git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Fixes for omaps against v4.6-rc1. Mostly minor fixes for the newer
SoCs with few board fixes and a fix for a long time hwmod bug:
- Fix cpsw_emac0 link type for baltos-ir5221
- Fix interrupt type for TWD
- Fix edma memcpy channel allocation for am43x
- Fix am43x-epos sycntimer32k by using the correct assigned clock
- Fix interconnect barrier for dra7
- Fix a long time hwmod bug for updating sysconfig register properly
- Fix flakey booting on dm814x where USB reset needs a delay
And there is one minor change that is not strictly a fix, but is
good to have for proper hardware detection:
- Detect dra7 silicon revision 2.0 properly

The ARM TWD interrupt is a private peripheral interrupt (PPI) and per
the ARM GIC documentation, whether the type for PPIs can be set is
IMPLEMENTATION DEFINED. For OMAP4 devices the PPI type cannot be set and
so when we attempt to set the type for the ARM TWD interrupt it fails.
This has done unnoticed because it fails silently and because we cannot
re-configure the type it has had no impact. Nevertheless fix the type
for the TWD interrupt so that it matches the hardware configuration.

EDMA was allocating DMA channels 32 and 33 for memcpy usage, out of which
channel 33 is actually used by DES crypto engine. This bad allocation of
the channel causes a crash in the DES crypto engine, as the channel
gets configured for memcpy usage instead of hardware <-> memory DMA.
Fixed by allocating DMA channels 58 and 59 for memcpy usage (I2C0 RX/TX),
which are not used by anybody.

commit 55ee7017ee31 ("arm: omap2: board-generic: use omap4_local_timer_init
for AM437x") makes synctimer32k as the clocksource on AM43xx. By default
the synctimer32k is clocked by 32K RTC OSC on AM43xx. But this 32K RTC OSC
is not available on epos boards which makes it fail to boot.
Synctimer32k can also be clocked by a peripheral PLL, so making this as
clock parent for synctimer3k on epos boards.

came in around the same time, unfortunately this seem to have missed
initializing the barrier for DRA7 platforms - omap5_map_io was reused
for dra7 till it was split out by the last patch. barrier_init
needs to be hence carried forward as it is valid for DRA7 family of
processors as they are for OMAP5.

ARM: OMAP2+: first hwmod fix for v4.6-rc
Fix a longstanding bug in the hwmod code that could cause
hardware SYSCONFIG register values to not match the kernel's
idea of what they should be, and that could result in lower
performance during IP block idle entry.
Basic build, boot, and PM test logs are available here:

Commit 127500ccb766f ("ARM: OMAP2+: Only write the sysconfig on idle
when necessary") talks about verification of sysconfig cache value before
updating it, only during idle path. But the patch is adding the
verification in the enable path. So, adding the check in a proper place
as per the commit description.
Not keeping this check during enable path as there is a chance of losing
context and it is safe to do on idle as the context of the register will
never be lost while the device is active.

Commit 1e947bad0b63 ("arm64: KVM: Skip HYP setup when already running
in HYP") re-organized the hyp init code and ended up leaving the CPU
hotplug and PM notifier even if hyp mode initialization fails.
Since KVM is not yet supported with ACPI, the above mentioned commit
breaks CPU hotplug in ACPI boot.
This patch fixes teardown_hyp_mode to properly unregister both CPU
hotplug and PM notifiers in the teardown path.

It was reported that a kernel with CONFIG_ARM_PATCH_IDIV=y stopped
booting when compiled with the upcoming gcc 6. Turns out that turning
a function address into a writable array is undefined and gcc 6 decided
it was OK to omit the store to the first word of the function while
still preserving the store to the second word.
Even though gcc 6 is now fixed to behave more coherently, it is a
mystery that gcc 4 and gcc 5 actually produce wanted code in the kernel.
And in fact the reduced test case to illustrate the issue does indeed
break with gcc < 6 as well.
In any case, let's guard the kernel against undefined compiler behavior
by hiding the nature of the array location as suggested by gcc
developers.

Masahiro Yamada reports that we can fail to set the FW bit in the
auxiliary control register, which enables broadcasting the cache
maintanence operations. This occurs because we only check that the
SMP/nAMP bit is set, rather than checking whether all the bits we
want to be set are set.
Rearrange the code to ensure that all desired bits are set, and only
update the register if we discover some required bits are not set.

When the kernel is running at EL2, it doesn't need init_hyp_mode() to
configure page tables for HYP. This function also registers the CPU
hotplug and lower power notifiers that cause HYP to be re-initialised
after the CPU has been reset.
To avoid losing the register state that controls stage2 translation, move
the registering of these notifiers into init_subsystems(), and add a
is_kernel_in_hyp_mode() path to each callback.

PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
ago with promise that one day it will be possible to implement page
cache with bigger chunks than PAGE_SIZE.
This promise never materialized. And unlikely will.
We have many places where PAGE_CACHE_SIZE assumed to be equal to
PAGE_SIZE. And it's constant source of confusion on whether
PAGE_CACHE_* or PAGE_* constant should be used in a particular case,
especially on the border between fs and mm.
Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
breakage to be doable.
Let's stop pretending that pages in page cache are special. They are
not.
The changes are pretty straight-forward:
- <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
- <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
- PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};
- page_cache_get() -> get_page();
- page_cache_release() -> put_page();
This patch contains automated changes generated with coccinelle using
script below. For some reason, coccinelle doesn't patch header files.
I've called spatch for them manually.
The only adjustment after coccinelle is revert of changes to
PAGE_CAHCE_ALIGN definition: we are going to drop it later.
There are few places in the code where coccinelle didn't reach. I'll
fix them manually in a separate patch. Comments and documentation also
will be addressed with the separate patch.

KASAN needs to know whether the allocation happens in an IRQ handler.
This lets us strip everything below the IRQ entry point to reduce the
number of unique stack traces needed to be stored.
Move the definition of __irq_entry to <linux/interrupt.h> so that the
users don't need to pull in <linux/ftrace.h>. Also introduce the
__softirq_entry macro which is similar to __irq_entry, but puts the
corresponding functions to the .softirqentry.text section.

"There are only three patches this time, most other changes to files in

the change.
Two patches are cleanups for stuff that is no longer needed, the main
change is to adapt the generic version of BUG_ON() for CONFIG_BUG=n to
make it behave consistently with BUG().
This avoids undefined behavior along with a number of warnings about
that undefined behavior in randconfig builds when we keep going on
after hitting a BUG_ON()"

The s3c2410 is allowing board data to overload the default ECC layout
defined inside the driver, but this feature is not used by board
specific definitions.
Kill this field so that we can easily move to a model where ecclayout
are dynamically allocated by the NAND controller driver.

"Here are some final updates for ARM SoC specific dts files:
- The i.MX changes were sent relatively late, and had a dependency on
the clk tree, so I delayed that a bit. Support for the new i.MX6qp
SoC and a couple of new boards is added in this branch.
- Uniphier renames a few files to match the final product names that
were decided by the company, kudos to the kernel developer(s) for
getting support upstream before the product release. Also two
boards are added. The patches were posted early enough and nice
overall, but we forgot to apply them and decided to give it some
more time in linux-next

During the review process of the UniPhier System Bus driver
(drivers/bus/uniphier.c), the current binding of the System Bus
Controller turned out to be no good. In order to make the driver
really usable, we have to switch over to the new binding defined by
Documentation/devicetree/bindings/bus/uniphier-system-bus.txt.
The old binding will be still supported for a while to keep the
backward compatibility.
