The second patch needs a small modification.
The return value of `__vmap_pages_range_noflush` at Line 181 (https://github.com/google/kmsan/commit/cb9e33e0cd7ff735bc302ff69c02274f24060cff#diff-6c23520766ef70571c16b74ed93474716645c7ba81dc07028c076b6fd5ad2731R181) should also be assigned to `mapped`. With this modification, the patch works.
