Insert KMSAN hooks that make the necessary bookkeeping changes: - poison page shadow and origins in alloc_pages()/free_page(); - clear page shadow and origins in clear_page(), copy_user_highpage(); - copy page metadata in copy_highpage(), wp_page_copy(); - handle vmap()/vunmap()/iounmap(); Signed-off-by: Alexander Potapenko <glider@google.com> Link: https://linux-review.googlesource.com/id/I08e2eed033c47fc754155fe8b2e8cbfd24577075 --- This patch was previously called "kmsan: call KMSAN hooks where needed" v2: - dropped call to kmsan_handle_vprintk, updated comment in printk.c v3: - put KMSAN_INIT_VALUE on a separate line in vprintk_store() - dropped call to kmsan_handle_i2c_transfer() - minor style fixes v4: - split mm-unrelated bits to other patches as requested by Andrey Konovalov - dropped changes to mm/compaction.c - use kmsan_unpoison_shadow in page_64.h and highmem.h v6: - switch to eager metadata allocation - switch to new KMSAN memory mapping/unmapping API that matches mm/vmalloc.c - use new poisoning API names - revert mm/ioremap.c
