Subject: powerpc: build failures in Linus' tree

Hi all,

We are getting build failures in some PowerPC configs for Linus' tree.
See e.g. http://kisskb.ellerman.id.au/kisskb/buildresult/14306515/

In file included from /kisskb/src/arch/powerpc/include/asm/paca.h:18,
                 from /kisskb/src/arch/powerpc/include/asm/percpu.h:13,
                 from /kisskb/src/include/linux/random.h:14,
                 from /kisskb/src/include/linux/net.h:18,
                 from /kisskb/src/net/ipv6/ip6_fib.c:20:
/kisskb/src/arch/powerpc/include/asm/mmu.h:139:22: error: unknown type name 'next_tlbcam_idx'
  139 | DECLARE_PER_CPU(int, next_tlbcam_idx);

I assume this is caused by commit

  1c9df907da83 ("random: fix circular include dependency on arm64 after addition of percpu.h")

But I can't see how, sorry.
