Subject: [PATCH] xen: arm32: Use system wide TLB flushes, not just inner-shareable
Date: Fri, 8 Feb 2013 15:40:56 +0000 [thread overview]
Message-ID: <1360338056-31812-1-git-send-email-ian.campbell@citrix.com> (raw)
We currently setup page table walks etc as outer-shareable. Given we don't
really make the distinction between inner- and outer-shareable yet err on
theside of safety.
