With ARCH_OMAP2PLUS being separated out into OMAP2/3/4/5 etc all the TI device
tree blobs are built no matter the combination of SoCs that are enabled. This
often causes a bunch of irrelevant .dts to be built on a multi platform kernel,
this enables the building of just the ones relevant to the SoCs that are
actually enabled. It also orders the dts file alphabetically.
This also helps to avoid trivial merge conflicts when adding support
for new boards.

Following arm64 commit bc3ee18a7a (arm64: init: Move of_clk_init to

Commit d57c33c5da (add generic fixmap.h) added (among other
similar things) set_fixmap_io to deal with early ioremap of devices.
More recently, commit bf4b558eba (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.

The cause is that the triggers are protected by rcu_read_lock_sched() but
the data is dereferenced with rcu_dereference() which expects it to
be protected with rcu_read_lock(). The proper reference should be
rcu_dereference_sched().

- 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.

from Srivatsa S Bhat.

This branch fixes a bug where a device can get stuck in the deferred
list even though all its dependencies are met. The bug has existed for a
long time, but new platform conversions to device tree have exposed it.
This patch is needed to get those platforms working.
