Hi,
With support for contiguous hugepages being turned off[0], some of the
problems arising from swap entries go away[1]. This simplifies the
changes needed to enable memory corruption handling for arm64 (done in
this seris).
In this series, we updates huge_pte_offset() to correctly deal with
swap entries (Patch 1). This function will need to be updated when
contiguous hugepages are re-enabled.
Patch 2 adds support to send SIGBUS to processes that have their
memory corrupted. With the prerequisites in place, enable memory
corruption handling for arm64 (patch 3).
Thanks,
Punit
