Subject: [PATCH 03/13] powerpc/powernv: Define real-mode versions of OPAL XICS accessors
Date: Fri, 18 Nov 2016 18:28:32 +1100	[thread overview]
Message-ID: <1479454122-26994-4-git-send-email-paulus@ozlabs.org> (raw)
In-Reply-To: <1479454122-26994-1-git-send-email-paulus@ozlabs.org>

This defines real-mode versions of opal_int_get_xirr(), opal_int_eoi()
and opal_int_set_mfrr(), for use by KVM real-mode code.

It also exports opal_int_set_mfrr() so that the modular part of KVM
can use it to send IPIs.
