Subject: [PATCH 0/3] arm64: Add support for handling memory corruption
Date: Wed, 12 Apr 2017 15:04:56 +0100	[thread overview]
Message-ID: <20170412140459.21824-1-punit.agrawal@arm.com> (raw)

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
