** Description changed:
In some cases it may happen that pmd_none_or_clear_bad() is called with
the mmap_sem hold in read mode. In those cases the huge page faults can
allocate hugepmds under pmd_none_or_clear_bad() and that can trigger a
false positive from pmd_bad() that will not like to see a pmd
materializing as trans huge. A privileged user in the KVM guest can use
this flaw to crash the host. An unprivileged local user could use this
flaw to crash the system.
