#     random: fix circular include dependency on arm64 after addition of percpu.h
#     
#     Daniel Díaz and Kees Cook independently reported that commit
#     f227e3ec3b5c ("random32: update the net random state on interrupt and
#     activity") broke arm64 due to a circular dependency on include files
#     since the addition of percpu.h in random.h.
#     
#     The correct fix would definitely be to move all the prandom32 stuff out
#     of random.h but for backporting, a smaller solution is preferred.
#     
#     This one replaces linux/percpu.h with asm/percpu.h, and this fixes the
#     problem on x86_64, arm64, arm, and mips.  Note that moving percpu.h
#     around didn't change anything and that removing it entirely broke
#     differently.  When backporting, such options might still be considered
#     if this patch fails to help.
#     
#     [ It turns out that an alternate fix seems to be to just remove the
#       troublesome <asm/pointer_auth.h> remove from the arm64 <asm/smp.h>
#       that causes the circular dependency.
#     
#       But we might as well do the whole belt-and-suspenders thing, and
#       minimize inclusion in <linux/random.h> too. Either will fix the
#       problem, and both are good changes.   - Linus ]
