Here is the large set of char and misc and other driver subsystem changes for 6.0-rc1. Highlights include: - large set of IIO driver updates, additions, and cleanups - new habanalabs device support added (loads of register maps much like GPUs have) - soundwire driver updates - phy driver updates - slimbus driver updates - tiny virt driver fixes and updates - misc driver fixes and updates - interconnect driver updates - hwtracing driver updates - fpga driver updates - extcon driver updates - firmware driver updates - counter driver update - mhi driver fixes and updates - binder driver fixes and updates - speakup driver fixes Full details are in the long shortlog contents. All of these have been in linux-next for a while without any reported problems.

Enable RCU lockdep checking for list usages. By default it is

turned off since there are several list RCU users that still

need to be converted to pass a lockdep expression. To prevent

false-positive splats, we keep it default disabled but once all

users are converted, we can remove this config option.

Select this option to build an RCU variant that is strict about
|
|
grace periods, making them as short as it can. This limits
|
|
scalability, destroys real-time response, degrades battery
|
|
lifetime and kills performance. Don't try this on large
|
|
machines, as in systems with more than about 10 or 20 CPUs.
|
|
But in conjunction with tools like KASAN, it can be helpful
|
|
when looking for certain types of RCU usage bugs, for example,
|
|
too-short RCU read-side critical sections.
