Changes since v1 [3]: - Kirill suggested further decoupling of freeing stack capture from KASAN and debug_pagealloc. Also the stackdepot handle is now only allocated in page_ext when actually used (it was simpler than I initially thought). As that was a large change, I've dropped Reviewed-by from Andrey Ryabinin. - More minor changes suggested by Kirill. These are followups to [1] which made it to Linus meanwhile. Patches 1 and 3 are based on Kirill's review, patch 2 on KASAN request [2]. It would be nice if all of this made it to 5.4 with [1] already there (or at least Patch 1).
