Commit 1fcf7ce0c602 (arm: kvm: implement CPU PM notifier) added
support for CPU power-management, using a cpu_notifier to re-init
KVM on a CPU that entered CPU idle.
The code assumed that a CPU entering idle would actually be powered
off, loosing its state entierely, and would then need to be
reinitialized. It turns out that this is not always the case, and
some HW performs CPU PM without actually killing the core. In this
case, we try to reinitialize KVM while it is still live. It ends up
badly, as reported by Andre Przywara (using a Calxeda Midway):
[ 3.663897] Kernel panic - not syncing: unexpected prefetch abort in Hyp mode at: 0x685760
[ 3.663897] unexpected data abort in Hyp mode at: 0xc067d150
[ 3.663897] unexpected HVC/SVC trap in Hyp mode at: 0xc0901dd0
The trick here is to detect if we've been through a full re-init or
not by looking at HVBAR (VBAR_EL2 on arm64). This involves
implementing the backend for __hyp_get_vectors in the main KVM HYP
code (rather small), and checking the return value against the
default one when the CPU notifier is called on CPU_PM_EXIT.

Pull ARM SoC fixes from Olof Johansson:
"A collection of fixes for ARM platforms. Most are fixes for DTS
files, mostly from DT conversion on OMAP which is still finding a few
issues here and there.
There's a couple of small stale code removal patches that we usually
queue for the next release instead, but they seemed harmless enough to
bring in now.
Also, a fix for backlight on some PXA platforms, and a cache
configuration fix for Tegra, etc"

The corresponding driver didn't make it into v3.14, so we need to remove
the node. Dove systems fail to boot with the node present and no
driver.
This node will be re-added when the driver makes it to mainline.

Unfortunatly the device tree for older OMAP35xx Overo cannot be used
with newer OMAP36xx and vice-versa. To address this issue, move most of
the Tobi DTS to a common include file, and create model-specific Tobi
DTS.

Tobi expansion board can be used with both OMAP35xx-based Overo,
and OMAP36xx-based Overo. Currently the boot is broken with newer
OMAP36xx-based Overo (Storm and alike). Fix include file and
compatible string to be able to boot newer models.
This will break older models. This will be addressed later.

Therefore, when MTD/ONENAND and MTD/ONENAND/OMAP2 modules are loaded, they are unable

Recent changes to the pwm-backlight driver have made the power supply
mandatory. There is code in the regulator core to deal with situations
where no regulator is specified and provide a dummy, but that works on
DT-based boards only.
The situation can be remedied by adding a dummy regulator during board
initialization.

Pull devicetree fixes from Grant Likely:
"Device tree compatible match order bug fix
This branch contains a bug fix for the way devicetree code identifies
the type of device. Device drivers can contain a list of
of_device_ids, but it more than one entry will match, then the device
driver may choose the wrong one. Commit 105353145e, "match each node
compatible against all given matches first", was queued for v3.14 but
ended up causing other bugs. Commit 06b29e76a7 attempted to fix it
but it had other bugs. Merely reverting the fix and waiting until
v3.15 isn't a good option because there is code in v3.14 that depends
on the revised behaviour to boot.
This branch should finally fixes the problem correctly. This time
instead of just hoping that the patch is correct, this branch also
adds new testcases that validate the behaviour.
The changes in this branch are larger than I would like for a -rc
pull, but moving the test case data out of out of arch/arm so that it
could be validated on other architectures was important"
* tag 'dt-for-linus' of git://git.secretlab.ca/git/linux:
of: Add self test for of_match_node()
of: Move testcase FDT data into drivers/of
of: reimplement the matching method for __of_match_node()

The testcase data is usable by any platform. This patch moves it into
the drivers/of directory so it can be included by any architecture.
Using the test cases requires manually adding #include <testcases.dtsi>
to the end of the boards .dtsi file and enabling CONFIG_OF_SELFTEST. Not
pretty though. A useful project would be to make the testcase code
easier to execute.

arch/arm/mach-tegra/pm.c, kernel/power/console.c and mm/vmpressure.c
were somehow getting slab.h indirectly through cgroup.h which in turn
was getting it indirectly through xattr.h. A scheduled cgroup change
drops xattr.h inclusion from cgroup.h and breaks compilation of these
three files. Add explicit slab.h includes to the three files.
A pending cgroup patch depends on this change and it'd be great if
this can be routed through cgroup/for-3.14-fixes branch.

