comment "VME Bridge Drivers" config VME_CA91CX42 tristate "Universe II" depends on VIRT_TO_BUS help If you say Y here you get support for the Tundra CA91C142 (Universe II) VME bridge chip. config VME_TSI148 tristate "Tempe" depends on HAS_DMA help If you say Y here you get support for the Tundra TSI148 VME bridge chip. config VME_FAKE tristate "Fake" help If you say Y here you get support for the fake VME bridge. This provides a virtualised VME Bus for devices with no VME bridge. This is mainly useful for VME development (in the absence of VME hardware). t.cgi/linux/net-next.git' title='net-next.git Git repository'/>

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.
