Currently arm64 dma_ops is by default made coherent which makes it
opposite in default policy from arm.
Make default dma_ops to be noncoherent (same as arm), as currently there
aren't any dma-capable drivers which assumes coherent ops

Commit d57c33c5daa4 (add generic fixmap.h) added (among other
similar things) set_fixmap_io to deal with early ioremap of devices.
More recently, commit bf4b558eba92 (arm64: add early_ioremap support)
converted the arm64 earlyprintk to use set_fixmap_io. A side effect of
this conversion is that my virtual machines have stopped booting when
I pass "earlyprintk=uart8250-8bit,0x3f8" to the guest kernel.
Turns out that the new earlyprintk code doesn't care at all about
sub-page offsets, and just assumes that the earlyprintk device will
be page-aligned. Obviously, that doesn't play well with the above example.
Further investigation shows that set_fixmap_io uses __set_fixmap instead
of __set_fixmap_offset. A fix is to introduce a set_fixmap_offset_io that
uses the latter, and to remove the superflous call to fix_to_virt
(which only returns the value that set_fixmap_io has already given us).
With this applied, my VMs are back in business. Tested on a Cortex-A57
platform with kvmtool as platform emulation.

Fix for the arm64 kern_addr_valid() function to recognize
virtual addresses in the kernel logical memory map. The
function fails as written because it does not check whether
the addresses in that region are mapped at the pmd level to
2MB or 512MB pages, continues the page table walk to the
pte level, and issues a garbage value to pfn_valid().
Tested on 4K-page and 64K-page kernels.

Start with shrink_dcache_parent(), then scan what remains.
First of all, BUG() is very much an overkill here; we are holding
->s_umount, and hitting BUG() means that a lot of interesting stuff
will be hanging after that point (sync(2), for example). Moreover,
in cases when there had been more than one leak, we'll be better
off reporting all of them. And more than just the last component
of pathname - %pd is there for just such uses...
That was the last user of dentry_lru_del(), so kill it off...

If we find something already on a shrink list, just increment
data->found and do nothing else. Loops in shrink_dcache_parent() and
check_submounts_and_drop() will do the right thing - everything we
did put into our list will be evicted and if there had been nothing,
but data->found got non-zero, well, we have somebody else shrinking
those guys; just try again.

Pull irq fixes from Thomas Gleixner:
"This udpate delivers:
- A fix for dynamic interrupt allocation on x86 which is required to
exclude the GSI interrupts from the dynamic allocatable range.
This was detected with the newfangled tablet SoCs which have GPIOs
and therefor allocate a range of interrupts. The MSI allocations
already excluded the GSI range, so we never noticed before.
- The last missing set_irq_affinity() repair, which was delayed due
to testing issues

earlyprintk=efi,keep will cause kernel hangs while freeing initmem like
below:
VFS: Mounted root (ext4 filesystem) readonly on device 254:2.
devtmpfs: mounted
Freeing unused kernel memory: 880K (ffffffff817d4000 - ffffffff818b0000)
It is caused by efi earlyprintk use __init function which will be freed
later. Such as early_efi_write is marked as __init, also it will use
early_ioremap which is init function as well.
To fix this issue, I added early initcall early_efi_map_fb which maps
the whole efi fb for later use. OTOH, adding a wrapper function
early_efi_map which calls early_ioremap before ioremap is available.
With this patch applied efi boot ok with earlyprintk=efi,keep console=efi

As trace event triggers are now part of the mainline kernel, I added
my trace event trigger tests to my test suite I run on all my kernels.
Now these tests get run under different config options, and one of
those options is CONFIG_PROVE_RCU, which checks under lockdep that
the rcu locking primitives are being used correctly. This triggered
the following splat:

