Anyone using this kernel shold apply this x86 fix:

--- a/include/linux/uaccess.h~uaccess-fix-parameters-inversion-for-__copy_from_user_inatomic
+++ a/include/linux/uaccess.h
@@ -78,7 +78,7 @@ static inline unsigned long __copy_from_
 							\
 		set_fs(KERNEL_DS);			\
 		pagefault_disable();			\
-		ret = __copy_from_user_inatomic((__force typeof(retval) __user *)(addr), &(retval), sizeof(retval));		\
+		ret = __copy_from_user_inatomic(&(retval), (__force typeof(retval) __user *)(addr), sizeof(retval));		\
 		pagefault_enable();			\
 		set_fs(old_fs);				\

to prevent a storm of warnings like

[   58.694606] SLAB: cache with size 16384 has lost its name
[   58.694773] SLAB: cache with size 8192 has lost its name

plus probably other more nasty things.
