The extension is necessary right now because we need a proper way to unbreak LTTNG, which iscurrently non functional due to the removal of the notifiers. Surely it's out of tree, but it's widely used by distros. The simple solution would have been to reserve a state for LTTNG, but I'm not fond about unused crap in the kernel and the dynamic range, which we admittedly should have done right away, allows us to remove quite some of the hardcoded states, i.e. those which have no ordering requirements.

commit d32932d02e18 removed the irq_retrigger callback from the IO-APIC chip and did not add it to the new IO-APIC-IR irq chip. Unfortunately the software resend fallback is not enabled on X86, so edge interrupts which are received during the lazy disabled state of the interrupt line are not retriggered and therefor lost.

2017-01-18ovl: fix possible use after free on redirect dir lookupAmir Goldstein
ovl_lookup_layer() iterates on path elements of d->name.name but also frees and allocates a new pointer for d->name.name. For the case of lookup in upper layer, the initial d->name.name pointer is stable (dentry->d_name), but for lower layers, the initial d->name.name can be d->redirect, which can be freed during iteration. [SzM] Keep the count of remaining characters in the redirect path and calculate the current position from that. This works becuase only the prefix is modified, the ending always stays the same.

2017-01-17Input: tca8418 - use the interrupt trigger from the device treeMaxime Ripard
The TCA8418 might be used using different interrupt triggers on various boards. This is not working so far because the current code forces a falling edge trigger. The device tree already provides a trigger type, so let's use whatever it sets up, and since we can be loaded without DT, keep the old behaviour for the non-DT case.
