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" * tag 'asm-generic-mmu-context-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: (25 commits) h8300: Fix generic mmu_context build m68k: mmu_context: Fix Sun-3 build xtensa: use asm-generic/mmu_context.h for no-op implementations x86: use asm-generic/mmu_context.h for no-op implementations um: use asm-generic/mmu_context.h for no-op implementations sparc: use asm-generic/mmu_context.h for no-op implementations sh: use asm-generic/mmu_context.h for no-op implementations s390: use asm-generic/mmu_context.h for no-op implementations riscv: use asm-generic/mmu_context.h for no-op implementations powerpc: use asm-generic/mmu_context.h for no-op implementations parisc: use asm-generic/mmu_context.h for no-op implementations openrisc: use asm-generic/mmu_context.h for no-op implementations nios2: use asm-generic/mmu_context.h for no-op implementations nds32: use asm-generic/mmu_context.h for no-op implementations mips: use asm-generic/mmu_context.h for no-op implementations microblaze: use asm-generic/mmu_context.h for no-op implementations m68k: use asm-generic/mmu_context.h for no-op implementations ia64: use asm-generic/mmu_context.h for no-op implementations hexagon: use asm-generic/mmu_context.h for no-op implementations csky: use asm-generic/mmu_context.h for no-op implementations ...
