Xen 4.9

9630c5ae363b4cbf8eb61366530f40c80680af4d xen/arm: gic-v3: Bail out if 
gicv3_cpu_init fail
c05aa4afac64ea687c1a2bf9277ba6552809495b xen/arm: bootfdt: Use proper default 
for #address-cells and #size-cells

non-secure group1
abd91b2a2bcd05618a71f7e5fe571dd10a5727bc xen/arm: p2m: Check for p2m->domain to 
be initialized before releasing resources
b1f1e492cd4231a1e9feedb7a35c62c063f7c510 xen/arm: vgic: Check for vgic handler 
to be initialized before dereferencing it

Xen 4.8

43208a9cb4c3decce67b653539c1b860121fbb5e ARM: vGIC: avoid rank lock when 
reading priority
        => Require ACCESS_ONCE that is not globally available in Xen 4.8.
        I am undecided we want that patch, it is a real bug but it would pull a 
bit more code.
