Subject: mm/madvise: add MF_ACTION_REQUIRED to madvise(MADV_HWPOISON)
Date: Fri, 24 May 2024 15:53:03 -0600

The soft hwpoison injector via madvise(MADV_HWPOISON) operates in a
synchrous way in a sense, the injector is also a process under test, and
should it have the poisoned page mapped in its address space, it should
get killed as much as in a real UE situation.  Doing so align with what
the madvise(2) man page says: " "This operation may result in the calling
process receiving a SIGBUS and the page being unmapped."
