I have that all merged up on top of linux-next. Numerous minor conflicts, mainly in arch/arm/Kconfig. Also the changes in https://lkml.kernel.org/r/20201103175841.3495947-7-elver@google.com had to be fed into "kasan: split out shadow.c from common.c". I staged it after linux-next to provide visibility into potentially conflicting changes in the arm tree as things move forward.
