Subject: [PATCH v4 1/6] arm/arm64/xen: hypercall.h add includes guards
Date: Wed,  4 Dec 2019 18:20:53 -0500
Message-ID: <20191204232058.2500117-2-pasha.tatashin@soleen.com> (raw)
In-Reply-To: <20191204232058.2500117-1-pasha.tatashin@soleen.com>

The arm and arm64 versions of hypercall.h are missing the include
guards. This is needed because C inlines for privcmd_call are going to
be added to the files.

Also fix a comment.
