2023-10-31drm/nouveau/gsp/r535: add support for booting GSP-RMBen Skeggs
This commit adds the initial code needed to boot the GSP-RM firmware provided by NVIDIA, bringing with it the beginnings of Ada support. Until it's had more testing and time to bake, support is disabled by default (except on Ada). GSP-RM usage can be enabled by passing the "config=NvGspRm=1" module option.

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks Pull RCU updates from Frederic Weisbecker: - RCU torture, locktorture and generic torture infrastructure updates that include various fixes, cleanups and consolidations. Among the user visible things, ftrace dumps can now be found into their own file, and module parameters get better documented and reported on dumps. - Generic and misc fixes all over the place. Some highlights: * Hotplug handling has seen some light cleanups and comments * An RCU barrier can now be triggered through sysfs to serialize memory stress testing and avoid OOM * Object information is now dumped in case of invalid callback invocation * Also various SRCU issues, too hard to trigger to deserve urgent pull requests, have been fixed - RCU documentation updates - RCU reference scalability test minor fixes and doc improvements. - RCU tasks minor fixes - Stall detection updates. Introduce RCU CPU Stall notifiers that allows a subsystem to provide informations to help debugging.
