Subject: [PATCH v3 02/11] x86/hvm: drop domain parameter from vioapic/vpic EOI callbacks
Date: Wed, 31 Mar 2021 12:32:54 +0200 [thread overview]
Message-ID: <20210331103303.79705-3-roger.pau@citrix.com> (raw)
In-Reply-To: <20210331103303.79705-1-roger.pau@citrix.com>
EOIs are always executed in guest vCPU context, so there's no reason to
pass a domain parameter around as can be fetched from current->domain.
No functional change intended.
