Subject: [PATCH 0/1] arch/fault: don't print logs for simulated poison errors

This patch expects to be applied on top of both of the following related
fixes:

- x86/fault: speed up uffd-unit-test by 10x: rate-limit "MCE: Killing" logs
  https://lore.kernel.org/r/20240507022939.236896-1-jhubbard@nvidia.com
- [0/2] Minor fixups for hugetlb fault path
  https://lore.kernel.org/r/20240509100148.22384-1-osalvador@suse.de

The latter is in mm-unstable currently, but the former is not (yet?). It
would need to be taken before this patch for it to apply cleanly.
