Subject: [PATCH v3 01/10] AArch64: Reserve two 64k pages for GIC CPU interface
Date: Wed, 17 Jun 2015 12:21:52 +0100 [thread overview]
Message-ID: <1434540121-21283-2-git-send-email-andre.przywara@arm.com> (raw)
In-Reply-To: <1434540121-21283-1-git-send-email-andre.przywara@arm.com>
From: Marc Zyngier <marc.zyngier@arm.com>
On AArch64 system with a GICv2, the GICC range can be aligned
to the last 4k block of a 64k page, ending up straddling two
64k pages. In order not to conflict with the distributor mapping,
allocate two 64k pages to the CPU interface.
