Merge tag 'arc-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC updates from Vineet Gupta:
"Finally a big pile of changes for ARC (atomics/mm). These are from our
internal arc64 tree, preparing mainline for eventual arc64 support.
I'm spreading them out to avoid tsunami of patches in one release.
- MM rework:
- Implement up to 4 paging levels
- Enable STRICT_MM_TYPECHECK
- switch pgtable_t back to 'struct page *'
- Atomics rework / implement relaxed accessors
- Retire legacy MMUv1,v2; ARC750 cores
- A few other build errors, typos"
