Newer versions of Intel PT support address ranges, which can be used to define IP address range-based filters or TraceSTOP regions. Number of ranges in enumerated via cpuid. This patch implements PMU callbacks and related low-level code to allow filter validation, configuration and programming into the hardware.

Many instruction tracing PMUs out there support address range-based filtering, which would, for example, generate trace data only for a given range of instruction addresses, which is useful for tracing individual functions, modules or libraries. Other PMUs may also utilize this functionality to allow filtering to or filtering out code at certain address ranges. This patch introduces the interface for userspace to specify these filters and for the PMU drivers to apply these filters to hardware configuration. The user interface is an ASCII string that is passed via an ioctl() and specifies (in the form of an ASCII string) address ranges within certain object files or within kernel. There is no special treatment for kernel modules yet, but it might be a worthy pursuit. The PMU driver interface basically adds two extra callbacks to the PMU driver structure, one of which validates the filter configuration proposed by the user against what the hardware is actually capable of doing and the other one translates hardware-independent filter configuration into something that can be programmed into the hardware.

Both of these drivers can return NOTIFY_BAD, but this terminates processing other callbacks that were registered later on the chain. Since the driver did nothing to log the error it seems wrong to prevent other interested parties from seeing it.

Kcov causes the compiler to add a call to __sanitizer_cov_trace_pc() in every basic block. Ftrace patches in a call to _mcount() to each function it has annotated. Letting these mechanisms annotate each other is a bad thing. Break the loop by adding 'notrace' to __sanitizer_cov_trace_pc() so that ftrace won't try to patch this code. This patch lets arm64 with KCOV and STACK_TRACER boot.

When kswapd goes to sleep it checks if the node is balanced and at first it sleeps only for HZ/10 time, then rechecks if the node is still balanced and nobody has woken it during the initial sleep. Only then it goes fully sleep until an allocation slowpath wakes it up again. For higher-order allocations, waking up kcompactd is done only before the full sleep. This turns out to be an issue in case another high-order allocation fails during the initial sleep. It will wake kswapd up, however kswapd considers the zone balanced from the order-0 perspective, and will just quickly try to sleep again. So if there's a longer stream of high-order allocations hitting the slowpath and waking up kswapd, it might never actually wake up kcompactd, which may be considered a regression from kswapd-based compaction. In the worst case, it might be that a single allocation that cannot direct reclaim/compact itself is waking kswapd in the retry loop and preventing kcompactd from being woken up and unblocking it. This patch makes sure kcompactd is woken up in such situations by simply moving the wakeup before the short initial sleep. More efficient solution would be to wake kcompactd immediately instead of kswapd if the node is already order-0 balanced, but in that case we should also move reset_isolation_suitable() call to kcompactd so it's not adding to the allocator's latency. Since it's late in the 4.6 cycle, let's go with the simpler change for now.
