OMAP4470 blaze board.
Per feedback from Paul and Benoit the 4470 clock data is incomplete for new
modules such as the 2D graphics block that has been added to the 4470.
Therefore add a warning to indicate that the clock data is incomplete.

There was a stray %s left from testing, remove it.
Add -w to the #! line (which is parsed by Perl even if the Perl

commit 8259573b (ARM: OMAP2+: nand: Make board_onenand_init() visible
to board code) broke the build for configs with OneNAND disabled. By
removing the static in the header file, it created a duplicate definition
in the .c and the .h files, resuling in a build error:

It makes sense to label "Digital Thermal Sensor" as "DTS", but
unfortunately the string "dts" was already used for "Debug Store", and
/proc/cpuinfo is a user space ABI.
Therefore, rename this to "dtherm".
This conflict went into mainline via the hwmon tree without any x86
maintainer ack, and without any kind of hint in the subject.

IOMMU-aware dma_alloc_attrs() implementation allocates buffers in
power-of-two chunks to improve performance and take advantage of large
page mappings provided by some IOMMU hardware. However current code, due
to a subtle bug, allocated those chunks in the smallest-to-largest
order, what completely killed all the advantages of using larger than
page chunks. If a 4KiB chunk has been mapped as a first chunk, the
consecutive chunks are not aligned correctly to the power-of-two which
match their size and IOMMU drivers were not able to use internal
mappings of size other than the 4KiB (largest common denominator of
alignment and chunk size).
This patch fixes this issue by changing to the correct largest-to-smallest
chunk size allocation sequence.
