[PATCH 0/3] Add pci_enable_msi_partial() to conserve MSI-related resources

[Alexander Gordeev]

Add new pci_enable_msi_partial() interface and use it to
conserve on othewise wasted interrupt resources.

AHCI driver is the first user which would conserve on
10 out of 16 unused MSI vectors on some Intel chipsets.
