As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() and pci_enable_msix_range()
interfaces.

I think it would be better to have 'if (result != op->value)', in case
op->value is negative (which presumably it should never be).

Better yet, at the top of the routine we check 'if (op->value >
SH_INFO_MAX_VEC)'. If you add '|| op->value < 0' we'd be all set.

Ah, OK --- then 'if (op->value > SH_INFO_MAX_VEC)' alone will catch this
(hopefully its' not in billions).

Hi Boris et al,
Based on recently accepted to the mainline pci_enable_msix_exact() function,
I am sending a updated version of the patch. Please, let me know if it does
not work for you and you need and incremental update from the previous version.

This should go into the Xen tree. Konrad is usually the one putting
together pull requests for Linus.
I don't think this needs to go in right away so presumably this will be
queued for the next merge window (unless Konrad has other things for
next RCs and decides to tack this onto other patches).
