Subject: [PATCH v7 11/13] KVM: arm/arm64: Add KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION
Date: Sun, 20 May 2018 23:22:50 +0200	[thread overview]
Message-ID: <1526851372-13009-12-git-send-email-eric.auger@redhat.com> (raw)
In-Reply-To: <1526851372-13009-1-git-send-email-eric.auger@redhat.com>

This new attribute allows the userspace to set the base address
of a reditributor region, relaxing the constraint of having all
consecutive redistibutor frames contiguous.

Signed-off-by: Eric Auger <eric.auger@redhat.com>
Acked-by: Christoffer Dall <christoffer.dall@arm.com>

v3 -> v4:
- keep previous indentation for existing attributes
- added Christoffer's A-b
