I had removed that commit for the duration of the merge window, and forgotten about it when I re-added all my non-3.19 commits. :-/ Could you please send your .config? Or let me know whether it has CONFIG_KVM=n? Pranith, if Stephen has CONFIG_KVM=n, it might be best to move the "select SRCU" to "config PPC" in arch/powerpc/Kconfig. Are you able to cross-build powerpc? Thanx, Paul
