Subject: [PATCH] nestedhvm: do not send IPIs twice
Date: Fri, 19 Aug 2011 13:24:43 +0200 [thread overview]
Message-ID: <4E4E47FB.8090807@amd.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 448 bytes --]
In p2m_get_nestedp2m() there is no need to send IPIs via
nestedhvm_vmcx_flushtlb() since p2m_flush_table() already
did that.
