I got a similar problem when I applied your patch on top of the vgic
stuff.

Moving the cpumask to the end solved it for my case, but that was for
offset 0x4c4 IIRC: this looks different.  We may have to rewrite that
part of the asm to use multiple instructions...

Thanks, I will enable more kernel debugging options and fix what this patch breaks.
 

Cheers,
Rusty.
