[PATCH 0/3] ARC fixes for 6.12

Hi, Changes slated for a near future rc. Thx, -Vineet Benjamin Szőke (1): arc: rename aux.h to arc_aux.h Paul E. McKenney (1): ARC: build: Use __force to suppress per-CPU cmpxchg warnings Vineet Gupta (1): ARC: build: disallow invalid PAE40 + 4K page config arch/arc/Kconfig

[PATCH 2/3] ARC: build: disallow invalid PAE40 + 4K page config

The config option being built was | CONFIG_ARC_MMU_V4=y | CONFIG_ARC_PAGE_SIZE_4K=y | CONFIG_HIGHMEM=y | CONFIG_ARC_HAS_PAE40=y This was hitting a BUILD_BUG_ON() since a 4K page can't hoist 1k, 8-byte PTE entries (8 byte due to PAE40). BUILD_BUG_ON() is a good last ditch resort, but such a config
