These VPRINKs are only to make new handlers look like ahci_interrupt()
which did not change. I believe, if they need to go it is better to
remove them altogether, with a separate followup pa

As DPRINTKs/VPRINTKs are all over the ATA stack, I do not really realize
why it should be eliminated in one places (i.e. in hardware handlers) and
left in anothers. So as long as you would not like to remove them all, I
would leave it as is for now.
Does it make sense for you?

Ah.. sorry - Jeff acked v3, not the recen
IRQ and PCI subsystems are modified, the current behaviour left
intact. The drivers could just start using multiple MSIs just by following
the existing documentation.
The patches are adapted to Ingo's -tip repository, x86/apic branch.

The minimum number of MSI-Xs is (MLX5_EQ_VEC_COMP_BASE + 1) in
one check and 2 in another check. Make the checks consistent and
assume the minimum number is (MLX5_EQ_VEC_COMP_BASE + 1).

Multiple MSIs have never been supported on s390 architecture,
but the platform code fails to report single MSI only.

Current MSI-X enablement code assumes MSI-Xs were successfully
allocated in case less than requested vectors were available.
That assumption is wrong, since MSI-Xs should be enabled with
a repeated call to pci_enable_msix(). This update fixes this.

pci_msix_table_size() for MSI-X.
More complex cases would entail matching device capabilities
with the system environment, i.e. limiting number of hardware
queues (and hence associated MSI/MSI-X interrupts) to the number
of online CPUs.
