2014-05-06ARM: dts: Only build OMAP dtb if associated SoC is builtPeter Robinson
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.

2014-05-04vexpress: Initialise the sysregs before setting up the clocksCatalin Marinas
Following arm64 commit bc3ee18a7a57 (arm64: init: Move of_clk_init to time_init()), vexpress_osc_of_setup() is called via of_clk_init() long before initcalls are issued. Initialising the vexpress oscillators requires the vespress sysregs to be already initialised, so this patch adds an explicit call to vexpress_sysreg_of_early_init() in vexpress oscillator setup function.

2014-05-03arm64: fixmap: fix missing sub-page offset for earlyprintkMarc Zyngier
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.

2014-05-03arm64: Fix for the arm64 kern_addr_valid() functionDave Anderson
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().

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.

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" * tag 'pm+acpi-3.15-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / processor: Fix failure of loading acpi-cpufreq driver PNP / ACPI: Do not return errors if _DIS or _SRS are not present PNP: Fix compile error in quirks.c ACPI / EC: Process rather than discard events in acpi_ec_clear cpufreq: ppc-corenet-cpufreq: Fix __udivdi3 modpost error cpufreq: powernow-k7: Fix double invocation of cpufreq_freq_transition_begin/end cpufreq: powernow-k6: Fix double invocation of cpufreq_freq_transition_begin/end cpufreq: powernow-k6: Fix incorrect comparison with max_multipler cpufreq: longhaul: Fix double invocation of cpufreq_freq_transition_begin/end

Pull driver core deferred probe fix from Grant Likely: "Drivercore race condition fix (exposed by devicetree) 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. This was the pending bug fix I mentioned in my previous pull request. Normally this would go through Greg's tree seeing that it is a drivercore change, but devicetree exposes the problem. I've discussed with Greg and he okayed me asking you to pull directly" * tag 'dt-for-linus' of git://git.secretlab.ca/git/linux: drivercore: deferral race condition fix
