Subject: Re: [PATCH v2 2/6] PCI/MSI: Factor out pci_get_msi_cap() interface

Michael et al.

The identifiable options sounded so far were:

* Do not change anything

* Make pci_enable_msix() return 0/-errno

* Make pci_enable_msix() return 0/-errno and introduce arch_get_msix_limit()/
  arch_get_msi_limit()

* Make pci_enable_msix() return 0/-errno and introduce pci_get_msix_limit()/
  pci_get_msi_limit() and arch_get_msix_limit()/arch_get_msi_limit() so that:
	pci_get_msix_limit() = min(arch_get_msix_limit(), pci_msix_table_size())
	pci_get_msi_limit()  = min(arch_get_msi_limit(),  pci_get_msi_cap())

Can we have a conclusion here?

Thanks!
