Merge tag 'asm-generic-mmu-context-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic
Pull asm-generic mmu-context cleanup from Arnd Bergmann:
"This is a cleanup series from Nicholas Piggin, preparing for later
changes. The asm/mmu_context.h header are generalized and common code
moved to asm-gneneric/mmu_context.h.
This saves a bit of code and makes it easier to change in the future"
