Subject: [PATCH v4 02/12] KVM: arm/arm64: extend arch CAP checks to allow per-VM capabilities
Date: Sat, 26 Mar 2016 02:14:00 +0000	[thread overview]
Message-ID: <1458958450-19662-3-git-send-email-andre.przywara@arm.com> (raw)
In-Reply-To: <1458958450-19662-1-git-send-email-andre.przywara@arm.com>

KVM capabilities can be a per-VM property, though ARM/ARM64 currently
does not pass on the VM pointer to the architecture specific
capability handlers.
Add a "struct kvm*" parameter to those function to later allow proper
per-VM capability reporting.
