As such, I'd like to take another opportunity to thank them for their many years of effort maintaining XFS and supporting the XFS community that they developed from the ground up. So I haven't had time to work things like signed tags into my workflows yet, so this is just a repo branch I'm asking you to pull from. And yes, I named the branch -rc4 because I wanted the fixes in rc4, not because the branch was for merging into -rc3. Probably not right, either. Anyway, I should have everything sorted out by the time the next merge window comes around. If there's anything that you don't like in the pull req, feel free to flame me unmercifully.

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() Revert "of: search the best compatible match first in __of_match_node()"

2014-02-21perf/x86: Correctly use FEATURE_PDCMPeter Zijlstra
The current code simply assumes Intel Arch PerfMon v2+ to have the IA32_PERF_CAPABILITIES MSR; the SDM specifies that we should check CPUID[1].ECX[15] (aka, FEATURE_PDCM) instead. This was found by KVM which implements v2+ but didn't provide the capabilities MSR. Change the code to DTRT; KVM will also implement the MSR and return 0.

2014-02-21usb: chipidea: need to mask when writting endptflush and endptprimeMatthieu CASTET
ENDPTFLUSH and ENDPTPRIME registers are set by software and clear by hardware. There is a bit for each endpoint. When we are setting a bit for an endpoint we should make sure we do not touch other endpoint bit. There is a race condition if the hardware clear the bit between the read and the write in hw_write.

2014-02-21staging: binder: Fix death notificationsArve Hjønnevåg
The change (008fa749e0fe5b2fffd20b7fe4891bb80d072c6a) that moved the node release code to a separate function broke death notifications in some cases. When it encountered a reference without a death notification request, it would skip looking at the remaining references, and therefore fail to send death notifications for them.

2014-02-21sched/deadline: Remove useless dl_nr_totalKirill Tkhai
In deadline class we do not have group scheduling like in RT. dl_nr_total is the same as dl_nr_running. So, one of them should be removed.

2014-02-21sched/deadline: Test for CPU's presence explicitlyBoris Ostrovsky
A hot-removed CPU may have ID that is numerically larger than the number of existing CPUs in the system (e.g. we can unplug CPU 4 from a system that has CPUs 0, 1 and 4). Thus the WARN_ONs should check whether the CPU in question is currently present, not whether its ID value is less than num_present_cpus().

2014-02-21sched: Add 'flags' argument to sched_{set,get}attr() syscallsPeter Zijlstra

2014-02-21sched: Fix information leak in sys_sched_getattr()Vegard Nossum
We're copying the on-stack structure to userspace, but forgot to give the right number of bytes to copy. This allows the calling process to obtain up to PAGE_SIZE bytes from the stack (and possibly adjacent kernel memory). This fix copies only as much as we actually have on the stack (attr->size defaults to the size of the struct) and leaves the rest of the userspace-provided buffer untouched. Found using kmemcheck + trinity.
