Do you have any nouveau/Kconfig patches that might conflict? Thanks Does this fix the randconfigs failures that have been reported? > diff --git a/mm/Kconfig b/mm/Kconfig > index 406fa45e9ecc..4dbd718c8cf4 100644 > +++ b/mm/Kconfig > @@ -677,13 +677,13 @@ config ARCH_HAS_HMM_MIRROR > > config ARCH_HAS_HMM > bool > - default y > depends on (X86_64 || PPC64) > depends on ZONE_DEVICE > depends on MMU && 64BIT > depends on MEMORY_HOTPLUG > depends on MEMORY_HOTREMOVE > depends on SPARSEMEM_VMEMMAP > + default y What is the reason we have this ARCH thing anyhow? Does hmm have arch dependencies someplace?
