Re-arrange the two "offending" if()s such that when COMPAT=n the respective variables will be seen as unconditionally initialized. The original aim was to have the !compat cases first, though.

Xen should read/write SPSR instead. See: ARM DDI 0487D.b page G8-5993. This fixes booting Xen/arm32 on QEMU. Signed-off-by: Stefano Stabellini Reviewed-by: Julien Grall Reviewed-by: Edgar E.
