mlx5 dynamic msix
 
 This patch series adds support for dynamic msix vectors allocation in mlx5.
 
 Eli Cohen Says:
 
 ================
 
 The following series of patches modifies mlx5_core to work with the
 dynamic MSIX API. Currently, mlx5_core allocates all the interrupt
 vectors it needs and distributes them amongst the consumers. With the
 introduction of dynamic MSIX support, which allows for allocation of
 interrupts more than once, we now allocate vectors as we need them.
 This allows other drivers running on top of mlx5_core to allocate
 interrupt vectors for their own use. An example for this is mlx5_vdpa,
 which uses these vectors to propagate interrupts directly from the
 hardware to the vCPU [1].
 
 As a preparation for using this series, a use after free issue is fixed
 in lib/cpu_rmap.c and the allocator for rmap entries has been modified.
 A complementary API for irq_cpu_rmap_add() has also been introduced.
