Are you serious ? This problem literally affects all branches, starting
with v4.4.y. And, yes, the powerpc builds fail as well for all branches.
Just like mainline. I guess that means it doesn't matter either ?

Building powerpc:ppc64e_defconfig ... failed
--------------
Error log:
In file included from arch/powerpc/include/asm/paca.h:22,
                 from arch/powerpc/include/asm/percpu.h:13,
                 from include/linux/random.h:12,
                 from lib/uuid.c:22:
arch/powerpc/include/asm/mmu.h:131:22: error: unknown type name 'next_tlbcam_idx'

Congratulations, looks like all stable releases are "bug for bug compatible"
with mainline.

Does it even make sense to provide full reports for this set of releases ?