Pull ACPI and power management fixes from Rafael Wysocki:
"A bunch of regression fixes this time. They fix two regressions in
the PNP subsystem, one in the ACPI processor driver and one in the
ACPI EC driver, four cpufreq driver regressions and an unrelated bug
in one of the drivers. The regressions are recent or introduced in
3.14.
Specifics:
- There are two bugs in the ACPI PNP core that cause errors to be
returned if optional ACPI methods are not present. After an ACPI
core change made in 3.14 one of those errors leads to serial port
suspend failures on some systems. Fix from Rafael J Wysocki.
- A recently added PNP quirk related to Intel chipsets intorduced a
build error in unusual configurations (PNP without PCI). Fix from
Bjorn Helgaas.
- An ACPI EC workaround related to system suspend on Samsung machines
added in 3.14 introduced a race causing some valid EC events to be
discarded. Fix from Kieran Clancy.
- The acpi-cpufreq driver fails to load on some systems after a 3.14
commit related to APIC ID parsing that overlooked one corner case.
Fix from Lan Tianyu.
- Fix for a recently introduced build problem in the ppc-corenet
cpufreq driver from Tim Gardner.
- A recent cpufreq core change to ensure serialization of frequency
transitions for drivers with a ->target_index() callback overlooked
the fact that some of those drivers had been doing operations
introduced by it into the core already by themselves. That
resulted in a mess in which the core and the drivers try to do the
same thing and block each other which leads to deadlocks. Fixes
for the powernow-k7, powernow-k6, and longhaul cpufreq drivers from
Srivatsa S Bhat.
- Fix for a computational error in the powernow-k6 cpufreq driver
from Srivatsa S Bhat"

of/irq: do irq resolution in platform_get_irq
changed platform_get_irq() which now returns EINVAL and EPROBE_DEFER,
in addition to ENXIO. If there's no interrupt for mvmdio, platform_get_irq()
returns EINVAL, but we currently check only for ENXIO.
Fix this by looking for a positive integer, which is the proper way of
validating a virtual interrupt number.

There appear to be a crop of new hardware where the vbios is not
available from PROM/PRAMIN, but there is a valid _ROM method in ACPI.
The data read from PCIROM almost invariably contains invalid

way to try to obtain a valid vbios image.

usb: fixes for v3.15-rc4
Small pull request this time containing only 3 patches.
One patch is fixing at91 resource retrieval, one fixes a
conditional in the generic OTG FSM and another fixes a
state transition also on our generic OTG FSM.

Since commit 204dec93eaa "ASoC: fsl: Allow to select individual common
options", it is possible to enable SND_SOC_FSL_SSI and SND_SOC_FSL_SPDIF
manually, either as loadable modules or built-in. This unfortunately
leads to a link error if one or both of them are built-in, while
the imx-pcm-dma framework is a loadable module:
sound/built-in.o: In function `fsl_ssi_probe':
:(.text+0x51fb8): undefined reference to `imx_pcm_dma_init'
sound/built-in.o: In function `fsl_spdif_probe':
:(.text+0x52e20): undefined reference to `imx_pcm_dma_init'
This changes Kconfig to prevent this case by using 'select' to turn
on the imx-pcm-dma code from both drivers. For consistency, we also
turn on the imx-pcm-fiq code, which is an alternative to the dma
implementation.
Note that imx-pcm-fiq is platform dependent, so we must not enable
that unless we are building a kernel for i.MX. Note also the
"if SND_IMX_SOC != n" syntax as opposed to the normal "if SND_IMX_SOC".
This is needed to avoid turning on the options as 'm' if 'SND_IMX_SOC'
is a module.

The cx20442 codec driver used here requires the TTY layer to
be enabled, or we get a link error:
sound/built-in.o: In function `cx20442_codec_remove':
cx20442.c:398: undefined reference to `tty_hangup'
sound/built-in.o: In function `ams_delta_remove':
ams-delta.c:613: undefined reference to `tty_unregister_ldisc'
sound/built-in.o: In function `ams_delta_cx20442_init':
ams-delta.c:559: undefined reference to `tty_register_ldisc'
This adds the missing dependency in the E3 configuration, there
was already one for the codec.

This codec requires I2C to be enabled, so any other option
that selects it should also depend on I2C.

Commit 2ee57d58735 ("dm cache: add passthrough mode") inadvertently
removed the deferred set reference that was taken in cache_map()'s
writethrough mode support. Restore taking this reference.
This issue was found with code inspection.
