The fix that I'm pursuing starts with: diff --git a/include/linux/printk.h b/include/linux/printk.h index 1522df223c0f..8e8d74edf121 100644 --- a/include/linux/printk.h +++ b/include/linux/printk.h @@ -6,7 +6,6 @@ #include <linux/init.h> #include <linux/kern_levels.h> #include <linux/linkage.h> -#include <linux/cache.h> #include <linux/ratelimit_types.h> #include <linux/once_lite.h> and fixing the fallout from code that was including printk.h and depending on something from cache.h. So far I haven't found much, only 3 fixups required for an arm64 defconfig kernel but I'm trying some more configs as well. Peter
