Brian, did you have any comments on this series? ARCH=hexagon defconfig 
is currently broken in -next, it would be a real shame if this continued 
to regress after you just got Hexagon building in mainline. These 
patches seem like they would be worthy of a 5.13 pull request. 
Otherwise, Andrew could pick them up with your ack and stick them in 
front of "mm/slub: use stackdepot to save stack trace in objects" so 
that there is no build regression.

Cheers,
Nathan
