...Xen. The future Ian Campbel''s patch series should resolve this issue. The major changes are: - Introduce init_info structure to gather all CPU boot informations All changes can be found in each patch. Cheers, Julien Grall (7): xen/arm: Introduce init_info structure xen/arm: use cpumask_t to describe cpu mask in gic_route_dt_irq xen/arm: Initialize correctly IRQ routing xen/arm: gic: Use the correct CPU ID xen/arm: Fix assert in send_SGI_one xen/arm: Dissociate logical and hardware CPU ID xen/arm: Use the hardware ID to boot correctly secondary cpus xen/arch/arm/arm32/as...

This patch defines a test_and_clear bitop for cpumask_t pointers. Also fixes "wrong pointer type" for type specific bitops by using &foo [0] instead of &foo.
