+ uint32_t gic_lr[64];
+ uint64_t event_mask;
+ uint64_t lr_mask;
This has an odd number of uint32_t. I suspect it will end up with a
different structure size between a 32 and 64 bit build of Xen.
I will add a padding field to make all structures 64-bit aligned. Let me
know if this isn't what you want.
