Commit 1c9df907da83 ("random: fix circular include dependency on arm64 after addition of percpu.h")
exposed a curcular include dependency: asm/mmu.h includes asm/percpu.h, which includes asm/paca.h, which includes asm/mmu.h So fix it by extracting the small part of asm/mmu.h that needs asm/percu.h into a new file and including that where necessary.
