+Subject: [PATCH] trace: fix build with gcc9
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+While I've not observed this myself, gcc 9 (imo validly) reportedly may
+complain
+
+trace.c: In function '__trace_hypercall':
+trace.c:826:19: error: taking address of packed member of 'struct <anonymous>' may result in an unaligned pointer value [-Werror=address-of-packed-member]
+  826 |     uint32_t *a = d.args;
+
+and the fix is rather simple - remove the __packed attribute. Introduce
+a BUILD_BUG_ON() as replacement, for the unlikely case that Xen might
+get ported to an architecture where array alignment higher that that of
+its elements.

+Subject: [PATCH] xen/arm: Cap the number of interrupt lines for dom0
+
+Dom0 vGIC will use the same number of interrupt lines as the hardware GIC.
+While the hardware GIC can support up to 1020 interrupt lines,
+the vGIC is only supporting up to 992 interrupt lines.
+This means that Xen will not be able to boot on platforms where the hardware
+GIC supports more than 992 interrupt lines.
+While it would make sense to increase the limits in the vGICs, this is not
+trivial because of the design choices.
+At the moment, only models seem to report the maximum of interrupt lines.
+They also do not have any interrupt wired above the 992 limit.
+So it should be fine to cap the number of interrupt lines for dom0 to 992 lines.
