	tristate "IEEE Std 802.15.4 Low-Rate Wireless Personal Area Networks support"
	---help---
	  IEEE Std 802.15.4 defines a low data rate, low power and low
	  complexity short range wireless personal area networks. It was
	  designed to organise networks of sensors, switches, etc automation
	  devices. Maximum allowed data rate is 250 kb/s and typical personal
	  operating space around 10m.

	  Say Y here to compile LR-WPAN support into the kernel or say M to
	  compile it as modules.

tracing: Fix hwlat kthread migration
The hwlat tracer creates a kernel thread at start of the tracer. It is pinned to a single CPU and will move to the next CPU after each period of running. If the user modifies the migration thread's affinity, it will not change after that happens. The original code created the thread at the first instance it was called, but later was changed to destroy the thread after the tracer was finished, and would not be created until the next instance of the tracer was established. The code that initialized the affinity was only called on the initial instantiation of the tracer. After that, it was not initialized, and the previous affinity did not match the current newly created one, making it appear that the user modified the thread's affinity when it did not, and the thread failed to migrate again.
