Hi Paul,
Today's linux-next merge of the rcu tree got a conflict in arch/Kconfig
arch/x86/Kconfig between commit d673c23ca730 ("Make most arch
asm/module.h files use asm-generic/module.h") from the rr tree and commits
3dbdfc26e27f ("rcu: Settle config for userspace extended quiescent
state") and 1ea856be75ce ("x86: Exit RCU extended QS on notify resume")
from the rcu tree.
Just context changes. I fixed it up (see below) and can carry the fix as
necessary.
