Subject: [PATCH 2/5] KVM: arm64: Drop init_common_resources()
Date: Tue, 10 Aug 2021 12:32:38 +0530 [thread overview]
Message-ID: <1628578961-29097-3-git-send-email-anshuman.khandual@arm.com> (raw)
In-Reply-To: <1628578961-29097-1-git-send-email-anshuman.khandual@arm.com>
Could do without this additional indirection via init_common_resources() by
just calling kvm_set_ipa_limit() directly instead. This change saves memory
and cycles.
