Subject: [PATCH 2/5] xen/xsm: Complete altcall conversion of xsm interface
Date: Fri, 5 Nov 2021 13:55:52 +0000 [thread overview]
Message-ID: <20211105135555.24261-3-andrew.cooper3@citrix.com> (raw)
In-Reply-To: <20211105135555.24261-1-andrew.cooper3@citrix.com>
With alternative_call() capable of handling compound types, the three
remaining hooks can be optimised at boot time too.

I'm on the fence as to whether to declare this as fixing "xsm: convert xsm_ops
hook calls to alternative call"
