Subject: Re: [PATCH v8 10/11] arm64/kasan: explicitly zero kasan shadow memory
Date: Thu, 14 Sep 2017 21:30:28 -0400 [thread overview]
Message-ID: <c76f72fc-21ed-62d0-014e-8509c0374f96@oracle.com> (raw)
In-Reply-To: <20170915011035.GA6936@remoulade>
Hi Mark,
Thank you for looking at this. We can't do this because page table is
not set until cpu_replace_ttbr1() is called. So, we can't do memset() on
this memory until then.
Pasha