GFP_ATOMIC is not a single gfp flag, but a macro which expands to the other
flags and LACK of __GFP_WAIT flag. To check if caller wanted to perform an
atomic allocation, the code must test __GFP_WAIT flag presence. This patch
fixes the issue introduced in v3.6-rc5

"A range of ARM fixes. Biggest change is the stage-2 attributes used
for for hyp mode which were wrong. I've killed some bits in a couple
of DT files which turned out not to be required, and a few other
fixes.
One fix touches code outside of arch/arm, which is related to sorting
out the DMA masks correctly. There is a long standing issue with the
conversion from PFNs to addresses where people assume that shifting an
unsigned long left by PAGE_SHIFT results in a correct address. This
is not the case with C: the integer promotion happens at assignment
after evaluation. This fixes the recently introduced dma_max_pfn()
function, but there's a number of other places where we try this
directly on an unsigned long in the mm code"

When unlocking a spinlock, we require the following, strictly ordered
sequence of events:
<barrier> /* dmb */
<unlock>
<barrier> /* dsb */
<sev>
Whilst the code does indeed reflect this in terms of the architecture,
the final <barrier> + <sev> have been contracted into a single inline
asm without a "memory" clobber, therefore the compiler is at liberty to
reorder the unlock to the end of the above sequence. In such a case,
a waiting CPU may be woken up before the lock has been unlocked, leading
to extremely poor performance.
This patch reworks the dsb_sev() function to make use of the dsb()
macro and ensure ordering against the unlock.

During __v{6,7}_setup, we invalidate the TLBs since we are about to
enable the MMU on return to head.S. Unfortunately, without a subsequent
dsb instruction, the invalidation is not guaranteed to have completed by
the time we write to the sctlr, potentially exposing us to junk/stale
translations cached in the TLB.
This patch reworks the init functions so that the dsb used to ensure
completion of cache/predictor maintenance is also used to ensure
completion of the TLB invalidation.

Commit ad6492b8 added much needed memblock_virt_alloc_low() and further
commit 07bacb3 {memblock, bootmem: restore goal for alloc_low} fixed
the issue with low memory limit thanks to Yinghai. But even after all
these fixes, there is still one case where the limit check done with
ARCH_LOW_ADDRESS_LIMIT for low memory fails. Russell pointed out the
issue with 32 bit LPAE machines in below thread.
https://lkml.org/lkml/2014/1/28/364
Since on some LPAE machines where memory start address is beyond 4GB,
the low memory marker in memblock will be set to default
ARCH_LOW_ADDRESS_LIMIT which is wrong. We can fix this by letting
architectures set the ARCH_LOW_ADDRESS_LIMIT using another export
similar to memblock_set_current_limit() but am not sure whether
its worth the trouble. Tell me if you think otherwise.
Rather am just trying to fix that one broken case using
memblock_virt_alloc() in setup code since the memblock.current_limit
is updated appropriately makes it work on all ARM 32 bit machines.

The stage-2 memory attributes are distinct from the Hyp memory
attributes and the Stage-1 memory attributes. We were using the stage-1
memory attributes for stage-2 mappings causing device mappings to be
mapped as normal memory. Add the S2 equivalent defines for memory
attributes and fix the comments explaining the defines while at it.
Add a prot_pte_s2 field to the mem_type struct and fill out the field
for device mappings accordingly.
